Early life

Kai and Nya were very young when their parents were taken from them

Kai was born in Ignacia, the first child of a blacksmith named Ray who owned the Four Weapons shop. He and his younger sister, Nya, were raised in their father's craft. Unknown to either of them, their parents were the Elemental Masters of Fire and Water. Kai inherited his father's element of Fire, while Nya inherited their mother's ability of Water though they were unaware of this fact at first.

When Kai and Nya were young, Ray would tell them stories of the dragons, mystical creatures that belonged to both the world of the living and of the dead.[1] He would often teach them proverbs such as "No matter how much fire you have, experience isn't something you learn overnight"[2] and "The world works in mysterious ways.[3] At one point, young Kai and Nya met Wu, a friend of their parents.[4]

Kai working at Four Weapons

When his parents disappeared, Kai took it upon himself to keep the family business going, vowing to surpass his father's blacksmith skills.[2] Kai took care of his sister while wondering all their life what became of their parents.[citation needed] At one point, the two had a babysitter named Grumbmiller, who they disliked and would trip her when she made them go to bed early.[5] Because Grumbmiller's cooking was subpar, Nya would often volunteer to make dinner.[6]

Pilot episodes

Way of the Ninja

One day while working, Kai explains to Nya how to properly make a sword, but becomes too impatient and thus produces a disfigured weapon. He is reminded by his sister to be more patient, but are interrupted when an old man enters the shop. The potential customer voices complaints concerning the lack of tools for Ninja and Kai quickly shooed him away.

Kai and Nya at Four Weapons

Shortly thereafter, Ignacia falls under attack by Samukai and his Skeleton army. Kai attempts to defend them with samurai armor, though it proved to be slow and clunky. While he managed to defeat several skeleton foot soldiers, he was quickly subdued by Samukai. Pinned down by his armor, Kai would have fallen victim to the Skulkin General had the old man—Master Wu—not returned and saved him. However, while they were preoccupied, the skeletons kidnapped Nya and escaped to the Underworld. The young blacksmith intended to go after them, but was stopped by Wu. He explains to Kai the story of the First Spinjitzu Master and his two sons who fought over the four Golden Weapons, explaining that an honest man—Kai's father—had been entrusted with the map to their resting places. Kai is advised by Wu to become a Ninja to save his sister, and Kai reluctantly agrees.

Kai has completed Wu's challenge

Kai is taken to the Monastery of Spinjitzu in order to be trained as a Ninja and learn Spinjitzu. During his training, Kai had to learn patience and how to harness the "fire" inside of him. This training consisted of running a course before Master Wu finishes his tea. Kai accomplished this after several days and does so by knocking the teacup out of his Master's hands when he was about halfway through the course. He is then told by Wu that he had one final test the next day, and should get some sleep.

The Golden Weapon

Kai's first encounter with Jay, Zane, and Cole

Later that night, while Kai is pondering Master Wu's training while brushing his teeth, he is set upon by three black-suited Ninja. Their fight took them out to the courtyard where Kai activates the training course to even the odds. They were quickly stopped by Wu, who revealed that the three Ninja were his students as well. Wu then used Creation to give each of the Ninja a suit that matched their elemental properties and pronounced Kai as the red Master of Fire. After Wu explained their purpose, he announced that they would now leave to claim the first Golden Weapon.

On the way there, Kai and the others explain where and how Master Wu found them. Kai reveals that he is journeying to the Underworld to save his sister, to which Jay replies "We're saving a girl? Is she hot?"

Once arriving at the Caves of Despair, Kai runs ahead of the other Ninja while Cole is still formulating a plan. The others catch up to him at Samukai's watchtower, and after Zane steals the map of Golden Weapons, Kai races ahead again. The other Ninja follow him into one of the caves and find him attempting to remove a large boulder from blocking a hidden room. They do so, and Cole reminded him that they were a team as they moved it together. Inside they find the Scythe of Quakes, and remove it from it's resting place. On their way out, Jay accidentally reveals their position to the skeleton army, and they were soon in a battle. After Jay discovered the key to unlocking his Spinjitzu, Kai and the others were quick to follow. They used it to drive off the skeleton army, after which they discovered that they had a bigger problem in the form of the weapon's guardian, the Earth Dragon. Kai happened to be holding the Scythe at the time and decided that the only way out was to use it, contrary to Master Wu's instructions. After escaping, Kai was strictly reprimanded by Master Wu, and they went onward toward the next weapon, the Shurikens of Ice.

King of Shadows

Kai, Nya, and Wu

While on their way to the Frozen Wasteland, the location of the Shurikens of Ice, Wu tells the Ninja about the most powerful technique in Spinjitzu, the Tornado of Creation. Kai began to attempt it but was stopped by Master Wu, who explained that it could lead to disastrous consequences if done incorrectly.

After they succeeded in finding the Shurikens, the Ninja ascended to the Floating Ruins for the Nunchucks of Lightning. After retrieving it, they used Jay's gliders to descend into the Forest of Tranquility, where they made camp. Kai was later awoken in the middle of the night and lured to the Fire Temple by Garmadon, who was pretending to be his sister. Kai was forced to remove the Sword of Fire from its pedestal to cut a chain and save his sister from falling. He was then attacked and defeated by his own shadow under Garmadon's manipulation, but Master Wu arrived before the dark lord could claim the sword. Realizing it had just been a trap to lure them away from the other Ninja, the three attempted to escape but were stopped by the Fire Dragon. As a last resort, Wu sacrificed himself and ventured into the Underworld with the Sword of Fire. While his act kept the four Golden Weapons apart, Kai and Nya were still left in the hands of the Fire Dragon.

Weapons of Destiny

DX Kai

Luckily the Fire Dragon soon realized that they were simply trying to protect the weapons, and by the time the other Ninja arrived, Kai and Nya had befriended the Dragon. They assembled the other guardian dragons and mounted them cross over into the Underworld.

Once there, the Ninja attempt to use the stalactites to sneak past the guards of the Skulkin fortress but accidentally grabbed onto the legs of a Spykor. Out of fear, Kai and the others fell to the ground outside the fortress where they were quickly surrounded by Skulkin and Spykors alike. With their options limited Jay suggested they perform the Tornado of Creation and the Ninja successfully performed the technique, turning the fortress into a Ferris Wheel prison. The Ninja descended into the throne room where Master Wu was dueling Samukai for the Golden Weapons. Kai forbade the other Ninja to interfere as it was their master's fight. Wu was quickly defeated, but when Samukai took the Sword of Fire, a portal between dimensions was formed, and Samukai was destroyed. This allowed Garmadon to escape from the Underworld.

Knowing that he would one day return, Kai took the Sword of Fire and vowed to protect it, as did the others with their respective weapons.

Celebrating their victory

Kai and the other Ninja returned to Four Weapons where they were reunited with Nya and assured the villagers they would be ready when Garmadon returned.


Flight of the Dragon Ninja

The Ninja are told to train by Master Wu but instead opted to spend their time racing their dragons. Jay won the race and began bragging about his skills. Kai and the others challenged him to another race over the forest and back, with the winner becoming "Dragon Master" for a month. Zane objected, feeling that the Ninja should be training, to which Kai replied that riding their dragons was a form of training.

The race begins, and Kai and Zane fly their dragons over the clouds, where they briefly dueled each other with their dragons' elemental breaths. On the home stretch, they were all neck-and-neck, but Cole won when he "activated the turbo"—a roasted chicken dangled in front of his dragon's nose. Once the others landed, Kai congratulated Cole on the win but said that they would get him the next day. Cole reminds the others that the winner was supposed to be "Dragon Master" for a month, and Kai and the others deny ever agreeing to the bet.

The New Masters of Spinjitzu

Kai sleeping with The Sword of Fire above his head

One night, Nuckal and Kruncha infiltrate the Monastery of Spinjitzu to steal the Golden Weapons from the Ninja while they sleep. Although the theft went off without a hitch, Kai was awoken when the Skulkin Generals lost control of the weapons and accidentally activated the training course. Half-asleep, Kai went outside to shut the course off, irritably reminding Jay that he had to repair whatever flaw was causing it to turn itself on. With that, Kai went back to sleep, completely unaware of Kruncha and Nuckal's presence in the monastery. They quickly return the Weapons to the Ninja with haste and return to the Underworld.

Return to the Fire Temple

Ninjago Return to the Fire Temple 41.png

While taking a ride on the Fire Dragon, Kai and Nya are suddenly taken to the Fire Temple. After dismounting the Dragon, Flame led Kai to a passage connecting Ninjago to the Underworld. Kai starts planning what to do when the ground falls out from beneath him. He finds that the Skulkin are assembling to reenter Ninjago, and gets caught in a fight. He fought back, but they picked him up, disarming him. Nya and Flame then shoot a blast of fire, which scares the Skulkin away and seals the passage to the Underworld.

Rise of the Snakes

Rise of the Snakes

With peace throughout Ninjago, Kai and the other Ninja fell out of training and instead spent their time playing video games. After a three hour marathon, they are interrupted by Wu who unplugs the TV. He encourages them not to put off tomorrow what could be done today, and to start training again to

prepare for his brother's return to Ninjago. Kai reminds his Master that if Garmadon is to show up, they have the Tornado of Creation. Wu sighs and tells him and the others that they have barely scratched the surface of unlocking their True Potentials. Cole turns the tv back on, and the Ninja continue playing.

At that moment, Nya rushes in, bringing word that Garmadon was spotted in Jamanakai Village. The out-of-shape Ninja rush out the door and down to the dragon pen where Kai mounted the Fire Dragon with the Nya's help.

Eager to get back into the fight, the Ninja race each other to Jamanakai Village. Upon arrival, Kai argues with Jay about who had arrived first. They were interrupted by the sound of evil laughter from the village, and they draw their weapons. They approach the village but are surprised to find that it was, in fact, Lloyd Garmadon, the dark lord's son, who was causing trouble. Lloyd threatens to release the serpentine, an ancient race of snakes that once ruled Ninjago unless they give him candy. The Ninja tie him to the top of a sign and embarrass him in front of the villagers as they mock him by eating candy.

Kai in Kendo suit

As they prepared to return to the monastery, Kai discovered a scroll in Wu's bag which he had taken by mistake. They read it and learn of the Prophecy of the Green Ninja. It is said that one Ninja will rise above the others and become the Green Ninja. The scroll is also inscribed with drawings that are identical to the four Ninja, with a fifth Ninja in the middle. Kai believed himself to be the Green Ninja, as did the others, so when they returned to the monastery, the four Spinjitzu masters challenged themselves to a tournament for the title. Kai faced off against Jay in the first round and won, thus moving on to the final round against Cole. However, the tournament ended when Kai lost control of the Sword of Fire and the Ninja were scolded by Master Wu.

Determined to be the Green Ninja, Kai and the others devoted themselves to training. They were soon ordered back to Jamanakai Village and find that Lloyd had unleashed the Hypnobrai tribe of Serpentine. Kai once again mounted the Fire Dragon and upon arriving at the village, met up with Nya. The Ninja find that the Hyprobrai have the ability to hypnotize their victims into doing their bidding, and were doing so to the villagers. After discovering they would need the anti-venom from the Snake General's staff to save the village, the Ninja split up and after a fight with the snakes, sent them retreating. After the villagers had been cured of their hypnotism, Kai presented Wu with the staff and apologized for their lazy behavior earlier. With a new threat now upon them, Kai and the others returned to the monastery determined to unlock the secrets of their Golden Weapons and to reach their True Potential.


In the days that followed, Kai devotes himself to training at the monastery. While he was practicing Spinjitzu, Zane iced the course over, causing Kai to slip. He complained about Zane's strange behavior to Jay and Cole, only to be approached by Master Wu who noted that brothers are often different. Kai remembers one night when he went into the kitchen for a midnight snack, only to find that Zane had consumed everything but the cheese. The Ninjas' conversation was interrupted by the arrival of the Mailman who had a fan letter for Kai, and other mail for Cole and Jay. They make note that nothing has come for Zane, and Zane reveals that he has been an orphan all his life.

That night, Kai and the others gathered in the dining room and were surprised to see Zane emerge from the kitchen wearing a pink apron. The Ninja laughed, and Zane failed to find it amusing. Cole dumps a plate of food on Kai's head and shortly after a food fight breaks out.

The next day, Zane tells the others that last night he followed a mysterious bird to Lloyd's treehouse fortress. Together, they head into the Forest of Tranquility and find it exactly where Zane said it would be.

Determined to destroy it before it becomes operational, Kai and the other Ninja snuck into it and destroyed its supports. They reached the last support, but Cole, who was hypnotized by a serpentine earlier, turns on them. Before long, Master Wu came riding in on Flame playing an ancient flute, which canceled the Serpentine's powers. The group returned to the Monastery on Flame and discovered the Serpentine had set fire to it in order to steal back their staff.

Kai watching the Monastery burning

Zane asked Shard to put the fire out but, the Monastery was beyond repair. Kai and the others verbally attacked Zane but Master Wu caught them reminding them that Zane was their teammate and had them apologize. Before they could, Zane flew off on Shard. Kai and the others assume that he was so hurt by their words that he ran away. Later on, the Ninja eat around a fire on a cliff, homeless, until Nya noticed Zane entering the camp. He reveals to them that he was not hurt by their words, but saw the falcon again, and followed it to an abandoned ship. He told them that was their new home, and he made them dinner.

Kai and the others joyfully run towards their new home, ready to eat Zane's home-cooked food.


After arriving on Destiny's Bounty they find that it is in disrepair. Master Wu makes the Ninja clean up their new home while he runs an errand with Nya, which they are reluctant to do.

They proceed in cleaning it up, dusting the sail, cleaning the cabins, and reworking the electronics. When finished, they put all the trash and junk in the bin outside.

Unlocking the Blade cycle

Later on, while the Ninja are relaxing, Jay's parents, Ed and Edna, arrive. They are given the tour of the Bounty by Jay, but he insists that they leave due to the threat of the Serpentine. While there, they reveal that Jay was born in a junkyard, a fact which Jay is embarrassed about. Eventually, his parents are reluctant to go but leave before dark. Before going they implore that Jay visits them sometime soon. Jay agrees, and they head out.

The next day as they are doing work on the brig, the other Ninja try to convince Jay to visit his parents. Although he is reluctant at first, he agrees to go. He goes to mount Wisp but finds that he has no interest in going anywhere. Master Wu tells the Ninja that their dragons are molting, and are to return to the Spirit Coves in order to reach maturity. The Ninja are disheartened, and Jay asks Nya to accompany him on the long walk. Kai and the others think he wants them all to go, and so the whole team accompanies him.

When the Ninja arrive, they find Jay's parents nowhere to be found, until they find them locked in an old refrigerator. They learn that another tribe of serpentine, the Fangpyre, had bitten Jay's parents and infected them with venom, slowly turning them into serpentine.

Kai and the other Ninja are ambushed by the Fangpyre, who, lead by Lloyd, have turned the whole junkyard into a snake infected area. Kai and the others defeat the snakes and attempt to escape. Master Wu tells them that they can get out of there faster by turning their Golden Weapons into vehicles. Kai turns his sword into a bike and drives away as the others do the same. They escape with Jay's parents after stealing the Snake General's staff, and return to the Bounty, and cure Ed and Edna with the anti-venom. The Bounty is rocked to the side by one of the Fangpyre helicopters, and they drop the staff, returning it to the serpentine and Lloyd.

Never Trust a Snake

Ninja in pajamas

Zane is woken up with a start one morning and recalls that he had a dream. Kai and the others ask him what it was about, and he tells them that he saw the Green Ninja. The Ninja implore him to elaborate, but Master Wu interrupts and reminds them that it is time for training.

On the deck, Wu teaches them different poses, all the while they are ignoring him to learn more about the dream. Wu catches them slacking off, and tells them that as punishment they must train all day and come up with the answer to a riddle, "What is the best way to defeat an enemy?" Kai fails to interpret the riddle along with the other Ninja, so Master Wu leaves them to train.

Zane finishes telling them about the dream, and Kai assumes himself to be the Green Ninja, due to his fists being aflame. The Ninja argue over who is the real green ninja and get back to training.

Later on, they find out that a boarding school has been attacked by Lloyd and an unknown Serpentine member, (who is later revealed to be Pythor.)

The Destiny's Bounty takes them there, where they drop through the roof of the building on an anchor. Kai and the others chase the panicking Lloyd through the building until they reach the roof. There, Pythor steals Lloyd's map of the Serpentine Tombs and disappears. The Ninja take Lloyd back to the Bounty and find that Master Wu is reading him a bedtime story.

They are confused as to why he is read a bedtime story after causing so much trouble, and Master Wu reveals the answer to the riddle- the best way to defeat your enemy, is to make him your friend.

Can of Worms

Kai discovers one day that all of his high scores have been replaced by Lloyd who at the time blamed it on Cole.

Lloyd screws with the other Ninjas' hobbies as well, ruining Jay's robot, Cole's chili, and turning Zane's gi pink, but he is eventually caught, and reprimanded by the Ninja. They try to snitch on him to Wu, but he reveals that he put Lloyd up to it to teach the Ninja "the destructive power of rumors."

After this turn of events, Nya reveals that she has located the Constrictai and Venomari serpentine tombs. Kai and Jay take the Venomari tomb while Zane and Cole take the Constrictai tomb.

Kai hallucinating

They arrive in the Toxic Bogs and find that the tomb has already been opened. They soon find that they are being ambushed. Kai is intoxicated with Venomari venom and begins to see elves and gingerbread men attacking him. Jay attempts to protect him while Kai is trembling from the visions. Cole and Zane arrive but are followed by Pythor and the Constrictai. As the two tribes surround them, the Ninja believe they will not survive the next attack.

Kai hallucinates that a rope is in front of him, only for an actual rope to appear moments later. Suddenly, a mysterious Samurai in a massive robotic mech appears and scares away the Serpentine. The Samurai saves the Ninja but knocks them unconscious. They are soon saved by Wu in the Bounty.

Back on the ship, the Ninja are eating dinner (while Kai is still intoxicated,) while telling Lloyd and the others about the mysterious samurai. Kai insists that he had weapons coming out from every part of him, but the Ninja remind the others that he was sprayed with the Venomari venom.

They get an alert later on that the Serpentine have been spotted in Ninjago City, and the Ninja quickly ascend there, expecting to find a massive serpentine gathering in the streets (at this point Kai's intoxication wears off.) They find that the Serpentine have gathered underneath the city, and venture below.

They find Pythor giving a speech to the serpentine tribes, attempting to unite them. The Ninja know this is a bad sign, so they use the destructive power of rumors to try and ruin his assembly. They are eventually caught and are chased throughout the sewers. Kai, Cole, and Jay are quickly captured, and Zane is left trying to escape from them.

After using his pink gi to distract the snakes, he breaks out Kai and the others and they escape, having ruined Pythor's plans.

Later on, back on the Bounty, Lloyd apologizes for messing with the Ninja's things and reveals that he has cleaned Zane's gi.

The Snake King

The Ninja are eating breakfast talking about the Samurai when Kai offers the other Ninja a bet: whoever finds the identity of Samurai X, they are the best and the Green Ninja.

Ninja ready to fight

The Ninja agree to the terms and are interrupted by the arrival of the mailman, who has brought them their new Ninja suits. As they are checking the new merchandise, they get an alert that some snakes were spotted at Mega Monster Amusement Park. They put on their new suits, and arrive at the park to find that the serpentine have already been apprehended by the Samurai.

The Ninja make it their mission to catch this samurai, and they split up separately to do so. Kai attempts to capture him when he finds him in the Wildwood Forest but he quickly captures Kai in a net.

Later, when it's his turn to look after Lloyd, he drops him off at an arcade, then leaves, hoping to find the Samurai. After finding Lloyd missing, the Ninja go looking for him at the Lost City of Ouroboros.

The Ninja get trapped in a cage that Pythor set up knowing they would come, and steals their golden weapons. He forces them to battle the Samurai X to entertain the other Serpentine, and they find out that they are no match for him.

In a strange turn of events, the Samurai helps them escape while stealing back their Golden Weapons.

The Ninja and Samurai X crash land somewhere nearby and are left scattered. Kai regroups himself and finds that he landed near the Samurai. He walks up to him and finds that their secret identity was none other than his sister the whole time! Nya implores him that he doesn't tell the others her secret, to which he tells her about the bet he made with them.

He sees what this means to her, and agrees to keep quiet. Nya gives him back the Golden Weapons, and he and the Ninja return home separately than Nya.

Back at the Bounty, the others interrogate Kai about the encounter he had with the Samurai. Stumbling over her pronouns, he tells them that she- he, just handed him the Golden Weapons and left, which was a lie. The Ninja have a hard time believing this but carry on their meal.

Tick Tock

As the Ninja continued to train, they became capable of impressive feats; Kai was able to run across a long path of red-hot coals with no ill effects. Later, he timed Zane as he sat underwater, expressing bewilderment as his white-clad ally remained beneath the waves for over ten minutes. After Zane finally returned to the ship, Kai and the others began speculating whether they had reached their full potential, and decided to ask Master Wu before they jumped to conclusions.

When Kai and the others found Master Wu, he was packing his things, seemingly in preparation for a journey. Kai presented the Ninjas' question, but Wu quickly shut down the notion. He tells them that when they find the key, they will know.

They change the topic, and ask their Master about the katana he is holding, and he tells them the story.

When Wu and Garmadon were young they were the best of friends. One day while they were playing sword fighting in the monastery, Wu's blade was knocked over the fence. Fearing that their father would be mad, Wu refused to go and retrieve it. His brother reminds him not to put off until tomorrow what can be done today, and goes after it himself.

Garmadon hops the wall, and reaches for the blade, only to be bitten by a snake. He falls ill, and Wu reminds the others that that snake was the Great Devourer, the same snake that Pythor wants to resurrect. . . Its venom turned his brother into the Dark Lord.

After his story, he says that he is leaving to find someone who can be of aid in finding Lloyd.

Later, Kai and the others put posters up to find the Fangblades, which Pythor needs to resurrect the Devourer. Zane stops putting up the flyers and notices the Falcon. The others remark that whenever they follow it, it brings them good fortune, so they chase after it. They follow it through Ninjago, hoping it will lead them to a Fangblade.

Exhausted Kai

After chasing it for miles, Kai and the others begin succumbing to exhaustion, telling Zane to continue following the Falcon into a snowy woodland.

The Ninja eventually pick themselves up and find Zane to be horrified by something he's uncovered in an old workshop; Zane is an android. Kai and the others still accept him and don't seem bothered by the revelation, they even think it's pretty cool (with Jay referring to Zane as a "Nindroid.")

The other Ninja leave Zane to think and immerse back outside. Creatures referred to as Treehorns attack them, and they are quickly defeated by them. Zane returns and finds his friends in trouble, and helps fight back.

The queen treehorn emerges, but using his newfound powers, Zane freezes the Queen as the other Treehorns retreat. While the other Ninja are happy for Zane for being the first to unlock his True Potential, Zane proclaims with confidence that they are going to find Pythor.

Once Bitten, Twice Shy

While watching Nya explain the venom process of a Fangpyre, Jay tries to impress her with men's cologne but finds out that Kai and the others pranked him by giving Jay perfume, which Nya is allergic to.

Later on, the Ninja find that a Fangblade is at Mega Monster Amusement Park, and prepare to go there to acquire it. Jay attempts to go on a date with Nya at the park but Kai warns him not to, telling him "to get his priorities straight."

Kai and Cole

The Ninja discover a ride that has Serpentine activity near it. The Ninja discover the Serpentine excavating the Fangblade and Kai declares a fight. Kai gains the upper hand in the fight along with the others but a mistake on Zane's part causes them to get frozen from one of his attacks. Kai and the others escape their confinement and Jay is revealed to have gained his True Potential while Nya is discovered by all the other Ninja to be Samurai X.

Kai brags that he is the first to have found out and therefore should be the Green Ninja, but the other Ninja claim to not remember ever discussing that.

The Royal Blacksmiths

The Ninja, upset at losing the Fangblade, brainstorm for where the next Fangblade would be. Cole brings up that he knew about a trophy called the Blade Cup that seemed to be a Fangblade that his father once won at a talent show.

The Ninja go to Cole's father and disguise themselves as dancers as to not cause suspicion around Cole's dad, who is unaware of Cole being a Ninja.


They discover the Blade Cup is located at a talent show and enter it as a cover to steal it. Lou trains Kai and the others to dance, however, the Serpentine have also discovered the Fangblade's location and disguise themselves as people in the audience, judges, and performers.

The Ninja are preparing inside the backstage of Concert Hall. However, Jay and Kai begin arguing when they continuously mess up the routine. Cole interrupts by saying that they will be leaving soon after their theft, Jay replying that they should try to win it. Having overheard the conversation, Lou confronts them about it. Cole takes the opportunity to explain to him the situation of having lied to his father for many years, revealing that he is a Ninja. He informs Lou that if they do not steal it themselves, the Serpentine will instead. Regardless, Lou is unaccepting of his son for wanting to steal the prize, storming out of the room. While the Ninja comfort Cole, a group of disguised Serpentine called the Treble Makers appear backstage. Kai hears Pythor's voice from the crowd, peering out from behind the curtains to see the General among the judges.

The other judges say that Pythor looks nothing like how he did in the photo, Pythor coming up with an excuse before the voice of the former judge alerts the others of his situation from Pythor's stomach. The other judges gaze in disbelief, Pythor quickly persuading the noisy judge to quiet down.

Kai tells the Ninja of the Serpentine, and when Jay finally agrees to steal the Blade Cup, Cole instead decides that they will win it.

The Treble Makers sing on stage, the crowd booing as Pythor gives the performance a perfect ten. The other judges each give it a six, but Pythor intimidates them into flipping their scorecards.

The Ninja are called up on stage, though as they linger backstage, Zane confesses to having butterflies in his stomach. They then share a few encouraging words among themselves, going on stage by the name of Spin Harmony. As they dance in perfect sync, Skales orders the Hypnobrai to attack. However, the attack only intensifies their performance, the Ninja incorporating defending themselves in their routine. When the Fangpyre join the ambush, Cole then uses the opportunity to perform the Triple Tiger Sashay with success.

The Ninja win the talent show and Cole's father is proud that they won the trophy without cheating as the Serpentine tried to do. Pythor then attacks and nearly kills Cole's father, but Cole protects him and gains his True Potential while the Serpentine manage to steal the Fangblade, making Kai the only Ninja left to find his True Potential.

The Green Ninja

Master Wu finally returns and surprises them by bringing Lord Garmadon, who has now grown four arms.

Kai attacks Garmadon, assuming the worst, but Master Wu reveals that he is helping them search for Lloyd and orders the Ninja to respect him during their temporary alliance.

Kai gets more skeptical about Lord Garmadon and at one point overhears a conversation about the Green Ninja between Nya and Master Wu. Lord Garmadon discovers Kai eavesdropping and the two fight, only to be broken up by Nya and Master Wu.

Later on, Kai searches for the Golden Weapons and discovers Garmadon is holding them. Thinking he is stealing them, Kai battles Garmadon and "wins." He expects to have unlocked his true potential, however, Garmadon reveals that he allowed himself to be defeated, as he was only fetching the weapons for the Ninja since they were heading over to their destination; this was confirmed when Master Wu told Kai that he was the one who told Garmadon to fetch them. Realizing this, the other Ninja scold Kai for his foolishness, leaving him humiliated. Despite the situation taken care of, Kai still retains his suspicion towards Garmadon.

After discovering the next Fangblade is located at the Fire Temple, the Destiny's Bounty arrives there and the group travels inside. They watch as the Serpentine dig for the Fangblade, Jay quickly pointing out Lloyd's location in a cage. Rattla uncovers the Fangpyre Fangblade, much to Pythor's pleasure. While Pythor gleefully gazes at the Fangblade, he notices the Ninja in the reflection and orders the tribes to attack.

The Ninja quickly fend them off, though as Pythor leaves the Temple, he commands Bytar and Chokun to drill holes in the walls to allow the rising lava to quicken. Jay announces that they must leave as the Temple is becoming unstable, but Lord Garmadon runs after the Serpentine in an attempt to retrieve his son. Seeing that Lloyd is causing the trouble, Pythor orders the Serpentine to get rid of the caged boy by dropping him to the landing below. Lord Garmadon continues to fight the Serpentine to get the cage, finally reaching it and pulling up his son before his cage could fully melt in the lava.

Kai then rushes up the steps in order to obtain the Fangblade, flinging the Sword of Fire at the Fangblade to impales it in the wall. A furious Pythor attempts to pull it out, but Skales alerts him that they must leave at once, Pythor complying as the lava shoots up at them. Everyone except for Kai meets up at the exit and Lloyd calls out to his missing teammate as Kai makes his way to the Fangblade. However, the ground beneath Lloyd breaks loose, causing him to fall down to the lava below. The group watches in horror as Lloyd stands on the sinking piece of land.

Meanwhile, Kai finally pulls his sword out of the wall, but the Fangblade falls down below, landing just above the lava. Kai tries to grab it but chooses to save Lloyd instead when the latter cries out for help. He grabs Lloyd and tries to escape, but they become surrounded by lava spewing into the air.

Unlocking his True Potential

Everyone else reaches the Destiny's Bounty, the entire team distressed as they see lava exploding out of the volcano. In the middle of their remorse, they suddenly see a fireball appear from the volcano, which floats toward the Destiny's Bounty to reveal Kai and Lloyd inside. Having unlocked his True Potential, Kai stands proudly, only to fall to the ground in exhaustion.

The Ninja cheered for Kai; even Garmadon genuinely thanks him for saving Lloyd. Kai then admits that the reason why he unlocked his True Potential: he had a realization after reflecting of his failed intent to get the Fangblade (which later ends up being found by Pythor), he realized that his true destiny was not to become the Green Ninja, but to protect Lloyd, who is revealed as the true Green Ninja; this was confirmed when the Golden Weapons levitated in a green light next to Lloyd's presence. Realizing this, Wu finally realizes that Kai and the rest of the Ninja are tasked to train Lloyd to become the Green Ninja, but is very saddened by the fact that Lloyd and Lord Garmadon will have to face each other in the future for the sake of Ninjago, something which both a horrified Garmadon and Lloyd didn't expect. Upon realizing this, Kai expresses an empathetic face, seeing how complicated it would be for Lord Garmadon and his son to be fighting each other due to their relationship.

All of Nothing

The Ninja find and corner Spitta and force him to give them information on Pythor's whereabouts. Spitta tells them that they are days behind him, as he is already on the way to the next fangblade.

Back aboard Bounty, Lloyd suggests that while Pythor is away, they should go to the Serpentine's inner sanctum to retrieve the other three Fangblades. The Ninja quickly find the snakes inner sanctum hidden inside the Constrictai Tomb, and Lloyd and Lord Garmadon stay behind.

Inside the tomb, the Ninja attempt to defeat the snakes, but to no avail. The Ninja are quickly captured and are forced to contact Lloyd for help.

Kai and Pythor

Lloyd and Garmadon get into an argument, resulting in Garmadon leaving without telling where he is going. Lloyd then gets a message from Nya asking for reinforcements, and Lloyd finally goes on his first mission as the Green Ninja.

Meanwhile, Kai and the others attempt to escape but are quickly recaptured by Pythor who now has all four Fangblades.

The Serpentine want to celebrate with a Slither Pit tournament, which Pythor agrees to. Lloyd arrives but comically falls down right in front of Pythor. Just before he is captured, however, Garmadon arrives with the Skeleton Army. Lloyd frees the Ninja from their cage, and together they steal the four Fangblades and go back to Destiny's Bounty where Lord Garmadon leaves, making Lloyd upset.

The Ninja are having a party for Lloyd getting the Fangblades, but little do they know that Pythor is outside their very window, plotting revenge.

The Rise of the Great Devourer

Unaware that Pythor has snuck aboard the Destiny's Bounty, the Ninja plan to throw the Fangblades into Torchfire Mountain. This fails when Pythor reveals his location to them, and steals the fangblades back, knocking Master Wu off the deck and clinging to the side. Kai and the others just barely save him and find that Pythor has escaped on a Rattlecopter with the Fangblades and takes control over a tour bus.

The Ninja intervene, and Kai fights off Serpentine on the top of the bus and is nearly knocked onto the road. Eventually, Master Wu detaches the engine from the rest of the train and confronts Pythor, much to Kai's dismay.

The bus crashes into the Lost City of Ouroboros, halting the Ninjas' transportation. Fortunately, Lloyd arrives and takes them aboard the Destiny's Bounty. Just as Kai and the others attempt to save Master Wu, Pythor unleashes the Great Devourer.

Day of the Great Devourer

After watching Wu and Pythor get eaten by the Devourer, Kai quickly leads the Ninja and the others back to the Destiny's Bounty. The Devourer chases them down, and the Ninja do all they can to ensure their escape. Unfortunately, the massive snake gets too fast, and they are forced to evacuate the Bounty.

The Ninja are forced to watch as the devourer, in one big bite, crushes the entire ship, and they run away.

Kai mentioning Wu

As Jay begins to admit defeat, Kai inspires the team with some words of wisdom from Wu.

The team then heads to Ed and Edna's junkyard on their vehicles. It is there that Kai reveals the blueprints for the Ultra Sonic Raider. While there they discover that the Great Devourer has followed them, they use the Tornado of Creation to build the Raider out of all the scrap at the junkyard to defend themselves against it. In the battle, Kai discovers the Devourer has a weak spot on its forehead. The Ninja manage to drive it away from the area but Zane is injured during the conflict.

Realizing the serpent is heading to Ninjago City, Kai and the others follow it to its destination. While the creature begins destroying the city, the Ninja arrive and attack it. The fight is interrupted by the Ninja's Dragons returning as the Ultra Dragon.

Kai and the others cheer their respective Dragon on until the Devourer gains the upper hand and knocks it into a building. Lord Garmadon arrives and alerts the Ninja that the only way to truly destroy the Devourer is with the Golden Weapons, and he is the only one that is able to possess all four.

Kai is reluctant to hand him the weapons but eventually agrees. Kai and the others lead the snake around the city, eventually trapping it biting its own tail. The Ninja watch as Garmadon jumps from a building and strikes the creature's head with the weapons, causing it to explode into a mass of green goo.

Kai is annoyed when the Golden Weapons are nowhere to be seen, but rejoices when he discovers that Master Wu is alive. Victorious, the Ninja celebrate and are preparing to help Lloyd reach his full potential.

Legacy of the Green Ninja

Darkness Shall Rise

Kai working as a party entertainer

In the aftermath of the Great Devourer's defeat, Kai and his friends spent much time cleaning up the great serpent's venom from around the city.

As the Ninja adjust to their reduced powers (thanks to the loss of their Golden Weapons), their thoughts turned to finding a new home and training Lloyd for the inevitable battle with Lord Garmadon. They met with a realtor, and she suggested they train Lloyd in the Ninja Suite, but Kai scoffed at the expense.

Deciding that they needed to live in comfort before they could properly train Lloyd, the Ninja opted for a lavish suite and took up jobs around the city to pay for the rent, with Kai taking up a job as an entertainer at children's parties.

Being occupied by their new jobs, the Ninja had limited time to train Lloyd, due to being too tired once they got back from work.

One day, the Serpentine suddenly rob a bank, and Kai, who was entertaining nearby, ran off the job to get there, resulting in him getting fired. Kai and Zane meet Cole there, who is in the middle of being fired as a security guard when they remember that they heard that the snakes were taking the subway.

They make their way down there and hop onto an oncoming train that is occupied by the snakes. They enter the train, and fight with the snakes as best they can without their powers. Eventually, they find that Jay is walking, albeit tied up, along the rails. They stop the train in time to save him but allow the Serpentine to retreat.

The Ninja return to their home and find Lloyd missing. They realize that they should never have left Lloyd, and should never have taken those jobs. At that moment, Wu, Nya, and Lloyd arrive. Lloyd reveals that he wouldn't be okay if Sensei hadn't saved him.

Dissatisfied with their jobs, they move into a smaller, dinkier apartment where they will be able to train Lloyd without any distractions.

Pirates vs. Ninja

Kai and Jay dressed up as pirates

Kai and the other Ninja began to properly train Lloyd, though soon realized their apartment wasn't the most suitable place. Wu sent them out into the city to look for a better training ground and they soon found Grand Sensei Dareth's Mojo Dojo. There they asked the owner Dareth if they could share the space to which he agreed if one of them could best him in a fight. While Dareth was showing off all his animal styles, Kai used Spinjitzu to send him to the ground, thus winning the fight.

Following their first session of training Lloyd in the dojo, the Ninja left the dojo to find the city under attack by Captain Soto's pirates. The Ninja quickly boarded a bus and raced towards the boat. After stopping by Wong's Costume to disguise themselves as pirates, Kai and the others boarded the ship and confronted Soto's crew. After a brief fight and with the help of the Ninja, the pirates were eventually subdued.

Double Trouble

Ninja fighting with Bizarro Ninja

Jay assisted in helping Lloyd use his Green Ninja power to light a light bulb at Dareth's Mojo Dojo. Despite the Ninjas' encouragement, Lloyd fails to light a light bulb and became mad. Just then, Nya rushed into the room carrying a letter stating that Lloyd's old school, Darkley's School for Bad Boys, has changed to Darkley's School for Great Children and that they wanted to Lloyd to receive an honorary award of excellence.

Kai and the others flew on the Ultra Dragon to the school where they are locked inside a room and discover that the students there had set it all up to get revenge on Lloyd. After very careful thinking, Kai and the Ninja escaped the 'prison' only to find that Garmadon had created evil duplicates of the Ninja, who had infiltrated the school and were attacking the students. The Ninja could not let the evil Ninja hurt anyone, so they attacked their evil counterparts. They would have been defeated if it weren't for the students coming to the rescue and confusing the evil Ninja, who let their guard down and were defeated.

Ninjaball Run

Ninja winning the race

Kai, along with the other Ninja, competes in the Ninjaball Run to win the prize of $100,000 in order to save Dareth's Mojo Dojo. The Ninja race in the Ultra Sonic Raider. Lloyd flies on the Ultra Dragon so that they have a better chance of winning the race. They race through dangerous terrain, and eventually Lloyd and his dragon crash putting him out of the race.

Even though the Ninja struggled to maintain a lead, especially when Garmadon enters the race. But thanks to a lever installed giving the Ultra Sonic Raider flight, and a piece of Ed and Edna's car Jay took after they crashed, the Ninja win the race and claim back the Destiny's Bounty in the process!

Child's Play

As a child

As the Ninja are trying to train Lloyd, they find out that he was anticipating to get the new issue of the "Starfarer" comic. Nya then came in to tell them to stop Garmadon, who broke into the Museum. After stopping them from reviving the Grundle, they realized they were turned into kids. When noting the Serpentine is stealing a sarcophagus, they chased them but noticed they're kids and that Garmadon's Mega Weapon did work. Eventually, the police came and accused them of stealing.

The Curator forgave them, asked what happened to the Grundal bones, which was missing. They explained it's been revived, but they didn't believe them, prompting them to escape by disguising themselves. They called Lloyd to meet them at Buddy's Pizza with their weapons. Lloyd then tells them he knows who can help them.

They went into a comic book store, where Lloyd introduces them to Rufus McCallister. Rufus explained weapons are no use against the Grundal and that light, such as from an illumisword, can defeat it. After hearing they must be won, the Ninja motivated Lloyd to enter.

Lloyd, however, lost just before the Grundal came. They tried to get the door opened, but it's jammed. They grabbed the illumiswords, but they easily broke. Wu gave them the Tomorrow's Tea but hesitated to turn Lloyd into a teen. Lloyd threw the tea for them, ultimately defeating the Grundal

Wrong Place, Wrong Time

Two Kais fighting together

Lord Garmadon uses the Mega Weapon to go back in time and make it so that Lloyd would never become the green Ninja. The Ninja later figure out his plan and jump into the portal Garmadon had previously created. They find themselves in Ignacia, at the time Wu came to Kai's shop and even before Skulkins attacked the land. They catch old Wu and explained to him about the situation. This time, skeletons didn't kidnap Nya, and Kai from the past had no will to become a Ninja. Wu then leads him and Nya to the monastery. The Ninja decided to dress like skeletons and kidnap Nya so past Kai can get a reason to become the Ninja. They did that, and Garmadon took Nya to the Fire Temple. Present Kai reveals himself to his past self, and they work together to defeat Garmadon. They succeed by destroying the Mega Weapon and Kai, along with other Ninja, comes back safely.

The Stone Army

Kai with his sword broken

After the Ninja reluctantly woke up for sunrise exercises, Wu told them they have to clean up the Ultra Dragon. They left Lloyd to do the job alone, but after he said it's not fair, they played a round of Rock, Paper, Clamp, with Lloyd losing. Before he started cleaning, he informed them that he lived at Darkley's School most of his life and that he doesn't remember his mother. Nya came along and told them the Museum needs their assistance.

The museum's curator showed them to the gift shop and said the Great Devourer's venom bought the Stone Warrior merchandise to life. The Ninja tried to keep it under control but wrecked the place in the process. When the Ninja met up with Wu, he introduced them to Misako, Lloyd's mother. When Misako tries to explain to Lloyd why she abandoned him, the Ninja watched him as he walked away.

After finding Misako and Lloyd at the Bottomless Pit exhibit, Misako explained to them about the Overlord. When the Giant Stone Warrior burst in, Kai was told to defeat it, but his katana broke and was thrown into a large vase. They eventually ran from the Warrior. Lloyd told them to distract him, to which Kai and the others agreed. They did just that, but have to run away after it broke free.

The Day Ninjago Stood Still

The Ninja, Dareth, and Gayle Gossip

Kai helped train Lloyd to fight without using his eyes in Dareth's dojo, but they were soon interrupted by a series of earthquakes. They halted their training to tune into the news and learned that the aftershocks were getting worse. Kai immediately blamed Garmadon, though Misako pointed out that the Dark Lord would never do anything to harm his son.

The Ninja began to patrol the city for danger and even save a woman who was trapped by the collapsing street. The city soon falls under attack by the Stone Army and Master Wu orders the Ninja to send everyone to the NGTV office tower where they can be evacuated by the Destiny's Bounty. The citizens all climb to the roof while the Ninja hold off the Stone Warriors using the Ultra Sonic Raider and the Ultra Dragon. Kai continues to help hold off the Stone Army.

The Last Voyage

Kai, Dareth, and Nya

The Ninja sail to the Dark Island on the flightless Destiny's Bounty. Along the way, they run into a storm and the ship-eating Starteeth. When the storm passes the ship, which now is missing a rudder and has a hole in the side, the ship runs ashore on an island with a prison tower. After Dr. Julien told him the Skulklin trapped him there, he agreed to help fix the Bounty. The Ninja and Dr. Julien left the prison and continued their journey to the Dark Island.

Island of Darkness

The Ninja finally arrive on the Island of Darkness, where the Stone Army is preparing for the final battle. The Ninja learn that the Temple of Light is where they can receive their elemental powers. In order to do this, the Ninja must use a medallion to find the temple. Later Jay was able to find the Temple of Light by aligning three lights with the holes in the medallion—the temple is at the top of the island's highest mountain.

In the Temple of Light

With their new vehicles, the Ninja head for the Temple of Light, barely keeping ahead of the Stone Army. Inside the Temple, they find pictures on the walls depicting their journey from the past until the present. Further in is a great bell, hanging above a strange design on the floor bearing the Ninja's symbols. Realizing that it's the Instrument of Peace, Lloyd strikes it, causing a light to shine on him and beams of energy to reflect off crystals in the walls. Soon, the entire room is crisscrossed with beams, and one hits a pillar, making it glow brightly. At the foot of the pillar, Kai's armor transforms, and an Elemental Blade with the power of Fire appears in his hand as well as the other Ninja. As their swords manifest blades representing their respective elements, Lloyd rises into the air. The Ninja use their swords to send their elemental powers to Lloyd.

The Stone Army finally marches into the Temple, but the Ninja are more than ready for them—using their new elemental powers, they easily trounce the warriors. Kai beats up some soldiers within a ring of fire. Finally, Lloyd summons the power of the Golden Dragon, creating a brilliant light that frightens the remaining stone soldiers into retreat.

The Last Hope

The Ninja on the beach.

At the beach, Dr. Julien repairs the Falcon, while the Ninja celebrate their restored powers by shooting down coconuts. The party is interrupted by Master Wu, who chastises the Ninja for their unseemly mirth; they may have the power to defeat the Stone Army, but the Celestial Clock is still counting down to the final battle between light and darkness. At that, Misako reveals a way to at least delay the battle: if the Helmet of Shadows is returned to its pedestal, the countdown might stop long enough for them to gain an advantage. Risking everything, the Ninja disguise themselves as Stone Warriors and escort Misako to Lord Garmadon's camp. As General Kozu takes Misako to his master's tent, the disguised Ninja are put to work carrying Dark Matter to the super-weapon. The weapon is surrounded by a wooden wall, but the Ninja notice one protruding detail—a very large cannon—and ponder what Garmadon plans to attack with it. Later the Ninja are, forcing them to fight their way back down to the entrance as Misako rejoins them.

The Ninja make their escape with Misako and Nya in the power drill, but the Stone Army pursues them until the Overlord reminds Lord Garmadon that the Ninja could turn the army against him if they don the Helmet. After a frantic chase that ends in the Power Drill being disabled momentarily, Garmadon goes for the kill, only for Lloyd to blast it with his powers. Lord Garmadon emerges from the wreckage, weakened and vulnerable; from the Power Drill, the Ninja encourage Lloyd to finish him off. Despite everything at stake, the Green Ninja is unable to strike the fatal blow, forcing him to jump aboard the Power Drill as the Ninja make their escape from the advancing Stone Army.

At the Celestial Clock, the Ninja meet with Master Wu and desperately look for the Helmet's pedestal with minutes to spare. As the Stone Army arrives, the Ninja find the pedestal and replace the Helmet, but it's one second too late; the countdown has ended and the final battle is upon them. As the clock fires a mighty energy flare inland, the Stone Army captures Nya and the Ninja are sent down into a crevasse. Surviving the fall, the Ninja head off to prepare for the final battle.

Return of the Overlord


Kai returned with the other Ninja to the beach where the Bounty was hidden and met up with Dr. Julien. As Wu and Misako attempted to raise Lloyd's spirits to face his father in the final battle, Kai pledged his fire to the Green Ninja and prepared for battle.

The heroes set off to Garmadon's camp, intending to begin the final battle, but were surprised to find it deserted upon arrival. Misako quickly realized that the Stone Army intended to use the ultimate weapon on Ninjago to shift the balance and allow the Overlord to cross over, thus the Ninja followed the machine's tracks in the hopes of stopping it before it was fired.

As the Ninja ran, they recalled memories of their past adventures until they were ambushed by Nya, who had been turned evil by Garmadon's Dark Matter. Kai urged Wu, Misako, and Lloyd to continue on ahead while he and the other Ninja fended Nya off.

While at first having a hard time stopping for fear of injuring his sister, Kai quickly realized a way to trap Nya using their Elemental Powers, and before long they were on their way again.

The Ninja arrived at the beach in time to witness the Overlord take control of Garmadon's body, having fired enough Dark Matter into Ninjago to allow him to cross over. Reassuring Lloyd that they stood behind him, Kai and the other Ninja raced into battle to defeat the Stone Army. Kai used his Elemental Blade to cut one of the Stone Army's machines in half before commandeering one of Garmatron's cannons. As Lloyd faced the Overlord, Kai watched with the other Ninja as their comrade was defeated. The Overlord proceeded to open a portal to Ninjago, though it closed just as the Red Ninja attempted to pass through it.

Rise of the Spinjitzu Master

Hitching a ride on Kai's Fire Robot, the Ninja returned to the Temple of Light, where they activated a hidden mechanism that revealed the Golden Mech. When Lloyd sat in the cockpit, his powers as the Chosen One restored the ancient machine to fighting form. With the Ultra Dragon's arrival to the Island of Darkness, the group was able to return to Ninjago City, only to find it infected with Dark Matter and ruled by the Overlord, now restored to his monstrous true form. Despite their fighting prowess, the heroes were almost overwhelmed by the Stone Army, only to be saved when Dareth donned the Helmet of Shadows and took command of the ancient soldiers.


Kai and the other Ninja proceeded to ascend the tower but only to watch them fall victim to the Overlord's corruption. Later he distracts Nya and Lloyd was forced to limp up to the top of the tower alone, where the Overlord was waiting. In the aftermath of the Overlord's defeat, all of his creations and corruption vanished. Kai reunited with his sister and allies in the crater left by the Garmatron's disappearance; he is even surprised to see that Garmadon has been transformed back to his good self thanks to Lloyd's victory over the Overlord. Watching Garmadon reunite with Misako and Lloyd, Kai shoots down Jay's intent of dogpiling the family by suggesting that they let them walk away to a peaceful moment.


The Surge

Kai and Cyrus Borg

Following the defeat of the Overlord, Ninjago entered an era of peace. Without an enemy to fight, the Ninja were no longer needed and thus began teaching at Master Wu's Academy. At one point, Kai was caught on video by Jay singing in the shower.

During a break on a rather stressful day, Nya approached Kai and the other Ninja and informed them they had received clearance for a field trip to Borg Industries. This didn't interest the Red Ninja who believed people should be learning from the past instead of wasting time on new technology, though he boarded the bus anyway.

Upon arriving at Borg Tower, Kai became stuck between the automatic doors, freeing himself just in time to board the elevator with the other Ninja as Cyrus Borg had requested to see them personally. After being introduced to the inventor, Kai questioned why the tower had been built atop where the Overlord had been defeated. Borg then presented them with a statue of himself as a gift for the Ninja, but promptly pulled Kai aside and ordered the Red Ninja to protect "them" with his life.

As the Ninja left with the statue, they accidentally dropped it and discovered new gis and the Techno Blades inside. Suddenly a robotic security voice in the elevator says that they should drop the blades. The Ninja refused, and the elevator drops toward the ground at high speed. The Ninja luckily escape into an elevator going up right next to it and manage to get their new outfits on for battle in their escape from Borg Tower.

When they get down of the tower, Master Wu takes the Techno Blades and says that he wants Kai and Zane in the air. Kai jumps on Zane's copter and hacks an enemy airplane, making it the Kai Fighter and reaching the outer space. While he was flying, Cyrus Borg gives him a visual message saying that a few weeks ago they discovered that new virus, Digital Overlord, in the industries' system. He also says that they have to bring the Techno Blades out of the city because if he finds out that they have them, he will never let them leave. After that, Kai gets into the sky fight with virus controlled planes. At the moment they almost get destructed, Lloyd comes on the Golden Dragon, defeating the robots. As the Ninja get back into the vehicles and get on the road outside of the city, Overlord spots that Wu is getting away with the Techno Blades so he sends two copters that capture him on the building roof. However before that happened, Wu quickly dropped Techno Blades into Kai's Fighter so the Ninjas could safely get them out of the city, while Wu gets captured by Overlord's forces.

The Art of the Silent Fist

Kai with his Techno Blade

After escaping from New Ninjago City, the Ninja hide their vehicles. Misako then greets them and shows them to the Monastery, but Zane offers to stay behind with the Techno Blades, as Garmadon (who is now "Master Garmadon,") forbids any weapons in his monastery. As night falls, Garmadon arrives and teaches the Ninja and his students about "the art of the silent fist." While everyone inside is practicing the technique, Zane catches P.I.X.A.L. and ties her up, then returns to the monastery as the Ninja come out to see what is going on. Zane then uses his Techno Blade to hack P.I.X.A.L.'s systems, freeing her from the Overlord's control. Grateful to Zane for saving her, P.I.X.A.L. tells the Ninja of Master Wu.

Suddenly, P.I.X.A.L. realizes she did not come alone and Nindroids surround the place. The Ninja successfully defeat the Nindroids by trapping them into a mill wheel which then rolls out. However, General Cryptor destroys the Ninja's vehicles. After that, the Ninja decides to split. Jay, Zane, Cole, Kai, and Nya gets an idea to shut down the power in the city to stop virus controlling machines in the land. As night falls, they arrive at the station, but with a high guard of Nindroids. They manage to get inside but can't find a way to break the power charge. When Cryptor sends Nindroids inside, Kai remembers Garmadon's lesson of fighting without fighting so they decide to lure Nindroids to destroy the charge which then explodes and all the power disappears, including P.I.X.A.L. who gets shut down


The Ninja have gone to Ed & Edna's Scrap N Junk to look for parts that would enable Zane's hover-copter to run on solar power. While Ed, Jay, Cole, and Kai search through the junk piles, Nya transfers half of Zane's power source to P.I.X.A.L. Unbeknownst to the Ninja, Techno Wu arrives via hover-copter and powers Cryptor, along with a few Nindroid Warriors, using electrocobrai. After activating a few Nindroids, Min-Droid sneaks and gets access to Ed & Edna's crane. The tiny droid uses the crane and launches the truck at a garbage pile.

Kai fighting with Techno Wu

Kai realizes and quickly informs his friends; the Ninja perform Spinjitzu and get out of the fallen vehicle, while Ed and Edna escape using bubble jet-packs. Meanwhile, Jay and Cole are captured, Kai battles Wu clanging their weapons against one another. Eventually Wu manages to fling Kai away. Nya frees Jay and Cole and they assist Kai. However, Wu traps the Ninja in a corner, but Zane and P.I.X.A.L. come with a magnified vehicle and pick up Wu since he is now part metal. The Ninja are excited but quickly ends when the Stranger frees Wu and flies away with their via hover-copter. However, the Stranger leaves a scale behind. Nya decides to give Lloyd and Garmadon a message.

The Curse of the Golden Master

Ninja ready to fight

The Hover-copter was eventually converted to solar power, the Ninja returned to New Ninjago City with Nya and P.I.X.A.L. There, they reunited with Borg and explained their suspicions as to who stole the hard-drive containing the Overlord.

They eventually came across the Stone Army Vault, only to find the seal had been opened. Upon confronting Skales, they learned that the Serpentine had reformed and the Snake King even had a son. The Ninja and Nya were lead to a campfire where Acidicus told them of the Curse of the Golden Master, and how they believed it was referring to Lloyd. While the Ninja discussed the curse, Nya expressed her confusion that if the Serpentine didn't take the hard-drive, who was the culprit.

Both questions had to be put on hold though, as Nindroids suddenly attacked the place, and Kai ordered the other Ninja and Nya to protect the Serpentine. The Ninja finds out that the Electrocobrai are their power source. Skales tells them at the Curse of the Golden Master is upon them, and says that they would not be able to assist the Ninja because they're choosing to stay out of the conflict. The Ninja then return to the surface, but not before Skales telling them the one Serpentine that is fond of electrocobrai: Pythor.

Enter the Digiverse

Golden Kai

In the top of the Borg Tower, Borg prepares the device that will lead the Ninja to the Digiverse, where the digital overlord was, a digital world where they will be able to gain access to the Tower's central computer and fight the Overlord directly. When Jay points out that the hard drive is still missing, Borg explains the device will "download" the Ninja themselves, along with the Techno Blades, into the computer where the Overlord dwells. He also explains that this is the only method to succeed, as it will be a matter of time before the Digital Overlord fully drains Lloyd's power.

Although apprehensive, the Ninja are "downloaded" successfully, and they wake up in the Digiverse. In no time, they begin mastering the advantages of the digital world, except for Kai. the Ninjas begin their trek down toward the Tower's central computer—ironically below the Tower, where the Overlord had been defeated years before. When the Overlord realizes they are close to him, he attempts to immobilize them but fails due to P.I.X.A.L. electronically interfering from outside. He then turns the digitized New Ninjago City upside down, but the Ninja keep moving with their digitized vehicles. Kai almost died when he tries to jump off the digital Borg Tower because his vehicle disappeared, but gets rescued by Zane. Together they get to the top—that is, the bottom—of the tower and insert the Techno Blades only to find the Overlord severed the circuit to the motherboard.

The Ninja are severely beaten by the Overlord as he consumes more of Lloyd's golden power, proclaiming his becoming a true "golden master" of the real world and the digital world. Strengthened by Lloyd's proclamations that the Ninja always have each other's strengths to fight together, Ninjas fights off the Overlord's influence and turns gold and, using Lloyd's shared power, reroute the circuit to the motherboard and completely destroy the Overlord virus from the system, initiating a reboot.

Codename: Arcturus

At the Temple of Light, Lloyd gives up his Golden Power to restore the Ninjas' elemental powers. Meanwhile, at Borg Tower, Master Wu spots General Cryptor aboard a train heading for Ouroborus. going through a road near where Kai is.

Kai stands in a gas station flirting with a girl when P.I.X.A.L. calls him and tells about the Nindroids approaching. He jumps into his Prototype X-1 machine car and heads to the highway. When he comes to the bridge, he accidentally fires rockets to the sky which got spotted by Pythor who was driving in a leading fuel truck with General Cryptor. He then launches Nindroid flyers to hunt him and destroy his car.

Kai fighting with Min-Droid

Kai successfully repels their attack, but Cryptor fires rockets at a hill above them and soon rocks that got separated from the hill fall down to his car. They block the road, but Kai and P.I.X.A.L. destroy them with rockets. To hunt down General Cryptor's truck, P.I.X.A.L. activates his interception bike which Kai is unable to control so he bumps into the edge of the oil tank. He gets up to its roof and fights Nindroids, using his new fire power and Spinjitzu. This proves to be a mistake as he realizes that his fire power lit up the oil tank and that it's going to explode. Soon they got to a tunnel, where the Min-Droid attacks him. The X-1 machine, remotely driven by P.I.X.A.L, accidentally scrapes an oil tank so gas starts leaking. It soon gets to flame from the sparks of p Min-Droid fighting Kai. When the fire comes to the leaking tank, the whole tank explodes but Kai jumps off to Pythor's truck and saves himself. He stays beneath his truck and hears Pythor talking to the Overlord by radio. He tells people in Borg Industries that the Overlord is alive, but gets captured by Pythor who takes him to the lost city of Ouroboros.

By the time Zane, Cole, Jay, and Lloyd get to Ouroborus, they don't find anything new around until a huge door below them opens and they fall into an underground base where they find a huge rocket called "Arcturus." They realize that the rocket will lead Pythor and his Nindroid minions to space and reach the Golden Weapons from the star where the Mega Weapon was destroyed. Lloyd tries to stop him from lifting the rocket but Overborg stops him. With help from a freed Kai, the other Ninjas hold off the Nindroids with their new elemental powers. Pythor initiates the countdown for the rocket to launch into space, so Lloyd leads the Ninja into it just in time.

The Void

Ninja in space

The Ninjas are in the Arcturus rocket as it flies through space. They make contact with Borg Tower and voice their concerns about their current predicament to Wu, Garmadon, Nya, and P.I.X.A.L.

The Ninja put the space suits just as the rocket disengages its unneeded engines. However when they climb up toward the door leading to the cockpit they are attacked by Nindroids, who fire on them with laser guns.

Following Jay's initiative of going commando and learning that their Spinjitzu does not work in zero-gravity, the others take the laser guns too so they successfully repel the attack. Soon the Arcturus enters an incoming comet's tail and is battered by massive ice meteorites.

The Arcturus rocket crashes on the comet's surface where the melted and fused forms of the Golden Weapons are located. The Nindroids and the hidden Ninja discover them as Jay excitedly finds an extraterrestrial beetle. Unfortunately, said bugs eat anything metal—a fact that reaches them from Nya too late. While the Nindroids get away with the golden mass aboard their ROV, the Ninja follow pursuit on their own while using the pursuing bugs against their robotic adversaries. The Ninja eventually succeed in taking Cryptor's ignition key to the rocket, so that they cannot leave the comet with the Golden Weapons and take them to the Overlord.

However, their victory is short-lived when they find another bug swarm among the rocket—chewed up in pieces. Seeing this as well, Cryptor and the other surviving Nindroids use their built-in boosters to fly off the comet with their golden prize. Stranded on the surface with the insects, the Ninja report to the others that they had failed and are not coming back home.

The Titanium Ninja

Kai's shield

In space, the Ninja despair after repeated failed attempts to escape. However, Lloyd refuses to give up, suggesting that they use their elemental powers and everything around them to restart the ship. Heartened by Lloyd's words, the Ninja repair the ship and use Zane as a power source. Though Zane gets overheated by the strain, they manage to fly back to the Earth—to land safely, the Ninja uses a new technique: elemental shields.

P.I.X.A.L. uses a motorcycle to catch up with her friends, using her power to land them on their vehicles. As the Ninja reunite with their allies, Cyrus Borg tells them that they should head for the Temple of Fortitude, a place where the Overlord and the First Spinjitzu Master battled long ago. He claims there's a shield at the place, so the Nindroids won't harm them, and there is something he wants to give them that may help them save the world.

The Ninja start traveling to the temple but pause when they see the Golden Master's path of destruction. Lloyd reminds his friends that the only way to save Ninjago is to reach the Temple of Fortitude, but the Overlord sees them and uses a massive Spinjitzu tornado against them. The Ninja swiftly run back, rendezvousing with Cyrus Borg, Wu, and Garmadon. There Cyrus Borg gives them the ultimate weapon—a pill. Borg then explains that it was no ordinary pill, it could make anyone shrink. Garmadon and Wu decide to would hit the pill straight into the Overlord's mouth. Borg gives the Ninja armor which protects them from some attacks from the Overlord.

The Ninja go into Ninjago City, when an item hurls at them but are protected since they have on the armor. Wu hits the pill, which heads straight to the Overlord's mouth, but Pythor sacrifices himself and swallows the pill instead. As a result, Pythor shrinks down to the size of a worm. The Golden Master is outraged that the Ninja tried to shrink him. He obtains the Ninja with his Golden Power only to miss Zane. The Ninja of Ice tells his friends to support him one last time, and the Ninja bounce him. Although, during the process, he landed and touched the Golden Master's gold. He refused to let go, admitting the fact that Ninja never quit, which frees his friends. He remembers his past, and freezes the Overlord which also killed him and the Golden Master. The Ninja are disappointed that Zane has passed, and proceed to his funeral.

Borg makes a speech on how he thought technology was the best way to destroy problems but instead cost more. He now names Zane the Titanium Ninja and passes the microphone to Kai. The Red Ninja claims no one knew what powered Zane, and he thought it was brotherhood because that's how Zane powered him. Saying that Ninja will never be forgotten, Kai says no matter where Zane is, he'll always be part of the team. When he finished his speech, snow began to appear.

Tournament of Elements

The Invitation

Kai in the docks

Following Zane's sacrifice, the team has split Kai with going to wrestle in an underground Slither Pit known as the "Red Shogun." After a fight, he rests to drink some juice, when Lloyd arrives and asks Kai to return to the team. Kai refuses the offer, saying Lloyd doesn't need a team and wishing it was him who gave his life instead of Zane. Lloyd reminds him he always wants to be the one, using his obsession with becoming the Green Ninja as an example before telling him to think about someone other than himself. Lloyd goes away telling Kai to meet him at a noodle shop as Kai ponders on it.

Very soon, Kai goes to the park to see the statue of Zane as the Titanium Ninja, causing him to reflect on his time with a late friend as he sees the Falcon appear. Kai then decides to take up Lloyd's offer and goes to see him. However, Kai wasn't the only one to meet the Green Ninja at Chen's Noodle House: Jay and Cole had also been convinced and has met Lloyd there too. Lloyd informs the Ninja of his new plan: finding a new Ninja. The others completely dislike the idea, saying Zane was not replaceable and Kai states maybe without Zane there was no team. They quickly get interrupted by Eyezor and his gang who attempt to rob the store. However, the Ninja intervene quickly defeating the thugs who run away.

The Ninja pursue them and go to the back of the shop but see no sign of the thugs and instead, a drawn picture of Zane attached to a shrine with a note stating that he was still alive as well as an invitation to the Tournament of Elements.

They decide to accept and are walking onto the ship when Garmadon comes and tries to stop them, warning them that Master Chen, who invited them, is a dangerous man. Lloyd retorts by saying that they have to find Zane. Against the better judgment of Clouse, Chen's second-in-command, Garmadon, accompanies the Ninja on board, where they meet the other Elemental Masters.

While onboard, Kai and his friends see other people who received invitations and saw they had powers. Kai asked Garmadon why he or Wu never told him there were others with abilities like them as Garmadon explained there were some things they didn't want them to know. He then reveals everyone on board was descended from an Elemental Masters listing a few examples of the others on board. Kai then notes the same went for his sister but states she can't do what he can as Garmadon tells him its possible Nya can as she only needs the power to be awoken to do so.

Kai begins to take an interest in a cloaked woman and questions Garmadon on what her element is, but he didn't know as he'd never seen her before. Soon enough, Kai sees Karlof, the Master of Metal trying to take the woman's cloak and starts to insult him until the two begin fighting all over the ship. Just as Karlof pinned Kai and was about to finish the fight, Clouse calls it off: the woman helps Kai to his feet and copies his powers without him noticing. Clouse announces that they reach Chen's Island, and while the Ninja wonder where they will find Zane.

Only One Can Remain

Kai using his Fire powers

The contestants of the Tournament of Elements finally reach Chen's Island, rushing to be the first to see and go into Chen's place. The boat sets dock, allowing the people to escape the ship. The Ninja group together, while Kai loses conscious staring at Skylor. Kai immediately blocks the Ninja's path, telling them that "Girls go first." The heroes of Ninjago reach the underground fortress located on the island. Clouse arrives, commanding the contestants to welcome Master Chen. Master Chen brings his servants to welcome each contestant to their room. The Master of Fire enters his room first. His earliest discovery was his Kai poster. He wanders into his patio curiously, and glances at a familiar figure, who is also his neighbor: a Ninja girl clad in an orange Ninja gi. Kai attempts to introduce himself and use his Elemental power to win her over, but the girl—Skylor, by name—throws him off by flirting back, making him quickly lose control of the fireball in his hand. His reaction to the burning seems to amuse her.

Master Chen announces the competition starts now. Kai and Skylor see a Jadeblade on top of their roof. Skylor preforms backflips to get to the location of the blade. Kai jumps up too and accidentally knocks her down. He managed to grab her leg, stopping her from falling. He flings her up; however, she reaches the blade, now making only one Jadeblade left and Karlof heads to the last one. Kai realizes and follows Karlof. Kai's archenemy won the battle, but before Karlof could hand it in, Kai unscrewed his Metal fist, getting a chance to win. Kai flies to Chen's location putting the blade in its spot to win.

Since Karlof has lost the contest, he is sent to Chen's secret location in the dungeon. Kai suggests they have a meeting later in his room. The Ninja had entered Kai's room with the exception of Jay since Skylor has arrived, therefore making the Red Ninja push Jay. After Skylor had re-entered her room, Kai helps Jay get up, apologizing for the mishap. The Ninja discuss the tournament while Cole lays down on Kai's bed, accidentally triggering a button again which reveals a secret entrance. Cole informs his friends, and they silently travel to the secret room. In the secret cave, Kai, Jay, Lloyd, and Cole hear Skylor shout in her room. They observe her room with little peeking holes, and surprisingly find her using the Fire element, which causes Cole to tease the Red Ninja by singing that "Kai's heart is on fire." Soon, the Ninja face Chen's minions but silently hide behind a rock while defeating the four minions. After they defeat the minions, they take their outfits to blend in and look like Anacondrai warriors and go to Chen.

Master Chen then has his followers bring out a captured Karlof, and the Ninja are horrified to witness him steal Karlof's power with his staff. Cole soon notes that Chen used Ice when he cast the spell, which meant he already stole Zane's power too. As the Ninja realize Chen's goal is to steal everyone's power, their identities are revealed and Lloyd commands the Ninja to run out of the place. While running, Cole trips on a booby trap which sets out traps and a huge snake (which Kai notes is the second biggest snake he's seen).

Running away from the giant snake, they finally make it back into Kai's room. They now promise to stay within the rules until they find Zane.


At Chen's island, the Tournament of Elements is on break. All the competitors are in the cafeteria eating lunch. The Ninja are still shaken up from Chen stealing Karlof's powers and try to come up with a new plan to find Zane. Chen then announces the six masters competing to get the jade blade next. The masters consist of Griffin Turner, Gravis, Ash, Bolobo, Neuro, and Kai.

Kai vs. Ash

The match between Kai and Ash takes place on a bridge over a volcano, with the jadeblade and the competitors on a wooden bridge. Kai goes straight for the blade, but Ash flips the bridge over, causing it to fall on a rock below. Kai climbs under the bridge and attempts to kick Ash, but the master of smoke uses his powers to evade the attack. Kai continuously attacks Ash, with none of his blows landing while Ash keeps disappearing and reappearing and his punches landing, eventually sending the master of fire through the bridge and hanging. Kai initially struggles to hang on to the plank worrying Skylor, but he flips himself back onto secured planks and uses his Spinjitzu to push Ash back though the end result is the same. Lloyd encourages him to use his powers, so Kai then launches multiple fireballs, only for Ash to dodge them while they begin burning through the bridge. As Kai and Ash's battle continues, Clouse attempts to use his Magic though Chen prevents him from doing so, enjoying the fight. Ash manages to apprehend Kai, but he launches one more fireball which successfully burns through the last of the bridge, sending both of them onto the rocks below. The two then battle in midair over the Jadeblade where they're evenly matched until Ash makes for the blade. Kai then attacks him, where he uses his powers to avoid being hit: Kai uses this to take the blade and end the match with Ash eliminated.

Soon, most of the contestants are looking at the brackets and when the Ninja see for themselves, they're shocked to find Cole and Jay have been set up to fight next. The Ninja confront Clouse about this, but he brushes it off. Kai suggests they ask Neuro for help, but he denies as helping them might hurt his chances in the tournament. Lloyd manages to convince him by letting him read his mind and seeing what happened to Karlof. Later Neuro tells Kai what he discovered: Clouse has a spellbook where the page marked 149 has a spell that requires everyone's powers, though he couldn't find a way to stop the fight.

During the battle Jay tells Cole to take the Jadeblade as he himself is lucky to still be in the tournament, which he does, but throws it to Jay like a true friend, saying he should have backed down with Nya before telling the Blue Ninja to win it all. Cole loses, though Garmadon tells Kai, Lloyd, and Neuro that he did the right thing.

Ninja Roll

Kai with other Elemental Masters

Kai is seen running around outside the temples, appearing to be lost. He then runs inside one upon hearing Chen's voice announcing the next fight. Inside, Skylor is about to fight Jacob, the Master of Sound and they begin to smash vases in order to find a Jadeblade. Kai soon arrives and makes his way to his seat, stepping on everyone's toes in the process, soon realizes Skylor's fighting just as she sets Jacob's sitar on fire, while Jay fills Garmadon in on his crush on her until they found out they might be related. Garmadon explains that Skylor's element isn't Fire—it's Amber, meaning she can absorb other elements with a single touch, which immediately brings Kai's feelings back. After Jacob is eliminated, Chen announces he initially wanted to give everyone jewels for their work in the Tournament, due to Jay's fight with Cole yesterday, he rejects the idea and takes away everyone's rooms, forcing them to sleep in the dining hall. As Jay and Kai berate each other while the other competitors leave, Garmadon warns them that if they don't make friends with the others, they'll try to eliminate them by any means necessary. While the competitors rest, the remaining three Ninja discuss a plan but quickly jump back to their beds just as Clouse arrives. He orders Master Chen’s servants to add roller-skates to everyone’s feet, making the contestants curious. Clouse only says Lloyd will fight Chamille, Master of Form before leaving. Lloyd is confused as to who Chamille is, to which Kai seemingly explains how she can disguise herself to find another's weaknesses. Lloyd points out his only weakness is his aching back, but as Kai skates away, he appears on the other side, struggling to balance on his skates. Lloyd soon realizes that Chamille, disguised as Kai, tricked him into pointing out his only weakness to her.

During the Thunderblade Race, Skylor asks Kai what's left from stopping him from winning the tournament if Lloyd was out, to which he says he doesn't think of it before she knocks him down. By now, Lloyd and Chamille have each gained a point and have caught up to the others, who stop Lloyd from passing. Jay decides to make an opening by shocking Neuro, which works and stops everyone else: however, the plan fails as Kai accidentally knocks into Lloyd, causing him to fall behind by one point. Chamille orders Shadow to hit Lloyd's back, succeeding, and making him drop his Jadeblade. Mr. Pale then takes it, only for Jay to take it back and knock him off the track. Everyone does whatever they can to stop the Ninja (with only Kai taking the hits), with Chen even releasing a buggy to extend Chamille's lead. Skylor comes up to Kai, saying he's convincing and Lloyd will soon be eliminated.

With the score now 8 to 5, Kai decides to help despite not keeping balanced and uses his powers to hit Chamille and making her drop her blade, allowing Jay to take it. Skylor attempts to berate Kai for what he did, though he snaps and says that as Ninja they stick together, causing Skylor to regret trusting him. Jay approaches him and informs him of Lloyd's progress though Kai now realizes Garmadon was right about not trusting the others. He then states if everyone knew about Chen's true intentions, they'd help: Chamille then takes back her Jadeblade. Kai latches onto Skylor, explaining what he meant and revealing the real nature of the tournament: upon mentioning the spell, Mr. Pale, Shade, and Griffin become interested and are convinced upon Neuro's testimony. Chamille attacks Kai and he lands near the buggy, allowing him and Skylor to take it. They drive up to Lloyd and let him take it, where it transforms into his color. After Lloyd wins, Chen refuses to have the event count, claiming Lloyd cheated and is disqualified, though Griffin stands up for the Green Ninja and states Chen is the one who cheated, where the master claims what his rules says, goes. Mr. Pale, Kai, and Jay protest if Lloyd's out, then so are they whereas Skylor states if everyone is eliminated, there is no tournament. With that along with Clouse confirming it, Chen is forced to comply and eliminates Chamille. As everyone cheers for Lloyd, Skylor warns Kai that because of this, Chen will do anything to eliminate the Ninja. Kai then states that as long as everyone sticks together, there's always hope.

Spy for a Spy

As it turns out, the banquet is being held for the eight remaining competitors who have made it to the second round. Chen tells the remaining eight that he knows that they have a secret alliance and that that the tournament is about stealing everyone's powers. To crumble the alliance, Chen lies and tells that whoever wins gets his Staff of Elements. Nya goes to the banquet and tells the Ninja that she's undercover and that one person in their group is a spy. This leaves the Ninja curious before Skylor approached Kai with a fortune cookie that says Cole and Zane will be breaking out, which elates the Ninja that Cole found their lost friend.

The Ninja searched for the spy

Later in Kai's quarter, all the fighters try to determine who the spy is. Garmadon suggests checking their backs and the one who has a snake tattoo on their back is a spy. Eventually, it comes down to Shadow and Skylor, the latter attempting to get Kai on her side by saying he didn't trust her: he stated he did and wanted the others to trust her, too. Before she did, Shadow made his escape declaring he wasn't the spy or the ninja's friend, so the Ninja and the remaining masters assume Shadow is the spy. Kai tries to apologize to Skylor, but she refuses to listen and shows him and the Ninja her back without a tattoo, leaving him guilt-ridden. Unbeknownst to them, Skylor truly was the spy and had hidden her tattoo using the power of Form.


For the next round of the tournament, Kai and the other remaining fighters boarded a blimp and were taken high above Chen's Island. While on the blimp, Kai argued with Shade as everyone still considered him the spy as Shade states he wants to fight Kai in the next match. Once they were high above the island, Chen revealed to Kai's horror the objective of the next round was to capture Nya, who had proof of Chen's plan. The masters were then dropped out of the blimp along with parachutes and Kai was successful in claiming one. A few seconds later he landed close of the island's volcano, resulting in the parachute being set alight and burns him to the point that he screams in pain.

Kai and Skylor.

While searching for Nya, Kai noticed a rustling in the bushes and ignited his hand with a fireball only for it to be Skylor. The Master of Fire asked if she would help him in his search and the two set off together. However, they had not gone far when they noticed a massive fireball across a pond. Kai began hopping from log to log to get across, but Skylor froze the pond to get there quicker, causing Kai to realize she saw Zane and that she was the spy, having used Chamille's power to hide her tattoo. To his even greater surprise, she revealed that Chen was her father, who using the power of smoke, appeared beside them.

A devastated Kai captured.

Chen declared that Kai's time in the tournament was over and ordered Skylor to seize him, though Kai used his fire Spinjitzu to get to land. There, however, Chen used his staff of elements to trap the master of fire in vines, capturing him. Kai was taken to the D.B. Express and thrown in the vengestone prison along with Jay and the other elemental fighters. He was told by Jay that Lloyd would come for them as they were taunted by Chen who wanted Lloyd to come try. As Chen laughed, Kai stared at Skylor heartbroken by her betrayal.

The Forgotten Element

The captive Elemental Masters brought before Chen.

In the Anacondrai Temple, Kai, Jay, Griffin Turner, Neuro, Mr. Pale, and Shade are led in chains made of Vengestone to have their powers taken away. As most of the masters lament on not heeding the ninja's warning, Jay tried to maintain positive attitude which Kai berates him for given the situation.

Upon being brought before Clouse and Skylor, Kai questions how she could help her father knowing he'll need her element for the spell as well. Saying she had no choice, Kai asks who planned to have him fall for her, which shocks Skylor. Chen raises his staff and takes the master's powers. Upon Chen ordering for the masters to be sent to the factory, Skylor begs for Kai to be spared saying he can help them which he complies with.

Chen shows the Red Ninja his trophy collection (containing parts of the Ninjas' past adventures), though Kai angrily responds that without the staff, he'd strike the villain down. Chen noted even without his power the fire still burns in Kai before he explains that unlike Kai and Skylor, who got her powers from her mother, he himself had no abilities and was told he'd amount to nothing. He then shows Kai a portrait of Arcturus and announces with Lloyd's power, he'd be unstoppable since he will turn his followers into Anacondrai. When Kai asks why Chen was telling him this, he tells Kai he knows he's still jealous Lloyd became the Green Ninja and offers to give him the power he wanted to try for so long. However, Kai refuses to betray his friends: Chen counters this by promising dark secrets about his parents his masters never told him which surprises Kai. Before he can inquire about this, Clouse comes to tell him of Lloyd initiating his plan soon and they leave Kai to consider his offer.

After Lloyd sneaks into Chen's Palace and falls into another one of Chen's trapdoor into a cave made by Clouse's serpent which pursues him. Kai appears and gets the Green Ninja out and advises him of the situation and plan, but Lloyd refuses and says he needs to face Chen. With that, Kai apologizes to Lloyd blowing out his torch and leaves while Lloyd finds himself with Chen in the throne room. Shocked that Chen managed to turn Kai against him, Lloyd proceeds to battle while trying to talk some sense into Chen. However, the man uses everyone's elements to overwhelm the green Ninja and defeats him.

Kai claims he switched sides. . . .

Nya wakes up in the dungeon of the snake where, along with Garmadon, she's chained to a post. Chen, Clouse, and Skylor approach and inform them of Lloyd's defeat and that his power will be taken soon. Nya questions how they were able to defeat him to which Kai enters, saying Lloyd never stood a chance alone. Garmadon, now enraged of Chen turning the Ninja against each other like he did to their ancestors, grabs Skylor and threatens her unless he and Nya are released: they call his bluff due to his reform and he's forced to release Skylor, shocked with her father.

. . . but soon confirms otherwise.

Clouse opens a tunnel door for his snake to enter after its nap while Nya tries to talk sense into her brother as Kai tells her this was it was to be but winks at them, revealing he only pretended to switch sides to gain Chen's trust, relieving them. As Chen and Clouse leave to prepare for the ceremony, Kai pulls Skylor back and explains he can get the staff. Skylor asks why he'd tell her after her betrayal: Kai states she let him go for a reason, with her feeling for him being the most obvious choice which she admits.

In the ceremony Lloyd questions why Kai would betray him, though he tells him not to worry but keeps up his act. Chen then has Skylor give up her powers. By now, Skylor has completely lost her power and Chen proceeds to take Lloyd's Energy. As Clouse begins the spell, Kai tells Chen he forgot one more element: the "element of surprise." Skylor then kicks the Staff of Elements out of her father's hands and Kai uses it to free Lloyd, who realizes Kai's plan. With the staff, Kai holds off the Cultists and manages to freeze Clouse. Lloyd tells him to destroy the staff, but Kai begins to become corrupted by its power. Just before he uses it on Lloyd and Skylor, all the escaped elemental masters burst in (among them being Jay, Cole, and Zane) causing him to drop it. Regaining his senses, Kai spots the staff and runs to it quickly grabbing the staff before Chen does and destroys it, restoring everyone's elements allowing them to overpower the Cultists.

The reunited Ninja about to do Spinjitzu

With the Ninja reunited as a whole once more, they do Spinjitzu and defeat the remaining Cultists before Chen, Clouse, Eyezor, Kapau, Chope, and Zugu escape with Skylor as their prisoner.

With Chen in hiding, the Elemental Masters capture the remaining Cultists and seize control of the island. Nya and Garmadon assure Kai they'll find Skylor while Kai expresses surprise at finding an old friend and making new ones, including a new kind of friend in Skylor. Garmadon once more assures they'll find her, with the battle now over for the time being, Kai and the others laugh at Zane as he dances and sings, just like at Dr. Julien's lab.

The Day of the Dragon

The Ninja await Chen

On Chen's Island, the masters make sure that Chen and his forces can't escape by destroying any means of the island. As they do so, the Ninja search the palace and forest but find no sign of Chen as Lloyd comforts Kai about Skylor, saying that while she couldn't pick her family, she picked a good friend, with the addition of Cole saying with no other way off the island, they'll find them. Garmadon congratulates the five on bringing the Elemental Masters together and sticking together, though he warns them to keep their guard up. Later on, Griffin Turner and Neuro inform the Ninja, Nya, and Garmadon that Chen plans to use Skylor's absorbed powers to finish the spell and turn the cultists into Anacondrai.

After getting Skylor's location, Kai takes off on one of the crushers while Jay takes the mech, Garmadon and Cole take the Jet, Zane takes a buggy, Nya takes the DB Express and Lloyd leaves on his dragon. As Skylor is now being chased by Eyezor and Zugu, she is saved by Kai, who crashes his own bike into the two generals' bikes. Kai takes a rocket board for himself and the chase begins again when Chen starts to pursue them in the bladecopter. Combining their Fire, they create a smokescreen which Chen flies through, sees Kai, and notices Skylor disappeared not seeing she used her Form to disguise herself.

Kai emerges from one of the buildings, having alerted the team and takes an interest in exploring the town, but brushes it off to bring Skylor back. However, the two are ambushed by Kapau and Chope and captured in an Element-blocking net. Later in the Crystal Caves, the transformation is revealed to have begun, Kapau reciting the spell in Clouse's place. As Chope finishes the spell (Kapau having fainted from its effects), Kai urges Skylor to resist the transformation. However, the transformation is completed which Chen cheers at for awhile. Kai attacks Kapau, Chope, and Chen though none of them are affected due to their thick Anacondrai skin allowing Chen to knock Kai away Skylor breaks free and attacks her father before he can finish Kai.

Kai and Skylor on an Elemental Dragon

Accepting her new form, the red Ninja leads her out of the cave and return to the coast riding Kai's Elemental Fire Dragon supporting Zane's (who summoned a dragon as well) theory of conquering their fear, convincing and encouraging everyone to unlock their dragons. With dragons, they begin flying after Chen as Kai states that although Chen brought them there so only one of them would remain, he didn't think that together, they were one.

The Greatest Fear of All

On Dragons, the Elemental Masters fly to Ninjago in order to stop Chen and his army. They arrive a day after Chen; Kai wondered how they lost time as the others bring up they had to retrieve those who are not Elemental Masters and how hard it took for them to master summoning dragons. Once in Ninjago, they find Chen hasn't attack yet and when people run after seeing Skylor as an Anacondrai, Kai consoles her by telling her she's with them after she wishes says could still change.

To avoid causing a panic with Garmadon and Skylor, they take them back to the Samurai X Cave where they reunite with Wu and Misako to deduce Chen's next move. The Ninja visit Kryptarium Prison, where they speak to Pythor of how to combat them, though he is initially against speaking to them until he sees the transformed Garmadon. The prison soon comes under attack by Chen's Cultists as Kai, Jay, and Cole fight them while the others realize Pythor holds the key to keeping the spell permanent. Wu and his family escape making sure Pythor doesn't fall into the Cultists' hands as the Ninja keep them busy, as the prison is put on lockdown.

The fight soon causes the release of the prisoners and Cole break through the walls since the metal door can't be broken. The Ninja run through the prison with the inmates following them and make it to the courtyard finding the Garmadons fighting the Cultists. Kai inquires if they had Pythor as Wu finds that the Cultists have made off with him. To ensure the prisoners don't escape, Wu stops Cole from breaking any more walls and Zane creates a trail of ice for then to run out of the prison, which Kai destroys so the prisoners can't pursue them, leaving the inmates to be taken back to their cells by the warden and his guards.

The Ninja plan to stop Chen's invading forces

They return to the Samurai X Cave, where Nya tells them Chen has shipped out several noodle trucks that could hold swarms of Anacondrai Cultists. The Ninja contact their allies to stop them before their arrival but the trucks separate into going off to other directions, where Misako states there are several villages.

The Ninja and the Elemental Masters summon their Dragons and each pursue a truck. Kai follows one through the city and manages to damage it and capture the driver. Kai opens the truck only to find it empty as he realizes too late that Chen tricked him and his friends to split up. The fear that he put many people in danger causes him to lose control of his dragon, leaving him unable to do anything about it.

The Corridor of Elders

Kai and the other elemental masters are scattered all around Ninjago, after chasing down the decoy trucks. Nya attempts to contact them from the new Destiny's Bounty. Lloyd instructs Neuro to send a message to the other elemental masters ordering them to Nya's Samurai Cave, where she informs them that Chen has taken over the entire eastern coast. Wu points out that the Corridor of Elders will be the best place to make their final stand, and the elemental masters agree. The Ninja journey all over Ninjago to rally support from the citizens, with Kai going to the comic store for help.

The Ninja, elemental masters, citizens, and Serpentine get to the Corridor and start the ultimate battle against Anacondrai. Pythor escapes Chen's camp riding a rat and carrying Chen's spellbook. He gets to the battle and tells Lloyd to take him to his father because he knows the way to end the battle. Later, Lloyd opens the portal to the cursed realm and unleashes spirits of Arcturus and his troops who quickly curse Chen and his soldiers turning them into ghosts. They all get hovered into the portal, which then explodes after closing off, ending the war.

The Ninja and Elemental Masters celebrate

The Ninja and the elemental masters then celebrated their victory, with Kai and Jay being hugged by Karlof as they all promise to offer their new friends aid in the future as they part ways.

Dareth ruining the moment of Kai and Skylor

Later, Kai asks Skylor to join the team but said that she has the noodle-business to run and they almost kissed they get interrupted by Dareth. They part ways although Skylor promised to Kai that she will keep in touch with him.

The War over, the Ninja look forward to the future.

On the top of the corridor, the Ninja, Wu, Misako, and Dareth sit around a fire on a broken statue, watching construction workers building a statue of Garmadon in the corridor. Lloyd tells that today they will say goodbye to a legend and burns the book in the fire.

Shadow of Ronin (non-canon)

Kai in Shadow of Ronin

After relocating to Spinjago, Kai retold the events of Chen's Island to the other Ninja, though his description was greatly exaggerated with everyone complimenting him and a wild twist. Following his story, the Ninja began to train. However, they were interrupted by the arrival of Ronin, who stole the Ninjas' memories using the Obsidian Glaive.

In the hopes of finding a way to restore their memories, Wu sent the Ninja to speak to Hibiki at Kryptarium Prison. After dispatching with Ronin's goons, they learned of the Inky Lemonberry in the Toxic Bogs and went to pick up Nya from Ed & Edna's Scrap N Junk. To get there, Kai used his Blade Cycle, through quickly fell under attack by Blade-Cycles and Rattlecopters.

SoR Obsidian Sword.PNG

Once he arrived in the Toxic Bogs, Kai expressed concern about eating something that grew in such an unhygienic place. Nevertheless, he drank the Tea of Insight and learned that in Obsidian Sword was hidden in the Fire Temple.

Kai accompanied the other Ninja to the Frozen Wasteland where Zane acquired his Obsidian Sais. There, Zane remembered that Ronin was the one who had taken them to Chen's Island and he and Cole recapped Zane's death for Jay.


Before they could go to the Lightning Ruins to retrieve Obsidian Nunchucks, however, Nya called Kai reporting that the Nindroids were attacking New Ninjago City. Kai and the other Ninja caught up to Nya in the park just as a jet crashed into the nearby Fireworks factory. Upon talking to Cyrus Borg, Jay was overjoyed to learn that his Lightning powers would be vital to stopping the Nindroids, and the Ninja quickly headed to the Floating Ruins. With the power of lightning once again at the Blue Ninja's command, the Ninja were able to shut down the power and deactivate the Nindroids. Their victory was short-lived however as Ronin soon arrived and attacked the Ninja using the Lightning Forge, forcing the Ninja to retreat.

Later, Master Wu realizes that Ronin plans to bring back Chen. To avoid this he sends Jay, Cole, and Dareth to recover the Forge of Ice. Meanwhile, he, Kai, and Zane recover the Forge of Fire which is inside the mouth of an active volcano. After recovering the forge they reunite with Jay, Cole, and Dareth. Suddenly Ronin ambushed them with the Lightning Forge, though Dareth and Zane managed to escape. After recovering the last two forges he released the Ninja.

Back in Spinjago, Sensei Wu realizes that Ronin needs the Primal Fulcrum. They travel to the Fangpyre Cemetery to find that Lloyd and Misako are there to help them. Unbeknownst to the Ninja, Ronin had used the Obsidian Glaive to alter Misako's memory to believe that the Ninja had betrayed her. After finding the primal fulcrum, Misako tricks the Ninja into activating a fail-safe. After destroying the Obsidian Glaive, Ronin and his goons escape and destroy the entrance to the room in order to avoid being followed.


Later, the Ninja follow Ronin to Chen's Island to stop him from opening a portal to the Cursed Realm. But the Ninja failed and entered the now giant-sized portal using their Elemental Dragons, along with the Ultra Dragon, in order to stop Ronin once and for all.

After they had searched different portals and failed to find him, they managed to build an entrance to the portal he was hiding in. they were finally standing face to face with Ronin for one last time, but Ronin then revealed a triumph card. Using the remaining power of the Elemental Forges, Ronin transformed himself into a giant elemental creature and fought the Ninja. But as the battle continued, the Ninja manage to destroy each of the Forges that powered his elemental form, until they were all destroyed, and Ronin was then forced to flee on R.E.X. once more, but not before he saw a giant, green, ghostly arm coming out of the now closing portal. After Ronin escaped, the ninja managed to escape from the Cursed Realm as well. Kai points out that Jay had lost his pants again. However, this part turns out to be Kai exaggerating again, much to Jay's frustration.


Winds of Change

With Garmadon gone, Kai took Lloyd under his care and promised to watch over him. He and the Ninja used their Elemental Dragons to capture a Fangfish that had been terrorizing a local village, though Kai bragged that he once had caught one twice as big. Upon returning successful to Wu's new tea shop Steep Wisdom, Kai and the others were sent by their Master into Ninjago City to advertise the new store, yet without using their powers. While they obeyed their master at first, after failing to attract anyone Kai decided at use his elemental powers to create a teapot out of fire.

Unfortunately, Morro possessed Lloyd's body and the other Ninja lost their elemental abilities. They returned to Wu for answers just as the tea shop fell under attack by the Master of Wind. Kai attempted to help Lloyd regain control of his body, but was taken away by the Ninja as the fled in the Destiny's Bounty just as the Green Ninja was starting to regain control.

Ghost Story

Morro soon caught up to them using his Elemental Dragon and while the masters of earth and lightning fended him off, Kai and Zane escorted Wu to their quarters for him to make an imprint of the staff's secret message. The ghost ninja crippled the flying vessel however and soon confronted Kai who was almost thrown out of the Bounty. He was saved by Zane, but the ship crashed in the Forest of Tranquility.

The Ninja made camp and Wu told them of his past with Morro. That night Kai dreamt of him promising to look after Lloyd, only for the Green Ninja to be eaten by a Fangfish. He was awoken by a walloper to find that Misako has arrived and discovered that the first symbol means Airjitzu, a martial art created by Master Yang, though discover that Ronin had recently stolen the only known scroll. The Ninja mount wallopers and Kai leads them towards Stiix where Ronin was keeping the scroll.

Unfortunately, their head start was lost when Kai lead them away from Stiix rather than towards it. After Zane pointed this out, Jay and Cole elected to follow Zane instead and they soon came across train tracks leading to Stiix.

After nightfall, they came to a train station and stopped, intending to rest. However, they were soon beset by Wrayth on the Chain Cycle and engulfed in a frenzied battle against the ghost menace. Incidentally, he defeated himself when his chain hooked on a nearby water tower and poured its contents onto himself. The Ninja were left stunned by this, but realizing that a passing train was headed to Stiix, quickly ran after it.

Stiix and Stones

The Ninja eventually arrived in Stiix and confronted Ronin in his shop. The thief demanded a high price for the scrolls, but due to Kai's horrible negotiating skills, it was raised even higher. To earn money, the Ninja were hired to build a dock and Kai operated the crane. Unfortunately, a fly damaged the Titanium Ninja's language database and they ended up accidentally destroying the bridge. With Zane unable to speak, Jay took charge and decided that they should simply steal the scrolls.

When they did, however, Morro and his latest summoned partner Soul Archer had arrived at the shop for the scroll and summoned more ghosts. Using the Aeroblades, they got rid of the ghosts; unfortunately, Ronin called for R.E.X. and took the scroll but didn't get far thanks to Morro. Kai chased after Morro but failed to regain the scroll. In addition, Ronin offered to help Kai out of the strangle weed in exchange for something: Kai gave him everyone's business shares of Steep Wisdom. In return, Ronin told him of an alternate way to learn Airjitzu: Master Yang's Haunted Temple.

Kai admits to giving Ronin all their shares of the tea shop.

The Temple on Haunted Hill

Kai escapes the temple

During nightfall, the Ninja sneaked into Yang's Temple in order to retrieve the Scroll of Airjitzu. After pranking Cole, the Ninja tried to warn him that a thudding sound they heard was real. The Ninja were eventually forced to avoid all the obstacles Yang threw at them, and they decided to tie themselves together to prevent themselves from running away.

The Ninja then have to chase Morro into the attic, where Yang gave them the Scroll. After realizing the sun's almost up, the Ninja fled the Temple but was surprised and saddened to see Cole as a Ghost.


Kai began complaining about his new Deepstone suit because it was heavy, which he believed prevented him and the others from performing Airjitzu. Wu told him that it would protect him from turning into a ghost. Sometime later, Soul Archer shot him in his chest, but the Master of Fire didn't turn into a ghost.

Once they were nearing the highest peak of the Wailing Alps to beat Morro from reaching the Cloud Kingdom, Kai was the first to successfully do Airjitzu up to the top. He was then able to encourage Cole by telling him ghosts can't die, which helped him perform Airjitzu and allow them to beat Morro into the Blind Man's Eye.

Kingdom Come

Upon reaching the gates of Cloud Kingdom, Kai and the other Ninja were greeted by Fenwick. They were then shown inside the writing hall where the Ninja learned that the citizens of Cloud Kingdom were the writers of destiny.

Fenwick proceeded to inform the Ninja that Morro sought the Realm Crystal hidden in the tomb to unleash The Preeminent, before ushering them into a building filled with toys to meet the "master writer." They quickly discovered


it to be a trap as they had been locked away with Nimbus, a terrifying creature. With Cole's ghost abilities, the Ninja managed to escape and discovered that Fenwick was actually working for Morro.

The Ninja soon ran into Nobu who informed them where the Sword of Sanctuary was kept, though the Ninja arrived just after Morro claimed the sword. With it in hand, the ghost was able to escape from Cloud Kingdom though after an intense chase down the Wailing Alps, the Ninja emerged victor with the sword in possession.

The Crooked Path

When the Ninja are preparing Stepped Wisdom for a Ghost attack, Kai puts up a bucket of water on top of a door. After hearing a bell ring, Kai and the others hurled water balloons at the Postman, thinking he was a Ghost. The Postman then told them they're going out of business due to the lack of customers. They then decided not to tell Ronin so he can stay and help them.

When the Ninja were told to come in Steep Wisdom so Misako can explain the third clue, Kai asked Ronin what he's looking for, to which he said he was just sorting the tea blends. Misako and Wu told them about the three tests and that Kai reminded her earlier about a map at the back of the Scroll of Airjitzu and that the reflection on the sword just might tell them the location. They went outside to stop Ronin from stealing the sword, but was caught in the traps they had set up earlier. When they chased after him, they realized his ship was empty.

They later got a message from "Ronin" stating that the tomb was located in the Caves of Despair. They checked it out, and found the skull symbol at the entrance. They initially thought the lanterns they encountered were the first of three tests, but was proven otherwise when nothing happened. They encountered a Kethanol geyser and when Cle blocked it with a boulder, it erupted and they found themselves riding on minecarts. Before they could fall into a pit of lava, R.E.X., on autopilot, came by to save them. Ronin, on a message, said he'll let them borrow R.E.X. to travel to the real location of the tomb, under the ocean.

Grave Danger

Arriving at the tomb's entrance after nearly avoiding the Leviathan, and accidentally leaving their Aeroblades behind, the Ninja head inside and found themselves surrounded by sixteen doors, each with images on it. P.I.X.A.L. informed Zane they're in a zoetrope, and they have to use Spinjitzu to find the correct symbol. He did so, and they enter the door with the Yin-Yang symbol.

They entered the second test room, with Kai determined to reach the staff, activating most of the traps. Cole had the idea to jump down the hole they made, and after it works, he reluctantly followed suit.

Future Kai

Falling into the third test room, the Ninja, except Cole, saw their future in the wall's reflections. They spotted Morro, and Kai was able to trap him with stalactites. They solved the test by digging straight down and end up in the tomb.

Suddenly, Morro, who managed to escape Kai's trap, threatened to kill Lloyd if they don't give him the Crystal. The Ninja realized they have their powers back, but it's weak. Kai secretly burned the Crystal, Making Morro drop it into a nearby river. Lloyd attacked him, but Morro pushed him down the river, with Kai and Cole trying to save him. With Cole not being able to touch water, Kai dove in to save him, however, he was not able to grab the Crystal in time, resulting in Morro winning. When they got out of the tomb, Kai comforted Lloyd that they'll grow stronger as he recovers.

Curseworld, Part I

Kai and the rest of the Ninja went to Steep Wisdom to get vehicles Cyrus Borg built. Unfortunately, Kai only got a headband due to the lack of time. Kai suggests they use Nya as the key to get close to the Ghosts, to which she agrees.

Trying to distract the Ghosts, Kai poured tea on one of them, getting them to chase him. Eventually, he tries to stop Lloyd from listening to Morro when he's trying to destroy the Crystal but failed. The Ninja were forced to watch Lloyd get captured into the Cursed Realm.

Curseworld, Part II

Kai tried to weaken the Preeminent by using his Fire, but she didn't budge. When Cole was about to use his Ghost Cycle on the Preeminent, the Ninja kept shooting their powers at her to cover him.

Kai suggests they get closer to the Preeminent to save Lloyd, but it was no use. They have to go back to the ship. They see Lloyd come back, and had to destroy the stilts to drop the Preeminent into the sea, after which the Ghosts defended her with houses. He went closer to the Preeminent, allowing the Ninja to follow suite.

He fell into the water, but Zane told him to use his Fire on Soul Archer and together with his Ice, they were able to make water to defeat him. However, the Ghost respawned, much to their disappointment. They went back to the ship in order to defend its passengers. He watched as Nya destroy the Preeminent with her unlocked True Potential.



Following the defeat of the Preeminent, the Ninja rose in popularity and began being treated as celebrities. Kai in particular loved the attention. Following the discovery that Clouse had managed to escape the Cursed Realm, Kai and the other Ninja headed to Stiix to stop him, taking a brief detour to the hospital for Lil' Nelson's Grant-a-Wish.

Upon arriving in Stiix, the ninja were unable to locate Clouse and discovered to their horror that they had been framed for a crime free. Now wanted criminals, Kai and the other Ninja were forced to split up to avoid detection.

Public Enemy Number One

After a brief meeting with the other Ninja where they discovered that a Djinn might be behind their framing, Nya and Kai headed to Jamanakai Village where Nya had hid spare bikes. Upon receiving a distress call from Zane, the two headed to the Corridor of Elders, only to be ambushed and captured by Ronin, who had been paid to round up the wanted Ninja. Once all six of them had been captured, they were lead onto a bus bound for Kryptarium Prison.


Kai imprisoned with his friends

While at Kryptarium, Kai and the other Ninja learned from Captain Soto that this Djinn was none other than Nadakhan, a feared pirate captain whom Soto had trapped himself centuries ago. That night, as part of Lloyd's prison break plan, Kai found Soto and freed him from his cell in exchange for information on how to defeat the Djinn.

Misfortune Rising

While Cole and Lloyd tried to find the Misfortune's Keep, Kai and Zane were assigned to recover the Destiny's Bounty. However, after being attacked by the guard and his dog, the two of them were forced to flee.

Later, after regrouping with the other Ninja at Yang Tavern, they learned of Misfortune's Keep attack on Ninjago City and decided to come out of hiding to defend the innocent and retrieve Soto's lantern. During the battle, Kai and Jay were separated by an explosive barrel thrown by Monkey Wretch. Before Jay could catch up, Nadakhan transported the Red Ninja to Cannon Beach[citation needed] to trick him into using his three wishes.

In an attempt to escape, Kai wished to go back, only to be taken back in time to when his father was a humble blacksmith. After witnessing his father ask for his help, Kai, not wanting to mess with the timeline, demanded that Nadakhan return him back to a time when the latter wasn't present, when his fan girls still appreciated him, etc. Because of the high content of his wish, Nadakhan instead chose to focus on a single aspect, transporting Kai into an alternate reality where all of the psychotic fan girls began chasing him around. In desperation, the Red Ninja was goaded into wishing it all away, resulting in his imprisonment in the Djinn Blade. As a result, Nadakhan would use the power of his soul to begin tearing chunks out of Ninjago.

Operation Land Ho!

While trapped inside the Sword of Souls, Kai would be freed by Jay alongside the rest of his imprisoned allies, their release resulting in the defeat of several Sky Pirates converging on their position.

The Way Back

After thanking the members of Jay's new team, Kai went with the other Ninja to stop Nadakhan from marrying Nya. However, they failed to stop the ceremony and retreated before Nadakhan could capture them. Regrouping on the Misfortune's Keep with the now reformed Dogshank and Flintlocke, they discovered from Jay not only where Clancee kept the Tiger Widow venom but also the true reason behind the wishes Nadakhan granted: their inabilities was only interpretation on Nadakhan's part: in the end, Nadakhan's powers were limited in that he had to solely rely on his victims to accomplish his wishes, as the ability came from its rightful owner. With this, Flintlocke regained his aim and was declared the one to shoot Nadakhan with the venom while the others distract the Djinn.

The Ninja put the plan into action, though discover Nya has been possessed by the now-revived Delara. Although they evade most of the attacks, Nadakhan turns them into gold statues until only Jay is left. Flintlocke is soon able to take the shot, successfully hitting Nadakhan and his power begins to diminish: unfortunately, the venom also hit Nya, who soon dies in Jay's arms. Everyone is devastated, Kai having to be comforted by Zane while the weakened Nadakhan musters up his remaining strength, though it's in vain as Jay wishes from the heart that Nya had taken his hand and that Nadakhan was never freed.

Time soon reverses to when the ninja are on the roof of Ninjago City hospital with only Jay and Nya remembering all of the events. The two renew their relationship, which everyone is happy for, though Kai becomes disgusted from seeing his sister kiss Jay but eventually accepted it.

Dark Island Trilogy

Dark Island Trilogy, Part 1

Kai and the other Ninja were summoned to the Samurai X Cave by Master Wu, who informed them that Misako and Ronin had gone missing off the coast of the Dark Island. The Ninja quickly readied the Destiny's Bounty and they set off towards the island.

Upon nearing the island however, the Bounty encountered an unnatural storm that sent the Ninja falling from the sky. When Kai awoke, he found himself alone in the middle of a vast desert.

Dark Island Trilogy, Part 3

Day of the Departed

Using their new vehicles—including the components of the Ultra Stealth Raider—the Ninja traveled to the Ninjago Museum of History on the Day of the Departed in order to acquire lanterns for the celebration. After viewing the Hall of Villainy, the Ninja split up to pay their respective requests, inadvertently leaving Cole behind. Kai and Nya traveled back to Four Weapons Blacksmith in order to commemorate their parents, and Nya questioned whether they would ever learn what really became of them. Chen and two of his Anacondrai Cultists, revived by the dark magic of Master Yang, then arrived to attack the pair, but they were able to defeat the villains and destroy them. Returning to the museum, they found their friends and learned they went through similar experiences, wondering what the cause was before Wu and Morro arrive telling them it was Yang's plan.

Seeing Morro, Kai and the Ninja armed themselves as Jay question how many other ghosts there were left with Kai stating they've stopped several others and what's one more. He is surprised when Wu tells them that Morro was there to help and the latter tells them that Yang tricked Cole into opening a rift to return to Ninjago. The Ninja soon realized they forgot about Cole and Wu orders them to ready the Bounty and head for the Temple of Airjitzu while a redeemed Morro returns to the Departed Realm.

The Ninja used the Bounty to travel to Yang's floating Temple of Airjitzu, where they are caught in a powerful storm with wind blowing their ship around. However, their timely arrival gave Cole the drive needed to win and they watch as he overpowered Yang.

Kai and the others become confused by Cole speaking to Yang telling him he needed to pass through the Rift.

The Ninja watched as the Rift closes before getting caught in its shockwave, forcing them to make a crash landing on the ground of the floating Temple. Once they landed, they feared if Cole hadn't made it through the Rift in time but were overjoyed when he emerged from behind a rock, a human again. The Ninja happily hugged their friend, relieved to have him back to normal. Kai soon pointed out the restored Temple of Airjitzu and at Cole's suggestion, they make it their new base.

Later that night, they gathered around a fire with their families and friends listening to Cole's story before releasing lanterns into the sky in celebration.

The Hands of Time

The Hands of Time

When the Ninja clean up the museum, Kai told Nya about a picture he found of their parents. Later, they see another picture of Garmadon and Wu forty years ago and ask Dr. Saunders what it is.

When they're off, an energy displacement caused them to be relocated on the Bounty. P.I.X.A.L. told them the source is at the monastery, where Wu was, and the Ninja took off.

They eventually encountered Acronix and fought him. Afterward, they save Wu before he could fall off the mountain.

The Hatching

The Ninja asked Wu about their fight with Acronix. Afterward, they left him so he could rest. They discussed the painting they saw at the museum and how it relates to Wu's flashback.

After a while, the Ninja watched a news channel reporting a Vermillion Warrior wreaking havoc at the BorgStore. They decided to attack it one-on-one, but failed, noticing the Warrior could regenerate. Concluding that the Vermillion might try to kidnap Cyrus, the Ninja tried to help him. However, they found Zane unconscious and Cyrus Borg missing.

A Time of Traitors

Kai and Saunders

After failing to figure out what the Vermillion helmet does, they went to see Wu for answers. He was unable to answer, however, so Kai went to the museum while Lloyd stays with Wu, and Jay, Cole, and Nya went to the Samurai X Cave to reboot Zane.

When he got there, he asked Dr. Saunders about the helmet, and then decided to look around for anything useful. He discovered Dr. Saunders was Krux and a fight broke out between the two, when Acronix came Nya arrived to help and the siblings managed to temporarily defeat and escape the Time Twins.

Afterwards, they went back to the Cave and found Zane rebooting.


After Kai was distant from his previous encounter with Krux, he started to take his anger off on some Sparring Bots. He agreed to fight the Vermillion but was interrupted when Lloyd told them he will be their new Master. However, when Lloyd suggests they make a plan, they reluctantly agreed.

When Ronin and Dareth came to tell them the Vermillion are stealing metal, the Ninja left.

After a brief fight, the power went out and the Ninja met Lloyd at the power source. They created a magnet to attract the snakes' armor, rendering them vulnerable. The power went back on, and they heard the Vermillion are attacking Mega Monster Amusement Park. They left for the park, and Kai told Nya he needs to tell her something when it's over

A Line in the Sand

Kai fought the Vermillion at Mega Monster Amusement Park. When he sees a symbol on the Vermillion's helmet, he looks at it in astonishment. When he grouped up with the others, they realize they haven't seen Jay since they left for the amusement park.

When time slowed down, the Vermillion Warriors left the park. They figured another Time Blade has arrived, and Zae gave out its location. They left and try to get there before the Vermillion do.

Nearing the Time Blade, Raggmunk threw snakes at them to make them crash. When they tried to get it, Blunck shot them with the Time Blade, slowing them down.

The Army and Ninja were slowed down right when Jay came to save them. He managed to free everyone from the time bubble. They fought for the Blade and managed to escape with it.

The Attack

After closely examining the helmet, Kai states he's got a clue, but it turned out to be false and he continues to observe it.

When Wu told the Ninja to net let pride cloud their judgment, Kai asks Wu what the symbol meant and asked for everything he knew.

A moment later, they were attacked by Vermillion. They defeated them with Spinjitzu, and Kai asks Wu what the symbol meant. The snakes regenerated into Buffmillion, and Kai and Nya tripped it until it fell down the floating island.

Lloyd suggests they take out their weaponry by using their Dragons, but they don't think it's a good idea. Lloyd's Dragon disappears and Kai tries to save him but was held back by the Vermillion's sky team. Samurai X saved Lloyd but flew away before anyone could find out their identity.

Just as Wu was about to answer Kai's question, they were confronted by the twins. They eventually got both the Blades, but it was stolen by Machia when they least expected.

They mourned over their defeat and blamed their overconfidence.

Secrets Discovered

Nya and Kai at Skylors noodle house

Seeking counsel, Kai journeyed to Mr. Chen's Noodle Shop to speak with Skylor, as she had dealt with her father being a villain as well. Nya soon arrived and he presented the two helmets as evidence to her, though he was met with skepticism until he proved it to her. The siblings realized their father was still alive but couldn't bring themselves to accept he is working with the enemy. They were soon interrupted by a call from Lloyd, informing them that the other Ninja had discovered the secret base of the Hands of Time. As he and Nya set out, Kai realized that this meant they also knew where their parents were.

Pause and Effect

Kai entered the blacksmith's building and found his father Ray building weapons. Kai confronted him and attacked the latter as the latter defended himself. Kai then revealed his identity to his shocked father who tried to talk him down but he didn't listen to him nor his arriving sister. However, the voice is his mother Maya and he stops but still tells Nya she is guilty like their father. Their parents proceed to tell them the truth: Krux wanted revenge on them for building the Time Blades and threatened Kai and Nya if they didn't comply which is why they were separated. Hearing this, Kai felt guilty for accusing them as he sees they weren't at fault.

Out of the Fire and Into the Boiling Sea

When Kai refused to retrieve the Time Blade for the twins, Nya reminded him it's the only way to save Wu. Later, when Ray gave them the Dragon Blade to create the Fusion Dragon, Kai's impatience caused them to miss out on Ray's advice. Once inside, Nya creates a water slide to reach Hono Mizu.

When they reached the bottom, they were greeted by Geotomic Rock Monsters. When they used both their powers together, they realized they needed to work together. Once they reached a door, Nya figured out they open it with the Dragon Blade. When Kai took the Blade, however, the building starts to collapse. They used the Fusion Dragon to escape.

Once they returned, Kai was about to use the Time Blade on him but the twins said they lied about their promise. As they fought, Ray pushed Kai so he would be hit with the Time Punch instead. Acronix used the Pause Time Blade on everyone and they stole the Reversal Time Blade and left with the ship. When they let them fall into the Boiling Sea, Nya and Kai used the Fusion Dragon to save everyone.

They went to the Iron Doom, with Ray and Maya jumping off to increase speed. They followed the Iron Doom into the Temporal Vortex.

Lost in Time

Kai, with young Wu and Garmadon

As the Iron Doom traveled to the future, Krux complained to Acronix about going to the future. Acronix tells him that by going into the future, there would be no one who recognizes them, no Elemental Masters, and no Kai and Nya.

At that moment, however, the Hands of Time are confronted by Kai, Nya, and Wu. Kai taunts them for being wrong as the final battle between them begins, Acronix fights Nya and Wu while Krux fights Kai. After Nya leaves to help her brother in fighting Krux, they proceed to overwhelm until Acronix joins in to aid his brother.

As the Iron Doom began to pass by the present, Acronix and Krux were able to overwhelm Kai and his sister and were about to finish them off, but are stopped by Wu. As Acronix tells him there is nothing he can do, Wu then proceeds to rip out the Reversal Time Blade from the Time Apparatus, causing the Iron Doom to spin out of control. Kai and Nya fall as Wu gives them the Reversal Time Blade before they returned to the present so that they can cure their father of the time punch. Wu stayed behind confronts a defeated Acronix and Krux, saying that it indeed ends now. As the three fought, the Iron Doom became lost in time with them still aboard as it traveled far into the future.

Though happy at their victory, Kai couldn't help but be worried when his master was feared to be lost in time with their enemies. He and the rest Ninja elect Lloyd as their master and he makes his first order to bury the reversal time blade and to discover what happened to Wu.

After The Hands of Time

Following Lloyd's request, Nya and Kai returned the Reversal Time Blade to the Boiling Sea for safekeeping.[7]

Kai was paired with Zane when the group split up to cover more ground in their search for Wu. At one point, the two hired Ronin to take them to the Tomb of the First Spinjitzu Master in their search.[8]

School for Crooks

At Chen's Noodle House, Kai got a message from Zane that a new criminal gang was recruiting members. Kai told this to Skylor, who thought back to a recent encounter with a few guys in her restaurant who had mentioned the "School for Crooks." Though Kai was planning on investigating with Zane, Skylor convinced the Master of Fire to team up with her for old times' sake.

That evening, Skylor and Kai went to the docks, where they spotted and gave chase to the cloaked figure who seemed to be the leader of the criminal school. At one point during the chase, Kai used Airjitzu, a technique Skylor had not seen before, to bring himself and Skylor closer to the unknown individual.

The two finally cornered the stranger, only for him to reveal himself as Ronin. Ronin explained that the "School for Crooks" was in fact a criminal reform course, and the gang Kai had heard about was something else entirely. Skylor and Kai bid farewell to Ronin as he mentioned his appreciation for the Noodle House's Puffy Potstickers.

Sons of Garmadon

The Mask of Deception

While Kai and Zane fought the Mechanic, P.I.X.A.L. asked them to meet with Lloyd. Zane eventually defeated him with Ice, but accidentally froze Kai in the process.

The Ninja regrouped, and Lloyd showed them the Sons of Garmadon logo and said they stole a mask. Hutchins informed them of the Oni Masks and that the Emperor of Ninjago will have a speech. The Ninja agreed to defend the mask during his speech.

During the speech, firecrackers went off, causing the audience to panic. The Royal Family is grateful they tried to save them and they were invited inside the palace.

The Royal Family informed the Ninja as long as they have the Oni Mask, their lives are in danger. The Ninja accepted the challenge to keep them safe and were given a tour with Hutchins.

When Hutchins showed them the Oni Mask of Deception, the Ninja agreed to protect it. Kai and Nya went onto the roof and saw Hutchins suspiciously walking away from the palace. When he noticed them, he walked back inside.

The Jade Princess

While training, the Ninja gave Lloyd some advice on how to attract Harumi, but Lloyd agreed with Nya to just be himself.

While helping guard the palace, Kai informed the Postman no one's allowed in the palace and that he can deliver the mail.

When the palace exploded, the Ninja fought the Sons of Garmadon. Later, Lloyd and Harumi picked them up on the Destiny's Bounty and informed them the Emperor, Empress, and Hutchins didn't survive.

The Oni and the Dragon

When Lloyd and Jay came back from Mistaké's shop, they watched Cole karaoke at Laughy's on television. Cole was attacked by the Sons of Garmadon and when Zane didn't help, the Ninja went to help him. While they were chasing Mr. E, Lloyd realized Zane was trying to gain their trust.

Snake Jaguar

When Lloyd was unable to find Zane or Cole, Jay and Kai checked the other stations.

Dead Man's Squall

After the Ninja found Zane shut off at the bottom of a cliff, they took him back to the Bounty. They then decided to leave Ninjago since the baby is the key to the Mask of Hatred.

When P.I.X.A.L. then informed the Ninja Mr. E told the Quiet One "The trap has been set." She told the Ninja she's trying to find the location of the Quiet One, but Cole showed them the baby's blanket with the map to the third Oni Mask on it.

When P.I.X.A.L., controlled by the Quiet One, shot one of the thrusters, the Ninja fought her. Just when she went back to normal, her destroyed another, causing the Bounty to fall. Nya was able to control the rain to slow down their fall, but the Bounty was damaged.

The Quiet One

As they tried to fix the Bounty, the baby, who had a growth spurt, hands Jay a pair of pliers, surprising Kai and the others. Kai is shocked to see the baby drink tea, before the child said their motto: "Ninja never quit," after Jay stated he quitted. This makes them realize the baby is a regressed Master Wu, which shocks them.

The Ninja tell Nya the things the baby did and how they discovered he is Wu, she doesn't believe them until she hears the baby talk. Afterwards, questions are raised by how Wu reverted to a toddler; Nya brings up Wu being touched by the Reversal Blade before he was lost in time. Kai questions his sister who states that it could of caused him to de-age. Kai listens as Zane states if Nya is correct, the blades' effects have worn off and now Wu will keep aging until he returns to normal, eventually.

The Ninja later discover Harumi is the Quiet One as the Sons of Garmadon attacked and surrounded them.

Game of Masks

Kai, fighting Harumi

The Ninja, now tied up in chains, try to convince the Sons of Garmadon not to resurrect Lord Garmadon, to no avail. When Killow calls for Ultra Violet, Wu hands them the keys and they start to confront the Sons of Garmadon.

During their standoff, they were reunited with Lloyd and Crabby attacked. The Sons of Garmadon leave on the Bounty and Lloyd followed them after they froze Crabby in ice. They were shocked when Lloyd was captured and Crabby started to break free.

Dread on Arrival

After the Ninja tamed Crabby, they rode it to the police station. They told the Commissioner the Sons of Garmadon are going to resurrect Lord Garmadon and need reinforcement.

While the police attack the Sons of Garmadon, the Ninja traverse to the Temple of Resurrection. They defeated the Sons of Garmadon and rescue Lloyd and Misako. They helped as the police arrested the Sons of Garmadon.

True Potential

To celebrate, the Ninja went to Laughy's to karaoke. However, the music was cut off and they watch the news about Garmadon breaking Harumi free from jail.

The Ninja went to the police station to question the Commissioner. The Commissioner confirmed he was Garmadon They watched the news again and realized Harumi and Garmadon are at Kryptarium Prison.

On the Bounty, the Ninja told Lloyd not to face his father. They later were tricked by the Green Ninja, who locked them in a room so he can go it alone.

When the Sons of Garmadon broadcasted Lloyd's fight with Garmadon, the Ninja are forced to watch.

Big Trouble, Little Ninjago

The Ninja went to Mistaké's tea shop in order to help Lloyd recover. However, they could lose their Elemental Powers. After thinking, he changed his mind and they all decided to help Lloyd.

They still have their Elemental Powers and Mistaké gave them tea in a bag. When the shop rumbles, they go outside to see Ninjago's citizens panicking. Nya stays with Lloyd while the other Ninja and P.I.X.A.L. go see what it is. They found Colossus and started attacking, but were forced to hide. P.I.X.A.L. decided to distract it while the Ninja run away.

The Ninja tried to pick up Lloyd on the Bounty but instead, they only got Wu. Before the Colossus could destroy the Bounty, they used the tea Mistaké gave them, which turned out to be Traveler's Tea. They woke up in the Realm of Oni and Dragons.



Marooned in the Realm of Oni and Dragons, the ninja spend a full week in the realm trying to gather supplies. Kai is the most worked up over the situation, as seen when he criticizes Jay for not freaking out and states him being calm is unsettling to him. Kai and Zane spend most of their time building a radio in the hopes of communicating with the realm of Ninjago.

As Kai and Zane listen on the makeshift radio, they see that Jay has completely lost his grip on reality as he plays on his homemade game, which is really a piece of wood. After Zane tells them he has intercepted a transmission, they believe it's from Ninjago, however, the people on the other side state they are preparing something. Kai doesn't understand some phrases they use and Zane translates the words to him by stating that they are talking about an ambush. Hearing this, Kai realizes they are talking about them and tells the others to run away.

As the trio run, Kai makes sure to keep a lookout for the attackers before figures in the fog quickly grab each of the Ninja in chains and drag them off.

Kai blindfolded and chained.

Held captive, Kai and his friends are brought chained and blindfolded into a settlement known as Dead's End by their captors who are known as the Dragon Hunters. As they are taken inside the throne room, Kai, trying to see through his blindfold, hears Jay wonder aloud if they are playing hide and seek (blindfolded) before halting in their footsteps. Kai is then slightly shoved by one of the Hunters dragging them. He responds by angrily struggling against them, but to no avail, before the trio are pushed to their knees, with Zane telling the two to be careful and not to provoke them. Three Hunters then remove their blindfolds individually for them to meet the Iron Baron, who taunts their situation before laughing with his fellow Hunters.

Iron & Stone

Kai and the others face a dragon

As they are held captive, Kai sees the Baron's throne (made from bones of the Ultra Dragon) and states he already hates him. When they were questioned over who else was with them, Zane tries to deny it, but Jet Jack shows them one of Wu's diapers. Kai spoke up by trying to pass them off as being Jay's as he tried to lie, saying he has a weak bladder, but they don't believe them. Iron Baron accuses them of being Oni while ignoring Kai's protests.

The captured Ninja are taken into The Pit which Jay notes is an arena where they will be attacked by something. Kai and Zane note that Jay is still not in his right mind and is useless in their plight. They find they are to fight a Dragon and are told by a hunter named Chew Toy to play dead.

During the fight, Kai goes through with playing dead and the Dragon, Slab, smells him but doesn't attack. Cole and Wu get their attention and use a lever to put a chain for them to trap the Dragon. Kai then alerts Jay that the Dragon would attack him but Zane freezes it, exposing their Elemental Power to all. Iron Baron realizes his mistake of thinking they were Oni and sees they are elemental masters. He then orders his followers to hunt them as Kai tells his friends to prepare for a brawl as the Hunters surround them.

Radio Free Ninjago

Kai, Jay, and Zane are cornered by the Dragon Hunters and have no choice but to use their Elemental Power. Kai does an estimate on the foes before Zane corrects him on the exact number and he states Zane was better at counting. Kai asks Jay if he's all right, as Jay lists all of the events that have befallen him and has a breakdown; this display causes Zane to note to Kai that he is back to normal, which relieves him.

They use their Elemental Power to fend off the Hunters when Heavy Metal jumps down with the Dragonbone Blade. They try to use their power on him, but as Zane points out, the blade attracts their Elemental Power. Now unable to use their power, they are chained up by Heavy Metal and put in the back of the Dieselnaut.

Held in place by the Hunters with Vengestone, Iron Baron approaches them and admits his surprise at them not being Oni, but trained in the ways of the First Spinjitzu Master. Kai is shocked by his familiarity and asks if he knew him as Baron states he knows his legends and calls him the coward who ran away to Ninjago. Kai then asks if he knows how to get them back, to which Baron responds no, but he had no interest in helping them any way. He then declares they are hunting Dragons and hopes that the catch he makes will be good.

He then turns on the machine and it releases strange energy that triggers an elemental reaction and the Ninja are subjected to a device that draws out their Elemental Power. Jay realizes that the Hunters are using them as bait since their powers attract the Dragons while noting it tickles.

Soon after, a Wind Dragon is attracted to the Ninja. Meanwhile, Cole and Wu (who are disguised as Hunters) "accidentally" knock the other Ninja off the stand. They try to rescue them, but the Ninja are immediately put back into the back of the Dieselnaut by Daddy No Legs.

Now in the back of the vehicle, they are forced to sit back and watch as the Hunters reel in and eventually capture the Wind Dragon.

Cole promises to figure a way out of this situation for them, and the Dragons.

How to Build a Dragon

As he and his friends are caged by the Hunters, Kai sleeps before Jay wakes him up by telling him and Zane that he heard Lloyd's voice on the Hunters' radio. Kai questioned him if he has lost it again but after he explains they see he is still sane.

As the Ninja are forced to work, they wonder about what to do as Jay suggests building a Dragon and they call it out foolish but he tells them of his plan to trick Baron into thinking the Firstbourne was attacking so they and the Dragons can escape. The Ninja like his plan and get to work by secretly gathering supplies.

Later on, the Ninja are put to work by the Iron Baron, and Jay draws the blueprint for the fake dragon in hidden. While Kai and the others assemble parts and send them off to Cole and Wu, the two of them assemble the Dragon away from the camp.

Soon after, at night, Iron Baron gets ready to cook the Wind Dragon, and Kai and the others wait for Cole and Wu to "attack" the base with their creation. They are tied up and watch the skies, and then finally, with Wu controlling it, the fake dragon appears over the camp, and Zane and the others act like it is the real thing which spooks the Hunters.

While the Hunters scramble to their stations to capture it, Cole maneuvers to the others and frees them from their chains. They make their way out, and at the same time, Wu is shot out of the sky. At first, the Ninja don't see it, and see the real Firstbourne in the sky and mistake it for Wu. When they realize it's the real thing, they freak out and attempt to flee.

Wu stops them and tells them that she is there to protect her Wind Dragon, but the Ninja assisted in capturing it. The only way for them to get out would be to save the Wind Dragon.

Kai and the Wind Dragon

Kai and the others make their way to the Dragon, who is tied up, and get caught in a fight with the Dragon Hunters. Kai breaks off from the fight and frees the Wind Dragon. It helps the Ninja fend off the Hunters, and the Ninja also help the other imprisoned Dragons escape.

Kai and the Ninja flee the scene, and Iron Baron says they are going hunting again...for the Ninja.

The Gilded Path

The Ninja found a camp spot and sat around the fire before Wu woke up and they see that he has aged again and become a teenager overnight. When Jay commented it was bad, Kai mentioned they were teenagers and Jay called them "grown-up" teenagers.

Heavy Metal then finds the Ninjas' camp and makes her presence known, Heavy Metal threatens the Ninja with her weapon telling them they are her prisoners now before interrogating them on Wu truly being the son of the First Spinjitzu Master. Kai tells Wu not to reveal his heritage since it might be dangerous like their power but Metal fires an arrow at Cole after stating they heard Kai's mumbling. Kai watched as Wu revealed himself and Metal revealing themselves to be a woman named Faith who is on their side.

The Ninja haul the vehicle while Faith tells the legend of the First Spinjitzu Master. They were then approached by Daddy No Legs and Muzzle. They were able to tie them up and steal their vehicles to continue their mission.

Two Lies, One Truth

When fighting over water with Kai, Faith slices a cactus in half so they could have enough. While they fight over the cactus, the Dragon Hunters caught up to them and they rode off. They made it to the canyons and managed to defeat them, but are unaware Jet Jack attached a tracking device on their vehicle.

The Ninja reached Oni territory and went in to look for the armor. They see the land was abandoned but noticed the gates reveal a map to the Dragon Armor, which is located in Firstbourne's nest.

The Weakest Link

When the Ninja woke up, Faith handed them chain guns. Kai and the others are taught by her to use them to survive against the Dragons, which excites Kai.

Kai is tasked by Faith to demonstrate "catching" a rock to practice, and he fails as she realizes they all need some help. Kai says the first person to catch the rock wins.

While the other Ninja have a hard time using their chains, Zane gets it on the first try. He asks if he won, and Jay says they thought he was the judge. Wu joins the others in trying to successfully wrap their chain around the rock, and when the others get it except him, he gets frustrated. Kai gives him some confidence, and he returns to the others and wraps the chain around the rock.

A few moments later, they see the Stormbringer flying above them, and they attempt to prove themselves by catching their first Dragon. Zane and the others hold her with the chains, and Wu hops on top of her and rides her for a moment before she knocks him off.

Later on, Faith tells them that to get to the Armor, they must get past the mountain in front of them. They hear the other Dragon Hunters behind them and realize they were being tracked. They fly through the caves of the mountain while they're chased, and Iron Baron finds out that Wu is the son of the First Spinjitzu Master. He tells his Hunters to not go after Faith, but Wu instead. They all get through the cave, with some of Hunter's men being left behind, and the Ninja realize there's no way to stop the Hunters unless they take Dieselnaut.

The Ninja dealt with the attack of Hunters and were soon able to hijack the Dieselnaut and escape but at the cost of Faith, who was captured by Baron.

Saving Faith

At Wu's pleas, the Ninja go to rescue Faith from the Hunters. She berates them and warns them it was a trap but the Dragon Hunters appear and capture them.

Kai is later tied to a stand with Cole and Zane, Kai shares banter with the others to keep their spirits up. He explains to Wu why this is important and they share a laugh. He watches as Faith tells the other Hunters that Iron Baron lied to them about the Oni who have been gone from the realm for centuries and tells them that he possibly killed the Hunters to get Dragonbone Blade. After Iron Baron silences any growing rebellion by threatening them, an annoyed Baron hushes his prisoners by turning on the elemental device.

However, torture causes Wu to regain all of his memories and slightly aged further into an older teenager. Kai watches as Wu breaks free of his bonds and begins to fight Wu with the Dragon Hunters but is knocked aside. He watches as Iron Baron negotiates with Wu who accepts the offer of leading him to the armor to return to Ninjago. Kai, Faith, and the Ninja tell him not to help Baron but he tells them to believe in him.

Kai is left to watch as Wu and Baron leave the area in search of the armor.

Lessons for a Master

Kai and the others were still stuck on the wooden stakes. Above them, two vulture-like birds fly above them, and Kai asks if they are Zane's falcon. However, Zane remarks that his data picks up that they are a group of avian scavengers, that will pick them apart upon their demise. Faith confirms this, and Jay freaks out.

They notice that the other Hunters are arguing down below. While they're distracted, they try to rock their bodies side to side in order to knock the stakes over. The rocking seems to be working, and they cheer. As they do, Jet Jack asks them what they're doing, and she cuts them down.

After the Ninja are freed, they are skeptical of the Hunters' intentions and Kai tells them if they plan on eating them to eat Cole first since he is filled with cake as his friends are shocked by this. However, the Hunters reveal they want the Ninja to defeat Baron as they see Baron was only using them and will become even more dangerous with the armor.

They arrive at a bridge that leads to the armor and find that it's too late, as the bridge has fallen.

Kai and the others congratulate Wu on claiming the Dragon Armor.

Kai and the others return from the bridge to give the bad news to the other Hunters, and just then, Wu rides back the Firstbourne out of the nest without any chains and discovers the Ninja, Faith, and the other Dragon Hunters, who had since turned on Baron in his absence and freed the Ninja.

As soon as he lands, he reveals Iron Baron's fate. The Ninja bow to him as Dragon Master, but Wu claims that it is he who should bow to them, as it was they who taught him everything since they arrived in the realm. Kai watches as Cole points out that their job isn't finished, Wu asks the Firstbourne if she will get him and his former students home. She agrees to do so, calling upon four other Dragons for the Ninja to ride. Kai gains a new Fire Dragon and is amazed at it.

With their work finally finished in the Realm of Oni and Dragons, Kai and the others ride the Dragons out of the realm and begin their return to Ninjago.

Green Destiny

Returning to Ninjago, Kai flies on his dragon.

Arriving in Ninjago through a portal forming in the air, Kai and the others are devastated by the city's state and start to look for their friends. They don't have to search for long as Nya contacts Kai and he is happy to hear his sister's voice and they make it in time to save them from Ultra Violet and her lackeys who flee after seeing the dragons. Kai then reunites with his other friends who are happy that he and the others are back however, Kai sees Skylor and learns from Lloyd that she was poisoned by Garmadon's power.

The Ninja continue fighting against the Colossus, using Vengestone Harpoons to try and incapacitate it. However, the chains are ineffective, and they eventually run out of them. Kai jumps onto the Colossus and begins binding the chains together even tighter.

The Ninja soon run out of chains and wonder what to do, before the Firstbourne returns and Wu fires his chain gun at the behemoth. The tides continues to turn in the Ninja's favor, as their allies escape the prison and return to the city to help defeat the Colossus. Very soon, the Ninja and their allies incapacitate the Colossus using the chains, and it falls to the ground. Once Garmadon loses his power, the Colossus crumbles apart and the ninja are victorious. In Nya's armored van, Kai tends to Skylor who wakes up after her health is restored, assuring her they have won the battle.

They then have the Sons of Garmadon arrested before Lloyd arrives with his defeated father and the ninja celebrate his restored power while Garmadon is arrested.

Several days later, the Ninja clean up the Royal Palace and complain since they saved the city before Wu (an old man again) tells them there's trouble.

Kai and Skylor become a couple

The Ninja run out of the palace and find a crowd celebrating their victory. During this time, Kai and Skylor hug before becoming a couple.

March of the Oni

The Darkness Comes

Kai helped Jay practice how to ask Nya to be his Yang but after showing him how to act with confidence, Jay dismissed the idea. Afterwards, Dareth comes in and Kai told him to keep it a secret. Nya also comes in to show them her new kimono and they all went outside to look at the new murals with Wu. Suddenly, they saw Firstbourne crash and landed near the mountain. They ran to her and saw Faith was also badly injured. They brought her inside the monastery to help her heal.

Faith mentioned that darkness swept over her home realm and that she barely escaped. Wu points out it might be the Oni and the Ninja head to the Bounty to prepare.

When they arrived at the city, the Ninja rescued the people. They tried to fight the darkness with their powers, but it had no effect. They retreated back on the Bounty and Lloyd told them Garmadon might be able to defeat the Oni. They went to Kryptarium to release him.

Into the Breach

Once the Ninja are airborne again, the Ninja discussed if they could trust Garmadon. Meanwhile, he turned the engines off, and the Bounty starts plummeting toward the ground. The Ninja hanged on until Zane got to the ignition switch in the nick of time.

While Lloyd followed Garmadon to the cabinet, Kai told Jay he should ask Nya to be his Yang as soon as possible. Cole joins in and tells him the same, but Zane told them they were needed on the bridge. Garmadon proceeds to tell the Ninja about how the Oni were able to enter Ninjago. They used the Realm Crystal and he would be able to go inside the dark cloud to destroy it due to being part Oni, but he would need a weapon. Lloyd then argues that they can't just let him have a weapon then let him walk away unsupervised. Since Lloyd is part Oni as well, he claimed would also survive the darkness and decided to go with him.

When they arrived at Borg Tower, the Ninja handed Garmadon a sword, but he started attacking them to activate his powers. He jumped off, and Lloyd followed. After watching Lloyd on his head cam, they heard distress calls and tried to find the source. They flew off, while P.I.X.A.L. decided to stay behind in case the two needed assistance.

While trying to find the source, the Ninja watched as Lloyd and Garmadon approaches the Crystal. When The Omega attacked them, his head cam broke.

The Fall

Kai and Nya

The Ninja found the source of the distress signal at the NGTV building. Jay and Cole went out to help the people, but once they were about to leave, Nya accidentally turned the thrusters the wrong way. This caused Cole's rope ladder to snap as the Ninja watched him fall. Kai tried to turn the ship around, but Zane convinced him otherwise.

They went to save P.I.X.A.L., Lloyd, and Garmadon as they ran out of fuel. The Ninja told them Cole fell off the Bounty, and Nya blames herself despite Jay and Kai saying it was an accident. After Garmadon told them they are wasting time mourning, he showed them the Golden Master's armor. However, everyone was upset at him and started leaving.

Nya still blamed herself while Kai tried to reassure her by telling her she's the one that makes plans for the Ninja. She then said they can go back to the Monastery of Spinjitzu to forge the armor's metal back into weapons. Despite Kai being hesitant, he agreed.


The Ninja landed near the monastery and Wu and Misako went to see them. They told the two that Cole fell into the dark clouds and destroying the Realm Crystal did nothing. However, Garmadon showed them the Golden Armor and Nya explained they might have a chance if they reforge the Golden Weapons. After Kai was done, he gave the weapons to their respective Ninja, but had to give the Scythe of Quakes to Nya. A monk then signals to the Ninja that the Oni are here, and they prepare to fight.

The Ninja began the fight them and were surprised to see Cole arrived. Nya then hands him his Scythe but they were overpowered and retreated into the monastery. They then watched as Jay asked Nya to be his Yang, to which she accepts. Lloyd then points out that they can try using the Tornado of Creation against the Oni.

However, they found Lloyd under a pile of debris and mourned. He suddenly woke up and the Ninja were relieved. As celebration, their allies visited the monastery and watched the Ninja make a new mural with their handprints.

Secrets of the Forbidden Spinjitzu

Wasted True Potential

The Ninja, (Except for Jay and Zane) watch as Cole beats Zane's high score in a game called Lava Zombies. The Ninja sit in the hot tub, which turns out to be the Bell of Divinity. Infuriated, Wu puts the Ninja to a test to see how long they can survive in the room with his chicken. They were able to trap the chicken, but Wu was unimpressed.

After complaining about the traps Wu set up, the Ninja asked him what to do. He challenged them to a battle, but they were easily defeated. Once again, the chicken was released to punish them.

Questing for Quests

Kai is tired of thinking of a quest, so Jay suggests the hot tub. The Ninja ponders over which villain to battle. Kai suggests Killow, but he is in Kryptarium Prison with his former colleague, Ultra Violet. After realizing that they should help the Police Commissioner with the police, they find nothing good to do, so they return to the Monastery to find a news article about a far off desert in Ninjago with a pyramid that needed exploring. They quickly left for the Desert of Doom.

A Rocky Start

The Ninja are scrambling around the Monastery trying to get ready to go investigate the Desert of Doom.

Once they’re all packed, P.I.X.A.L. shows them to the Hangar Bay, where she has made several new vehicles for the Ninja, including the Land Bounty. Kai and Cole take their vehicles to the Desert while Zane, Jay, Nya, and Lloyd board the Land Bounty, while.

When they finally arrive, they set up a camp around an oasis they have found. Zane reads a book about the Desert, telling them that long ago, an ancient tribe once lived in the Desert. They worshipped a thousand-year-old giant scarab beetle called Beohernie. One day, the beetle went out of control, and destroyed the civilization, seemingly for no reason. The beetle suddenly appears and attacks, and the Ninja make a run for it to the Bounty.

As the beetle chases them, Cole is knocked over and is almost left behind. He recuperates himself, and the Ninja are continued to be chased by the giant.

While making a run for it, a major component to the Land Bounty is devoured by the Beetle, and the Ninja are left stranded on a plateau, surrounded by two more scarab beetles.

The Belly of the Beast

Kai and the others are trapped while Zane attempts to repair the Land Bounty, but it will be impossible to escape without the component the beetle ate.

That night, Kai hears Zane says that the Bounty is useless without the component, and the only way to retrieve it is to go to the belly of the beast itself. He then gets the idea that one of them has to be strapped to a rope and sent into the stomach of the beetle. They play a rock-paper-clamp tournament to decide who goes in, and Zane ends up being the winner.

The next morning, Zane goes on the sand and is consumed by Beohernie. When Zane notifies the Ninja that he found the component, the Ninja pull him from Beohernie, but he resists by pulling onto Cole's Dirt Bike. The force by Beohernie causes Cole to fall out of his vehicle and onto the sand where two more bugs begin to attack, but they are repelled by the Ninja. Eventually, Kai shot fireballs at Beohernie's belly, which allowed Zane to escape the belly of the beast.

With the component recovered, the Ninja were to escape the rock and outrun the other scarab beetles to their next destination, the Ancient Pyramid.

Boobytraps and How to Survive Them

Kai and the others meet up with Clutch Powers in his camp in the Desert of Doom. Clutch refuses to enter the temple. The Ninja tries to convince him, but he is unwilling. Zane points out that his book, Booby Traps and How to Survive Them, is key in helping explorers enter ancient tombs and whatnot. Clutch suddenly gets a call from the Explorers Club, saying that since he hasn't explored in over 10 years, his membership will be redacted. To preserve his place in the Club, he tells him that he will now be exploring the ancient pyramid.

Clutch and the others enter the Pyramid and find that it is filled with booby traps and ancient markings. He tells them that his book is key in surviving. Their first obstacle is a rickety old wooden bridge. Zane and the others stumble across, but they survive without trouble. Clutch tells them they got lucky, but luck runs out.

As they continue through, they trip over a trap that sends them all sliding down a corridor to a pit of spikes. Kai blasts the spikes with his fire, securing their lives. At the bottom of the pit, they find a pathway to the next room.

Finally, they find the main chamber, where several sarcophagi are lined out. In the next room, they find a large puzzle on the wall, and Zane points out that when solved, might lead them to a treasure behind the door.

While Jay and Nya attempt to solve it, Zane inspects the ancient markings on the walls. He translates the writing, which is a warning to those attempting to enter the tomb. It tells the story of a serpent whose anger almost destroyed Ninjago until a foolish boy locked her away. He suddenly has a vision of his dream with Aspheera and warns the others not to open the door. He is too late, and the sorceress is awakened. Her name is Aspheera. She tells the Ninja where Is the "Treacherous deceiver" but the Ninja doesn't know who she is talking about and attempt Zane and the others attempt to fight her with Spinjitzu, but she too knows the art, and so they are unable to stop her.

Kai, having his powers drained

She takes an interest in Kai, calling him a Fire Elemental, and tells him that for thousands of years she has been locked up, cold, and alone. She starts to steal his power from him, and the others are no match for her, and she successfully steals his powers and becomes empowered by fire. Kai is left unconscious after his powers are taken.

Clutch runs away as the Ninja are tied up in chains by Aspheera and escapes.

Ninja vs Lava

When the Ninja escape the Ancient Pyramid, they are forced to drag an unconscious Kai who hits several objects along the way.

When Kai wakes up, he talks about his jaw hurting although the guilty Ninja don't admit what happened. They then meet up with P.I.X.A.L. who gives them a ride to Ninjago City to stop Aspheera.


Before Fred Finely is devoured by an Elemental Cobra, the Ninja save him and defeat the Elemental Cobra before heading off to the Ninjago Museum of History.


Kai and Jake

Along the way, the Ninja save the Police Commissioner and his crew, but Kai was unable to help because his elemental power was stripped from Aspheera forcing Jay to save him from two Elemental Cobras. Before the Ninja headed off to the Museum, Kai said he felt useless and refused to go.

When the Ninja leave Kai, Jake came running into him and asks for his autograph; however, Kai tells Jake that the Ninja who did all the work. When the young boy asked why Kai isn't helping the Ninja, he tells Jake that he is without powers. This makes Jake upset and he calls Kai a quitter. This makes Jake chase after the Ninja and decided he will help the Ninja.

Just before the Ninja were defeated by the Elemental Cobras, Jake came running in to shield the Ninja from harm, despite having no weapons to defend himself. A moment later, Kai saved Jake while defeating the Elemental Cobras.

After Kai saved the Ninja, they celebrate and Jake is glad that Kai helped the Ninja although he lost his Elemental Powers. Moreover, Kai calls Jake a hero for being so brave.

Ancient History

Cole, Kai, and Jay head down the sewer to find Skales, but instead, find three Hypnobrai and are taken captive. When they are taken to Skales, he is unhappy to see them although he helps them find information on Aspheera with the help of Acidicus.

After finding who the "Treacherous Deceiver" is, they head back to the Monastery to tell Wu that Aspheera is out for Garmadon, but Wu tells them that she is out for him, not his brother.

Never Trust a Human

Kai listened to Wu as he gives his story on how he became the "Treacherous Deceiver."

Under Siege

Kai forgiving Wu

After Wu tells the story, Cole, Jay, Kai, and P.I.X.A.L. ask questions, but before Wu could answer all of them, they here noise outside and realize Aspheera is on her way. Cole asks about the second Scroll of Forbidden Spinjitzu and using logic, P.I.X.A.L. thought the second scroll would be with an archeologist, so he contacts Lloyd, Zane, and Nya to find Clutch Powers.

P.I.X.A.L. activates the defensive systems for the Monastery, but Aspheera banishes them and Fire Fang obliterates the door causing them to retreat to the Hangar Bay. When they realize they cannot escape, Kai blames Wu for their troubles, and Cole tries to comfort him, but he walks away.

When the Pyro Vipers find out their secret hideout, Wu believes he should face them alone, but Kai apologizes to Wu and promises they will face Aspheera as a team.

The Explorers Club

Kai continues to work on the Titan Mech along with Jay and P.I.X.A.L.

Vengeance is Mine!

The Pyro Vipers break the door to the Hangar Bay, but they are unable to find Wu until Jays gives away their hideout by sneezing. Before Aspheera could do any harm, P.I.X.A.L. uses the Titan Mech to defend the Ninja and Wu. Despite this, Aspheera manages to hold her ground and holds the Ninja hostage until Lloyd, Nya, and Zane arrive with the second Scroll of Forbidden Spinjitzu.

A lengthy battle ensues with Kai having the chance to possess the Scroll when it falls into his hands, but without his Elemental Power, the Scroll didn't work and he was knocked down by Aspheera. Eventually, Zane gets the Scroll and freezes the Pyro Vipers. Before Zane gave back the Scroll to Wu, Aspheera's arm manages to get free and she attempts to zap Wu, but Zane saved his master by pushing Wu of the way causing him to be hit and be seemingly destroyed.

A Cold Goodbye

The Ninja come running in after P.I.X.A.L. has a nightmare of losing Zane. Wu then tells the Ninja that Zane is alive; however, Wu won't let the Ninja come since its location is remote.

Despite this, Lloyd steals the Traveler's Tea and the Ninja head to the Hangar Bay where they spot Wu holding the Scroll of Forbidden Spinjitzu. A lengthy battle occurs as both sides were fighting for the Traveler's Tea. This gave the Ninja no choice, but to tie Wu up and place a mouthpiece over him. In the end, the Ninja headed inside the Land Bounty while P.I.X.A.L. stood outside and zapped the vehicle into the Never-Realm.

The Never-Realm

The Land Bounty lands on a cliff, forcing the Ninja to evacuate and during the process, Cole loses the Traveler's Tea. This causes an argument with Jay before Lloyd breaks up the fight and suggests they head down the mountain to avoid freezing.

After hiking through frigid temperatures, the Ninja finally arrive at a forest where it’s still cold. Also, the Ninja face danger when they are approached by wolves. The Ninja flee from the danger, but Lloyd runs into a tree giving a chance for the wolves to attack but despite that, the wolves head off somewhere else. What the Ninja don’t realize is that one of the wolves is frozen on a tree.

Following the unusual sight of wolves running away, the Ninja stumble upon some people who are also frozen. Nya quickly senses one of the victims realizing they have a heartbeat and are still alive, but Nya also gets a signal on the Titan Mech. Before they sought out to find the Mech, Jay believed they should help the people, but Lloyd and Nya stand their ground saying they should get more information before assisting the people.

After following the bleak signal for some time, the Ninja run into the wolves again, but this time they fight. They manage to hold their ground for some time until three mysterious people shoot arrows at the wolves causing them to run away. 

The Ninja follow the people to a nearby village where they are greeted by the elder Sorla. After both sides give their introductions, Sorla throws a potion into the hearth fire, and they find Zane's location which is the Ice Emperor's Castle. Sorla tells them that Zane was most likely taken captive by the Ice Emperor and he is "lost." However, Lloyd believes that Zane is strong and they will still come for him despite all the dangers she said. Sorla then warns them of General Vex who would surely be out to get the Ninja. 

Fire Maker

Kai regaining his powers

Kai along with Jay try on new gear that will help them walk through the snow.

Inside their base, the Ice Fishers throw ideas around on what they should do, but disagreements arise. Sorla then states that can't leave the Fire and they must protect it. When Kai asks if they can light another Fire, he is met by criticism by the Ice Fishers, but Sorla explains that they can't light another Fire since the weather is too cold. After realizing they can't transport the Fire, Sorla makes it clear they will protect it, and the Ninja agree that they will help.

When the Ice Fishers and the Ninja head out to prepare, Kai stays behind with Sorla. He explains that he could solve the problem, but without his powers, he can't help. Sorla gives him advice saying Elemental Powers can't be stolen, and it will come back.

The Ice Fishers and the Ninja quickly prepare and by sunrise, they create a fortress and arm the civilians with weapons.

At night, the first barrage of attacks begins when a plethora of arrows come streaking at the Ice Fishers. They dodge it but see Blizzard Samurai at their footsteps. They end up attacking but they shattered into ice when hit. When Lloyd was fighting one of the Blizzard Warriors, he briefly changes faces, but the dark ice corrupting him keeps him evil. During the battle, Kai was attacked by the Blizzard Warrior Grimfax and the latter overpowers him and attempts to destroy him, but Lloyd defends his fellow Ninja before Cole uses his Earth Punch to send him flying. However, the solider doesn't give up and pursues the house with fire and ultimately takes it out. The Blizzard Samurai then retreat after taking out the Fire.

The Ice Fishers sit around the empty Fire, freezing in the winter night. Kai continues to blame himself for not having his Elemental Powers before trying once more. This time, he manages to create the Fire, and the Ice Fishers chant "Fire Maker," due to his success. Kai is excited to have his powers back.

An Unlikely Ally

Kai is approached by some kids, who want him to cook their fish, and he does so while still relishing in having his powers back and is basking at his new title of "Fire Maker." However, his showboating annoys his sister who knocks him off his hammock in annoyance. Later, Cole swings Kai and Jay on the hammock, hilariously ending with Jay flying into a tree, kicking Cole in the progress, and Kai falling off.

When Lloyd talks about him going to the Ice Emperor alone would stand a better chance than bringing the whole group, since by then the Blizzard Samurai would be distracted on the Great Lake; not Lloyd. Kai wishes he could come but reveals that his returning powers are taxing on his body but does give Lloyd food and with the other Ninja wish Lloyd farewell and give him the GPS tracker to the Titan Mech.

The Message

When the children of the village run away from Cole in fear, Kai questioned what he did. He claimed to have told them about how Aspheera banished Zane to the Never-Realm, and Nya asks if that's appropriate for them.

Meanwhile, Uthaug runs up to show the village he found a piece of Lloyd's gi and there were signs of a fight and an avalanche. The Ice Fishers and Ninja are concerned and hoped he is safe.

The Traveler's Tree

In Cole's nightmare, Jay, Kai, and Lloyd were disappointed in Cole after he left the tea behind. They made him go back for it, and the Bounty fell off the cliff.

Jay wakes him up, claiming it was just a nightmare. After he storms off, Kai told Jay he will eventually calm down.

Later, the Kai and Jay asked Nya where Cole was and told her what happened earlier. Boma and Uthaug rush to tell them Cole is also on the mountain, prompting Jay and Nya to go after him while Kai stays behind to protect the village.

My Enemy, My Friend

When Boreal attacks Great Lake, Kai tries to save the villagers but due to his powers being weak, he fails and the Ice Fishers were frozen as a result.

Later, when Cole, Jay, Nya, and Krag saw the village frozen, Kai blames himself for not being able to save them but later comes up with a plan to find the Land Bounty, fix it, and take the fight to the Emperor of Ice. However, when the others agreed with Kai's plan, Kai gets scared by Krag's roar and notices his presence for the first time.

A Fragile Hope

Kai and their friends are searching for Land Bounty when they are chased by wolves. This eventually leads them to the Land Bounty and they used a fire extinguisher to scare the wolves away. Kai is helping Nya and Jay with the fixing the Land Bounty when the wolves return. Krag, Cole, and Jay hold them off and Nya manages to start it up. They use it to outrun the wolves and head for the Ice Emperor's castle.

Once and for All

Kai is with Nya in the drivers' seats, when Nya tells him to tell the others that they are approaching the Ice Emperor's Castle. After everyone buckles up, Nya alerts the team that something big is approaching the Land Bounty and Kai volunteers to take care of it. He leaps up to the cannon above, looking around for the target. When he sees Boreal, he recognizes him and shouts a warning at the others. He takes aim and fires many shots at Boreal, but this appears to not affect him. Boreal eventually seizes the cannon and destroys it. He then reaches for Kai and another part of the Bounty. Kai quickly jumps inside and heads off to join the other Ninja. Nya eventually stuns Boreal for a good amount of time while the Ninja and Krag get their emotions back together.


Kai, destroying Boreal

After managing to incapacitate the beast, they discover it was an elemental creation. Nya tells them that the Ice Emperor could only be Zane, which shocked Kai and the others. He tries to deny this, but he realized she was right due to the corruptive power of the Scroll of Forbidden Spinjitsu that Zane still had. The Ninja decided to warn Lloyd but Boreal regained its strength and attacked, as the Bounty was destroyed in the process.

Kai was left dazed by the attacking Boreal, as he sees his friends panicking. Enraged by the dragon, Kai regained his True Potential and destroyed the dragon, allowing them to progress.

After Zane destroyed his scepter and returned the realm to normal, Kai and the other Ninja soon arrive at the throne and see Zane back to his old self and the latter greets them with a hug.

Sometime later Grimfax took back power and he, along with the Formlings, came to the mutual decision to banish Vex to the outskirts of the Never-Realm for his crimes. Kai returned to the Great Lake with his friends and learn there was no way to return to Ninjago. Upon hearing this, the ninja were distraught, but Cole remembers something and hands Sorla a Traveler's Fruit. In the end, a portal to Ninjago is opened, and the ninja return to Wu's monastery.

Prime Empire Original Shorts


Kai and the rest of the Ninja were chasing The Mechanic after he robbed a warehouse. However, The Mechanic was able to flee quickly. When Nya and Jay join the the Ninja late, Lloyd asked about their previous whereabouts and Jay and Nya lied about what they actually did.

Prime Empire

Would You Like to Enter Prime Empire?

Kai and the rest of the Ninja fight The Mechanic and his crew when they were caught robbing an old electronics warehouse. Kai catches the motherboard when it falls out of The Mechanic's hand, but he is forced to throw it elsewhere when The Mechanic's Henchmen attack him.

Eventually, The Mechanic runs away in his noodle truck, so Kai uses his Katana 4x4 to chase after him. During the chase, he is driven off the road, but Cole manages to chain his vehicle and The Mechanic is arrested shortly after.

The Ninja then explore The Mechanic's Headquarters since he was trying to run away into that building. While Jay is trying to play Prime Empire, the rest of the Ninja continue to explore. At some point, they reach a room containing weird symbols and find a computer asking the Ninja if they found the motherboard. Zane replies with yes and the voice, name Unagami, commands them to play the game which confuses everyone.

The Ninja head back to tell Jay, but he mysteriously disappears.

Dyer Island

The Ninja search around The Mechanic's Headquarters, but cannot find Jay. That's when Nya realizes Jay was able to turn on the arcade cabinet. The Ninja then look on video and discover that the shockwave was from the arcade cabinet as well as Jay being able to enter Prime Empire.

The Ninja interrogate The Mechanic but he refuses to give answers. Meanwhile, the Police Commissioner comes in and reports of all the arcade cabinets turning into Prime Empire. Kai concludes that the shockwave caused all of the games to change.

The next morning, the Ninja would head to Dyer Island in hopes of finding Milton Dyer, the creator of Prime Empire. They encounter many traps such as statues that would fire lasers as well as robot dogs. Fortunately, Bob the Intern turns off the security system and lets the Ninja inside the Dyer Mansion.

The group would ask questions about Milton Dyer and Prime Empire, and after the conversation with Bob, the Ninja believed Milton Dyer was Unagami trying to seek revenge.

Level Thirteen

The Ninja head to Borg Tower to see how Borg's study on the game has been doing. In his office, Borg explains that not only Jay is inside Prime Empire, but over 800 people as well. When they decided teams on who's going into the game while the others find Milton Dyer, they are alerted by the Escaped Prisoners making their way to the office to stop them. Kai then realizes that when Cole began to play the game, he berates him on not even starting and just picking an Avatar. He then attempts to go and fight the Escapees, but Borg tells them that going down there wouldn't be wise, seeing as the security systems will fight anything that is living down there, which includes Kai himself.

Nevertheless, Soto, Ultra Violet, the Mechanic, and a couple of other prisoners make it to the top. Kai and Zane attempt to hit Soto with their powers at the same time, but they collide and create water under Soto's feet. As the Pirate Captain teases them, Kai watches Zane freeze the water beneath him, turning it into ice and causing Soto to slip into the desk. Kai, along with his friends, continue to fight the villains as Cole attempts to reach Level 13. He is busy holding back Soto when Cole manages to do this and goes to follow him into the game. Realizing that Soto and some of the prisoners were trying to chase her brother, Nya lets go of the police tape that she and Lloyd wrapped around Ultra Violet, causing her to fall onto her allies.

Once inside the game with his teammates, minus P.I.X.A.L. and Zane, Kai is amazed to see the Game World around them.

Superstar Rockin' Jay

Kai and his friends continued to look for Jay inside Prime Empire until they are attacked by the Red Visors. He along with the rest of the Ninja attempt to use Spinjitzu and their Elemental Powers, but only end up getting dizzy from spinning with no tornado forming around them and doing Jazz hands. As they duck for cover, Kai reminiscences the time Aspheera stole his powers and berates on how he and his friends always seem to lose their powers. He then witnesses "Jay" fighting a Red Visor and calls to his friends about this, who seem to also see other Jays fighting. Confused on why there was more than one Jay, Cole explains that they are some of the people trapped inside the game and made their avatars look like Jay. When they spot drones coming, the Jays tell them to follow as they double jump to the rooftop. Cole tells them what the double jump was and Kai told him that made no sense, but went with it anyway as the drones followed them.

Being cornered by drones from all sides, the Ninja and Jay Avatars fight the drones. The Jay Avatars being easily able to take them out, while the Ninja struggle with one of their own. Kai jumps on the face of one drone but is blasted off easily by its laser, sending him flying off the building and killing him. Kai then respawns next a grieving Lloyd after seeing his death. Both Kai and Lloyd are confused and Kai is impressed that he just respawned. Following the Jay's advice, they head to an alleyway below after hearing a codename.

The Ninja suddenly spot three Red Visors up ahead. Lloyd, Nya, and Cole hide, but Kai, thinking the game has unlimited lives, stands in the open and taunts the Red Visors. The Red Visors kill him and Kai respawns again after the Ninja defeated the Red Visors. Kai re-spawns and expresses how much he likes the ability of "infinite lives." Cole tries to tell him how lives in a video game work, but Kai ignores him as they move on.

Arriving at the location, which was an empty parking lot, the Ninja are confused by the turn of events; Kai concludes that the Jay avatars are crazy since they love Jay so much when a masked stranger holds them at gunpoint. Nya tells him the code name the Jay Avatars mentioned earlier and the man invites the Ninja inside his hidden garage.

Kai meeting Scott

The man reveals his name to be Scott and what he's been doing in Prime Empire, when Kai foolishly kills himself by touching one of Scott's belongings; because it was an explosive. Upon re-spawning, Kai tells Scott how cool it is to have infinite lives. Scott denies this and shows him his health board, which is down to one. Kai gets mad at his friends for not saying anything and Cole responds by saying when he did try helping him, but he didn't want to hear anything.

I am Okino

Kai and Jay enter Terra Karana arguing about the League of Jays. The Ninja then see a depressed Okino and ask him if he could guide them through Terra Karana.

The Glitch

Kai and the rest of the Ninja head out with Okino into the Forest of Discontent. Their first obstacles are bushes which contain the Thorns of Discontent. Kai decides to take one of lay back and not attack which earns a look from the rest of the Ninja and Okino. Kai then says that he only has one life and cannot take any hits.

Okino and the Ninja eventually reach a point where he thinks the upcoming obstacle could be Strangler Vines. Lloyd finds out it's not, but they are ambushed by the Whack Rats. The Ninja defeat the Whack Rats and Ritchie is tied up. They interrogate him and Ritchie reveals that Unagami ordered them to ambush the Ninja. Lloyd then comments about Unagami preventing the Ninja from winning the game which confuses Okino. The Ninja then explain that Prime Empire is not a real-world and Unagami is the creator of the world. Originally, Okino doesn't believe it causing Jay thinks he is not programmed to understand the truth.

Realizing Unagami is playing dirty, the Ninja are about to leave, but Ritchie urges the Ninja to cut him down because he has an itch. Ritchie then tells the Ninja that there's a glitch in the game that can allow the Ninja to bypass the Forest of Discontent. The Ninja end up letting Ritchie down and he begins scratching his body.

Ritchie guides the Ninja to the glitch and he jumps in. Okino is confused at the sight as the rest of the Ninja enter as well. The Ninja are teleported to a purple cubed room. They walk forward and all of a sudden, the Red Visors appear and begin shooting the Ninja. The Ninja pull out their prime controllers to defend themselves as Ritchie looks on before leaving the room. The Ninja begin to lose lives until Okino enters and fights the Red Visors allowing the Ninja a chance to escape. Everyone but Lloyd manages escape because Lloyd wants Okino to come along. Okino decides to stay with Lloyd as he pushes him through the portal.

The Ninja and Okino land outside the Forest of Discontent. Lloyd thanks Okino, but he is kneeling realizing the world he lives in is not real. Okino thinks he's a pawn, but Lloyd downplays the idea as he tells Okino that he made his own decision, not Unagami. Lloyd then tells Okino to trust in himself and in the Ninja as friends and as an ally to help them get past Terra Karana.

The Cliffs of Hysteria

Kai begins climbing The Cliffs of Hysteria and taunts the Red Visors for not being able to catch up. As they are climbing, Kai does a backflip and lands on one of the drones. He uses the drone to destroy most of the Red Visors before reaching the top with it. He then listens to one of the Red Visors being interrogated by Lloyd before it dies.

The Maze of the Red Dragon

The Ninja and Okino begin dashing through traps and just before Cole asks Okino where to go, Unagami pauses the game to speak with Okino. When the game is unpaused, the Ninja ask again, and Okino once again guides them.

They make it to where the Red Dragon is and the Purple Key-Tana. Jay attempts to steal it when the dragon is sleeping, but the Ninja accidentally awaken it when they save Jay. Nya and the Ninja struggle to attack the Red Dragon until Okino strikes the dragon on its weak spot. The Ninja begin striking that same point until Jay grabs the Key-Tana and takes out the remaining lives.

One Step Forward, Two Steps Back

Kai in his avatar

Jay introduces Terra Technica to the Ninja and they decide to sign up for the Speedway Five-Billion. Unfortunately, they don't have enough credits to enter the race due to Kai spending his credits on a new avatar, and to make matters worse, they are surrounded by Red Visors. Jay fights one of them and is forced to have a weapon upgrade which causes them to need more credits once they are done fighting. They then see an advertisement for a dance competition and decide to enter to obtain more credits.

Jay and Nya begin dancing and rank up points rapidly. This impresses the rest of the Ninja as they didn't realize Jay is an excellent dancer. 

Meanwhile, the Red Visors begin to show up, so the Ninja begin fighting them in the background. Eventually, Jay and Nya manage to win the contest, and fans begin rushing the stage to congratulate them. One Red Visors tries to craw his way towards Jay and Nya, but Kai pokes his back and punches his head.

After winning the competition, Jay and Nya cash out their earnings to enter the race. The Ninja then realize they need cars, but Jay claims he knows someone who can lend them cars, so they head out to Scott. 

Racer Seven

Scott shows the Ninja all of the vehicles he has and commented that he wouldn't race due to having only one life left. Jay replies by saying that some things are worth fighting for, but Scott doesn't want to be a hero. Jay then explains that Scott has been in the game for way too long.

While Lloyd heads out to check out the track, the rest of the Ninja begin making repairs to their vehicles. While Nya is working on her car, she falls and Jay checks to see if she's okay. Nya then gets upset that her vehicle is now destroyed, but Lloyd comes back telling the team that he thinks Racer Seven can drive. However, Scott reveals that Racer Seven is programmed to lose which gets affection from Jay and Nya. Lloyd then goes out to find her.

After a grueling day, the Ninja rebuild four vehicles but still need another one. That's when Racer Seven arrives, so the Ninja and Scott come out to greet her. Lloyd then asks if she will participate or not.

The Speedway Five-Billion

While the Ninja are talking to Racer Seven, the alarm sounds as Red Visors begin shooting the base. Lloyd said he would hold them off, but the Ninja won't let him, so Scott decides to hold off the Red Visors. The Ninja manage to escape, but Jay cries out when Scott is cubed.

The Nina enter the race and the race goes on, more and more racers get eliminated. Jay pulls upfront, he gets side to side with Richie. They both recognize each other and Richie throws a bomb at him. Luckily, Jay ducks down in time for it to go over his jet and hit another competitor, sending it flying back and hitting other race vehicles as well.

Knowing that their friends stand a better chance of winning than them, the Kai and Cole exchange knowing nods. Kai's mech jumps on a Red Visors' car and Cole throws his wrecking ball at two other Red Visors' cars, one being the one he hit with the wrecking ball with and the other he snagged while dragging the other car back. As all the vehicles are about to collide, Kai and Cole wish their friends good luck. A giant explosion occurs and everyone is shocked when two energy cubes fall to the track. Jay and Nya scream for their friends while Lloyd hangs his head down in despair while Unagami's drones pick up the cubes.

Game Over

Kai and the other ninjas are freed from Prime Empire and returned to Ninjago. There, he is reunited with Jay, Wu, Zane, and P.I.X.A.L. Kai wonders if they got the key-tana, to which Jay states that he will fill them up on the events they had missed later. While the ninja are wondering what happened to Unagami, Jay reassures them that, like everyone else trapped in Prime Empire, he's home.

Master of the Mountain


Kai and the rest of the Ninja get excited when they received an invitation to the Kingdom of Shintaro. Later, Kai and the rest of the Ninja head to the Ivory City via the Destiny's Bounty. However, they encounter the Dire Bats. Kai spots a couple trying to tear the sail, so he gets on top of a pole a shoots the beats using fireballs. However, the Bounty still descends after one of the Dire Bats runs into the pole containing the sail. Although all hope seemed loss, the Winged Guards of Shintaro carry the ship while Hailmar greets the Ninja and shows them the Kingdom of Shintaro in the horizon.

Into the Dark

Kai and the Ninja are escorted inside the Throne Room of the Kingdom of Shintaro where they meet King Vangelis and Princess Vania.

During the middle of the night, Kai is alarmed by Cole who describes a purple monster in his room. However, Kai and the Ninja think he's dreaming and tell him to go back to sleep.

The Worst Rescue Ever

Kai and the other Ninja are strolling through the magnificent gardens, and realize that Cole is missing.

Suddenly, Princess Vania appears from out of a tunnel in a frenzy, telling the Ninja that she went into the Dungeons with Cole and found something terrible. There's an underground mine filled with little creatures forced to mine by black skeletons. Cole stayed behind to rescue them, and told her to get help.

The seven of them go to tell King Vengelis, and he is angry at his daughter for disobeying his orders, endangering their guests. He says that he'll send his guards down at once to find Cole, but he will not allow the Ninja to go. The Ninja realize that the creature that Cole saw in his bedroom was real all along.

The Ninja leave the throne room, and make secret plans to enter the dungeons behind the King's orders. Vania agrees to show them the way into the dungeons, and she leads the way back to the garden.

Wu agrees to stay behind with Vania, feeling as though he'll slow the rest of them down. The Ninja enter the cave and find that Vania was telling the truth. Zane detects simple weapons and crude fortifications from the skeletons, and Kai suggests that they bust up the bags of bones, and rescue Cole nice and quickly.

They all agree, and steal the keys to Cole's cage, and free him at last. In order to delay their capture, Zane blocks an entrance off for the skeletons with his shuriken. Cole tells them to keep the volume down, as there's a winged masked man who lives in the temple in the center.

The two tribes of creatures that live in the dungeons, the Geckles and Munce, start to quarrel with each other, causing a ruckus. This alerts the Awakened Warriors, who begin to attack the Ninja. Lloyd orders Jay and Nya to take our the warriors, while the rest of them run away. Kai and the others are in shock, watching the Geckles and Munce call each other "blade stealers." Meanwhile, the Ninja find that the Awakened Warriors go down without much trouble.

While trying to defend themselves, Zane realizes that his Elemental Powers are no use in the dungeons.

All the commotion causes the masked man to exit his temple. The man reveals himself as the Skull Sorcerer, a masked man in a black gown with wings, wielding a glowing green skull. The Skull Sorcerer uses the green skull in his hands to awaken the black skeletons around him, overwhelming the Ninja, leading to their defeat and eventual capture.

The Two Blades

Kai and the other Ninja are put to work by the Awakened Warriors, forced to mine heaping amounts of Vengestone, which explains their inability to use their powers.

After causing a ruckus, they are locked up in a cage with several Geckles. When Gliff picks a fight with Murt, the Ninja begin to wonder where their feud started.

The Geckle explains that long ago, a hero named "Gilly" (who the Munce argues was named "Milly,") entered the mountain with two blades to defend the Geckles and Munce from a terrible dragon known as Grief-Bringer (who the Munce argues was called "Mief-Bringer.") After defeating the dragon, "Gilly" left behind her blades as gifts to the Geckles and Munce— leaving the Ivory Blade of Deliverance to the Geckles, and the Shadow Blade of Deliverance to the Munce.

The two tribe's feud started when the Munce apparently stole their blade, however the Munce argues that the Geckles were the ones that stole the blade. The Ninja come to the conclusion that it was actually the Skull Sorcerer who stole both blades, in order to get control over both tribes. While the tribes fight over themselves, they can't fight the Skull Sorcerer.

Lloyd puts together a plan to get the two tribes to make a truce so they can all break out. Word is passed around through Geckles and Munce about a secret meeting after lunch, and when the time comes, they discuss retrieving both Blades by defeating the Skull Sorcerer.

Later, the Ninja break out of their cages by getting a Minos to eat through their chains. The Ninja split up, while Cole and Lloyd attempt to find the two blades, Zane and the others go about releasing the remaining Geckles and Munce. A few minutes later, chaos ensues, as Cole and Lloyd are chased away by the Skull Sorcerer.

In the commotion, the Ninja are split up so that Jay, Nya, and Lloyd go one path, while Zane and Kai go down another. Kai notices Cole dodging many attacks from the Skull Sorcerer and encourages him to follow him and Zane. Before he could, the Skull Sorcer blocks off the front of their tunnel with an small avalanche, much to Kai's dismay as Cole is further separated from the group as he is chased by the Skull Sorcerer.

Trial By Mino

Kai and Zane in the caverns

Kai and Zane are walking through a cave when they hear Geckles singing while collecting Moss Milk. The two hide, but are caught when Groko falls off his ladder and the Moss Milk lands on Kai. The Geckles think the Ninja work for the Skull Sorcerer and are taken to Gulch.

After tough views from both sides, Gluch decides to place the Ninja in a "Trial by Mino" so they fall into a pit. Suddenly, a Mino comes out and charges at the Ninja. While being chased, Zane recognizes that the Mino has Vengestone armor and is able to remove it. The Mino then calms down and even licks the two Ninja.

The Ninja say they are Elemental Masters, so the Geckles believe they might know "Gilly". Meanwhile, Zane notices Gleck's necklace, and realizes that it is the one Cole claimed to have seen. The two tell them that while they do not know "Gilly", but Zane states that they are looking for their friends. Gulch agrees to help them in light of the dishonor they brought upon themselves by suspecting the Ninja. He then promptly resigns as chancellor and gives the position to Kai, which all the Geckles agree by throwing rocks at him. He accepts the position reluctantly and tells them not to throw things at him anymore, but the Geckles throw more rocks at him in support of his proposal. He then asks for information on the Skull Sorcerer at Zane's suggestion.

Gulch takes them to the story cave and tells them of their people's origin. During their dark ages, a great hero Gilly arrived to save them from Grief-Bringer and gifted them with the Blades of Deliverance, but it was stolen by the Munce. Kai quickly cuts him off, as they already knew that part of the story, and asks about the Skull Sorcerer. Gulch says that three adventurers had ventured deep into the tunnels where all Geckles are forbidden to enter, and awoke an ancient evil - the Skull Sorcerer and the Awakened Warriors. He captured many Geckles and Munce to mine for him, and where they once lived openly, they must hide and pray that the Skull Sorcerer doesn't find them.

Kai decides that to defeat the Skull Sorcerer, he must unite the Geckles and Munce, so he proposes teaming up with the Munce, only for the suggestion to be perceived as a joke. He states that they need a different approach, to which Zane expresses his agreement by throwing a rock at his head.


Kai and Zane discovering Gilly is Lilly

Kai informs the Geckles they'll be attending the truce meeting with the Munce, but the Munce believe it'll be a trap. To decide the matter, Gulch proposes a slug race.

During the race, Gleck pulls Kai and Zane aside and he tells the Ninja that he believes the Munce are not evil and they didn't steal the Blades of Deliverance. Kai recognizes the necklace he's wearing and asks why he went into the palace earlier. After Gleck explained himself, Zane asks for the necklace and discovers the pictures of Cole's parents: Lou and Lilly. Correctly deducing that Lilly is Gilly, in the process. Gleck is exhilarated that the Ninja know Lilly, so he asks Kai and Zane to get her help, but Kai gives Gleck the unfortunate news that Lilly passed away a while ago.

Back at the race, the snail that they want to win isn't winning, so Kai encourages Zane to cheat. Zane questions the move at first, but Kai assures it will be beneficial in the long run. After Zane cheats and allows the snail the Ninja want to win, Kai is excited and they head off to the meeting.

When they arrive, Kai realizes her sister Nya is the leader of the Munce. The siblings hug each other, but tensions between the Geckles and Munce increases. When the Ninja are able to calm everyone down, they hear the sound of Grief-Bringer and they all retreat.

During the retreat, Kai almost lands in the lava as he's crossing the lava field, but Nya is able to save him.

The Darkest Hour

While running away, Kai is informed by Gulch that the Geckle Strong-Cave is the only way to take cover. He's about to shout it out to everyone else, but Gulch thinks he crazy and doesn't want the Munce to hear as well. However, Kai believes they're united.

When Nya and the Munce are trying to close the gate, Kai and the rest of the Ninja head out to buy time for them to close it. The Ninja perform Spinjitzu to defeat most of the Awakened Warriors, but they quickly rebuild themselves. Murtessa is able to break the chains to the gate and the Ninja retreat back in.

Kai thinks they are safe from danger, but Gulch is upset at Kai for allowing the Munces to enter as well. Tensions once rise between the two tribes as they call each other different names.

Even though both sides dislike each other, they both are fearful when Grief-Bringer and the Awakened Warriors attempt to tear down the gate. Nya recognizes a pile of rocks covering something and asks the Geckles and Munce to work together to remove the rocks. Kai marvels at their teamwork, and when they're done, he enters first. However, he discovers there's no other way out.

Murtessa and Gulch apologize to each other and Kai and Nya officially establish peace with the opposing tribes. At the same time, the Skull Sorcerer destroys the gate and is about to fight until the Ninja decide to surrender themselves and allow the Geckles and Munce to be free. The Skull Sorcerer agrees and the Ninja are taken away.

The Upply Strike Back!

Nya and Kai, trapped

Kai and the Ninja are locked up in a cage and overlook the Geckles and Munce working in the mines. He feels remorse for not being able to do anything for the Geckles.

The Skull Sorcerer approaches their cage and informs the Ninja they'll be destroyed by Grief-Bringer. The Skull Sorcerer then reveals himself to be Vangelis and tells the Ninja he disposed Cole and Wu into the heart of the mountain.

During the execution ceremony, Kai and the Ninja watch in fear as Grief-Bringer is about to be released, but he doesn't come out. Cole then shows himself and fights the Skull Sorcerer. The Ninja cheer him on and wish they could join the fight as well. While the Munces and Geckles are also fighting, Plundar and Adam free the Ninja so they could join the fight.

The Son of Lilly

Kai on the Bounty, leaving Shintaro.

Kai continues to fight the Awakened Warriors alongside the Ninja, Upply, Munces, and Geckles. Despite being overwhelmed, they receive aid when Vania and the Winged Guards of Shintaro arrive as well.

After Cole unlocks the Spinjitzu Burst, Kai watches Vangelis being taken away by his former guards.

During the ceremony, Vania is declared queen of Shintaro and she promises peace for everyone. After the ceremony, the Ninja wave good bye as they board the Bounty.
