Jay

Jay Walker is a major protagonist in LEGO Ninjago: Masters of Spinjitzu. He is the Blue Ninja of Lightning, chosen to protect the Green Ninja. He was the first Ninja to master the Spinjitzu technique, and the second Ninja to unlock his True Potential. He was also the second to perform Airjitzu and the third to obtain the Nunchucks of Lightning.

Early life
Jay was born in the Sea of Sand. His parents, inventors Ed and Edna Walker, were the owners of a large junkyard, and Jay inherited his father's knack for inventing and tinkering with gadgets.

At some point, he left his home to test one of his inventions, a set of Mechanical Wings. The wings worked well, but Jay ended up crashing into a billboard. As he picked himself up on the rooftop he fell onto, he met Sensei Wu and learned of his potential to become a Ninja. Interested by the old man's offer, Jay took up residence at the Monastery of Spinjitzu and began his training, meeting Cole and Zane in the process.

Way of the Ninja
Sensei Wu eventually recruited another Ninja, a young blacksmith named Kai whose sister had been abducted by the Skulkin. As Kai neared the end of his training, Jay and the others infultrated the Monastery  and surrounded the blacksmith.

The Golden Weapons
Their fight against Kai eventually took them out into the training yard only for Wu to break up the fight. Like the others, Jay was reluctant when their sensei revealed Kai would be the fourth member of the team, stating that there is only ever teams of three in stories. Wu quickly quieted the matter and provided the Ninja with new gis using Spinjitzu. Jay was given a blue suit, as Wu pronounced him the Ninja of Lightning. Wu proceeded to explain their purpose, to which Kai interjected about when they would save his sister. Jay immediately expressed interest that they were saving a girl, but Wu announced that they would now leave to claim the first Golden Weapon.

As a team building exercise, Wu had the Ninja pull him in the carriage to the Caves of Despair. On the way, the four Ninja told the circumstances of how they met Sensei Wu and agreed that if it hadn't been for their sensei, they would never be seen together.

Upon arriving at the Caves of Despair, Jay asked Cole about the plan to infiltrate the Skulkin camp, but was unable to execute it as Kai ran off on his own. The three other Ninja followed and after stealing the map to Golden Weapons from Samukai, managed to locate the Scythe of Quakes. The Ninja hoped to sneak out while the Skulkin were busy, but Jay unintentionally alerted the skeletons to their presence and thus were waiting when the Ninja emerged from the caves. The Ninja faced their foes and in the process, Jay learned how to unlock Spinjitzu which he quickly passed on to the others. The Skeletons quickly retreated, as the Ninja unfortunately had awoken the Earth Dragon. After Kai attempted to use the Scythe to stave off the beast, Jay used Spinjitzu to escape.

King of Shadows
After getting the Scythe, the Ninja and their master set out to find the next three Golden Weapons. Traveling by boat, Sensei Wu told the four about the Tornado of Creation and its capabilities. When they reached the Ice Temple in the Frozen Wasteland, Zane grabbed the Shurikens of Ice - unfortunately the weapons froze him solid and awakened the Ice Dragon. Jay joined his comrades in lifting the frozen Zane and using him as a sled to retreat to the boat.

Their next stop was the Floating Ruins, where they sought the Nunchucks of Lightning. Jay grabbed the Nunchucks, and the Ninja escaped from the Lightning Dragon with his gliders. They ended up in the Forest of Tranquility, where they made camp for the night. During the night, Kai spotted Nya and followed her to the Fire Temple. Unbeknownst to Kai, this was a trap set by Lord Garmadon, both to claim the Sword of Fire and to leave the others vulnerable to an ambush.

Along with Cole and Zane, Jay was captured when the Skulkin ambushed their camp, taking their Golden Weapons in the process. Jay managed to free himself and his friends after stealing a sword from Nuckal, and the Ninja battled the skeletons as they tried to escape to the Underworld.. After a fierce battle, the Ninja were knocked off of the Skulkin's vehicles as they disappeared into portals, with Jay suffering a blow to the throat that left him unable to speak.

Weapons of Destiny
Jay and his teammates went to the Fire Temple in search of Kai and Sensei Wu, only to see the temple opening up to allow the Fire Dragon an exit. Jay stared in surprise as Kai explained that he had befriended the dragon after revealing that the Ninja were trying to protect the Golden Weapons, but his attention was quickly drawn to Nya as she explained that dragons can cross into the Underworld. He rasped something that Zane translated as a question about Nya's favorite color and briefly celebrated when she revealed it to be blue.

In order to pursue Sensei Wu and the Skulkin, the Ninja recruited the other three elemental dragons, with Jay taking the Lightning Dragon as his steed. After the dragons crossed over to the Underworld, the Ninja tried to sneak into Lord Garmadon's fortress by jumping across the stalactites on the ceiling. As they moved over the fortress, Jay suddenly began panicking, only for the others to brush off his unintelligible babbling. However, the other Ninja soon realized what Jay had already discovered: they were holding onto Spykor legs instead of stalactites.

In their shock, they fell into the courtyard outside the fortress, where they were quickly surrounded by Skulkins and Spykors. In response to Cole's demand for an idea for fighting the horde, Jay attempted to suggest the Tornado of Creation. Although the others repeatedly misinterpreted his rasping, Jay finally got his point across when he recovered from his injury and screamed "Tornado of CREATION!" at the top of his lungs. Despite the risks, the Ninja used their Spinjitzu to perform the Tornado of Creation, defeating their foes in seconds.

With the skeletons defeated, the Ninja proceeded to enter Garmadon's fortress, where they found Sensei Wu battling Samukai for possession of the Golden Weapons. During the fight, Jay enjoyed a cone of cotton candy he had somehow procured, only for Kai to knock it out of his hand as Sensei Wu was defeated. Jay watched Samukai's attempt to betray Lord Garmadon backfire as he was overwhelmed by the combined power of the Golden Weapons, creating a portal that Lord Garmadon quickly escaped through. With their enemies gone for the moment, the Ninja collected the Golden Weapons and returned to the mortal world with their sensei. Back at Four Weapons, they reunited with Nya and renewed their pledge to protect the world if Garmadon - or any other evil - surfaced.

Secrets of The Blacksmith
Jay flew Nya back to Four Weapons with his Lightning Dragon (now named "Wisp"), so she could gather her things and move in with the Ninja. Unbeknownst to him, Nya was attacked by Wyplash and three of his minions within the shop. The sound of a fight caught his attention, prompting him to hurry into the blacksmith, only to find Nya calmly packing the rest of her possessions. He asked her what the sound was, but she replied that it was "just some Samurai helmets and stuff." With that, Jay and Nya climbed aboard the Lightning Dragon and flew back to the Monastery of Spinjitzu.

Flight of the Dragon Ninja
Although Sensei Wu told the Ninja to continue their training, they opted to spend their time racing on their dragons. Jay won the race one day, and began bragging that he was the best Ninja because of it. In response, Cole challenges his friends to another race, with the winner becoming "Dragon Master" for a month.

During the race, Cole and Jay sped through the forest, with Wisp's agility allowing it to dodge around the trees. The group approached the Monastery neck and neck, but Cole arrived first by dangling a chicken in front of his dragon's nose. When Cole proclaimed himself "Dragon Master" for a month, Jay and the others claimed that they never agreed to those terms, challenging the Black Ninja to another race the next day.

The New Masters of Spinjitzu
One night, while the Ninja were sleeping, Kruncha and Nuckal infiltrated the Monastery of Spinjitzu to steal the Golden Weapons. Jay proved to be the most difficult Ninja to separate from his weapon, as he was cradling the Nunchucks of Lightning in his arms, but the skeletons managed to replace the nunchucks with a cotton candy cone before Jay could wake up and notice the switch. Luckily for the Ninja, Kruncha and Nuckal quickly discovered that they could not control the Golden Weapons, causing them to accidentally activate the training course and batter each other with out-of-control Spinjitzu.

Jay was stirred from his slumber when he heard Kai yelling that the training course had turned itself on again. In response to Kai's demand for the glitch to be fixed, Jay grumpily yelled that he would look at it in the morning, apparently unaware that his weapon had been replaced in his arms. He was soon fast asleep once more, preventing him from noticing the Skulkin Generals replacing the Nunchucks of Lightning in his arms before making their exit.

Rise of the Snakes
Sensei Wu implores the Ninja to start training again to prepare for his brother's return to Ninjago, but ever since Lord Garmadon has escaped, they have done nothing but play video games and waste time. Their meeting is interrupted by Nya, bringing word that Garmadon was spotted in Jamanakai Village. The out-of-shape Ninja then travel to Jamanakai village to stop Lord Garmadon, only to find the sighting to be false and the fake Garmadon to be his son who has escaped his boarding school for bad boys "again," Lloyd Garmadon. Lloyd tries to terrorize the village and rob them of their candy, threatening to release the "Serpentine" on the villagers, but is instead run out of town by the Ninja.

In the wake of the incident, Kai discovers he has accidentally taken Sensei's bag in the rush, and finds a scroll that tells of the prophecy of Ninjago; "one Ninja will rise above the others and become the Green Ninja." The Ninja try to hold a tournament to find who is the best of them all, and thus become the Green Ninja. Sensei senses the presence of the Serpentine and quickly alerts the Ninja, who rush to the village and are able to defeat the Hypnobrai. However, Skales hypnotizes Cole before leaving town. After stealing the Snake Staff, Nya uses the anti-venom inside it to cure the villagers, but Cole remains under Skales's influence.

Home
With the threat of Lloyd and the Serpentine looming, Jay and the other Ninja resumed training with gusto. Jay was deflecting arrows with his Nunchucks when Zane suddenly whirled past him, breaking his concentration. After the other two Ninja were similarly interrupted, they questioned Sensei Wu about Zane's oddities, with Jay recalling a time that Zane laughed hysterically at a tragic moment in a movie he was watching with Jay and Nya.

The discussion was interrupted when the Mailman arrived with mail for the Ninja, including a letter from Jay's parents. Noticing that Zane had not received any mail, Jay asked the White Ninja why he never receives any letters from his parents, learning that Zane had been an orphan all his life.

Later that night, Jay joined his friends in laughing at Zane's pink apron before engaging in a food fight in an (unsuccessful) attempt to make his stoic comrade laugh. The next morning, he and the other Ninja were dragged to Wildwood Forest by Zane, who claimed that he had followed a bird to something important. Jay quipped that Zane might have seen a "cuckoo bird", but Zane missed the joke, commenting that cuckoos were non-indigenous to the area.

Nonetheless, the Ninja eventually came upon what Zane had found the night before: a massive arboreal fortress being built by the Hypnobrai for Lloyd. Realizing that Lloyd was trying to get a foothold in Ninjago, the Ninja decided to destroy the fortress, with Kai suggesting that they destroy all three ropes holding up the fort. Jay and Zane ascended the fortress by nimbly jumping up the side of an elevator, and each took position next to one of the ropes supporting the structure.

Once Cole and Kai were in position, Jay used his Spinjitzu to cut his rope, destabilizing the fortress. After Zane cut the second rope, Jay met up with Kai on the roof, planning to jump clear as Cole cut the final rope. Unfortunately, Cole instead opted to leap from his perch and attack his teammates - Zane realized that Cole had been hypnotized by one of the Hypnobrai. With time running out, Jay reluctantly used the Nunchucks of Lightning to electrocute his friend, hoping to literally shock him out of his trance, but the attack failed to break the spell.

Before Cole could bring the fortress down on himself and his team, Sensei Wu and Nya arrived on Flame's back, with the former playing a flute that breaks Cole's spell. Jay accompanied the others in jumping off the roof moments before the entire fortress collapsed, landing on the Fire Dragon's back as it flew to safety. When returning to the Monastery, they find the entire building demolished and burned to a crisp, causing the Ninja to turn on Zane and blame him for destroying their home. When they go to apologize, however, they find Zane leaving on his Dragon, Shard. Later that evening, Zane returns and explains he was following the falcon, which led him to Destiny's Bounty, the Ninja's new home.

Snakebit
Jay's parents, Ed and Edna arrive at the ship to visit, much to Jay's annoyance. After being embarrassed multiple times by his mother, Jay ushers his parents back to their junkyard, where they are assaulted by the Fangpyre and given the venomous snake bite while the others infect vehicles in the yard to their own evil use.

The next day, Jay keeps his promise to his father and visits the junkyard with the other on foot, as the Ninja's Dragons migrated east to begin a transformation in their stage of life. When they arrive, the place is quiet, which worries Jay, since his parents are "never quiet." He finds Ed and Edna captive and beginning their transformation to snakes. While the Fangpyre fight the Ninja, Sensei explains the only way to change Jay's parents back is to get the staff from the anti-venom. After discovering their weapons have the ability to transform to vehicles, Jay uses his Storm Fighter plane to steal the Snake Staff from the Rattlecopter. Nya creates the anti-venom before accidentally loses the staff, and Ed fixes the "defense system" Jay was working on earlier in the episode, allowing them to take flight and escape the Fangpyre.

Never Trust a Snake
Jay joined the other Ninja in asking Zane about what he saw in a dream about the Green Ninja, causin them to slack off on their training. As punishment, Sensei Wu tells the Ninja that they must train constantly until they answer a riddle: "What is the best way to defeat an enemy?" Jay immediately answers, "with your fists," which is incorrect, so the Ninja must train until they figure it out.

The moment Sensei Wu leaves them alone, however, Zane resumes telling everyone about his dream. Jay insists that he must be the Green Ninja because in Zane's dream, the Green Ninja had nunchucks, like Jay. While they're arguing, Sensei asks if they found the answer. Kai answers incorrectly with "train?" so they have to go back to training, but Jay says he can't focus unless he knows who the Green Ninja is.

The next day, the Ninja all agree that the answer to the riddle is "teamwork", only to find that they are incorrect again. When Nya reports that Lloyd and his new Serpentine minion - Pythor P. Chumsworth - are at Darkley's Boarding School for Bad Boys, Jay is reluctant to go, as the school is for the "crooked and misbehaved". After being persuaded by Cole, however, he comes up with a plan to use the anchor of the Destiny's Bounty to surprise the villains. Unfortunately, the impact pushes the Ninja to the bottom floor, forcing them to make their way up to the roof while avoiding Lloyd's booby traps.

Jay takes the elevator and nearly falls asleep due to the music. When he arrives at the top floor, Cole (still recovering from one of the traps) points him in the direction of Pythor. making Jay the only Ninja to reach the villains. Before he could engage Pythor and Lloyd, the scheming Anacondrai betrays the boy, taking his map and leaving him all alone with Jay. The Blue Ninja apprehends the would-be evil overlord as Sensei and Nya arrive on Destiny's Bounty along with the other Ninja. The Ninja try to think up a suitable punishment, but Sensei knows what to do.

Later that night, Jay along with the other Ninja are furious that Lloyd was read a bedtime story and not being punished and they had to spend all day training. Sensei reveals the answer to the riddle: To make the enemy your friend. This changes Jay's mind about Lloyd.

The Snake King
Jay ate with his fellow Ninja in the wake of their failure to stop Pythor from unleashing all of the Serpentine tribes, discussing the loss of the Sacred Flute and the mysterious Samurai X. He was particularly enraged when the mysterious samurai repeatedly beat the Ninja to every crisis, and agreed to the bet that whoever caught the samurai would be worthy of being the Green Ninja.

Jay attempted to trick the samurai by disguising himself as a woman and tying himself to railroad tracks in the path of an oncoming train, only for Samurai X to redirect the train instead of grabbing him. Later, Jay accompanied his fellow Ninja in searching for Lloyd, who had gone missing. Their search led them to The Lost City of Ouroboros, where they discovered that Pythor had successfully united the Serpentine under his own leadership and captured Lloyd. Their rescue attempt was thwarted by a trap in the arena, and Jay found himself and his allies deprived of their Golden Weapons and forced to fight Samurai X in the Slither Pit. The enigmatic samurai managed to help the Ninja escape and retrieved the Golden Weapons, but his Samurai Mech crashed in the desert and separated Kai from the others. When Kai returned with the Golden Weapons, Jay asked about the samurai, but the Red Ninja claimed that Samurai X had simply given back the weapons and left without a word.

Tick Tock
With the Serpentine's threat growing greater by the day, the Ninja continued to push themselves further in their training. Jay once climbed atop a massive skyscraper in the middle of a raging thunderstorm, balancing himself atop a lightning rod with one hand and performing various acrobatics. He later bore witness to Zane breaking his old breath-holding record, sharing his teammates' shock when the White Ninja remained underwater for over ten minutes.

Once Bitten, Twice Shy
After listening to Nya's theories on how an increase in heart rate might be able to counter the bite of a Fangpyre, Jay asked her out on a date, to which she agreed. In his joy, Jay accidentally pricked himself on the fang of a Fangpyre skeleton, causing him to slowly transform into a snake. Nonetheless, he took Nya on a date, which ended up being at the Mega Monster Amusement Park when the Ninja discovered Pythor and the other Serpentine searching for the first Fangblade.

In the process, Jay learned that Nya was Samurai X and ended up trapped on a roller coaster ride meant to destroy him and his girlfriend. However, Nya was able to cure his Fangpyre infection with a kiss, and Jay unlocked his True Potential to save Nya and himself from the trap, although Pythor still escaped with the Fangblade.

The Rise of The Great Devourer
As the Destiny's Bounty flew towards Torchfire Mountain, Jay ate a sandwich in the dining room and conversed with Kai and Nya about the Fangblades and Lloyd's destiny as the Green Ninja. Cole burst in during the conversation, rather ill from the turbulence of the ship, and Jay only provoked his nausea by offering him a bite of his sandwich.

The next morning, the Ninja were preparing to throw the Fangblades into Torchfire Mountain when Sensei Wu began speaking oddly, having foreseen his own death in the near future. Jay did not understand his mentor's words, but further discussion was halted when the ship suddenly jerked to one side. Jay joined his peers in forming a human chain to catch Sensei Wu before he fell into the volcano, but this allowed Pythor (who had snuck aboard the ship and sabotaged the engines) to retrieve the Fangblades and make his escape on a Rattlecopter.

After Nya saved the Ninja and Sensei Wu with her mech, Jay joined his comrades in pursuing the fleeing Serpentine. When the snakes transformed their getaway vehicle - a Tour Ninjago" bus - into a mobile fortress, Jay helped Nya draw its fire so Zane could disable the heavily-armed rear section. With the train's main weapons removed, Jay joined the others atop the next car, where they agreed to race each other to the front. In the resulting race, Jay opted to swing through a window and perform Spinjitzu immediately upon landing, allowing him to knock the Serpentine occupants out of the car before he could even register the effect of his attack.

Eventually, Jay reunited with his team at the front of the penultimate car, with only Pythor and the Fangblades ahead. Before anyone could move in, Sensei Wu dashed to the other side of the connector and disconnected the front car from the train, leaving his pupils stranded in the desert while he confronted Pythor himself. Jay waited on the remains of the train until Lloyd came by with the Destiny's Bounty and airlifted the vehicle to Ouroboros. Unfortunately, the Ninja arrived too late - Pythor had already revived the Great Devourer.

Child's Play
Jay, along with the other Ninja are turned into kids by Lord Garmadon and are chased by the Grundal. He and his friends try to defeat the Grundle, but the beast is only defeated when Lloyd uses Tomorrow's Tea to undo the effects of the Mega Weapon, reducing the Grundle to a skeleton and aging the Ninja (including Lloyd) back to teenagers once again.

Wrong Place, Wrong Time
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 find out about his plan and jump into the portal Garmadon created with his Mega Weapon to stop him. The Ninja get back in time and fall through a portal. 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 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. Jay, Zane and Cole  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. Jay, Cole and Zane took the past golden weapons to destroy the Mega Weapon and Jay, along with other Ninjas comes back safely.

The Stone Army
Starts when the Ninja are awoken by their alarm clock. Later, Jay helps to fight the Stone Warriors. One stone warrior keeps the Ninja running away. They stop inside a large room and close the doors, and as the Stone Warrior begins to break it down Lloyd suddenly comes up with a plan and tells the Ninja to distract it.

The Day Ninjago Stood Still
Jay 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 Sensei 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. Jay continues to help hold off the Stone Army.

The Last Voyage
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 and has a hole in the side, the ship runs ashore on an island with a prison tower. When the Ninja get to the top, Dr. Julien greets them and takes them in. Later, the Ninja sail further to the island of Darkness.

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. Lather 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.

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, Jay's armor transforms, and an Elemental Blade with the power of Lightning appears in his hand as well as the other Ninjas. 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. Jay electrocutes a whole line of enemies with a single touch, Lloyd summons the power of the Golden Dragon, creating a brilliant light that frightens the remaining stone soldiers into retreat

The Last Hope
At the beach, Dr. Julien repairs the Falcon, while the Ninja celebrate their restored powers by shooting down coconuts. The party is interrupted by Sensei 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 superweapon. 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 Sensei 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. Surviving the fall, the Ninja head off to prepare for the final battle, with Jay angered at Nya's capture.

Return of the Overlord
Jay and the others intend to start the final battle and attack the Stone Army base, only to find it empty. They see the Garmatron's tracks and follow them. As they run, the Ninja reflect on all of their adventures, but the jovial mood is broken when they sense an evil presence nearby. Suddenly, a crimson Spinjitzu tornado hits Cole and Lloyd, and stops in front of the group to reveal Nya who has been turned evil by Lord Garmadon, and the Ninja buy time for Lloyd, Sensei Wu, and Misako to stop The Overlord and Garmadon. Later the Ninja have a rough time against Nya, until Zane realizes that they can use their elemental powers on the environment instead of their opponent. He uses his Elemental Blade to break the chain of Nya's weapon; Jay creates an electric barrier to deflect thrown needles; Cole blinds Nya with a cloud of dust; Kai cuts down a nearby tree so its leaves surround his corrupted sister. Finally, Zane freezes the tree, leaving Nya trapped within a dome of ice - wryly commenting that "this club just became boys only," Kai leads the others down the Garmatron's trail.

Ninja rush up to their allies and start to fight the stone army. Meanwhile the battle continues on the beach and Lloyd is defeated. Fed up with the interference, the Overlord creates a portal for his army, declaring that they will go to Ninjago City personally to finish the job leaving the heroes trapped on the Island of Darkness.

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. Jay and the other Ninjas proceeded to ascend the tower but only to be victim of the Overlord's corruption. 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. Jay reunited with his allies in the crater left by the Garmatron's disappearance.

The Surge
Following the battle with the Overlord, the Ninja now teach at Sensei Wu's Academy - which has replaced Darkley's School for Bad Boys - training a new generation of Ninja. Later they are invited by Cyrus Borg for a field trip to Borg Industries' Borg Tower.

As the Ninja arrive in the office of Cyrus Borg, the Ninja were all very happy to meet him. Cyrus shows them to a gift he wanted to give them: an automated statue of himself. It looked like a regular statue, but Cyrus tells Kai that he should protect "them" with his life and to not let anyone know he had them. Walking into the elevator with their gift, they accidentally drop the statue, yet they discover it is hollow and is filled with new suits as well as the Techno Blades. Suddenly a robotic security voice in the elevator says that they should drop the blades. The Ninja refuse, 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, Sensei Wu takes the Techno Blades and says that he wants Jay and Cole on the ground. Then Jay manages to hack a Security Tank with his Techno Blade, making it the Thunder Raider. In the moment they almost get destructed, Lloyd comes on the Golden Dragon, defeating the robots. As the Ninjas 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 which 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
After escaping from New Ninjago City, the Ninjas are hides their vehicles. Misako then greets them and shows them to the Monastery, but Zane offers stay behind with the Techno Blades, as Garmadon (whom is now "Sensei 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 tie 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 Sensei Wu. Suddenly, P.I.X.A.L. realizes she did not come alone and Nindroids surround the place. Ninjas successfully defeat the Nindroids by trapping them into mill wheel which then roll out. However, General Cryptor destroys Ninja's vehicles. After that, the Ninjas 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 to the station, but with high guard of Nindroids. They manage to get inside but can't find the 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.

Blackout
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. The operation is a success and the android is re-activated. However the moment quickly goes sour when P.I.X.A.L claims that Nya and Cole are a better couple then Nya and Jay. Jay overhears this as he comes in and he attacks Cole.

Unbeknownst to the Ninja, Techno Wu arrives via hover-copter and powers General 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 Ninja are still trying to break the battle against the two Ninja, but are failing. The tiny droid uses the crane and launches the truck at a garbage pile. 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. Then, Cryptor attacks him and P.I.X.A.L, but Zane uses his Techno Blade as a shield. Jay and Cole sees that their friend is in a difficult problem, and decide to help. Just as they run to Zane, their former sensei, Wu, traps the two in a pit. Nya managed to get by the controls of the pit, but she has a new problem to face: there are two wires, colored black and blue, and Nya has to cut one. If she destroys the wrong one, Jay and Cole will be crushed. Nya frees Jay and Cole and they assists 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
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 Tomb, 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 findns 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.

Enter the Digiverse
In the top of the Borg Tower, Borg prepares the device that will lead the Ninjas to the Digiverse, 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 Ninjas are "downloaded" successfully, and they wake up in the Digiverse. In no time, they begin mastering the advantages of the digital world. 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. 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, Sensei Wu spots General Cryptor aboard a train heading for Ouroborus. He tries to send Jay and Cole to investigate, but they are fighting over Nya once more at the movie theater. As night falls, Nya, Jay and Cole get out of the cinema and then Jay and Cole ask her did she decide which of them she will pick. She said that she will pick Jole, a robot created by her that is mixture of Jay and Cole--a decision that is rendered moot when it freaks out and runs away. When they see light coming from Borg Tower, they get up to Borg's office where they find Garmadon, Wu, Lloyd, and Zane who tell them that the Overlord is alive and is holding Kai hostage. They realize how the name Arcturus is actually a clue about the Overlord's new plan, although P.I.X.A.L is unable to find anything related, since she has every point in time of Ninjago's history in her database. Zane and Garmadon remember how they and the others went back in time and destroyed Garmadon's Mega Weapon--an event that P.I.X.A.L, Lloyd, and everyone else never knew about because the past and present had been altered.

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
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 Sensei Wu, Garmadon, Nya, and P.I.X.A.L..

The Ninjas put the space suits just as the rocket disengages its un-needed 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 in their own while using the pursuing bugs against their robotic adversaries. The Ninjas 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
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. Reheartened 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 Ninjas 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 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 begin travelling 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, Wu, and Garmadon. There Cyrus gives them the ultimate weapon—a pill. Borg then explains that it was no ordinary pill, it could make anyone shrink. Garmadon and Wu decides 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 try 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. He later passed 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. When he finished the speech, snow began to appear.

The Invitation
After Zane's sacrifice, the team broke up. Jay now hosts his own T.V. show to find a new hero for Ninjago. He introduces the player as Cathy, a returning contestant and asks why she came back after losing last time she competes. She states that a Ninja never quit and starts jumping through obstacles. However, she fails but is proud to have gotten farther than the previous time. After the game is over, Jay goes to his dressing room, where Lloyd surprises him and tells him to rejoin the team Jay declines, due to his hatred against Cole for Nya's feelings towards him and Lloyd disappears, while telling him to visit him if he changes his mind. He later reunites with Kai, Cole, and Lloyd. Lloyd informs the Ninja his new plan: hiring a new Ninja. The others completely dislike the idea, saying Zane is not replaceable. They quickly get interrupted by Eyezor and his gang.

The Ninja go to the back of the shop after they've stopped Eyezor's gang and see a drawn picture of Zane attached to a shrine with an invitation to a 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 judgement of Clouse, Chen's ex-second-in-command, Garmadon accompanies the Ninja on board, where they meet the other Elemental Masters.

Versus
Despite seeing the truth of the tournament, he decided to take the next day off, which disgusted Cole and getting them into another argument. Although he states none of the ninja are competing for the day, Chen immediately announces Kai as one of the competing masters. After the ninja of Fire defeats Ash, the ninja and Garmadon cheer for him. Later, Clouse arranges for Jay and Cole to fight each other later that evening to which Kai suggests enlisting Neuro to stop the fight. After this fails, the fight begins where neither one holds back until Cole states he doesn't want Jay eliminated and that Chen is their enemy. Upon hearing this, the blue ninja admits what happened between him and Nya was his fault and agrees to fight without using their powers. To this end, Chen decides for the both of them to be knocked out. Jay tells Cole to take the jadeblade as he considers himself lucky to still be in the tournament, but Cole throws it to Jay, telling him to win for him, that he should have let him have Nya and that he should have backed out before being eliminated, renewing their friendship and ending their rivalry.

Shadow of Ronin
After relocating to Spinjago, Jay listened to Kai retell the events on Chen's Island to the other Ninja, though protested when the Ninja of Fire claimed that Clouse's serpent ate Jay's entire pants, not just a hole. Following the story, the Ninja began to train but that was interrupted by the arrival of Ronin who stole the Ninja's 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. Needing Nya's grappling hook to traverse it, they went to pick her up from Ed & Edna's Scrap N' Junk, though Jay regretted not bringing his dirty laundry.



Once arriving in the Toxic Bogs, Jay expressed concern that they should instead try a less hazardous Toxic Bogs, and grew annoyed when Wu claimed that they had been in much more dangerous places, of which Jay currently had no memory. Despite it tasting gross, Jay drank the Tea of Insight and learned that the Obsidian Nunchucks was hidden in the Floating Ruins. Though he pleaded for them to find the Nunchucks first, the team decided to go to the Caves of Despair to find the Obsidian Scythe was hidden.

At the Caves of Despair, Jay and Zane lagged behind Cole and Kai, so when an earthquake happened, the Blue and White Ninja became trapped between two boulders. With a limited oxygen supply the two waited anxiously for Cole to return with his elemental abilities. The Master of Earth eventually did, and they continued on to the Fire Temple to retrieve the Obsidian Sword, much to Jay's dismay.

Jay accompanied the other Ninja to the Frozen Wasteland where Zane acquired his Obsidian Sais. There, Zane remembered that Ronin was who took them to Chen's Island, though with no memory of Chen, he listened as Kai and Cole recapped Zane's death for him. 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.

Jay 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.

Upon arrival at the Lightning Temple, Jay was outraged to learn that Cole had once dated Nya. However, he was quickly interrupted by visions from his past, and soon found the Obsidian Nunchucks. As his memories came back to him, he went back in forth between liking and hating Cole, but the most prominent thing he remembered was his overdue library books. 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. With his Lightning powers, Jay was able to hold off Ronin for a short while, but they were eventually forced to retreat.

Later Sensei 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 release the ninjas. Back in Spinjago, Sensei Wu realizes that Ronin needs the Primal Fulcrum. They travel to the Fangpyre Cemetery to find Lloyd and Misako to help them. Unbeknownst to the Ninja, Ronin 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 ninjas into activating a fail-safe. After destroying the Obsidian Glaive, Ronin and his goons escapes destroy the entrance to the room to avoid being followed. Later the ninjas follows Ronin to Chen's Island to avoid him to open the portal to the Cursed Realm. But the Ninja did not stop and instead entered the now giant sized portal on their elemental dragons and the ultra dragon to stop him once and for all. After they had searched different portals to find him and manage to build an entrance to the portal he was hiding in, they where finely 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 ninjas. But as the battle continued, the ninjas manage to destroy each of the Forges that powered his elemental form, until they where 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 too. Then Kai points that Jay lost his pants again. It turns out Kai is retelling the events again and Jay complains about it, but everyone laughs nonetheless.

Winds of Change
Jay and the Ninja used their Elemental Dragons to capture a Fangfish that had been terrorizing a local village. Upon returning successful to Wu's new tea shop Steep Wisdom, Jay and the others were sent by their Sensei into Ninjago City to advertise the new store, yet without using their powers. While they obeyed their sensei at first, after failing to attract anyone Jay decided to use his elemental powers to project giant teapots on all the nearby electric billboards.

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. Jay attempted to use Spinjitzu to fend him off, but in the end the Ninja were forced to retreat with Wu and Nya in the Destiny's Bounty.

Ghost Story
Morro soon caught up to them using his Elemental Dragon and Jay mounted one of the cannons in an attempt to fend him off. The ghost boarded the ship however and while Wu made an imprint of the staff's secret message, the masters of earth and lightning tried to fend him off. They were defeated with ease however, and turned their attention to helping Nya stabilize the ship as it crashed in the Forest of Tranquility.

The Ninja made camp and Wu told them of his past with Morro. The next morning Misako arrived and discovered that the first symbol means Airjitzu, a martial art created by Sensei Yang. The Ninja mount wallipers and the Blue Ninja followed Kai 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 Sttix, 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 Jay helped lay down the planks. 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.

Through his leadership, the Ninja successfully entered Ronin's shop (though broke a skylight in the process), but were unable to find the scroll before Morro and the Soul Archer secretly arrived (keeping Ronin hostage). The Soul Archer possessed an organ, grabbing hold of Jay with it, but after a bit of chaos the other ninja managed to find a jug of water to release him. The shop was immediately flooded with ghost warriors, leaving the ninja unable to defend themselves, up until Ronin showed them the Aeroblades. When Jay received his, it glowed yellow.

After fending off all of the ghosts but Morro, Ronin confronted him, but in the struggle, the hidden scroll was revealed. Ronin quickly grabbed it and flew off in R.E.X., but Morro knocked him down, and he was forced to flee from Morro and the Ninja on foot. After Morro caught up and snatched the scroll, the Ninja gave chase to him, but were slowly picked off one by one (Jay first, by falling through a roof). After they met up later, after the chase had ended, Jay admitted that he didn't want to be leader any more.

The Temple on Haunted Hill
Jay went with the other ninja to Yang's haunted temple to get the scroll of Airjitzu, they were put in a test to face their fear,when they did it, it was almost sunrise, they ran, Kai, Jay and Zane were saved, but Cole was turned into a ghost.

Peak-a-Boo
Jay was practicing alongside Kai and Zane Airjitzu, later when Misako deciphered the next clue to the Tomb of the First Spinjitzu Master. He used his mech to get to the Wailing Alps, but it was eventually destroyed by an avalanche, they managed to get to the Hanging Temple, there they fought the Ghost Warriors, when they escaped, they climbed the mountain. When they thought that they will lost the Blind Man's Eye, they used Airjitzu to get to the top and get to the eye of the storm to find the Sword of Sanctuary.

Appearance
Having short, orange-brown hair, Jay generally wears blue clothing to represent his elemental color. On his unique-looking frowning expression, he has a notch in his right eyebrow.

Personality
Jay is the most light-hearted of all the Ninja. He is always telling jokes, most of which are only funny to himself. He enjoys boasting about his abilities, much to the annoyance of the others, but he proves to be a good friend and a skilled fighter. He is also somewhat high-strung, typically being the first to panic in stressful situations.

Jay is fond of inventing and the color blue. He has a crush on Nya, and often stumbles on his words around her, although they both eventually reveal their feelings for each other.

Weapons and Abilities
Lightning Abilities= Jay can harness the power of Lightning to create a Spinjitzu tornado of pure electricity. His lightning powers were enhanced further by the Nunchucks of Lightning, and later by his Elemental Blade. In close-range combat, he favors nunchucks, but has used katanas and various improvised weapons on occasion.


 * -|General Abilities=Jay has an eye for machines and gadgets, being in charge of repairing and maintaining the various technology at the Ninja's disposal. He was responsible for restoring the Destiny's Bounty to a functional state and equipping it with the modifications needed to make it fly. Over time, his inventing side was less emphasized, due to Nya and Dr. Julien taking up the role of gadgeteer, but Jay's skill with technology should not be underestimated.
