Wu

Master Wu is a wise old man and the mentor and master to the six Ninja (Lloyd, Kai, Jay, Cole, Zane, and Nya). He is the First Spinjitzu Master's second born and remaining son, Misako's brother-in-law, Garmadon's younger brother, and Lloyd's paternal uncle. Wu endured a traumatic childhood as his big brother Garmadon was bitten by The Great Devourer and infected with evil. After a battle between brothers broke out, Wu cast him into the Underworld.

Not long after, Wu began to train four teenagers - Cole, Jay, Kai, and Zane - in the ways of Spinjitzu before sending them out to find the Golden Weapons. After Lloyd released the Serpentine, Wu discovered his nephew's destiny was to become the Green Ninja, and immediately oversaw the four Ninja as they trained Lloyd. Wu was was later reunited with Garmadon's wife, Misako, who joined Wu and the Ninja in their battle against The Overlord and the Stone Army. When Lloyd defeated the Overlord, Garmadon was purified of evil, much fo Wu's relief. When the Nindroid conflict began, Wu was captured by the Digital Overlord and corrupted into a spiteful cyborg. After the Digital Overlord was vanquished, Wu was purified and aided the Ninja as they fought the Overlord and his army. The battle ended when Zane sacrificed himself to defeat the Golden Master.

The loss of Zane disbanded the Ninja team until they reunited to find him on a mysterious island. Upon discovering their whereabouts, Wu sent out Nya before uniting with the Elemental Masters. At the Corridor of Elders, Wu helped fight an old enemy and his army until his brother was banished to the Cursed Realm in an effort to end the war. Following the loss, Wu retired and opened a tea shop. When his first pupil, Morro, possessed Lloyd and embarked on a quest to find his father's tomb, Wu trained Nya to harness her element and fight the ghosts. After Morro claimed the Realm Crystal and freed his master into Stiix, Wu helped evacuate the city as Nya destroyed the Cursed Realm, along with Morro, who accepted his fate. Shortly after, a vengeful djinn sought vengeance for the destruction of his home realm, and he trapped Wu in the Sword of Souls. After Jay made his final wish, recent events were reversed and Ninjago was left safe.

On the Day of the Departed, Wu led the Ninja during their day of remembrance, as he commemorated his father at the old monastery. However, Cole accidentally revived the Ninjas' old enemies, including Morro, who confronted Wu at the monastery and told him of Yang's plans to isolate Cole and defeat the Ninja. With Morro's help, Wu reunited the team before setting off to Yang's Temple, where he witnessed Cole become a human once more.

Early Life
In Wu's childhood, he and Garmadon were the best of friends. One day in his youth, Wu lost his father's katana during a spar, and Garmadon climbed over the wall to retrieve it. While outside, The Great Devourer bit Garmadon's hand, corrupting him with its venom. As a result of the growing evil within him, Garmadon became increasingly distant from his family, but he and Wu would remain civil with each other for some time. After their father died, Garmadon and Wu vowed to protect the Golden Weapons.

Centuries later, his brother left to train under Master Chen, Wu found a young boy, Morro, rummaging through the monastery's trash cans in search of food. Wu took pity on him and trained him in the ways of the Ninja. He soon discovered that Morro was a descendant of the Elemental Master of Wind and believed him to be the Green Ninja. This ended up being his greatest regret as the thought of the power that came with the title made Morro incredible arrogant and he flew into a fit of rage when the Golden Weapons did not react as they would when in the presence of the chosen one. Wu was disappointed, but still would not give him the Green Gi, as it was not his destiny. Morro left vowing to find the tomb of the First Spinjitzu Master.

Garmadon eventually returned to fight alongside his brother and the Elemental Masters in the Serpentine War, where they imprisoned the Serpentine, exiled Chen and Clouse, and banished Arcturus to the Cursed Realm.

Decades later, Garmadon married Misako and fathered Lloyd, Wu was happy for his brother, but also somewhat melancholy, as he personally harbored some affection for Misako. During the war he had written her a heartfelt letter confessing his feelings, but it was intercepted by Chen, who convinced Garmadon to sign his own name to it in place of Wu's in order to win Misako's affections; Wu did not learn this until years later.

Garmadon eventually succumbed to the darkness from the Devourer, and planned to steal the Weapons. But when he tried, Wu confronted him and they fought. Wu won the battle, but at a cost. The kimono he was wearing had a protection spell to keep him safe from evil. This in turn worked on Garmadon, and cast Garmadon into the Underworld, banishing him for what could have been eternity.

Peace returned to Ninjago, but knowing his brother's ambition to get all Four Weapons, he sealed each one away and placed a guardian to protect each individual one. Fearing his own demise one day, Wu created a map of the weapon's location and entrusted it with an honest blacksmith.

Years later, Wu began searching for the descendants of some of the Elemental Masters to train them in the way of the Ninja. He found Cole climbing a tall mountain, Jay on a city rooftop after his glider failed, and Zane at the bottom of a frozen pond testing himself. He brought each one back to the monastery to train them together.

Way of the Ninja
Wu eventually returned to Ignacia in the hopes of convincing the blacksmith's son Kai to become the Master of Fire, and thus eventually the caretaker of the Sword of Fire. Upon arriving however, he was disappointed that Four Weapons sold only tools for a samurai and voiced his complaints. In response, Wu was promptly ordered to leave by Kai.

Yet Wu didn't get far as the Skulkin Army soon attacked the blacksmith shop. Kai was quickly defeated by Samukai and Wu rushed in to save him, using Spinjitzu. The Skulkin General used his daggers to topple the nearby water tower as a distraction, and Wu hurried to save Kai from being crushed by it. Wu was alarmed to hear Samukai mention Garmadon as the Skulkin captured Nya, yet didn't have time to contemplate the matter as Kai attempted to go after them. Wu told Kai of the Golden Weapons and advised him to become a Ninja in order to save his sister.

Master Wu took Kai to the Monastery of Spinjitzu atop the Mountain of a Million Steps where he gave the blacksmith one simple instruction; finish the training course before he finished his tea. However, Wu finished his drink even before the young blacksmith had a chance to start and told him to try again the next day, hoping to teach him patience. Kai eventually succeeded and Wu told him that a final test would come the next day.

The Golden Weapon
That night Jay, Cole, and Zane arrived at the monastery and attacked Kai. Wu eventually awoke and rushed out to the training yard to stop the fight. There he used Spinjitzu to give them their appropriate gis and announce their name and element. He then explained their mission before deciding that it was time to retrieve the first Golden Weapon.

To get there, Wu had the Ninja pull him in a carriage as a team building exercise. Upon arriving, Wu warned them not to use the scythe once they found it, and remained behind while the Ninja infiltrated the skeleton's mines.

Yet Kai ignored Wu's warning and used the weapon in defense against the Earth Dragon, thus creating a large opening in the ground which the Ninja used to escape. Wu chastised Kai for his actions and walked back to the carriage to go the next weapon.

King of Shadows
As the Ninja sailed through the Frozen Wasteland, "drifting aimlessly for miles," Wu took a perch on the dragon sculpture at the front of the ship they were using. Wu unexpectedly turned around and informed the Ninja about the Tornado of Creation, before the ship crashed into the Ice Fortress. After they claimed the Shurikens of Ice, Wu sent the Ninja alone to retrieve the Nunchucks of Lightning from the Floating Ruins while he prepared a camp in the Forest of Tranquility.

That night the Ninja celebrated their success thus far, though Wu was hesitant as they had yet to claim the Sword of Fire. Nevertheless Kai manage to convince him to show them some dance moves before they all fell asleep.

Later that night, Kai was lured to the Fire Temple by Garmadon and Wu followed, arriving as his brother was using his shadow to defeat Kai. Wu used his own shadow to stop Garmadon and recovered the Sword of Fire, only to learn that the Skulkin had stolen the other three weapons. Kai, Wu, and Nya attempted to escape from the Temple to help the other Ninja, but Garmadon awoke the Fire Dragon who quickly blocked their way out. Realizing the Skulkin were on their way to unite the weapons, Wu used the Sword of Fire to cut a rock free from the pool of lava, thereby sending himself into the Underworld with the Fire Sword to keep the weapons apart.

Weapons of Destiny
Upon arrival in the Underworld, Master Wu headed straight for Lord Garmadon's Dark Fortress, where he confronted his brother in the throne room. He easily defeated the Skulkin soldiers sent after him, but soon faced a far greater challenge: Samukai, wielding the other three Golden Weapons. Master Wu fought hard, using the Sword of Fire to great effect, but Samukai's use of the other Golden Weapons overwhelmed him, leading to his defeat moments after the Ninja broke into the fortress themselves.

As Master Wu recovered his wits, Samukai took the Sword of Fire and challenged Lord Garmadon for the throne of the Underworld. However, Garmadon simply laughed, revealing that the power of all four Golden Weapons was too much for anyone - even himself - to control, and Samukai was disintegrated as the weapons formed a portal. As Garmadon prepared to enter the portal, Master Wu tried to reach out to his brother, claiming that their father would not have wanted any of this to happen. His pleas were rebuffed by Garmadon, who revealed that his real plan was to trick Samukai into using all four Golden Weapons at once, thereby creating a portal to a realm where he could find the power to safely wield the powerful weapons himself. With that, Garmadon fled through the portal, leaving Master Wu and his pupils to gather the Golden Weapons and return to the mortal realm.

Return of the Serpentine
Main article: History of Wu (Rise of the Serpentine)

Darkness Shall Rise
Master Wu and Nya leave on a one day road trip to get medicine for the Ultra Dragon and some other things, and returns just in time to save Lloyd from Skales who was plotting to kidnap him and convince Garmadon that he (Skales) should be in charge.

Pirates Vs. Ninja
Wu observed Kai train Lloyd in their apartment, though when the Ninja agreed that their conditions weren't suitable to properly train him, Wu sent them out into the city to find a better place.

Child's Play
Master Wu saw the Ninja off on their mission to the Ninjago Museum of History, where Lord Garmadon was attempting to revive a Grundle. When the Ninja did not return from their mission (due to being de-aged into children as a side-effect of Garmadon's spell), Master Wu joined Nya in searching for them. Their efforts proving fruitless, the duo returned to the Bounty, only to find a message from Lloyd, asking them to meet him and the Ninja at the Ninjago Doomsday Comix Book store.

Putting some of the pieces together, Master Wu has Nya accompany him to Mystake's tea shop, where they request some Tomorrow's Tea. Due to Mystake having trouble finding the tea, Master Wu and Nya did not reach the comic book store until nightfall, finding the Ninja at the mercy of the revived Grundle. After Lloyd uses the Tomorrow's Tea to restore the Ninja and defeat the Grundle, Master Wu witnessed the Green Ninja aging into a young man along with his friends.

The Stone Army
Wu and the Ninja travel to the Museum after the Devourer's venom has made the Museum's gift shop bobbleheads come to life. One escapes, and Wu races after it, crushing it with his foot, only to turn around to find Misako, Lloyd's mother, greet him. When the giant Stone Warrior is unveiled, the Devourer's venom drips on it, bringing it to life. Wu and the other escape it for a short period while Lloyd works on a trap. Misako finds Lloyd, and Lloyd tricks the warrior into standing on top of paper covering up the bottomless pit it was found in. Wu invites Misako to join the Ninja, and she says only if her son allows it. Lloyd allows her to, and she lives with the Ninja from that point forward.

The Day Ninjago Stood Still
While the Ninja train Lloyd, Wu takes his hat off to look at a photograph of him, Garmadon, and Misako. Misako unexpectedly appears behind him and startles Wu. Misako shows him her research and the scrolls containing the prophecy of the Green Ninja.

Moments later, while an earthquake shakes the Bounty, Misako suggests making the NGTV tower an evacuation station for the Bounty to land on. Wu and majority, if not, all, civilians left in the city and the Ninja climb up the stairwell.

Misako loses the container her research was in, and goes back to get it. Once everyone (excluding Misako) is on board, the Stone Warriors start destroying the Bounty's engines, and Wu leaves at the last moment to save Misako as the Bounty flies off.

Misako gets to her research, but at a cost; she is now dangling off the side of a 20-story high stair well. Wu fights his way through the Stone Army and gets to Misako at the last moment and saves her. They are only left with one choice after the Army backs them into a corner. Zane senses that Nya should fly the Bounty downwards, and orders her to do it. Wu and Misako jump off of the building, and land on, to their surprise, the Destiny's Bounty.

Island of Darkness
Master Wu sends the Ninja out to find the Temple of Light while he, Dr. Julien, Misako, and Lloyd stay back to work on vehicles for the Ninja. They complete the vehicles, (the Earth Driller and the Fire Mech) before sending out the Ninja to the Temple. When Lloyd uses the "Golden Dragon," Wu, Misako, Nya, and Julien are watching inside the Bounty and Wu is embraced by Misako.

After the Final Battle
After the Overlord was defeated, Wu acquired Darkley's Boarding School and turned it into "Sensei Wu's Academy," of which he became headmaster and the Ninja, (along with Nya and Dareth) become teachers.

The Surge
Wu takes his students and the Ninja to New Ninjago City where he, Nya, and the students are escorted around Borg Tower by P.I.X.A.L. while the Ninja speak to Cyrus Borg. However, the tour goes awry when the Digital Overlord takes over the systems, turning the machinery against the tour group. They manage to make it out of the building only to find the city under attack by its own security systems. Wu and the Ninja get the civilians to safety, though are easily outmatched by the Security Mechs.

The Art of the Silent Fist
Wu is taken back to Borg Tower where the Overlord probes his memory to find where the Ninja are hiding. Once the Overlord discovers the Ninjas' location, he assimilates Wu into a drone, much like he did to Cyrus Borg.

Blackout
Pythor breaks into Borg Tower where he takes both the hardrive containing the Digital Overlord and Wu to a location in the sewers where he uses the Electrocobrais to power them both. He then sends the now Techno Wu to Ed & Edna's Scrap N Junk where they attack the Ninja.

The Curse of the Golden Master
Techno Wu is sent along with a host of Nindroids by the Overlord to Hiroshi's Labrinth to capture Lloyd, whom they find at the heart of the maze. While Lloyd escapes, Techno Wu battles Garmadon once again. Wu is eventually victorious and captures Garmadon, taking him aboard the Nindroid MechDragon.

Enter the Digiverse
Techno Wu, Pythor, General Cryptor, and the Nindroids break into Borg Tower to stop the Ninja from erasing the Digital Overlord. Wu and the Nindroids break down the lockdown walls in Borg Tower and break in through the savages.

Techno Wu is later seen batting a Nindroid, who lifts his hood to be Master Garmadon. Wu is victorious, but when the Overlord is wiped, he is turned back into Master Wu, and helps save his brother.

Codename: Arcturus
Wu and Garmadon are at The Temple of Light to restore Lloyd's golden power and the Ninjas' elemental powers. Garmadon thinks it is a waste of time because they need balance, but Wu tells him it was Lloyd's idea, not his.

Wu spots Cryptor and Pythor on a satellite, and sends Kai after them, but Kai becomes careless and is taken prisoner by Pythor.

Later, at Borg Tower, Garmadon tells that they defeated Arcturus, an ancient Serpentine General when they were first on each other's side. Wu asks where the Serpentine do their stargazing, and Zane jumps to the answer: The Lost City of Ouroboros.

The Void
Wu returned to Borg Tower with Nya, Garmadon, and P.I.X.A.L. where they were able to contact the Ninja. Advising them that if they "couldn't change their circumstances, they should change themselves", they were able to provide the Ninja help in their attempt to take over the comet-bound ship. However, their communications were discovered by Pythor who lead a squad of Nindroids to attack Borg Industries.

The four managed to escape to Garmadon's monastery and they re-established contact with the Ninja.

The Invitation
Following Zane's memorial, Master Wu requested the remaining four ninja to train at Borg Industries, but only Lloyd came. Upon asking his nephew where the others were, he said the loss of Zane would affect them all and that it would either bring the team together or tear them apart. Wu later appeared at Garmadon's Monastery looking at the plans for the Destiny's Bounty.

Versus
While helping Nya rebuild the Bounty, he fell asleep from listening to her talk about her boy problems with Jay and Cole. He then questioned Misako about contacting Garmadon and the ninja and when she responded she hadn't, he decided to "expand their horizons", to which Nya set off in their backup vehicle the D.B. Express.

Spy for a Spy
He was mentioned by Dareth, who contacted him from the D.B. Express on Chen's Island.

Spellbound
While Misako attempted to contact Dareth and Nya using the computer in the Samurai X Cave, Wu made a pot of tea and offered some to her. In response, she berated him for being so calm when they didn't know where everyone was. Wu assured that he too was concerned, but had faith in Garmadon to guide them.

Winds of Change
Wu decided to retire from being a Master and opened a tea shop - Steep Wisdom - with the help of the Ninja, Nya, and Misako. On the first day of business, Wu sent the Ninja to advertise in New Ninjago City. However, while they were serving their first customer, the Ninja returned and informed him that their elemental powers were gone. At that moment, Lloyd returned from the museum, only possessed by Morro. Wu instantly recognized his former pupil and ordered the Ninja to flee in the Destiny's Bounty.

Ghost Story
Morro soon caught up to them using his Elemental Dragon and knowing that Morro would be relentless until he obtained the staff, Wu made an imprint of the staff's secret message, then threw it off the Bounty to distract his former pupil. Morro however had disabled the ship and 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 Master Yang. Wu ordered the Ninja to head to Stiix while he, Misako, and Nya returned to Steep Wisdom. Once there, he revealed to Nya that she was the Master of Water.

Stiix and Stones
Wu soon began Nya's training to become the Water Ninja, though she insisted she could aid the Ninja just as well being a samurai. Wu pointed out that a samurai was unable to perform Spinjitzu or summon an Elemental Dragon, and he summoned his own as an example. The Master then presented her with the bucket challenge, wherein she had to fill a bottomless bucket completely full of water. This proved difficult for Nya and after trying all day, she gave up. Misako inquired if the day's training was a waste, but Wu noted that she had tossed the bucket into the pond, thus fulfilling her task by doing so.

Kingdom Come
Ghoultar was brought aboard the Bounty and Wu questioned the ghost along with Nya and Ronin. However, when the ghost refused to answer, Wu decided that the time would be better spent training Nya and the two left, leaving Ronin in charge of the prisoner.

Curseworld, Part I
Realizing they needed weapons to defeat the ghosts more than he needed his business, Wu sold Steep Wisdom and used the money to finance new vehicles from Cyrus Borg.

As part of their plan to infiltrate Stiix and destroy the Realm Crystal before the Preeminent arrived, Wu and Misako drove a noodle truck up to the city gate where they were stopped by Bansha. Wu offered Morro one last chance to give up, but he was only met by laughter and thrown into a prison with several of the town's inhabitants.

When the Ninja began their attack, Wu summoned his Elemental Dragon to destroy the prison. He lead the citizens to a waiting ferry where Wu watched to his horror as the Preeminent emerged, Lloyd apparently having failed his task.

Infamous
Aboard the Bounty, Wu meditated with Cole, urging him to find what powers he could unlock as a ghost. The Black Ninja was successful in discovering he could disappear and Wu congratulated him.

Wu later summoned the Ninja to the bridge of the Bounty, informing them that Clouse had escaped the destruction of the Cursed Realm and was heading to Stiix. As the Ninja pursued him, Wu journeyed to the Domu library to figure out what the sorcerer might be after. His research led him to learn of the Teapot of Tyrahn, shortly after which he was ambushed by Nadakhan, the latter seeking to imprison him.

Calmly confronting the Djinn and casually noting Nadakhan's aroma of tea due to his imprisonment in the Teapot, Wu decided to test out his luck by wishing no one would be harmed in their fight, and in response Nadakhan moved their fight momentarily out of the time stream. Satisfied, Wu attempted to defeat the Djinn, but when Nadakhan used his teleportation and speed to evade him, Wu wished to have the power to defeat his opponents. As a result, he became so powerful that he would be able to destroy the planet in a single blow, making any attempts to destroy Nadakhan a disaster in that it would kill everyone else. After pretending to almost sneeze, scaring the Djinn, Wu humbly conceded defeat and wished it all away, being trapped in the Teapot of Tyrahn alongside Clouse.

Public Enemy Number One
While confronting Misako, Nadakhan showed off the imprisoned Wu and Clouse in the Teapot of Tyrahn, before trapping Misako inside as well.

Enkrypted
After receiving the Djinn Blade from Khanjikhan, Nadakhan shattered the Teapot of Tyrahn, transferring Wu, Clouse, and Misako into the blade.

Operation Land Ho!
Inside the Sword of Souls, Wu fell into a deep sleep. He was later awoken by Jay and he and the other Ninja were able to escape from the blade.

The Way Back
Welcoming his students, Wu would proceed to warn them that by defeating Nadakhan, the Djinn's magic would dissipate, causing the reconstructed Djinjago to fall onto everything below, causing untold devastation. Making a plan, he, Misako, Ronin, Skylor, Captain Soto, and Echo Zane headed down to New Ninjago City to help protect the citizens from the inevitable destruction. Later, when Djinjago began to collapse, he and the rest of the citizens watched in horror as the massive debris fell down.

As a result of Jay's final wish erasing the events of the season, Wu was placed back to his original location prior to his visit to Domu, presumably with no memory of what had happened.

Dark Island Trilogy, Part 1
Shortly thereafter, Wu began to feel a sense of overwhelming darkness. At the same time, reports of missing fishermen off the coast of the Dark Island prompted Misako to want to investigate. As Wu sought to meditate on this approaching darkness, he hired Ronin to accompany here.

After meditating at Steep Wisdom for a week, he was interrupted to a villager who had discovered the ruins of Misako's boat, with no sign of here anywhere. Searching the wreck, Wu discovered a note from Misako pleading to stay as far away as possible from the Dark Island.

Ignoring her warning, Wu gather the Ninja at the Samurai X Cave to explain their mission. As the Ninja prepared the bounty, Wu collected an important piece of cargo which Kai and Jay brought aboard the ship.

Shortly after setting off, the Bounty was struck by a lightning storm. In the chaos, all of the Ninja fell off the flying ship though Wu managed to crash it in the jungles of the Dark Island. Upon waking, Wu soon encountered Lloyd fleeing from a group of gorillas he had provoked. After helping the Green Ninja escape quicksand by using Airjitzu, the two returned to the Bounty and spent several days making it seaworthy once more. Although Lloyd wanted to search for Misako, Wu was adamant they sail up the River of Darkness to the Temple of Light.

Dark Island Trilogy, Part 2
As Wu and Lloyd continued down the River of Darkness, the Green Ninja began to become affected by Dark Matter, thrashing out violently when they encountered a swarm of oversized bugs. Although Wu tried his best to keep him focused, it wasn't long before Lloyd jumped off the ship and ran into the jungle to search for his mother, leaving Wu alone on the Destiny's Bounty.

As the river wove it's wave through the Jankikai Jungle, Wu meditated to resist the effects of the Dark Matter himself. Two days after Lloyd abandoned him, Wu was bitten by an infected insect which caused him to hallucinate into confronting a corrupted version of himself.

Following his vision, Wu rested, only sitting up when the Bounty arrived at a mysterious cave. Venturing inside, Wu discovered Clouse who turned out to be the mastermind behind the events on the island. The sorcerer captured Wu and explained his plan to destroy the Temple of Light and corrupt the entire land of Ninjago in darkness. Before Clouse could stop him however, Wu broke free and chased him out of the cave, though escaped in the Misfortune's Keep. Cole found Wu shortly after and explained the situation, though Wu insisted on taking the Bounty to the Temple of Light as it stored his secret tea crate.

Dark Island Trilogy, Part 3
Wu eventually arrived at the temple with the crate aboard the Bounty, and while the Ninja held off the Sky Pirate Crew and Shadow Army unleashed by Clouse, Wu opened it to reveal the Golden Mech. Having had it repaired by Borg following the defeat of the Overlord, Wu piloted it into battle against Clouse, who created his own Shadow Mech to do battle with it. However, Wu managed to overcome his foe, and used the Golden Mech's power to restore the Temple of Light to its original glory. With Clouse's plans foiled, a vortex opened to consume him, and Wu offered his foe help in escaping but was refused, leading to Clouse's imprisonment in the Underworld. Wu and his friends then returned home in celebration, but Wu was soon troubled by visions of old friends...and old foes...

Wu-Cru
Due to the events on the Dark Island, Dark Matter crystals began popping up all over Ninjago and Wu sent the Ninja out to investigate. While at Steep Wisdom, Wu came across a mysterious stranger that had elemental abilities and was somehow resistant to the matter's effects. Worried about the Ninja, Wu asked the stranger to help find them. The stranger agreed and was able to bring back a possessed Zane whom Wu crafted a special tea for to cure the effects.

The Falcon soon arrived having discovered Cole, and Wu sent the Stranger and Zane to retrieve him. Once he was revised thanks to Wu's tea, the Earth Ninja reported that the Serpentine intended to use the Dark Matter to revive the Great Devourer. Although Wu was reluctant to allow the Stranger to continue aiding them, Zane and Cole offered to train it as this mysterious master's immunity to the matter was vital to their success.

After the three returned with Kai and Jay, Wu sent them to the Samurai X Cave to find Nya who had sought shelter there. They soon discovered logs left by Lloyd who had discovered that Fangtom and Pythor were intending to use the Dark Matter to became the Great Devourer, causing Wu to send them to the Mountain of a Million Steps where the old Serpentine Fortress was.

Day of the Departed
On the Day of the Departed, Wu and Misako planned to meet up with the Ninja at the Ninjago Museum of History. When the two arrived, the Ninja were nowhere to be found, prompting Wu to contact the Ultra Stealth Raider and urge the Ninja to hurry up. They eventually arrived and hurried to the gift shop, managing to secure Day of the Departed lanterns before it closed. While Wu was reminding the Ninja of the true meaning of the Day of the Departed, they were greeted by Dr. Saunders. After greetings were exchanged, Wu and the other Ninja followed Dr. Saunders on a tour of the new Hall of Villainy exhibit.

After the tour, Wu and the Ninja parted ways to honor those who had passed from Ninjago into the Departed Realm. Wu used the Destiny's Bounty to travel to the ruins of the Monastery of Spinjitzu where he drank a cup of remembrance tea in honor of his father. However, the Yin-Yang Eclipse that coincided with the Day of the Departed that year allowed Yang to revive several villains, among them Morro, who confronted Wu at the monastery. Wu prepared to battle his former pupil once more, only for Morro to reveal that he had not come to fight. He had instead come to reveal the truth behind Yang's intentions and his plot against the ninja.

Morro and Wu traveled back to the museum and met all of Wu's students except Cole, who had been tricked into bringing the Yin Blade to Yang's Temple; Wu and his students quickly boarded the Bounty to aid Cole, but not before Wu thanked his former pupil who proceeded to return the Departed Realm. Wu and the others arrived at the temple, but due to strong winds they were unable to get close and help Cole physically. However their arrival gave him the inspiration he needed to defeat Yang, who saw the error of his ways and sacrificed his own chance to become human again in order to enable Cole to do so. At Cole's suggestion, Wu and the others then took the restored Temple of Airjitzu as their new base.

Description
Wu is an elderly man with a long white beard. He normally wears a white robe and a conical straw hat. In "The Day Ninjago Stood Still," he is shown to wear a small black skullcap under his hat. Occasionally, he wears a more elaborate white and black kimono with Chinese characters inscribed in gold along the left side. He is rarely seen without his bamboo staff or his tea set. In "Winds of Change," he receives a new outfit which more resembles a Master robe. In "Grave Danger," he gained a battle suit resembling a ninja uniform.

In his youth, he had a full head of blonde hair. As a child, he had a bowl cut, a white tunic with his red symbol similar to his most common attire, and brown pants. As a young man, he had a blonde variant of Jay's hair. He wore a black and white kimono signifying his status as a Spinjitzu Master, with kanji emblazoned on it to be used as a protection spell against evil.

When Wu was assimilated by The Overlord, his appearance changed drastically. His tan straw hat became metallic silver, his arms and legs were black, and his face was half metal, with a red eye. More cybernetics were visible on his torso, and both his staff and his beard were black instead of gold and white.

Age
Wu is several hundreds of years old. He and his older brother's long lifespan is a result of them being the sons of the First Spinjitzu Master, whom lived for thousands of years before finally succumbing to his mortality.

Wu and his brother have a peculiar aging pattern. Ages ago, they were children when Garmadon was bitten, and grew to be young men by the time their father passed away. Their aging stagnated at some point, and centuries later, they were still physically in their late teens during the events of the Serpentine War. Decades later, they were physically in their early thirties when Garmadon was banished, showing that their bodies were still aging, albeit slowly but beginning to quicken. Only a mere decade later, by the time of the events of the series, Wu had become an old men, having aged tremendously in a relatively short period of time due to unknown circumstances.

Personality and Traits
As a young boy, Wu was a bit irresponsible, refusing to retrieve his father's katana after losing it. Instructed by his brother to never put off what can be done today, he would watch, haunted, as the Great Devourer's venom began to corrupt Garmadon as a result of his procrastination, and would likewise remember his brother's words prior to his corruption for the rest of his life.

When he became older, Wu became a more benevolent, generous person, being very reserved and noble and valiantly fighting for good. Having a kind heart, he brought in a homeless orphan named Morro and took care of him, discovering his fatherly instincts after taking in the Master of Wind to be his pupil. However, he also had little patience for wrongful behavior, readily disapproving Morro's reckless actions and unanimously agreeing with his brother to banish the Anacondrai Generals to the Cursed Realm, and being highly protective of his father's name.

Years later, having officially become a master, Wu would develop an incredibly eccentric and mysterious personality, often instructing others with cryptic hints and would often avoid being straight-forward, confusing everyone with his strange methods and ways. Wise because of his years of experience, Wu had an enormous amount of forethought and skilled intelligence, triumphing over several enemies as a result. Incredibly graceful, even when losing, Wu would be willing to sacrifice his life under any circumstances to protect others.

Despite this, Master Wu also had a more silly, playful side. He enjoyed less reserved actions such as food fights and riding on Ferris wheels and had a strange sense of humor even in battle, taking a little fun out of scaring Nadakhan into thinking he was about to destroy the planet and everyone as a result. However, Wu also had a past haunted by his mistakes, echoing his own brother's wisdom, and secretly reprimanding himself for the corruption of Garmadon and Morro.
