Wu Tomoki

Master Wu is the wise, elderly mentor of the ninja and the Master of Creation. He is the First Spinjitzu Master's second-born son, Garmadon's younger brother, Misako's brother-in-law, and Lloyd's paternal uncle. Wu grew up learning the art of the ninja alongside his older brother, Garmadon, who was infected with evil. They fought together as a team against evil for countless years, until Garmadon's corruption completed and he was subsequently banished to the Underworld.

Around a decade later, Wu trained a group of teenagers in the ways of Spinjitzu so they could protect the land his father created. Wu guided the ninja in many battles against his brother, the Serpentine, and the Overlord. When the Nindroid crisis began, Wu was corrupted into a cyborg but was purified after the Digital Overlord was vanquished. After the ninja went to a mysterious island to save Zane, Wu joined the Elemental Masters to fight Chen and his Anacondrai Cultists.

After Garmadon was banished to the Cursed Realm and the close of the Second Serpentine War, Wu's first pupil, Morro, escaped the Cursed Realm. Wu trained Nya to harness her element, allowing her to destroy Morro's master. Shortly after, Nadakhan ravaged Ninjago and trapped Wu in the Sword of Souls, though these events were undone by Jay's final wish. On the Day of the Departed, Wu was met with a revived Morro, who helped Wu reunite the ninja during Yang's scheming. Wu later confronted Acronix, who struck him with the Forward Time Blade that caused him to rapidly age. Though his health was restored by the Reversal Time Blade, he sacrificed himself in a bid to defeat the Time Twins and was lost in time. The loss of Wu left Lloyd in charge of the ninja, and they made it their goal to find Wu.

A year later, he was found turned into a baby due to his exposure to the Reversal Time Blade, and kidnapped by the Sons of Garmadon until he was rescued by Cole. Little Wu was with the original four ninja aboard the Bounty when they were almost crushed by the Colossus, until they used Traveler's Tea to save themselves, ending up in the Realm of Oni and Dragons. Marooned, he grew up again while helping his students to fight Iron Baron and the Dragon Hunters and find a way to return to Ninjago. After Iron Baron's defeat, Wu proves himself worthy to receive the Dragon Armor from the Firstbourne. He became the Dragon Master and used the Firstbourne to get himself and his four students back to Ninjago in time to help Lloyd, Nya, and those left behind to end Garmadon's rule and take down the Colossus. Sometime after the battle, he returns to his normal age and reclaims his place as the ninja's teacher. Sometime after, he was present in the arrival of the Oni. He aided his brother and students in performing the Tornado of Creation to vanquish the Oni.

Months after battling the Oni, Wu's past comes back to haunt him yet again when the ninja inadvertently released the Serpentine sorceress, Aspheera, who knew Wu as the Treacherous Deceiver, from her thousand-year imprisonment. Once Zane is banished to the Never-Realm after saving Wu from a blast from Aspheera's staff, Wu's attempt to go after him alone is thwarted by the ninja, and he is left behind with P.I.X.A.L. in Ninjago. They attempted to go after them by using Traveler's Tea, but inadvertently release the Preeminent from the Departed Realm. P.I.X.A.L. was able to defeat it in battle and send it back. Soon after, he reunited with them, including Zane.

Wu eventually aided Zane and P.I.X.A.L in finding Milton Dyer while the ninja sought Unagami inside Prime Empire. With Jay and Dyer successfully converting Unagami, Wu was able to reunite with the previously cubed ninja, resurrected along with all the other inhabitants of Prime Empire.

After the ninja freed the trapped gamers, Wu started to feel left out and think that the ninja no longer needed him. He was then forced by Misako to accompany the ninja to the Kingdom of Shintaro. Adventuring with Cole, Vania, and the Upply, Wu rediscovers his role as mentor when he encourages Cole to never give up when things seem hopeless. After Cole defeats the Skull Sorcerer, Wu is reinvigorated and steers the Destiny's Bounty in search of he and the ninja's next adventure.

He travelled with Misako and Clutch Powers' group to the Island of the Keepers but was captured by the Keepers. He was later rescued by the ninja.

Later, he would send the ninja down to see the energy pulse that has been disrupting Nya's powers. He asked Kai and Ray to stay to study masters of Fire. He is warned by Cole that the Storm Amulet had been stolen. He, Cole, Kai, Ray and Misako confronted Clutch Powers only to meet Kalmaar and his crew attempt to stop Kalmaar from leaving with the amulet, only to fail as Kalmaar awakens Wojira and Wu witnesses as Nya merged with the sea. He later fights Maaray Guards as Jay battles Kalmaar, he is disappointed by Nya leaving the team and speaks in the memorial.

Appearance
In his youth, he had a full head of blond 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 teenager, he had long hair tied in a bun and had a brown headband. He had three freckles on his left cheek at the time. He wore a conical straw hat on his head. His clothes consisted of a white shirt with a red lotus symbol and sand-brown pants with brown belt and sandals.

As an older teenager/young adult, he had a blond variant of Jay's original hairstyle. 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.

Currently, he is an elderly man with a long white beard. He normally wears robes and a conical straw hat. In "The Day Ninjago Stood Still," he is shown to wear a small black skullcap under his hat, being bald underneath. He can be seen without this skullcap in "King of Shadows," "The Art of the Silent Fist," "Wasted True Potential," "Awakenings" and "The Prodigal Father," but he wears it once more in "The Real Fall" (the reasons for missing this skullcap are explained in Trivia section).

His original outfit consisted of simple white robes and pants. Once, he wore the more elaborate white and black kimono from his youth, 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 wears a long, gold sleeveless vest over a white robe. In "Grave Danger," he gained an ornate suit. From Season 11 onward, he has different white robes with a pale brown cape, a large red sash around his waist, sideburns connected to his beard, beige-colored pants, reddish-brown boots covered in linen, and he has grown a single braid of white hair, similar to his father.

When Wu was assimilated by Pythor, his appearance changed significantly. 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 beard were black instead of gold and white respectively.

When he was struck by the Forward Time Blade, Wu began to rapidly age. A notable change to his appearance was his beard, which grew long enough to touch the ground when he stood up. This was later reversed when Nya cured him with the Reversal Time Blade.

Overtime, the effects of the Reversal Time Blade had turned him into a baby, but as the effects wore off, he slowly grew back into his normal age. As of the end of Season 8, he was a toddler with very short legs and wears beige footie pajamas and hoodie.

By the beginning of Hunted, Wu had regrown to his child self, wearing beige clothing, with a tear on the lower right side of the jacket and one on the back. He is also seen wearing a brown pilot's helmet. When he grows into a young teenager, Wu's hair has grown and been tied into a bun, now with a golden headband. He looks similar to his young design from the past, albeit with white hair and slightly bushier eyebrows. He wears a sleeveless version of his Dragon Hunter disguise, with new pants and black gloves. Wu later aged further into an older teenager and had grown a mustache and a goatee. In a fight with a hunter, Wu gained a new conical straw hat and slightly resembles his older self. Once he tamed Firstbourne, he wore golden robes under the Dragon Armor. After some more time, he became his old self again.

He currently wears a white kimono with a golden dragon symbol on his back and a red belt. He has black pants and brown shoes on his feet, while he has white bandages on his knees to strengthen his legs. He has a slightly darker straw hat on his head and wears a long sand-brown cape. During the battle for Shintaro Mountain, he wore straw armor and wooden shoulder pads.

Age
Wu is thousands of years old. He and his older brother's long lifespan is a result of them being the sons of the First Spinjitzu Master, who also lived for thousands of years before finally succumbing to his mortality. According to Mystake in "Two Lies, One Truth," this is due to their Oni blood.

After returning from the Temporal vortex, he had been found reverted to a baby due to his exposure to the Reversal Time Blade. However, as the effects of the blade wore off, he rapidly grew back to his normal age over the course of several weeks. By Season 9's beginning, he had become his child self again, grew to a teenager, and eventually his normal self by the end.

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 a millennium later, they were still physically in their late teens during the events of the Serpentine War, as Garmadon stated in "Only One Can Remain" that he was Lloyd's age while training under Chen. Around three decades later, they were physically in their early thirties when Garmadon was banished. Only a mere decade later, by the time of the events of the series, Wu had become an old man, having aged tremendously in a relatively short period of time due to unknown circumstances.

For possible explanations on Wu and Garmadon's seemingly rapid aging, see the Trivia section.

Personality
As a young boy, Wu was a bit irresponsible and impulsive. Because of this, Wu nearly started a war between the Serpentine and the humans. However, after Wu and Garmadon stole the Scrolls of Forbidden Spinjitzu, Wu became a more benevolent, satisfied, and generous person, being very reserved and noble and valiantly fighting for good.

This as a result, led to Wu refusing to retrieve the katana he lost while he was sparring with Garmadon. Instructed by his brother to never put off until tomorrow 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. 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, 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 straightforward, 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 and playful side. He enjoyed less reserved actions such as food fights, dancing, and riding on Ferris wheels. 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, and for not telling Misako about how he felt about her. When turned into a baby, Wu often cried, but laughed at something funny to him, and he enjoyed being held by Cole. When he grew into the size of a toddler, Wu starts being helpful, even using the motto that "Ninja never quit," but he is still portrayed at having laughter. He later did a drawing, albeit badly, of Mystake's tea shop sign as advice for the ninja. Upon becoming a child again, Wu displayed both his previous attitude as a child and as an adult. After turning into a teenager, Wu regained some of his maturity and some of his memories help him in using his wisdom. However, he gained an impulsive side as he chose to lie to Faith about the Dragon Armor since he needed a way to keep hope in his friends. When confronted by Faith, he had to admit his lie but he was happy to see it actually contained truth as they discovered a map for the armor. He was also willing to steal Dragon Hunters' clothes if it could help save the ninja. He was giving up quickly in activities he couldn't do, like when he couldn't use a Chain Rifle. He also didn't understand how the ninja could joke in threatening situations, although after Jay's explanation, he began joking with them. After aging further and growing a mustache and a goatee, Wu regained all his memories and his full wisdom returned. Wu was ready to defend his friends as he did in the past and did so by standing defiant towards Baron. Wu also wanted to protect them and did so by agreeing to lead Baron to the Dragon Armor while assuring his protesting pupils. After Baron failed to control the Firstbourne, Wu showed a darker side of himself to Iron Baron, revealing that while his students helped teach him responsibility, Baron taught him the power of lies. Wu revealed that the Dragon Armor could not, in fact, control the Firstbourne, and he watched, near emotionless, as the Firstbourne encased Iron Baron in molten lava. After returning to his actual age as an old man, Wu appears to have regained his normal personality. Wu also doesn't like when the ninja are lazy and is willing to set insidious traps to teach them a lesson. He can also be quick yo anger if his student want help from him before thinking for themselves. After Zane's disappearance in the Never-Realm, he was very sad and blamed himself. After the attack by Unagami, he began to feel his old age, and although he admitted that he enjoyed many adventures, he realized that the ninja had become independent and no longer needed him. Later, after talking to Vania, however, he realized his mistake and realized that the ninja still needed him. His desire for adventure returned and he was determined not to return home but to go wherever the wind takes them.

When he thinks, he strokes his long beard. He has a similar habit even though he suspects something bad, but then he only runs his hand over his mustache.

Weapons



 * Bo staff: Wu predominantly uses his father's bo staff as a means of a weapon and is shown to be extremely proficient in handling it. After Morro stole the staff, Wu stopped using the staff, but acquired a new one later. A few months after Oni's invasion, Wu acquired a new staff that was not made of bamboo, but of ordinary wood. He had three more such staff in his room in the monastery.
 * Katana: As a young boy, he learned to fight a katana, which he later used to fight Garmadon in the Realm of Madness.




 * Time Blades: During the Battle for All of Time, Wu and Garmadon used the Time Blades to fight the Time Twins. After twins use their element of Time, these blades absorbed this ability, and Wu and Garmadon used Time for a short time.
 * Golden Weapons: During the battle between brothers, Garmadon broke Wu's staff, so he used the Scythe of Quakes and Shurikens of Ice to fight his brother. About a decade later, he used the Sword of Fire to fight Samukai and proved to be a skilled warrior with him.
 * Sacred Flute: Wu was also good at playing a Sacred Flute, as he was able to stop the Hypnobrai with its melody.




 * Chain Rifle: During his stay at the Realm of Oni and Dragons, Faith taught him and the stranded ninja how to use Chain Rifles. Although Wu's shooting from this weapon did not go well at first and he gave up quickly, he later learned to use this weapon so well that he helped the Resistance defeat the Colossus.




 * Dragon Armor and its weapons: After claiming the Dragon Armor and the Dragonbone Blade, Wu wields the latter with extreme proficiency, along with the Dragon Shield. During a standoff with Garmadon after Lloyd is incapacitated by the former, Wu uses it against Garmadon, and reveals that the blade can hold back his destruction and creation powers.
 * Trident: During Kalmaar's assault on Ninjago City, Wu used a trident against the Maaray Guards.

Powers

 * Spinjitzu: Like his brother, Garmadon, Wu has the ability to perform Spinjitzu, with his version channeling the power of Creation.
 * Forbidden Spinjitzu: Using Forbidden Spinjitzu, he becomes much more angry and dangerous, while his strength increases and he uses energy waves much more.
 * Screenshotter--NEW111-8’25”.jpg Elemental essence of Creation: Being the Master of Creation, he can use the power of Creation and create something out of nothing, although he rarely uses his ability, because this power must be used with care and wisely knows not to overuse it.
 * Energy wave: He can knock opponents into the air by hitting the ground with a wave of the Creation energy.

Abilities

 * Ninjago--(Ep.89-2)--1’11”.pngSkilled warrior: Having many years of training from his father, the First Spinjitzu Master, and combat experience alongside his brother, he is an expert warrior, skilled in hand-to-hand combat, and the use of many weapons, preferring his signature bo-staff and occasionally the katana. He is especially good at stick-fighting. Despite his advanced age, he is proficient enough at combat that he can fight and take on skilled warriors like Morro, the Time Twins, and several Dragon Hunters. While they were out-of-shape, he could defeat all six of his current students at once with ease through pure skill alone.




 * Fishing: He is very good at fishing and has often been with his father, brother, or both to fish when he was a child.
 * Swimming: He is good at swimming, as he and Garmadon often went swimming to the lake when they were children. He was also seen swimming when he, Cole, Vania and the Upply tried to get out of Rock-Bottom.
 * Holding breath: He can hold his breath for a really long time as when he waited for Zane inside the frozen pond.
 * Climbing: He is good at climbing tall mountains as when he climbed the tallest mountain to meet Cole.
 * Long lifetime: Having inherited his father's Oni ancestry, Wu has lived much longer than a pure-blooded human, being thousands of years old, like his older brother.
 * MoS4NinjaDoor.pngSummoning his dragon: Although he rarely uses this ability, he is able to summon his dragon using the power of Creation.

Artistic

 * Origami: He is able to make a bird from a paper that really flies and flutters its wings.
 * Drawing: He seems to be good at drawing with ink.
 * Hand shadows: He seems to be good at creating various shapes, such as eagles, with his hands as the shadows.

Dragons

 * Master Wu Dragon
 * Wu used it during the time of Morro's return and the ghost invasion.
 * It first appeared in "Stiix and Stones."
 * Chompy
 * Although Chompy belongs to Princess Vania, Wu rode on him in "The Son of Lilly."
 * He first appeared in "The Skull Sorcerer."

Carriages

 * Wu's horse carriage
 * Wu had the other ninja haul him in his horse carriage to the Caves of Despair for the Scythe of Quakes.
 * It first appeared in "Weapons of Destiny."

Mechs

 * Golden Mech
 * While originally the First Spinjitzu Master and Lloyd's vehicle, Wu had the mech rebuilt and used it to combat Clouse on the Dark Island.
 * Wu first used it in Dark Island Trilogy, Part 3.

Boats

 * Wu's ship
 * Wu and the ninja traveled on his ship to the Frozen Wasteland for the Shurikens of Ice.
 * It first appeared in "King of Shadows."

Hovercrafts

 * Hover Hunter
 * As Techno Wu, he used it to reach Hiroshi's Labyrinth.
 * It first appeared in "The Art of the Silent Fist" although it wasn't used by Techno Wu until "The Curse of the Golden Master."

Balloons

Etymology
The meaning of a Chinese name Wu is military, martial or affairs, business.

Behind the scenes

 * Wu's mouths comparison.png has no last name, as his first and only name is "Wu."
 * According to the Hageman Brothers, Wu was based the general mentor character archetype rather than any one specific character, though he may have been somewhat inspired by Mr. Miyagi from The Karate Kid franchise.
 * Paul Dobson's original voice for Wu "was deemed politically incorrect," so his lines were rerecorded. However, the original version of a line in "Weapons of Destiny," "Father would not want you to do this, brother," was left in the final episode by mistake.
 * Dobson's current voice for Wu was based on the common mentor character archetype from martial arts movies he had seen in the past.
 * Because "Sensei" has different meanings in different countries that could possibly cause issues in the future, since 2016 the usage of the word has ceased, and been replaced by "master." Because of this, Wu is now "Master Wu." Officially, this extends to other characters referred to as "Sensei."
 * Wu was first referred to as "Master Wu" in The Realm of Shadows, then in the Dark Island Trilogy, and in the show for the first time in the 2016 fall special, "Day of the Departed."
 * According to Tommy Andreasen, this change was made because of the movie and it is "probably a cultural thing."
 * Up until "The Jade Princess," Wu had a three-dimensional mouth. Now his mouth is two-dimensional, like every other character.
 * According to Tommy Andreasen, WILFilm had decided to make Wu's mouth three-dimensional, and Andreasen went along with it.
 * Screenshot 20200427-170940.jpg reason why Wu's mouth has been two-dimensional since Season 8 is probably due to the as a result of WilFilm's animation update in some way since the Season 8.
 * In seasons 1 and 2 he also has three-dimensional eyebrows.
 * Due to his baby/toddler and child forms in the eighth and ninth seasons, Wu has had the most voice actors of any character in the show, excluding P.I.X.A.L.'s many voices in "Secrets Discovered."
 * The LEGO baby piece included with the Tribal Woman from Minifigures Series 15 represents Wu's first baby form, while his second form is represented by the baby figure introduced in a LEGO City set, 60134 Fun in the park - City People Pack.
 * The hood Wu wears as a baby resembles Wyldstyle's from The LEGO Movie, while the unhooded version he wears as a child resembles Wyldstyle's unhooded version as well.
 * As a teenager in Hunted, Wu uses the headband and top knot hairstyle introduced on Cole in The LEGO Ninjago Movie.
 * He is similar to several mentor characters from other franchises.
 * He is similar to Obi-Wan Kenobi and Yoda from Star Wars, the three of them being masters. Both Wu and Obi-Wan trained a boy who happened to be the "chosen one" and the son of their brother/close friend who turned to the dark side (the son being Luke in Star Wars and Lloyd in Ninjago, and the brother/close friend being Anakin and Garmadon respectively).
 * He is similar to Iroh from Avatar The Last Airbender, because they are both older men who are the uncles and masters of one of the main characters (Lloyd and Zuko), they love tea, they opened their own tea shop (Steep Wisdom and Jasmine Dragon) and they are the brothers of one of the main villains of their show (Garmadon and Ozai).
 * He is similar to Albus Dumbledore from Harry Potter because they are both extremely old and experienced men with long white beard and hat on their heads, and both have brother and supernatural abilities. Both were also school principals at some point in their lives.
 * He is similar to Gandalf from The Lord of the Rings, because they are both several thousand years old and experienced men with white beards and hats on their heads who have supernatural abilities, they hold staff in their hands, and at some point in their lives they seem to have been killed. Their clothes are also white in later point of their life.
 * He is similar to Shifu from Kung Fu Panda, as they are both experienced martial arts masters who were betrayed by their first students (Morro and Tai Lung), who were found abandoned. They both raised and trained them, but when Morro and Tai Lung learned that they were not chosen (Green Ninja and Dragon Warrior), they wanted revenge on their masters before they were imprisoned. Both also trained the chosen one (Lloyd and Po) in martial arts to stand up to the forces of evil. Both also thought in their youth that they would become the chosen, although they later realized that they were destined to protect them.
 * He is similar to Mr. Miyagi from The Karate Kid: both saved the original protagonist (Kai and Daniel LaRusso) from skeleton-themed villains (Skulkin; Johnny Lawrence and his gang) early in the first installment; both taught lessons that were not as they seemed (Wu's training course turned out to have taught the ninja Spinjitzu; Miyagi's techniques of "wax on, wax off," "sand the floor," etc. taught Daniel martial arts moves); both had a past brotherly relationship with a villain (Garmadon and Sato Toguchi) who was redeemed toward the end of the second installment; and both had a romantic connection to the same woman (Misako and Yukie).
 * The shoulder pads of Hero Wu were originally used for the Frightening Knight from LEGO Minifigures.
 * Despite the fact that small dots symbolizing a growing stubble appear on Teen Wu's face in the sets, it does not appear in the show.
 * This face was later used on a pirate minifigure from LEGO Ideas, Tattooga.
 * This face is later used by Kaito.
 * Original young Wu's hair exists in physical form on the Race Car Driver from LEGO Minifigures: Series 3 and original child Wu's hair exist in physical form on child Lloyd from 71741 Ninjago City Gardens.
 * When Wu fights the ninja on the roof of the monastery in "Wasted True Potential," for a moment his hat flies into the air and shows Wu's head, which is missing his black skullcap seen in previous episodes. This is likely because characters are no longer shown with studs on their heads as of Season 10, so a covering for the top of Wu's head is no longer needed, animation-wise.
 * This is also seen in one gif and in "The Prodigal Father," but in "The Real Fall," Wu has this skullcap again. This is presumably because was missing his hat for a longer time in the latter episode, so his skullcap may have been added back in order for him to look more normal.
 * Wu also didn't have this skullcap in "King of Shadows." This was probably because it was not yet created.
 * The reason why Baby Wu wears a hood and doesn't have his head exposed like on a physical piece of LEGO is probably so that the stud would not be visible on his head.
 * As a baby, Wu is one of the few male characters to have a female voice actor, the others being Lloyd (from Seasons 1 to 7), Brad, Gene, Skales Jr., Leroy, Sammy, and Ginkle.
 * There are several differences between the SotFS Wu minifigure and his version of the show. His legs are black instead of dark brown and his boots are only brown. The white fabric is also slightly lower and the red fabric has a gold band in the show.
 * Hero Wu has unique legs in the show, while his minifigure recycles SotFS legs. The legs are almost the same, but they lack red fabric. There is also no red fabric on the torso on the physical minifigure, and the spines on the shoulder pads are not beige, but brown. While in the set his arms are sand brown, in the show they are white.
 * In 70643 Temple of Resurrection, Baby Wu is included, but it is not written on the box and he is mentioned only in the description of the set as a mysterious baby.
 * Unlike all other released babies as LEGO figures, Baby Wu does not have a classic piece of baby's body, but two connected studs. This is probably so that it can be put in the backpack that Cole has on his back.
 * He is the character with the largest number of theme songs in the whole show, as he has one as an old man, one as a tired master in Season 7, one as a baby and one as a teenager.

Trivia

 * Wu is the first main character shown in the series.
 * When he was a child, he often fell asleep with a lamp because he was afraid of the dark.
 * He is right-handed.
 * Even as a baby, Master Wu loved to drink tea. This was noted by Cole in "Dead Man's Squall" after trying to feed him milk as tea seems to be the only thing that he wants to consume.
 * According to the Hageman Brothers, Wu's favorite tea is "HumiliTea."
 * In "Wu's Teas," his favorite tea is white tea.
 * According to Tommy Andreasen, Wu's Creation power is not an Elemental Power. If so, this would mean that his Master Wu Dragon is not an Elemental Dragon. However, the 2016 Character Encyclopedia calls it "Elemental Creation Dragon" in the page's subtitle, and Andreasen later referred to it as "Wu's elemental dragon."
 * The tricks he did in the pilot episodes—changing the ninja's clothes and seemingly conjuring a tea cup out of thin air—were simply tricks, not uses of his power.
 * Wu is one of nine Elemental Masters that have facial hair.
 * The other eight are Bolobo, Karlof, Neuro, Gravis, Jacob, Jay (in the future) and the Time Twins.
 * Wu and Bolobo are also the only ones who have a beard as a physical piece.
 * Wu has the most known near-death experiences of any character in the show:
 * He almost fell into Torchfire Mountain when he fell off the Bounty, but was saved by the ninja.
 * He was eaten by the Great Devourer, but managed to survive.
 * He was struck by the Forward Time Blade by Acronix, which caused him to rapidly age until death, but was later cured by the Reversal Time Blade.
 * During his ascent with Cole, Vania, and the Upply, Wu fell off the mine cart that he was on, but was saved by Korgran.
 * His first student was Morro, although the Master of Wind eventually left and never came back due to his frustration at not being the Green Ninja.
 * Even before Morro, Aspheera learned Spinjitzu from Wu. Later Misako and the ninja also learned it from him.
 * Wu is the second person known to escape the temporal vortex with the first being Krux, who had done it 40 years earlier. However, unlike Krux, Wu escaped the Time Rift one year after being lost in time, whereas Krux escaped the Time Rift after an indefinite period of time.
 * His staff is revealed to be his father's staff in "Winds of Change."
 * The staff also contains clues to the location of the Tomb of the First Spinjitzu Master from three symbols; the Airjitzu symbol, the Sword of Sanctuary symbol, and the third one defines the First Spinjitzu Master's Tomb.
 * It's also revealed that Wu didn't know about those symbols prior to Possession.
 * It is revealed in "The Quiet One" that the baby is actually the infant version of Master Wu; due to the circumstances in "Lost in Time," the Reversal Time Blade did more than just restore him to his normal age, it also reversed him through his years of life, rendering him in the form of a baby.
 * Wu is the second character to be rapidly aged, after Lloyd and the fifth character to be de-aged, after the four original Ninja.
 * He is the second character to be human but having cyborg body parts, the first being Cyrus Borg, and followed by the Mechanic, Iron Baron, Daddy No Legs, and Arkade.
 * However, as the only one, he did not cause permanent damage and parts of the cyborg were removed after the demise of the Digital Overlord.
 * From Season 3 to Season 9, Wu has the most changes in appearance: his old form, techno form, baby/toddler, child, teen/young adult in the past, young teen, and older teen with a mustache and goatee.
 * After returning back to his old form in "Green Destiny," Wu wore the same outfit he had in the pilot and first four seasons.
 * Though he appeared to have his old memories as a toddler, Wu lost them when he grew into a child. After becoming a young teenager, he started regaining them.
 * In "Saving Faith," he regained all of his memories.
 * Since Garmadon unlocked his True Potential and gained the power of Creation, it is possible that if Wu was to unlock his own, he would gain Destruction, the opposite of his brother.
 * Wu had blond hair in the past, when he was young, both as a child and as a teenager/young adult. In Season 9, he had blond hair as a child, but white hair as a teenager. According to Tommy Andreasen, the reason for this could have been Wu growing up under different circumstances.
 * He knows the secrets of Forbidden Spinjitzu in The Book of Spinjitzu, but the secret was covered and hidden in his journal.
 * In Harumi's data file on Wu in Garmadon Rulez!, Harumi speculates that he could be potentially as powerful as his brother.
 * He survived much longer than Ray did after he was hit by a Time Punch, indicating that even though he is already extremely old, he still has a very long amount of time left in his lifespan before he will die from old age. However, Ray may have simply been struck by a harsher Time Punch. This could also be because he is part Oni, and simply lives longer because of this.
 * From Seasons 1 through 7, Wu is the character who introduced the episodes: both number and title.
 * According to Tommy Andreasen, there are three possible reasons for why Wu and Garmadon aged so quickly between "Battle Between Brothers" and the beginning of the series, despite having been young for so long.
 * In an interview with Brent Miller, he hinted it had to do with Wu and Garmadon being apart from each other and from the Golden Weapons, as Garmadon was banished to the Underworld and Wu hid the weapons shortly after.
 * In the live-chat of an episode of the Eljay Johnsen Show, he confirmed that one reason may be that Wu and Garmadon share an intrinsic connection of some sort that was severed by Garmadon being banished, affecting their mortality.
 * He also said another explanation could be tea.
 * The reason Garmadon and Wu were designed to look much younger in "Battle Between Brothers" is likely because at that time, the idea of Lloyd's character did not exist, so there was no need for a shorter time gap between Garmadon's banishment and the beginning of the series. A description from a 2011 LEGO Club Magazine supports this, stating that Garmadon had been gone for thousands of years.
 * Wu trained two students who later became antagonists before they redeem themselves. The first being Morro, who left due to his desire to be the Green Ninja, but redeemed himself by giving Wu the Realm Crystal at the cost of his life and helped tell the ninja about Cole on Day of the Departed. The second being Zane, who was banished to the Never-Realm and became the Ice Emperor due to Vex erasing his memories, but redeemed himself by recovering them, incapacitated Vex, and destroyed his scepter.
 * He is the fifth villain (in his Techno form) that knows how to do Spinjitzu, the others being Garmadon, The Overlord, Aspheera, and Doubloon.
 * His and Wooo's name are homophones.
 * However, the Ghost Ninja Wooo's name was only mentioned in the sets.
 * Wu doesn't appear in the sets of Tournament of Elements, Prime Empire, The Island and Seabound.
 * During Season 4, Garmadon takes on the role of master.
 * In the shorts Wu's Teas, Wu seems to lack seriousness and seems to be more goofy and lighthearted.
 * He also turns out to be sleepwalking and sleeping with a teddy bear.
 * He was the official leader of the team before Lloyd became the leader. It was thought that Cole was the leader, but this was never official.
 * In original concepts for "Rise of the Spinjitzu Master," Wu, after seeing Misako and Garmadon reconcile, would walk away with the Overlord manifesting inside him as the screen faded to black.
 * Wu watches old ninja movies on a VCR.
 * Despite wearing the same suit for the first four seasons, Wu's original variant was only available in the sets for the pilot episodes.
 * His appearance is the opposite of his brother, because Wu has long beard and no hair, while Garmadon has no beard and has hair. Wu's main color is white, while Garmadon's is black.
 * Wu has several mantras and catchphrases told to the ninja throughout the series or quoted by the ninja and attributed to him.
 * "Never put off until tomorrow what can be done today."
 * "The best way to defeat your enemy is to make them your friend."
 * "Iron sharpens iron."
 * "It's not the size of a ninja in a fight, it's the size of the fight in the ninja."
 * "Change anything, change everything."
 * "If you want something bad enough, you find a way to make it happen."
 * "We are defined by what we value, not valued for how we are defined."
 * "Grief takes many shapes and forms. Some sing and dance, some climb mountains."
 * "Holding onto anger is like trying to throw a hot rock. Only you get burned."
 * "Adventure does not come to the idle, it comes to those who seek it."
 * In 2020, Tommy Andreasen asked fans on Twitter to come up with new "Wu-isms," also writing some examples of things Wu could say:
 * "Sharpen your mind – it is the most powerful weapon you will every wield."
 * "Find your balance – only then will you know if the World around you is crooked."
 * "An able body with no moral compass will fall hard!"
 * After he disappeared, Lloyd stuck posters to see if anyone had seen him.
 * In Chapter 6 of Way of the Departed, it stated that Misako pins photos everywhere. This may alternatively be referring to the types of photos seen on the Bounty from Season 8: Sons of Garmadon onward, as the chapter states she put up photos of friends and family in addition to Wu.
 * He is one of the ten characters to have a cape in the sets, the others are Lloyd, Chen, Morro, the Time Twins, Harumi, the Blizzard Sword Masters, Akita, and Mammatus.
 * During the show, Wu alternated several hat colors, including light sand-brown (most of his performances), silver (Techno Wu), gold (Battle Wu), brown (Teen Wu) and sand-brown (since Season 11).
 * Since Season 11, his appearance is much more detailed and his clothes are much less white.
 * Wu's most common outfit is the white kimono he wears in pilot episodes, the first four seasons and Season 9. The second most common is the SotFS outfit he wears in seasons 11, 12, 13, and The Island.
 * Wu sometimes sneaks off to ride the Spinning Teacups in the Mega Monster Amusement Park.
 * The books Wu has on his reading list in the Library of Domu are:
 * Mastering Your Bamboo Staff: Attacks and Defense
 * Spinjitzu Tornado Techniques
 * Tasty Tea Recipes: An Ancient Handbook
 * Guide to the Serpentine Tribes
 * Mustache Maintenance for Beginners
 * The Art of the Silent Fist
 * Legends of the Temple of Fortitude
 * Despite the fact that Wu has a braid on the cover of The Book of Spinjitzu, he started having it in the show only as of Season 11, two years after the publication of the book.
 * Wu appears to remember the events of Season 6: Skybound even though they were undone and his memories were erased. He wrote about the events in The Book of Spinjitzu and seems to be the one who had the Ninjago history murals painted. According to Tommy Andreasen, Jay and Nya may have told him about the events.
 * His hat has an interesting ability, because even in a dangerous situation, when the hat would definitely fall, it stays on his head. However, if it falls in some cases, it will return on his head, as shown in "The Real Fall."
 * In the WildBrain animation, the hat is also more often seen slightly skewed or jumps during combat sequences, as can be seen, for example, during the return of the ninja from the Never-Realm in "Awakenings" or on gifs for Season 11.
 * During his life he visited many legendary fabled kingdoms and claims that once you've seen one, you've seen them all.
 * According to Jay, he is like living fortune cookie because everything he does is a puzzle meant to torture the ninja.
 * His beard appears differently in the show than in the sets, because it swings when moving and is not bent to the side but falls straight down.
 * Naturally, the neck attachment section of the beard is not present on Wu in the show, but it can be seen on his silhouette at the beginning of "Rise of the Snakes."
 * His beard takes the shape of the physical version in "Can of Worms," when Kai is poisoned by Venomari venom, later in the Season 7 intro and the intro for the first half of Season 2.
 * Wu has always known Jay was adopted, as he referred to Ed and Edna as Jay's "foster parents" in his journal in the Dark Island Trilogy, and he knew Jay's mother in the time of the Serpentine War.
 * CGI image of Hero Wu used on the poster for seasons 12 and 13 or in the image for NINJAGO: A Musical Journey he has a cape, which does not appear in the show or on the physical minifigure.
 * It is unknown where Baby Wu got his clothes in "The Quiet One" or how it was possible that it suited him even though he was a child.
 * As shown in The Island, Wu can place his staff under the cape on his back, just as the ninja can place weapons on their backs.
 * He was seen sleeping many times throughout the show. While in "Wrong Place, Wrong Time", "Island of Darkness" and "Into the Dark" he slept with a hat on his head, in "The Hatching," "A Time of Traitors" and "Scavengers" he slept completely without a hat, probably because he did it all day, not just at night.
 * He was also seen sleeping in Wu's Teas, where he was sleepwalking.
 * "Into the Dark" is the only episode where Wu covers his face with a hat.
 * He also fell asleep standing in "Versus," when Nya explained him her problem with Cole and Jay.
 * He was also sleeping in sitting in "Pause and Effect" and "Nyad."
 * He was also sleeping as a baby in "Dead Man's Squall" and as a teenager in "The Gilded Path" and "The Weakest Link."
 * Although in pilot episodes or Season 1 he said he was old, indicated that he was weak, and had a horse carriage or he could ride with Nya the Samurai Mech, in later seasons he did not like being called old, for example, in Season 5, when Nya called him old, he said it didn't mean he is weak. In Season 11, the ninja also call him old, to which he will be told that they are simply afraid of him. His character also changed, as he was a little more eccentric in the first seasons, for example when he danced with the ninja in pilot episodes or he ate cotton candy or was amazed by a ferris wheel at Mega Monster Amusement Park. He also laughed a lot more and had fun with the ninja. He almost always had his hand behind his back when walking and was slightly hunched over.
 * It's possible that two major turning points for individuals who would ultimately become Wu's enemies were caused by Wu's negligence involving various katanas. These moments would be Garmadon's corruption by the Great Devourer's venom, as seen in "Tick Tock," and Morro's fall to darkness after discovering he was not the Green Ninja, as seen in "Ghost Story."
 * Wu is the only character to appear in every Destiny's Bounty set, including Land Bounty, except 71749 Final Flight of Destiny's Bounty.
 * As shown in "The Kaiju Protocol," Wu didn't know what the Never-Realm looked like, as he mistook it for the Departed Realm.
 * He has a dislike for coffee.
 * He prefers traveling the old-fashioned way—on foot.
 * Cole's voice actor, Kirby Morrow, once jokingly said "Cole's best friend is Sensei Wu. Nobody knows, but we have this whole secret thing where Sensei Wu and I actually, we go and fish on Sundays, and we talk about all sorts of things, mostly about how Zane is not very good at ninja moves."
 * In recent years, Wu and Cole have been grouped together throughout various points in the story, specifically in seasons 8, 9, and 13.
