Wu is the second-born son of the First Spinjitzu Master and younger brother to Garmadon. A childhood incident led to the latter being bitten by the Great Devourer and slowly infected with evil. When Garmadon left to train with Master Chen, Wu came across the orphan Morro and took him on as a student - which would later turn into his biggest regret. He and his brother were then involved in the first Serpentine War on the side of the Elemental Masters as well as the conflict against the Time Twins. Eventually, Garmadon succumbed to the evil flowing in his veins and tried to take the Golden Weapons, leading to a battle that resulted in Wu banishing him to the Underworld.
Having accumulated much experience and wisdom over the last forty years, he would later seek out the Ninja and become their mentor in order to help them against their foes.
After slowly aging to death, the Ninja were forced to use the time reversal blade on him to save his life. Although they succeeded, Wu was accidentally turned into a toddler because of this, and the Sons of Garmadon kidnap him and Misako in order to use him to get the last Oni Mask. Over time, he gradually ages back to normal, reclaims his father's armor and confronts Garmadon alongside Lloyd.
- Advertised Extra: Despite being in the opening credits for season 4, he doesn't really play a part until the final few episodes. Garmadon is mostly the main mentor for the ninja on that season.
- The Ageless: Not obvious at first, but it eventually turns out he's at least a thousand years old. You wouldn't know it from looking at him.
- Badass Beard: Has a long, flowing white beard. Naturally, it's gone when he's deaged to a toddler, but the first sign of his memory returning in full is that it instantly starts growing back out again.
- Badass Teacher: He is the one who trained the ninjas to be strong.
- Bash Brothers: With Garmadon from Season 3 onward.
- Big Good: He is a wise old man who is also mentor and master to the six Ninja (Lloyd, Kai, Jay, Cole, Zane, and Nya), as he trained them to be capable of protecting Ninjago from evil forces.
- Cain and Abel: With Lord Garmadon. This was briefly inverted during Season 3 after Wu is subject to an Unwilling Roboticisation. Afterwards, this is subverted because Garmadon never wanted to be evil in the first place... and then it's finally played straight again when Garmadon is revived and Wu becomes the only one who can stop him.
- The Chosen One: After being turned into a baby, he becomes the key to the last Oni mask and the true main target of the Quiet One. This is because only someone with Oni blood can remove the last Oni mask. Although The Quiet One ends up improvising and using Lloyd as the key instead.
- Cool Old Guy: Wu's definitely got shades of this.
- Cybernetics Eat Your Soul: He is briefly subject to an Unwilling Roboticisation in Season 3, but gets better.
- Fountain of Youth: As a side effect of the Ninja using the Reversal Blade on him to save his life, and his stealing it to sabotage Krux and Acronix's time machine, when he returns, he's been turned back into a toddler. It takes him 2 whole Seasons to age back to normal.
- Heroic Sacrifice: At the end of season 7, he sabotages Krux and Acronix's time machine, sending them all to destinations unknown. He returns, obviously. Just not in the way the ninja expected...
- Honor Before Reason: While Garmadon had no intention of honoring the deal he and Wu made with Aspheera to teach her Spinjitzu in exchange for her helping them escape the Serpentine kingdom, Wu decided to do it anyway despite his brother's protests. Big mistake.
- Hypocrite: Kai considers him this after hearing the story of Aspheera, pointing out that Wu often tells the Ninja to accept responsibility for their actions, but decided to pretend like what happened with Aspheera never happened.
- In Season 11, Wu wanted the ninja to stop lazing around and to go seek out problems in Ninjago to keep up their skills. They eventually find one alright, and Wu himself is responsible for it.
- A Flashback to his youth in the same season shows that, between him and Garmadon, he was actually the more reckless brother.
- Light 'em Up: His element is Creation, represented by light.
- Light Is Good: Wields the element of Creation, in the form of light, wears white and is the Big Good of the series.
- My Greatest Failure:
- Wu seems to regard Morro as one.
- Season 11 provides another: In his youth, he broke the treaty between the humans and Serpentine by going into Serpentine land, leading to him getting imprisoned and increasing tensions between humans and Serpentine, he then met Aspheera who helped him escape in exchange for him teaching her Spinjitzu. This led to Aspheera usurping the Serpentine king and attacking humans, with Wu stealing one of his father's scrolls of Forbidden Spinjitzu to defeat her. Wu was so ashamed by all this that he wanted to just forget all about it.
- Nice Job Breaking It, Hero: Teaching Aspheera spinjitzu was not his best decision.
- Not So Above It All: Many times, he joins in with the ninja and their joking, even occasionally making a few at his students expense.
- Obsolete Mentor: Laments that he is becoming this in Season 13, due to not contributing much in the previous two seasons. He gets over it as the season progresses with help from Cole and Vania, becoming more passionate and adventurous than ever.
- Old Master: Along with Garmadon, they're some of the oldest living people in Ninjago. This is thanks in part to their Oni blood, which extended their lifespans.
- Parental Substitute: To the Ninja and Lloyd. He also used to be Morro's Parental Substitute.
- Pretty Boy: Much like Garmadon, Wu seems to have been a looker as a teenager / young adult.
- Rapid Aging: His fight with Krux gets him subject to a Time Punch, which makes him start aging to death. The ninja spend most of the season trying to save him.
- Red Eyes, Take Warning: During his tenure as Evil Wu thanks to the Overlord.
- Secret-Keeper: It's pretty much a running gag that Wu seems to know what the latest threat is, but never just freaking tells the ninja about it before it's actually a problem, and when he does start to tell them, something usually interrupts before he can share the main deets. Come season 8, Jay's gotten a little tetchy about it.
- Simple Staff: His primary weapon is a bamboo staff. He looses this staff come Season 5.
- Something Only They Would Say: The ninja realize "Cole Jr." is someone they recognize first when he shows an insatiable fondness for tea, but then says "ninja never quit".
- Spot of Tea: Wu likes his tea. It's pretty much all he drinks when he's a baby and a toddler, which clues the ninja that it's their master.
- Unwilling Roboticisation: Subject to one in Season 3, but he gets better.
- Unwitting Instigator of Doom: In Season 11: Insisting that the Ninja seek out a new adventure lead to the return of Aspheera, Kai losing his Elemental powers, and Zane being banished to the Neverrealm.
Garmadon is the first-born son of the First Spinjitzu Master and older brother to Wu. He was infected with evil by the Great Devourer as a child, and its influence grew on him throughout his life until he became a full-fledged villain. Before he succumbed fully to the evil in his blood, he fell in love with a woman called Misako and married her, at some point conceiving their son Lloyd. He was eventually banished to the Underworld as a mutated figure, and assumed leadership of the Skullkin Army. He plotted to return and collect the Golden Weapons and reshape Ninjago in his own evil image. After facing the Ninja for the first time, Garmadon escaped and became more powerful.
His villainy culminated in him being unwillingly possessed by the Overlord. In a final fight with Lloyd, the Overlord was defeated and exorcised from Garmadon along with all the evil in his blood, leaving him a normal human being again. Garmadon then takes up mentorship as penance for his evil, trying to and eventually failing to take a pacifist path. Catching his son trying to sneak off to a tournament with the Ninja, Garmadon joined them, knowing their host only too well as his evil former sensei, Master Chen. Garmadon did his best to protect Lloyd during the tournament, and finally sacrificed himself to stop a second Serpentine War.
Season 8 has him brought back from the Cursed Realm by his worshipers, The Sons Of Garmadon. Unlike before, Garmadon was brought back with only the worst traits of himself, making him completely different from even his former evil self.
- The Atoner: From Season 3 onward. Not anymore come Season 8, after being resurrected by the Oni Masks.
- Back from the Dead: The Sons of Garmadon seek to bring him back from the dead as Lord Garmadon and succeed.
- Bad Boss: Is this to both the Serpentine (though this was more of a case of Surrounded by Idiots) and to the Sons of Garmadon (this being a You Have Failed Me case).
- Badass Pacifist: Has sworn to never fight after pulling his HeelFace Turn. This doesn't stick past season 3.
- The Bad Guy Wins: So far he's the only villain that has ended a season victorious more than once.
- The pilot episode. He knows Samukai will betray him, so when Sensei Wu takes the Sword of Fire into the Underworld, he has Samukai take the other weapons there. This is because when Samukai does betray him, they will create a singularity which will allow Garmadon to escape the Underworld.
- In Season 1 he ends up getting the 4 golden weapons, killing the Great Devourer and achieving his revenge, allowing him to put his plans into motion.
- Happens again when the Sons of Garmadon bring him back at the end of Season 8, as he successfully defeats the Ninja and conquers Ninjago with none to oppose him.
- Being Evil Sucks: Due to being evil due to it literally running through his veins, so he'll always be forced to be evil, but he's aware of this and doesn't truly want to be, particularly where his son is concerned. Gets worse when Lloyd is revealed to be The Chosen One. After Garmadon is resurrected by the three Oni masks, being evil doesn't suck for him because he no longer has a conscience. Even then, however, he still shows signs of regret and remorse when he is fighting Lloyd one-on-one, suggesting that he is unhappy with being revived as a destroyer but has essentially given in to his fate.
- Big Bad: He's the driving threat behind the four part pilot, given how he sent the Skulkin to retrieve the Golden Weapons. After forming an Enemy Mine with the Ninja in Season 1, he returns to this spot in Season 2, at least for the first half, and becomes The Heavy for the Overlord in the second. He also serves as the Greater-Scope Villain and Final Boss of Season 8 (though not of his own free will), and stays the Big Bad of Season 9.
- Big Bad Ensemble: In Season 9 he antagonizes Ninjago as Emperor Garmadon, with his opposition being the Elemental Masters, Nya, Misako, PIXAL, Dareth and Lloyd. Meanwhile the original 4 Ninja and a de-aged Wu are up against a new villain, The Iron Baron, due to the fact that the Ninja are stuck in another realm.
- Body Horror: Multiple times: glowing eyes, charred skin, four arms, the draconian form the Overlord forced him into, and finally an Anacondrai body, courtesy of Master Chen.
- Jay lampshades this by eventually telling him to pick a body and stick to it!
- Brought Down to Normal: The Overlord's defeat caused all of the evil to vanish from his body.
- But Now I Must Go: His fate at the end of March of the Oni.
- Came Back Strong: When he is resurrected in Season 8, he is able to wield the power of Destruction. After unlocking his True Potential by defeating his son Lloyd he is able to use Creation as well.
- Came Back Wrong: The Sons of Garmadon sought to invoke this by reviving him using the three Oni Masks. They were successful. While he does manage to get back to fighting strength, all the good in him is gone, and later episodes suggest there's a few memories missing, since he doesn't even recognize a picture of himself.
- Card-Carrying Villain: In Season 1, he literally eats evil for breakfast. It's low on carbs.
- The Comically Serious: Occasionally, after his resurrection, especially when he teams up with the ninja. Guy has no idea how to interact with ordinary people anymore. It's both silly and saddening at the same time.
- Dark Is Evil: He has a black color scheme and is, of course, evil. When the Devourer's venom is purified from his body, he appears as an ordinary elderly man wearing a green gi.
- Dark Is Not Evil: Despite his compulsion to be evil thanks to the Devourer's venom corrupting him, he is more of a Tragic Villain because he doesn't WANT to be evil, he just can't help himself. His black and purple color scheme comes from his time condemned to the Underworld by Wu.
- He also had a suit with a Red and Black and Evil All Over asthetic before being fully corrupted by the venom
- Darth Vader Clone: Badass Baritone? Black color scheme? Wears a helmet? The father of the Messianic Archetype? The Heavy who's actually The Dragon to the actual primary antagonist? ... Definitely qualifies. His redesign in The LEGO Ninjago Movie and by proxy, Season 8, gives his armor and helmet a greater resemblance to Vader.
- Death Glare: He wants Traveler's Tea. The tea shopkeeper tells him that only fools ask for that. Cue the Death Glare.Mistake: (nervous laugh) But you're no fool.
- Demonic Possession: Becomes the Overlord's unwitting vessel.
- Demoted to Dragon: To The Overlord in the (original) final story arc.
- Enemy Mine: In Season 1 he teams up with the Ninja to oppose the Serpentine, and save Lloyd.
- Even Evil Has Loved Ones: Never stops putting his own life on the line to save Lloyd.
- Evil Is Petty: In season 1, even when he's working with the ninja, he's still a colossal jerk. And again during season 10, when he shuts off the Destiny Bounty's engines while they're in mid-flight just because.
- Evil Makes You Ugly: He used to look like an ordinary person, albeit with pale skin as the Devourer's venom worked on him. It wasn't until Wu knocked him into the Underworld that he took on his distinctive all-black, red-eyed look.
- Evil Old Folks: Albeit an tragic variant. Before his HeelFace Turn, he intended to reshape Ninjago in his own evil image.
- Evil Parents Want Good Kids: "Once Bitten, Twice Shy" reveals that he didn't want Lloyd to follow in his footsteps.
- Evil Sounds Deep: Played straight when he's trapped in the Underworld, averted after he escapes where his voice is actually quite high. Zigzags a little with his resurrection in season 8, depending on his mood.
- Evil Versus Oblivion: He joins the ninja team temporarily in Season 1 to prevent Pythor and the Snake Tribes from unleashing the Great Devourer. He's also the one who deals the final blow to the Great Devourer with the Golden Weapons. And again with the Oni during season 10.
- Foil: Seems to be set up as one to his brother in season 4. Whereas Wu acts more the part of the enigmatic, weird, slightly aloof mentor towards the Ninja, Garmadon is the actual father of one of them and is much more hands-on, direct, and pragmatic as the Ninja's sensei. He also knows quite a lot more about the criminal underworld than his brother does, naturally.
- Good Is Not Nice: As one of the good guys, Garmadon is quite pragmatic, although he's not above pushing the Ninja towards amending their behavior towards fellow Elemental Masters, even if they are on opposing sides.
- Good Parents: Never stops trying to be as good a father for Lloyd as he can be. He remains this post HeelFace Turn.
- Grumpy Old Man: Towards the Ninja in season 3, and with good reason.
- HeelFace Revolving Door: As Lord Garmadon, he typically switches to face only when Lloyd is in trouble. It helps he's not evil of his own accord.
- HeelFace Turn: Turns back into a (good) human upon the defeat of the Overlord.
- Heroic Sacrifice: At the climax of the season 4 finale, he trades places with the Anacondrai generals to allow them to deal with Chen's army. As such, Garmadon ends up trapped in the Cursed Realm with no way home; and is ultimately killed one season later when the entire Cursed Realm is destroyed (along with all its inhabitants).
- Hoist by His Own Petard: He is defeated by Lloyd in season 9, who uses the very same Martial Art that he had beaten him with back in Season 3 (The Art of the Silent Fist) to exhaust him into defeat.
- I Have No Son!: Said verbatim to Lloyd after he comes back wrong thanks to Harumi. It's what solidifies that the revived Garmadon is nothing like the man Lloyd knew when he was alive, not even when he was Lord Garmadon before.
- "I Know You're in There Somewhere" Fight: A couple of times, with Lloyd. The first time, it's when Garmadon is possessed by the Overlord and Lloyd is trying to reach him, and the second time it's when he's brought back by Harumi without any of his positive qualities. Lloyd is able to reach him the first time, but it doesn't work so well when he tries it again, because the Lord Garmadon Harumi brought back is nothing like the man who he knew in life.
- Knight of Cerebus: His appearance from Season 8 onward has him devoid of any humorous moments unlike his previous incarnation.
- Late-Arrival Spoiler: He becomes a good guy for two whole seasons before dying. Also, since the entire premise of Season 8 is that the villains want to resurrect him back as Lord Garmadon, the fact that he dies is pretty much announced to newcomers on a megaphone if they watch the trailers or keep up with the show at all. Likewise the fact that he has returned to life as Lord Garmadon and taken over Ninjago is announced in the Season 9 trailers.
- Made of Evil: Thanks to the Great Devourer biting him in his youth, it's literally in Garmadon's blood to be evil. In the Season 2 finale, he is finally cured of this after Lloyd beats the Overlord.
- Morality Pet: Even once Lloyd joins the Ninja's side and becomes the one destined to defeat him, he refuses to target him, instead targeting the rest of the Ninja. The fact that the resurrected Garmadon is able to harm Lloyd, physically and emotionally, without any semblance of remorse shows that his revived form really is devoid of his good qualities, just as Harumi predicted.
- Multi-Armed and Dangerous: His dark form caused him to grow a second pair of arms, each for holding the remaining two golden weapons.
- Nominal Hero: The citizens of Ninjago City didn't hesitate to give Lord Garmadon credit for destroying the Great Devourer, never mind that he did it for revenge and kept the Four Weapons of Spinjitzu for his own purposes. He becomes a real hero eventually, though. The fact that he killed the Devourer as Lord Garmadon is Harumi's motivation for wanting him to come back in such a state, so the creators did get around to lampshading this eventually.
- Not Me This Time: The ninja initally think Garmadon is the "Treacherous Deceiver" responsible for Aspheera's rampage in Season 11. He's not. The real culprit is none other than Wu.
- Obviously Evil: As Lord Garmadon, he's pitch-black, with glowing red eyes, visible ribs, and a face like a demon or monster from traditional Japanese artwork. This gets worse when he gets a second pair of arms.
- Only Sane Man: Once he's human again, his down-to-earth personality contrasts with his brother's Cloud Cuckoo Lander antics of previous seasons.
- Papa Wolf:
- Very much so, he brought an entire army to protect his son. Even after he becomes the Big Bad again, he refuses to let any harm befall Lloyd.
- After Pythor and the Overlord kidnap Lloyd, he goes against his vow of peace to fight them.
- In season 4, he joins the Ninja on a quest just to protect Lloyd — and how.
- No longer a Papa Wolf in Season 8, in which his revived and corrupted form is able to harm Lloyd with no semblance of remorse.
- The Power of Creation: The Mega Weapon he obtains at the beginning of Season 2 has this ability. However, he can only use it once a day and it drains his energy severely with each use.
- Really Dead Montage: Occurs for Lloyd after Garmadon plans to be traded for the Anacondrai generals in the Cursed Realm. Various memories of father and son play along with pretty background music while Lloyd fights Chen's army in a flurry of fury.
- Red Eyes, Take Warning: As a dark lord, he was this in the pilot and in the first season.
- Silver Fox: Garmadon as a middle-aged sensei is basically what his attractive-for-a-Lego-minifigure son will look like in a few decades.
- Stern Teacher: Is this to Lloyd in Season 3. He's tough on him to get him to reach his full potential, but it's made 100% clear he's only doing it out of concern for his son. He's much more accessible as a sensei in Season 4.
- Team Dad: In Season 4, he becomes the Ninja's hands-on sensei while his brother and his wife repair the Bounty back home.
- Tragic Villain: Unlike some villains, Garmadon does not want to be evil. Luckily, he breaks out of it only to be dragged back into it from beyond the grave by the Sons of Garmadon.
- The Unsmile: During season 10. He tries to genuinely smile, but Lloyd tells him it just looks like he's plotting stuff.
- Unwitting Pawn: Was manipulated by the Overlord into destroying the balance, all so the Overlord could take his body.
- Villainous Breakdown: At the end of the Ninjaball Run, when the Ninja just won't quit and finally win the race, foiling his latest plot.
- Woobie, Destroyer of Worlds: It's hard to deny that he's this. He was forcibly made evil thanks to being bitten by the Great Devourer and now has to fight his own son.
- Yin-Yang Bomb: Combines his own dark power with the Golden Weapons to destroy the Great Devourer. After he is revived in Season 8 and unlocks his True Potential, he is able to wield Destruction and Creation in tandem.
Jay's very eccentric, yet loving parents.
- Amazingly Embarrassing Parents: At first, including commenting on Nya right in front of Jay, or telling all his friends about Jay's potty training.
- Badass Driver: They prove to be this in "Ninjaball Run."
- Body Horror: Get bitten by the Fangpires and not only affects them, but their creations.
- Good Parents
- Muggle Foster Parents: In case you wondered why Jay is an Elemental Master while neither of them ever were...
- Screw This, I'm Outta Here!: This is invoked during Season 3, where they casually leave the ninjas behind using jetpacks while nindroids ambush the scrapyard, though they did believe they could handle it. Jay asked for a jetpack, but they don't have one for him because he hardly visits them.
- Serious Business: Edna's pretty concerned about keeping hydrated at all times, carrying a bottle of water in her purse. She also takes the time to yell about the merits of hydration while being abducted by Vermillion Warriors.
An elderly lady that owns a tea shop in Ninjago. She has knowledge of all sorts of brews, including the dimension hopping Traveler's Tea. In Season 9, it is revealed she is an Oni.
- Bunny-Ears Lawyer: Acts very nutty at times, but she does definitely know her stuff.
- Cool Old Lady: Knowledgeable about all sorts of teas and history, and not afraid to talk smack to her customers.
- Defiant to the End: Facing a pissed-off Garmadon, she shows absolutely no fear.
- Humanity Is Infectious: Was originally sent by her fellow Oni to bring back the First Spinjitzu Master, but instead grew to love the world of Ninjago.
- Killed Offscreen: The last we see of her, she attempts to fight Garmadon so that Skylor can escape. When we cut to Skylor again, she overhears Killow say that "they don't need to worry about the old lady anymore" implying Garmadon killed her.
- Last of Her Kind: Is the only confirmed living Oni so far. This later turns out to be anything but true.
- Really 700 Years Old: As an Oni, she has lived far longer than many of the characters in the series, being centuries old.
- Token Heroic Orc: Much, much nicer than any other Oni.
- Voluntary Shapeshifting: Is able to change her appearance thanks to being an Oni.
Cole's father, a singer with the Royal Blacksmiths.
A cocky kung-fu "Sensei" who allows the Ninja to train Lloyd at his Dojo, entitled "Dareth's Mojo Dojo." He is revealed to have lied about his kung-fu claims.
- Blessed with Suck: An oni grants him powers which seem to be inducing Potty Emergency in himself.
- Cowardly Lion: He's not much of a fighter and never one to leap into trouble, but does look after his students and willing to defend them if need be. Likewise he can usually be counted on for aid if the ninjas need it.
- Dumbass Has a Point: Jay tries to use the fact that the Ninja saved the city from the Great Devourer as leverage to train at the Dojo, only for Dareth to point out that Garmadon's the one who actually defeated the Devourer.
- Epic Fail: After seeing Lloyd easily destroy ten boards with an elemental chop, he attempts to do it himself with FIFTY boards. He barely has to hit it without screaming in pain.
- The Load:
- His attempt at stopping the pirates only causes more problems for the Ninja and Lloyd is forced to save him.
- In the Season 2 finale he averts this by accidentally putting on the Helmet of Darkness, giving him control of the Stone Army.
- He averts this again by saving the students from a shark attack.
- During the Tournament of Elements, he gets brought along by Nya only because he'd have blown her cover, and is only there because of an all-consuming desire for a food Chen discontinued from his chain. He proceeds to reveal she's only the island by (accidentally) broadcasting his rock'n'roll via her van's loudspeakers, and when he gets caught, automatically scuppers a plan the Elemental Masters had formulated to escape the workshop just by showing up (the plan relied on using the sewers, which Zane had determined would've been just able to take everyone's weight.)
- Aaaand again during season 9, where he inadvertently gives Harumi a chance to bust free, scuppering the plan to have Skyler steal Garmadon's powers, and causing the death of Mistake.
- And averted once more in the "Hunted" finale, where he successfully fights off a group of Garmadon cultists. Sort of. Just not in the way he'd actually intended.
- Moment Killer: Just as Kai and Skyler are about to kiss in the season 4 finale, he interrupts to whine about Puffy Pot Stickers.
- Speaks Fluent Animal: Manages to get two sharks to back off.
- Sixth Ranger: He tries hard to make himself part of the ninja by calling himself the Brown Ninja.
- Trademark Favorite Food: Guy is obsessed with Chen's Puffy Pot Stickers. He wouldn't have gotten involved in the events of season 4 if not for that obsession.
- You Are Fat: Not said, but during the Tournament of Elements, his fondness for Puffy Pot Stickers means he's got a noticeable pudge, despite being a minifigure.
Zane's father, or rather, his creator.
- All There in the Manual: His name has never been revealed in the show, but is mentioned in the LEGO Ninjago Character Encyclopedia.
- Back from the Dead: In "The Last Voyage", the Ninja find him on a prison tower in the middle of the ocean and learn that on his deathbed, he was revived by Samukai so he could design vehicles for the Skeleton Army. It only kept him alive for a little while longer, as he was still frail and weak, and he passed away in the Time Skip between seasons 2 and 3.
- Gadgeteer Genius: His achievements include Zane, the Falcon, and a guardian robot, all of which he built from a small workshop in the Birchwood Forest. Later, after being brought back from the dead, he helps design the vehicles for the Skeleton Army. After he is rescued he builds a Power Driller for Cole.
- Killed Off for Real: Eventually, his age catches up to him and he dies of natural causes, he may have been revived with a magical potion but he had already died once of old age and the potion didn't restore his youth.
Lloyd Garmadon's mother and Garmadon's wife.
- Action Mom: She can fight as well as she can teach. She manages to walk away from a fight with the resurrected Garmadon, who'd just pulverised Lloyd, with only assistance from Nya.
- Berserk Button: DON'T imply she's old. Wu learned this the hard way.
- Daddy Had a Good Reason for Abandoning You: So she claims, though Lloyd is still (and understandably) hurt by it.
- Lady of War: Finds herself dragged into the midst of the battle between ninja and the Overlord.
- Love Triangle: With Lord Garmadon and Sensei Wu.
- MayflyDecember Romance: Unless there's something she's not sharing, Garmadon has a serious age gap on her, being at least a thousand years old, while she's just an ordinary human.
- Never Mess with Granny: Vague Age notwithstanding, she has graying hair and looked about the same age as Lord Garmadon and Sensei Wu in Wu's photograph. And yet she is amazingly agile, knows Spinjitzu, and has more expertise on the prophecy of the Green Ninja than Sensei Wu himself.
- Put on a Bus: Is absent at the beginning of season 8, having left to go looking for Wu. She returns in episode eight. She's gone again in season 11, but returns in season 13.
- Skunk Stripe: Her hair is mostly grey, save for a small streak of white in one lock.
- Vague Age: Exactly how old she is exactly isn't clear. Wu makes the mistake of suggesting she's elderly at the beginning of season 13. He very quickly regrets it.
- Wrong Guy First: When looking at a picture of herself and Lord Garmadon when they were young, she tells Sensei Wu that "I should have chosen you".
- Ascended Extra: She started off as just "Zane's Girlfriend" and more or less became a main character by seasons 8 or 9.
- Barbie Doll Anatomy: Doesn't have any breasts to speak of whatsoever, which is good, because she typically has a lot of chest exposed.
- Battle Couple: With Zane after he :gives her half of his power core. Together, they can use Spinjitsu.
- Chekhov M.I.A.: Suddenly disappears from Zane's CPU partway through season 7, and by the end of the season still hasn't reappeared, only to pop up after the time skip in season 8 once again working with the ninja without comment. Subverted when it turns out she actually was the new Samurai X all along.
- Dropped a Bridge on Him: Early on in season 4, she turns out to have been abducted and her body destroyed by Chen's cultists, offscreen, after the end of season 3.
- Fun with Acronyms: Her name stands for Primary Interactive X-Ternal Assistant Life-form.
- Grappling-Hook Gun: Has a built in one in her arm.
- Heroic Sacrifice: She helps the ninjas use the EMP to deactivate the nindroids, but it deactivates her as well. Fortunately Zane revives her by giving her half his power core. Her body eventually gets scrapped permanently, but luckily Zane is able to save her by downloading her processor into himself, turning her into a Voice with an Internet Connection. Presumably, Borg could build her another body if given the chance, but he hasn't got around to it. Sometime in season seven she gains a new body as Samurai X.
- Love Interest: She shows interest in Zane and they have some tender moments with each other.
- Mission Control: Takes up the role for the ninja in season 8, when she's not being Samurai X.
- Red Eyes, Take Warning: When she was under the Overlord's Control. Normally, they're green.
- Retgone: Momentarily during the finale of season 7, though nobody notices.
- Ridiculously Human Robot: Though she's a downgraded version of the robot you've seen already.
- Sixth Ranger: Starts tagging along with the ninja after she's revealed to be the new Samurai X.
- Took a Level in Badass: When she's reactivated after her Heroic Sacrifice, she becomes a better fighter thanks to having part of Zane's power core in her. She takes another as the new Samurai X.
- Voice Changeling: Manages to throw off Nya's suspicions about her identity as Samurai X using one to hide her actual voice.
- Voice with an Internet Connection: Becomes this after Chen's henchmen scrap her body. Zane installs her processor into his upgraded body to save her.
The head of Borg Industries and the creator of P.I.X.A.L. He is brilliant scientist who helped rebuild Ninjago City into the technologically advanced New Ninjago City.
- Brainwashed and Crazy: The Overlord takes control of him after he gives the Ninja the Techno-Blades.
- Cool Chair: He was disabled from birth, so he built his moving chair.

- Cybernetics Eat Your Soul: What the Overlord did to him.
- Electronic Eye: Gains a few after his Unwilling Roboticization.
- HeelFace Turn: Once he's freed of the Overlord's control, he becomes a true ally to the ninjas.
- Prophetic Name: He jokes that when his parents named him, his career choice was set.
- Put on a Bus: He's absent from season 4, aside from a brief appearance in "The Invitation" and a voice cameo in "The Corridor of Elders". He returns again in season 5.
- Tragic Villain: Converted to a cyborg against his will by the Digital Overlord.
- Unwilling Roboticisation: The Digital Overlord forcibly converts him into a cyborg. Luckily it's reversible (Heck it ended up happening twice in the 3rd season).
- Unwitting Instigator of Doom:

- One of his information bots helps clue Nadakhan in on where to find the Realm Crystal and regather his crew.
Ronin is a selfish yet skilled thief and bounty hunter, whose deal with the Soul Archer caused him to become involved in the Ninja's conflict with Morro and the Ghost Army. Initially siding with whoever he thought would save his skin, Ronin eventually returned, fully committed, to help fight the Ghost Army alongside the Ninja at the Battle of Stiix. Ronin returned later on, as more of a neutral party.
- Anti-Hero: At first glance, Ronin is a selfish yet skilled thief and bounty hunter. He often took terrible actions, making deals with the evil Soul Archer and selling Zane to Master Chen. However, looking to change his ways, Ronin sided with the Ninja, and oversaw Nya as she tried to master her water element. This proves that he has an sympathetic backstory, as his motivation for in the game was actually to save his cursed soul. Eventually, his more sincere personality comes through in the episode, "Curse World: Part 1," when he arrives in his airship R.E.X. and promptly dumps every amount of money he ever made on the building Morro had lifted with his elemental wind power, giving Lloyd the chance to defeat Morro. From that point on he is the Ninjas' friend and ally... aside from helping arrest them all in season 6.
- His villainous side finally takes prominence (in-canon) in The Island, having tricked the Keepers with an animatronic Wojira so they would send all their valuables to it for offerings, which he could then turn a profit off of.
- Badass Normal: Despite lacking the elemental or magical powers that most of the other characters have, he's still very capable and intelligent, and frequently proves to be a formidable opponent for the main characters when the moment presents itself.
- His feats in the non-canon Shadow of Ronin deserve a mention: Nearly wiping the ninja of all their memories, not only recruiting an army of samurai but brainwashing the Serpentine to both work for him, then uncoverirng the long-lost, ancient Elemental Forges and Primal Fulcrum to attempt to open a portal to the Cursed Realm and unleash Master Chen and his Anacondrai cultists back upon Ninjago, all so he can get money to pay his debts.
- Big Bad Ensemble: Ronin is the fake Wojira in The Island, tricking Mammatus into offering him gifts.
- Though non-canon, his first appearance in Shadow of Ronin certainly puts him on an equal footing with most other season-long villains with the danger threshold he creates.
- Captain Ersatz: Without his hat and mask, he is visually similar to Snake Plissken.
- Easily Forgiven: Despite all the crap he does, no one seems to hold much of a grudge against him. It helps that at the least he can be a dependable ally if things get serious.
- Cool Ship: R.E.X.
- Follows it up with the Salvage M.E.C. in the Dark Island Trilogy and Day of the Departed.
- Guest-Star Party Member: Jay recruits him for the final fight of season 6, and he ends up saving him and his family from a tight spot in Day of the Departed.
- HeelFace Turn: He becomes an ally of the Ninja in Season 5.
- HeelFace Revolving Door: Of course, he could easily turn on them if there's a chance to earn a quick buck as shown in Seasons 6 and 14.
- Only in It for the Money: He isn't interested in power, just money. It is eventually revealed that he needs so much money due to a debt he has towards Soul Archer.
- Also the reason why he was terrorizing the Keepers with a ship shaped like their deity so he could have them surrender their gold to him.
- Wild Card: Though he considers himself to be a friend of sorts towards the Ninja, he will oppose them if offered a high amount of money.

The prototype of Zane found in the basement of Dr. Julien's lab.
- Easily Detachable Robot Parts: Not intentionally, mind. His disrepaired state means his arms and legs will fall off at a moment's notice, usually at the worst time.
- Guest-Star Party Member: Jay recruits him for the team in the final fight of season 6.
- Replacement Goldfish: Jay and Nya figure Dr. Julien made him as a replacement for Zane.
- Smart People Play Chess: Or try to, but he goes up against an enemy who cheats, and never figures it out.
Kai and Nya's parents, and the original Elemental Masters of Fire and Water.
- The Bus Came Back: Both return in season 15.
- Daddy Had a Good Reason for Abandoning You: They were forced to forge armor for the Vermillion Warriors under the threat that Krux would harm Kai and Nya if they refused. This left them absent from their children's lives for many years.
- Depower: Since they passed on their elements to their kids, they have no power of their own anymore.

- Put on a Bus: For all the fuss about finding them in season 7, they've just been unheard of for seven seasons straight.
A famous explorer known for his many past exploits.
- Adaptational Jerkass: This version of Clutch Powers is a lot more arrogant, selfish, lazy and less adventurous than his original series counterpart, only exploring the discovered pyramid in Season 11 when the Explorers Club threatens to cancel his membership because he hadnt done any exploring in over a decade. He gets worse in season 14 as he tries to commit outright plunder by stealing the Amulet from the Keepers.
- Canon Foreigner: He originates from LEGO: The Adventures of Clutch Powers.
- Catchphrase: "Gumdrops!"
- Dirty Coward: Chose to run and hide rather than help the ninja deal with Aspheera. He does so again when Kalmaar shows up, but the other members of the Explorers Club are more than willing to help.
- Eyepatch of Power: Though it's actually fake.
- The Friend Nobody Likes: Hes not very liked by the other members of the Explorer's Club.
- The Ghost: Was offhandedly mentioned by Cole in Season 1. He finally makes an onscreen appearance in Season 11.
- Hate Sink: As explained in Adaptational Jerkass, this version of Clutch has very little resemblence to his original counterpart and, despite being labeled the ninja's "ally", seems to exist for the sole purpose of creating problems rather than solving them.
- In Name Only: He is Clutch Powers by name. Personality? Not so much.
- It's All About Me: One major example is found in the Ninjago: Reimagined short "Sweatin' to the Goldies" reveals his musical movie has a number about him singing about how awesome he is.
- The Load: Turns out to be this in season 14 as his attempts to steal the Keepers' Amulet only lands the ninja in more trouble...
- Miles Gloriosus:...which doesn't stop him from telling stories about his heroism back at home.
- Nice Job Breaking It, Hero: His stealing of the Storm Amulet and bringing it back to Ninjago City allowed Kalmaar to easily steal it to control Wojira, which leads to Nya's Heroic Sacrifice.
- Pet the Dog: Then again, he does show up at Nya's memorial, visibly saddened.
- We Have Become Complacent: How good an explorer he used to be is not made clear. But what is made clear is that he has spent some time coasting on his fame and riches. He only agreed to help the Ninja in their expedition so he could keep his Explorers Club membership, and struggles during the trip, due to being sorely out of practice.

He was trapped inside the game when Unagami heard him say he wanted a bigger challenge and invited him in.
- And I Must Scream: He's been trapped inside Prime Empire for decades. The fact that he has only one life left means he can't afford to take any risks that would cause him to lose it, which doesn't help his situation either.
- Heroic Sacrifice: Gets cubed by Red Visors trying to help the ninja escape when his hideout is discovered. He gets better.
- Knight in Sour Armor: Having been trapped in Prime Empire for a very long time, Scott becomes overly cautious and bitter, as he chooses to remain on the sidelines due to having only one life remaining before he'd be "cubed".

However, when the Ninja reveal that Okino is the part of the video game, he becomes disillusioned with the fact. But he still intends to help the Ninja after they encourage him to do the right thing.
- Sadistic Choice: Unagami gives him one: Okino can either leave the ninja to die at the hands of the Red Dragon and be able to journey to the real world, or he can keep helping them and be unable to ever travel there. Fortunately, he chooses the latter.

A team of adventurers hired by King Vangelis years ago to investigate the dungeons of Shintaro and retrieve the Skull of Hazza D'ur, only for them to be betrayed and cast deep beneath the mountain. They join forces with Cole and the other ninja to help take down the Skull Sorcerer. Their team consists of Korgran the warrior, Fungus the sorcerer, Plundar the thief, and Adam the giant spider.
