Kai, the Red Ninja
The Red Ninja and Master of Fire. Kai was once a blacksmith and owned a small shop with his sister Nya originally run by their late father. When the Skulkin Army took Nya hostage, Kai was forced to master Spinjitzu and eventually teamed up with the other Ninja to seek the four fabled weapons of Spinjitzu to stop Lord Garmadon.

- Deconstructed and subverted in Season 4. A point is made that Kai can be self-focused and overall disappointed that he's not The Hero, didn't do the Heroic Sacrifice before, and wasn't The Chosen One. The Big Bad himself also tries to exploit this fact to try and draw Kai to his side, though it fails. Finally, throughout Season 4, his story has the most focus.
Jay, the Blue Ninja
The Blue Ninja and Master of Lightning. Jay was raised in a junkyard with his parents, Ed and Edna, whom he eventually abandoned and journeyed to Ninjago City to test his inventions, which ultimately failed. However, Sensei Wu saw the Lightning within him and trained him with Cole and Zane at the Monastery, eventually meeting Kai and joining forces to find the Golden Weapons of Spinjitzu. Being the fastest of the Ninja, he learns Spinjitzu at the Caves of Despair, and helps the others learn it as well.

Zane, the White/Titanium Ninja
The White Ninja and Master of Ice. Zane has no memory of his past or his parents, being a homeless orphan all his life. Sensei Wu found him "testing himself" underwater, however, and seeing the Ice within him, brought him to the Monastery to train with the others. After apprehending Lord Garmadon and defeating the Skulkin Army, he uses the Shurikens of Ice in battle and keeps the Ice Dragon, whom he names Shard. Gifted with a sixth sense, Zane appears to have the wisdom to tell the future, and is the wisest and stealthiest of the Ninja. However, his odd behavior and lack of humor makes him the target of the others' jokes, which Zane usually doesn't understand. But then something very stunning reveals the truth behind his past and personality. Zane discovers a workshop that holds blueprints of himself, proving he's actually an android. Afterwards, he remembers he had a father: a man who built him to be the son he never had. Unfortunately, Zane outlived him, but his father switched off all of his memory right before collapsing on his deathbed so he would never feel the pain of loss. Zane sheds a single tear and re-activates his memory- and unlocks his True Potential.

- Light Is Good: White uniform, blond hair, and the nicest of the ninjas.

Lloyd Garmadon, the Green Ninja
The childish son of Lord Garmadon who believes he is destined to follow in his father's footsteps as a dark alchemist overlord. Kicked out of his Boarding School for Bad Boys, Lloyd is shown to be immature and has a dire love for candy, as well as a former grudge against the Ninja for humiliating him. Lloyd wreaked havoc on Ninjago by releasing the Hypnobrai, Fangpyre and Anacondrai tribes, however each took advantage of his naive behavior and betrayed him, leaving him to be defeated by the Ninja. However, Sensei Wu, his only uncle, took pity on him and convinced him to fight against the Serpentine, which he accepts. He later becomes the Green Ninja, meaning he is prophesied to defeat his father, Lord Garmadon.

- The Atoner: Shows genuine remorse for releasing the Serpentine after his Heel–Face Turn.
- Badass Adorable: Well, before the Rapid Aging that is, but it might still count.
- Big Bad Wannabe: In the first season. It didn't go so well as he learned all snake tribes couldn't be trusted. At one point, when Fangtom and Skales are discussing what to do with him, Fangtom suggests turning him into one of them, but Skales says "Nah, the little tyke's pretty useless."
- Bratty Half-Pint: Also pre Heel–Face Turn. Grows out of this in a second.
- The Chosen One
- Chrome Champion: His suit turns golden after becoming the Ultimate Spinjitzu Master.
- Daddy Had a Good Reason for Abandoning You: Lloyd was abandoned to protect him from the evil that consumed his dad. Season 4 hints as to how he harnessed that evil.
- Dark and Troubled Past: Abandoned by his parents (not that they had any other choice) and thrown into a boarding school for kid villains, heavily bullied at said boarding school for not having the drive to commit actual evil, and trying to prove his worth, only to fall into Humiliation Conga over and over again. Luckily he met his uncle and the ninjas and he got better.
- Demonic Possession: Morro pulls this on him for a huge number of episodes in Season 5.

Lloyd: Why do I always get tied up?
- Lampshaded in "Double Trouble."
- Again in Season 5 when Morro takes him over.

- Foreshadowing: He said he was kicked out of the Boarding School for Bad Boys because he didn't have the drive to commit any actual evil. Then he went and became the strongest hero in Ninjago. Go figure.
- Freudian Excuse: According to Word of God, he escaped from his school for bad boys, because he got fed up with the bullying he suffered there.
- Friendless Background: During his time at the Boarding School for Bad Boys. Brad was his Only Friend, though.
- Golden Super Mode: When he realizes his true power during his battle with the Overlord.
- Goo Goo Godlike: Being the Green Ninja he can use the all powers of the Golden Weapons, without touching them. He also used Spinjitzu on one his first tries. And he's only about 10. However, this is also somewhat problematic, as it means he can't control his true power just yet.
- He finally masters his powers in "The Rise of the Spinjitzu Master", becoming the Gold Ninja and destroying the Overlord.
- He Is All Grown Up: Due to his Heroic Sacrifice.]]
- He-Man Woman Hater: Implied a few times. Must be because he is young and he doesn't like girls yet.

- Knight of Cerebus: He's not technically a villain, but the series gets less funny and more dramatic once he grows up.
- Law of Chromatic Superiority: He rises above the others and becomes the Green Ninja.
- The Leader: Takes over Cole's role after he Took a Level in Badass as a result of a Plot-Relevant Age-Up in the last episodes of the second season. By the fifth season, it is even lampshaded by many characters, including Cole himself, that he is the leader of the ninja.
- Meaningful Name: The name Lloyd means grey in English tradition, which aptly describes his morality before growing up.
- Neck Lift: Happens in "Rise Of The Great Devourer". Okay, so technically he gets grabbed by the shirtfront, not his actual neck, but it still works.
- Overlord Jr.: He wore a cape, had an evil laugh, and sided with the most despicable creatures in Ninjago.
- Plot-Relevant Age-Up: He was left with no choice but to discard his childhood to save the child-ified Ninja from a monster.
- Happens again in "Wishmasters", when Lloyd wishes to be wise like Sensei Wu. Not only does he gain increased agility and intelligence, he also ''becomes like him'', aging him to an old person.
- Grows back to a teenager in "The Way Back", when Jay's wish erases everything that happened in the entirety of Season 6.
- Punny Name: Lloyd Garmadon, son of Lord Garmadon
- This confuses the Ninja in the first episode thinking that Lord Garmadon came back when it was only his son Lloyd.
- Rookie Red Ranger

- Stepford Smiler: Type A.

- Tagalong Kid: Post Heel–Face Turn, except he isn't really The Load. The kid part soon becomes subverted.

- Took a Level in Kindness: Post-Heel–Face Turn, he became more open towards his uncle and fellow ninja.
Nya, the Water Ninja/Samurai XSister of Kai and the former owner of Four Weapons, Nya was held captive by Samukai on Lord Garmadon's orders, seeing her as a potential pawn in his conquest for power. She was finally rescued by her brother at the Fire Temple and awaited his return from the Underworld. She eventually moved in at the Monastery with the four Ninja, where she trained to perhaps become a future Master of Spinjitzu. Headstrong and courageous, she is determined to prove she can become a ninja and prove her brother wrong, so she adopted the mysterious persona of Samurai X, a high-tech crime-fighting samurai clad in red armor and uses a large robot as a means of transportation. She also has a mutual crush on Jay.In Season 5, she manages to unlock her true potential as a ninja of water.
- A Day in the Limelight: Season 5 focuses a lot more on her than the other Ninja.

- Badass Normal: No powers, but she makes up for it in awesome skill, and gadget making.
- Badass Driver: Her performance with the drill car thing in "The Last Hope". Oh my God, yes.
- Big Damn Kiss: With Jay in "The Way Back".
- Brainwashed and Crazy: In episode 25 she's exposed to the Overlord's Psycho Serum. The results aren't pretty.
- Cool Car: We have never seen her use it personally, but the car that Lloyd and his dad borrow in episode 28 definitely qualifies.
- Fatal Flaw: Nya's greatest weakness is feeling weak. Since she's so good at so much, when she encounters something she can't instantly master she gives up without trying. She needed to learn to accept failure before she could unlock her true potential.
- The Chick: She manages to play this role without being officially apart of the Five-Man Band. It gets subverted once she becomes a part of them.
- Died in Your Arms Tonight: In "The Way Back", she ends up dying in Jay's arms, after the Ninja weaken Nadakhan with a Tiger Widow Venom dart, only for some of it to land on her. note Luckily, Jay's last wish ends up reversing everything that happened in Season 6, saving Nya.
- Everything's Better with Samurai: Her mecha-suit is shaped like a samurai.
- Gadgeteer Genius: Not only did she build her Samurai Mech and armor by herself in the spare time she had while the Ninja were on missions, she modifies the Ultra Sonic Raider to incorporate a detachable flight module, and later builds Kai his own Fire Mech.
- Gave Up Too Soon: As pointed out by Sensei Wu, Nya had a very rocky time trying to do any other mundane task in her life because she always couldn't stand failing once and forcing herself to do something else, only to repeat the cycle. This comes up really hard on her when she tries to become the Water Ninja.
- Generation Xerox: While her brother inherited their father's fire element, Nya inherited the water element from her mother.
- Giant Wall of Watery Doom: She's able to create one to defeat Preeminent once and for all.

Sensei Garmadon, formerly Lord GarmadonGarmadon is the brother of Sensei Wu and the elder son of the first Spinjitzu Master. As a child, he was infected with evil by the Great Devourer, and its influence grew on him throughout his life until he became a full-fledged villain, determined to conquer Ninjago. Before he succumbed fully to the evil in his blood, however, he fell in love with a woman called Misako and married her, at some point conceiving their son Lloyd. Garmadon was eventually banished to the Underworld as a mutated figure, and he assumed leadership of the Skeleton Army. He plotted to return to collect the Golden Weapons and reshape Ninjago in his own evil image. After facing the Ninja for the first time, Garmadon escaped and grew even more powerful, now further mutated with ‘’four’’ arms.The culmination of his villainy was to be 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. In penance for his evil, Garmadon set up shop as a sensei, trying to take a pacifist path and eventually failing during the Nindroid incident. Catching his son trying to sneak off to an underworld tournament with the Ninja, Garmadon joined them, knowing their host only too well as his former and very evil sensei, Master Chen. Garmadon did his level best to protect Lloyd during the tournament, including defeating an old rival once and for all, and finally made a Heroic Sacrifice to stop a second Serpentine War.
- Anti-Villain: Type I and II.
- The Atoner: From season 3 onwards.
- Badass Grandpa: As a Brought Down to Normal (apparently) middle-aged human. He may no longer be in his prime, but he can still kick butt and take names with the best of them.
- Badass Pacifist: Has sworn to never fight after pulling his Heel–Face Turn. This doesn’t stick past season 3.
- 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.
- Big Bad
- 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.
- Dark Is Evil: Though he isn't very happy with being evil.
- 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.

- 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.
- 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 aae on opposing sides.
- Good Parents: Never stops trying to be as good a father for Lloyd as he can be.
- Remains this post Heel–Face Turn.
- Grumpy Old Man: Towards the Ninja in season 3, and with good reason.
- Heel–Face 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.
- Heel–Face 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. Garmadon may still be alive, but he’s trapped in the Cursed Realm, currently with no way of getting back home.
- Late-Arrival Spoiler: He’s been one of the good guys for two seasons now.
- 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 two 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.
- 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.
- 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.
- The Power of Creation: The Mega Weapon he obtains at the beginning of season two 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, Garmadon 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.
- 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.
Dareth the Brown Ninja(?)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.
- 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 two 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.
- Small Name, Big Ego
- Speaks Fluent Animal: Manages to get two sharks to back off.

- Amazingly Embarrassing Parents
- 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
- 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.
Dr. JulienZane'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 a little longer, as he was still frail and weak.

SamukaiThe four-armed King of the Underworld. He was defeated by Lord Garmadon when he was banished to the Underworld, causing him to step down and allow Garmadon to control the legions of the Underworld. Samukai leads the Skulkin Army in the Surface World of Ninjago, carrying out Garmadon's orders and seeking the Golden Weapons of Spinjtizu. Soon, Samukai possessed the four weapons and betrayed Garmadon, only to be vaporized by the power of the weapons combined.

The Serpentine are snake-like creatures and act as the series antagonists.
HypnobraiThe Hypnobrai are a blue-colored faction of the Serpentine. As their name implies, they use hypnosis. They are the first tribe to be released.

- Monster Is a Mommy: Has a son in the time between the Overlord's defeat and his return in digital form.

- Mook Lieutenant: In the episodes where Garmadon controls the Destiny's Bounty.
SlithraaSnake of Ice and Warrior for the Hypnobrai Tribe. When Lloyd stumbled upon the Hypnobrai, Slithraa attempted to mind control him but ended up controlling himself, thus allowing Lloyd to take over the Hypnobrai tribe, much to the dismay of the others. He was formerly general of the tribe, before Skales took his place after defeating him in the Slither Pit.
- Brought Down to Normal: His fate after losing the Slither Pit duel with Skales.
- Dragon-in-Chief: To Lloyd when he had control of the Hypnobrai, as the only reason he had any authority among them was because Slithraa was the General. When Skales defeats him and takes his place as leader, Slithraa loses all authority over the Hypnobrai and Lloyd is banished.
- Hoist by His Own Petard: Lloyd gets him to obey when Slithraa tries to hypnotize him and it bounces off an ice wall, hypnotizing himself.Lloyd: No. I will control you from now on.
- Put on a Bus: After Skales takes his place as leader, Slithraa begins appearing less frequently. "The Snake King" is the last episode he appears in before disappearing entirely, and that was only a cameo appearance on (appropriately enough) the Snake Bus.

He plans to unite the five Serpentine tribes to find the four Silver Fang Blades and unleash the Great Devourer.

- One-Man Army: Defeated all the serpentine generals at once, and by himself.
- Proud Warrior Race Guy: He has a lot of respect for his species, and Chen's treatment of their memory pisses him off to the point that he willingly sides with the ninja.

The Great DevourerAccording to a legend, once all five Serpentine tribes unite, they will be able to find the four Silver Fang Blades and unleash the "Great Devourer". The Fang Blades are said to enhance the Devourer's abilities and make it unstoppable, releasing a terrible evil that will turn day into night. According to Sensei Wu, it will keep growing as long as it consumes. Garmadon was nice until he got bit by the Devourer as a child, turning him into the villain he is today.The Devourer slept under the Lost City of Ouroboros until Pythor put the Fang Blades into the statue of it and it rose out from underneath the city. It was destroyed by Lord Garmadon with the power of the Golden Weapons of Spinjitzu.
- Attack Its Weak Point: Has one on the top of its head. Garmadon kills it by diving off the top of a building with all four Golden Weapons and attacking this weak point.
- Eldritch Abomination
- Extreme Omnivore
- Hoist by His Own Petard: It bit Garmadon and turned him evil in the first place. It's ultimately Garmadon who destroys it.
- It gets better: if Lord Garmadon hadn't become evil, he never would have sought the power to wield all four golden weapons. The only way to kill the Devourer? Strike its weak spot with all four golden weapons at once.
- Make My Monster Grow: The more it eats the bigger it gets.
- Omnicidal Maniac: Its goal is basically to eat everything, even its Serpentine worshipers.
- Sealed Evil in a Can: Was sleeping under the lost city of Ouroboros until Pythor placed the Fang Blades back in their proper place, releasing it.
- Start of Darkness: Described in the fourth graphic novel:"Once, when the world of Ninjago was new, all things were bright and peaceful. Farmers toiled in their fields, in harmony with all the creatures of land, sea, and air. But in all things, there must be a balance. And so darkness crept upon the land, and came upon a lone snake in the grass."
The Overlord Army
The OverlordAn ancient evil from Ninjago's past that fought with the first Spinjitzu master in the past. He helps Lord Garmadon turn Ninjago into his own image, but later betrayed him and took over his body. His body is ultimately destroyed by Lloyd in the Final Battle with him, but he now lives on as an evil AI.
- A.I. Is a Crapshoot: Is this in the new season.
- As Long as There Is Evil: During the final battle, he gives a speech, saying 'as long as there is light, there must always be shadow,' implying he's this trope. Considering having a massive explosion go off INSIDE HIM and destroy his physical form wasn't enough to kill him (though it probably would've put him out of commission for a good while had Cyrus not accidentally resurrected him), he probably has a point.
- Big "NO!": Gives a series of them upon realizing Lloyd is about to destroy him.
- Clipped Wing Angel: When the ninja botch his attempt to regain his physical form by siphoning Lloyd's golden power, he returns in the form of a purple blob. Once he's stable enough, however...
- The Corrupter: His dark matter has the ability to turn whatever it touches evil. He also makes Garmadon worse and worse through his manipulations. He's also the being responsible for creating the Great Devourer and thus turning Garmadon evil in the first place.
- Devour the Dragon: The Overlord eventually betrays Lord Garmadon and possesses his body.
- Eldritch Abomination: Has many qualities of one.
- Eviler Than Thou: To Lord Garmadon.
- Evil Sounds Deep: After taking over Garmadon's body.
- Knight of Cerebus: Is about the only villain in the entire series (at least the only one with a mind of its own) with absolutely no comical traits at all, and the leader of an army of Nigh Invulnerable soldiers at his command.
- Idiot Ball: Usually a relatively adept manipulator, he sometimes fails to see the easier option when caught up in his own schemes. He insists on reclaiming his original body. As his computerized state potentially grants him whatever body or even bodies he wants, this is probably a case of this trope.
- Of course, since he requires electricity to function in his digital state, and the ninja have the Technoblades, which are capable of stopping, and perhaps even destroying, him while he remains in the system, he may have a valid point for regaining corporeal form. He also wants to skip finding a host that can fight from the inside this time.
- The process would also have the benefit of making him even more powerful.
- Light Is Not Good: His Golden Master incarnation, both times.
- Literally Shattered Lives: Zane defeats him the second time by absorbing his power and freezing him until this happens.
- Manipulative Bastard: Manipulated Garmadon into think he was the Big Bad, so he'd complete his ultimate weapon and disrupt the balance between good and evil, freeing the Overlord from his prison.
- One-Winged Angel: After taking over Garmadon's body, he takes the form of a gigantic black dragon.
- When the Ninja confront him in the digital world, he becomes a giant vaguely humanoid...thing made of darkness with numerous tentacles.
- Once he returns to full power as the Golden Master, his power takes on the level that he had in the digital world... in reality.
- Our Dragons Are Different: His true form is a giant black dragon.
- Pyrrhic Victory: He manages to escape the digital realm, but is unable to drain all of Lloyd's power and can barely keep his new body together.
- Satan: Pretty much the Ninjago version anyway. Is it any wonder he turns into a dragon for the final battle?
- Sealed Evil in a Can: The Overlord and the evil side of Ninjago which he inhabited were supposed to remain disappeared for as long as the balance between good and evil remained in check. However, Lord Garmadon's ambition to remake Ninjago in his image upsets that balance.
- Due to losing his body in the final battle with Lloyd, his soul is stuck in machines, and while that gives him a lot of stuff to control he still wants a new body instead of being stuck in a computer. He eventually gets it.
- This Cannot Be!:
- Is left in disbelief when Lloyd begins to fight back against him, unable to believe a mere human could manage to match him.
- Happens again when Zane pulls off his Heroic Sacrifice, absorbing the Golden Master power to ultimately defeat him.
- Ultimate Evil: Spends most of his screen time a disembodied voice considered to be the most evil entity in the entire series. When he finally appears in person, he's as frightening and powerful as he was made out to be. Both times.
- Worf Had the Flu: The only reason Lloyd managed to stand any chance at all in their first fight was because Garmadon was Fighting from the Inside, and even then, the Overlord beat him and left him with an injured leg. Even after Lloyd obtains his Golden Super Mode, the Overlord is able to fight him fairly evenly.

- Sealed Evil in a Can: Were sealed underground with the defeat of the Overlord, but unleashed by the Serpentine accidentally unearthing them.

- Reptiles Are Abhorrent: He and his men have a snake motif or, more specifically, an Anacondrai motif. Which is fitting as he sided with the Serpentine during the war against them.

- Evil Sorcerer: Has shown the ability to cast spells.
