Characters: Samurai Jack
open/close all folders
Voiced by: Phil LaMarr, Jonathan Osser (Young, Jack in Egypt episode), Keith Ferguson (Punch Time Explosion)
Our hero, a samurai and the son of the samurai who initially released (and then defeated) Aku. He trained in every country in the world in preparation for the final battle... only to be hurled into the future before he could land the killing blow. Now he must Walk the Earth, seeking a way back to the past to finish that battle... not that this will stop him from setting things right in the future as well.
- 100% Adoration Rating: Aside from Aku and his minions, Jack's deeds has made him beloved by everyone, and he is now seen as a beacon of hope under Aku's tyranny. He is even revered in outer space, by the Tech Astronauts he helped escape Earth, and the prince and princess of an alien world who were stranded and held captive by Aku, preventing them from saving their homeworld with reinforcements. The latter even builds a statue of Jack on their world after their mission succeeds.
- Appropriated Appellation: Calls himself Jack after some street kids refer to him as such. (They said it in a way to mean "pal" or "dude", but he didn't know that.) His real name was never given in the series.
- Aloof Ally: Jack is one to most of the characters, including the Canine Archaeologists, The Woolies and even The Scotsman, despite him being his best friend.
- Back-to-Back Badasses: He and The Scotsman ever since the first time the two started working together.
- Badass: One man, lost in time, declares war on the invincible, immortal ruler of the Earth. And in nearly every episode, he claws his way closer to victory.
- Badass Back: Just trying to attack him from the back would get you sworded in half.
- Badass Boast: "I am the lost son of the land you have pillaged. I am here to reclaim it."
- Badass Long Robe: He is a samurai.
- Badass Normal: Jack has fought all kinds of high-tech or supernatural villains with nothing but his skills and his divinely-forged blade.
- Badass Pacifist: Jack would bow down for you to avoid a fight, but don't push him into one. If he sees no other way out, he might as well just kick your ass.
- Bash Brothers: With The Scotsman.
- Because Destiny Says So: It's heavily implied that he will be able to go back to the past....eventually. But for some reason the Powers That Be have decreed it will be a very long time before that actually happens.
- Berserk Button: Put simply, evil sets him off.
- Beware the Nice Ones: HOLY SHIT SHOULD YOU EVER!!! He puts the comfort and life of any innocent being he meets before his own, but getting on his bad side is a death sentence.
- Blood-Splattered Warrior: Well, it's oil instead of blood, but Jack regardless blatantly and commonly gets the same concept applied to him in his battles with a color change to be PG.
- Celibate Hero: He's got at least four valid motives for avoiding romance; it would distract him from his quest, he's a danger magnet, he'd have to return to the past, and he's been burned before. That doesn't stop the fangirls, though.
- The Chosen One: Revealed to the viewers, but not known to Jack.
- Charles Atlas Superpower: He does many astounding, even 'impossible' things, all as a result of his training.
- Chronic Hero Syndrome: He might be able to get home faster if he ignored the suffering of those around him. Shoot, because this future might cease to be if he succeeds, no one would ever know. But, if he were able to ignore the suffering of those around him, he just wouldn't be Jack.
- Clothing Damage: Seems to be a magnet for it after season one.
- The Comically Serious: He does have a sense of humor and gets some witty one-liners, but these moments are few and far between.
- Compressed Hair: Don't be fooled by that tiny ponytail. Once that pin's gone, you get some long, flowing locks that couldn't possibly make up that tiny ponytail.
- Consummate Liar: He frowns on deception, but he can be a pretty good liar when he needs to be.
- Determinator: Aku will fall. No matter how many obstacles are in Jack's path, no matter how many enemies attempt to destroy him, no matter how many times he fails.
- Department of Redundancy Department: Only this one moment in Jack vs Aku.
- —>Jack: "I knew, that you knew, that i knew, that you knew that i knew you would cheat'"''.
- The Drifter: He doesn't stay in one place for long in his never-ending quest to return to the past.
- Evil Knockoff: Mad Jack, a being that was created from Jack's negative emotions.
- Empowered Badass Normal: When wielding his sword, as it is the only thing that can harm Aku.
- Also, during the rematch against the Ultra-Robots. Their adamantium chassis meant that Jack's raw strength wasn't enough to cut them, even with the superior power of his sword. This problem was resolved when the robots' creator, Extor, granted Jack a power gauntlet which increased his physical strength enough to where he could slice through the robots. It broke before he could defeat the last one (a sword wielder), forcing Jack to call on the gods of righteousness to aid him.
- Fish Out of Temporal Water: A resident of the distant past trapped in the distant future. He's managed to adapt pretty well, all things considered.
- Foregone Conclusion: The ending of the episode "Jack and the Traveling Creatures" reveals that, while it will be at least a few years before then, Jack will eventually return to his own time.
- Future Badass: Shown briefly by the Guardian's time portal.
- Good Is Not Soft: A sworn protector of the innocents and the biggest threat to all evil villains.
- Good Is Not Dumb: While he's not being hindered by Chronic Hero Syndrome, he's shown he can be very clever.
- Hat Damage: Whenever he wears one, it's usually the first thing to go.
- The Hero: He was designed to be a very simple example of the classic hero.
- Honor Before Reason: Which makes sense, since honor pretty much defines what a samurai is all about.
- Humble Hero: He is generally soft-spoken and will often apologize to those who have offended him, in hopes of averting violence. (This is an action series, so you can guess how well it works.)
- Idiot Ball: Not often but sometimes he doesn't recognize some Aku's disguises (no watter what Aku always maintains his coloring) until it's too late. But then again, he's in a future where anything can happen.
- In a Single Bound: An episode has Jack going through Training from Hell to massively boost his leg strength and match the incredible jumping skills of a tribe of monkeys. Jack also provides the quote from that episode for this trope.
- Incorruptible Pure Pureness: Not Jack himself: one terrifying incident had him fighting The Corruption in his own body, and it was a mighty struggle. Jack's sword, however, fits the trope more closely: it can't even scratch the innocent or righteous.
- Implausible Fencing Powers: Being able slice through anything comes from the sword's magic, but he also blocks gunfire on a routine basis, even at close range.
- Katanas Are Just Better: Not as a rule (enemies' katanas don't get any special treatment.) Jack's particular sword has a divine heritage and considerable backstory, though. Two other magic swords, a broadsword and what can best be described as a BFS, appear in the series, but Aku doesn't seem terribly worried about them. One belongs to The Scotsman and is an example of Like Cannot Cut Like, the other was created by a race of Yeti in the hopes of defeating Jack. They fail.
- Knight Errant: He wanders the land, dispensing justice and hope.
- Lantern Jaw of Justice: The jaw's half the length of his face, and the man it's attached to is decisively just indeed.
- Light Is Good: Besides wearing all white and being contrasted against dark enemies, he apparently also knows a very specialized form of ninjitsu that allows him to blend in with the light.
- Limited Wardrobe: Always appear to be wearing the same white kimono - it's even unlimited in its limited-ness, because he keeps suffering Clothing Damage!
- Any money he acquires in his journeys is probably spent on replacement kimonos.
- Made of Iron: A variant. It doesn't matter how intense the battle is. He always comes out of it alive, and without permanent damage - but he takes a lot of flesh wounds.
- Martial Pacifist: He doesn't actually like fighting. It is a tool he would prefer to reserve for Aku and other agents of evil.Jack (to the crowd at the Dome of Doom): I will no longer do battle for your amusement. You will have to get your entertainment elsewhere!
- Master of All: If it's a type of weapon that existed in his time, he can pick it up and use it expertly. The same goes for when he only has his bare hands. He was also taught a number of other skills, such as sailing, hunting, and horse-riding, and is very good at all of them. The one exception appears to be firearms, as they were not invented during his training, and he is never seen using one.
- Master Swordsman: While Jack is talented at many things, nothing compares to his swordsmanship, with which he can slice through bullets with ease.
- Moses in the Bullrushes: As soon as Aku attacked their kingdom, his parents sent him out of the country on a twenty-year journey to master every form of combat on (the known parts of) Earth.
- Mr. Fanservice: Oh so much. He's even got some fangirls in-universe!
- Named by Democracy: It's what the first people he talks to call him and they introduce him as Jack to their friends... then Jack is put up on his wanted posters...
- Nice Guy: Very much so. He does have a temper, but you have to work hard to set it off. Ordinarily he is humble, polite, kindly generous, and helps with no expectation of reward.
- Nice Hat: Sometimes wears one made of straw. Episode 26 reveals that he knows how to hand-weave a hat from the husks of straw, which explains how he always manages to procure replacement hats when they get continually pulverized.
- The pilot had him wearing a kabuto helmet made from scrap metal as part of a set of improvised armor.
- No Name Given: "Jack" is an alias he took in the future.
- Odd Friendship: The Scotsman is pretty much the only person he could call a friend. They're about as different as they come.
- One-Man Army: In the premier he takes down a whole army of killer robots by himself and wins, and in other episodes he routinely destroys multiple opponents at once.
- Only Known by Their Nickname: Jack's real name is never mentioned in the series, not even by his parents! When Jack tells Ikra (who, as Aku, is almost the only being in the future that could know Jack's name) that he is called Jack, her expression is priceless. Of course, had she accidentally let slip his real name, she would have blown her cover right then and there.
- The Quiet One: Usually speaks only a few lines each episode; there are even a couple in which he appears, but has no dialogue at all.
- Red Oni, Blue Oni: The blue to the Scotman's red.
- Samurai: No kidding!
- Samurai Ponytail: Jack fits pretty clearly into the first variation of the trope with his noble attitude.
- Set Right What Once Went Wrong: His primary goal is to find a way back to his own time so he can destroy Aku before the Bad Future comes to pass.
- Shirtless Scene: Not so much during the first season, increasingly as the show goes on, almost qualifies as a Walking Shirtless Scene at some points.
- Significant Birth Date: As shown in "The Birth of Evil," he was born the very same day that his father originally defeated Aku.
- Slipknot Ponytail: Also a magnet for this after season one (not as much as the Clothing Damage example, but it does happen).
- The Stoic: Most of the time...
- Strong as They Need to Be: He can consistently fight armies of enemies, but his limit varies depending on what the plot requires, along what his sword can cut through. It can hurt Aku, when almost nothing else can, and bring down giant robots, but it can almost never cut through the weapon his enemy uses.
- Suddenly Always Knew That: He occasionally displays skills that he hasn't used before, like blind-fighting to battle the Three Blind Archers, using sunlight to conceal himself to fight the Ninja, and so forth. Such untapped skills are generally easy to justify (see Tyke Bomb.)
- Throwing Your Sword Always Works: It's come up in a couple of desperate situations.
- Tyke Bomb: Non-evil example; Jack began training with numerous combat styles and many different warriors as a child, after he and his mother fled Aku's second attack on their homeland. Unlike most other examples, he was still brought up as a benevolent samurai with a code of ethics.
- Flashbacks scattered thorough the series' run show that despite the rigorous training, Jack made many friends in the different countries he visited, played, and learned with the different people and cultures he met. Some people should take notes from this series on how to properly raise a One-Man Army.
- Warrior Prince: The son of an Emperor, and trained in the arts of war.
- The Wise Prince: He's actually a prince, and the day Aku appeared signaled the end of his sheltered childhood.
Eldritch Abomination fell to Earth, wiping out the large saurian creatures that dominated the planet at that time. It existed as a mindless evil for millions of years until a brave king attempted to destroy it: the attempt to destroy it instead gave it consciousness. It became Aku, a being of pure darkness and evil. When the samurai who would later be called Jack came to fight him, Aku hurled him into the future as a last-ditch effort to survive. In the future, Aku rules the world, and devotes a lot of effort to finishing Jack once and for all.
- Achilles' Heel: Jack's sword. Also, he can be hurt by other powerful deities such as the Water Goddess.
- The Ageless: Immortal. That's pretty straightforward.
- Attack of the 50-Foot Whatever: And he is only a fragment of what he came from.
- Badass: Not only did he manage to actually rule the world, but has also killed many, many strong and armed warriors in his history of ruling, and while he may not be as skilled or balanced as Jack, he's still a pretty good fighter, and more brutal and ruthless.
- Badass Beard / Beard of Evil: That's a pretty stylish goatee of flame.
- Badass Boast: Who dares to summon the Master of Masters, the Deliverer of Darkness, the Shogun of Sorrow, Akuuuuu?
- Badass Baritone: Mako does a good job on his humorous yet diabolical and sinister voice with an Evil Laugh in most of his appearances.
- Bad Boss: You're probably safer as one of his victims than one of his minions.
- Been There, Shaped History: He, or rather his original mindless form, was the comet that wiped out the dinosaurs.
- Beware the Silly Ones: Aku is actually pretty lovable... and utterly evil.
- Big Bad: In the intervening time between Jack's time travel, Aku has come to dominate not just Earth, but countless other planets, tyrannizing countless across space and time.
- Big Brother Is Watching: He possess a screen that allows him to constantly watch Jack wherever he is. It was only interrupted when Jack entered a particularly holy place - resulting in old-fashioned TV static.
- Breath Weapon: Can breathe fire in both his normal form and whenever he turns into a dragon.
- But for Me, It Was Tuesday: Inverted, a group of aquatic aliens whose planet can't sustain them anymore due to their world's oceans disappearing come begging him for help. He does remember them, he just chooses not to help - since he's the one who stole their oceans.
- Card-Carrying Villain: Often refers to himself by several evil-sounding titles such as "Shapeshifting master of darkness", just in case you couldn't tell he was evil by looking at him.
- Chronic Backstabbing Disorder: See Stupid Evil. He nearly always betrays anybody he works with, as soon as they fail the mission, even though he never stands to gain anything from it.
- Combat Tentacles: Whenever he's in octopus form (one of his favorites) or reverts to formlessness.
- The Comically Serious: He's always funnier when he's trying to be serious. As Genndy Tartakovsky stated, he's meant to have a serious personality but humorous at the same time.
- Complete Immortality: He hasn't aged at all since the day he was 'born' and heals from injuries almost instantly. The only weapon that causes him real harm and could potentially kill him is Jack's sword. He can be held at bay by a few other entities (notably the water goddess from the backstory of 'Jack and the Gangsters', and the Ancient Master from 'Jack and the Monks'), but not injured. At all.
- The Corruption/The Virus: Aku is a living mass of evil that is capable of infecting anything or anyone, gradually turning them into a small Aku clone. The main impetus of the aptly titled episode "The Aku Infection" has Aku suffering from a cold and sneezing on Jack, gradually turning him evil.
- A Day in the Limelight: "Aku Tales", which focuses on his attempts to win over a group of children. Jack only appears in his stories.
- Dark Is Evil: In addition to being mostly black, his primal form is nothing but a billowing dark mass.
- Deadpan Snarker: Depending on his mood.
- Determinator Considering the many times that Aku has failed at defeating Jack, Aku will stop at nothing to get him destroyed.
- Diabolical Mastermind: Very cunning and decieving.
- Dirty Coward: Since Jack's sword is the only weapon that can truly hurt him, Aku largely avoids direct confrontation with him, only doing so when he has some kind of advantage. And when he loses that advantage, you can guarantee that he'll pull a Villain Exit Stage Left.
- Ditzy Genius: While Aku can be smart and cunning, his plans are not always the most well-thought ones.
- Do Not Go Gentle: His usual response to a serious setback is to run away. But if that's not an option, he'll fight ferociously with every resource he's got.
- The Dreaded: He's called Aku for a reason.
- Dystopia Justifies the Means: Subverted. The entire world could be reduced to uniform misery and despair, but he'd rather it present some occasional beauty, hope, and peace... so that he can crush it like a bug.
- Eldritch Abomination: Spawned from the remains of a much larger one.
- Even Evil Has Standards: Aku may be a being of unspeakable evil, but children are free to contradict and question him as they will.
- He also had a standard in The Aku Infection, where he didn't want to fight Jack because he got cold out in the snow.
- Evil Cannot Comprehend Good: A large reason that his attempt to throw Jack into the future backfired. He'd expected a world ruled by him would allow him to crush Jack effortlessly when he arrived. He never took into account that a hero arriving and successfully fighting back his forces would trigger Hope Springs Eternal and start giving the oppressed masses someone to rally behind. Also shows when he tries to make himself out as the good guy in the stories he tells to children in one episode and one of the prime reasons it doesn't work is he didn't really comprehend what being The Hero actually meant — the closest he can come to understanding heroism was free beef jerky for all! This wasn't for any altruistic reason, it was because the idea of being loved pleased his ego.
- Evil Genius: Zig-zagged: Aku always has a strategy for his evil plans, but he fails pretty regularly. He has, though, planned some very intelligent and cunning schemes, such as transforming into a woman who saves Jack's life to trick him into the portal he's trying to reach, only to break it. And since he already has succeeding in ruling the world, it is to know that he isn't a ditz.
- Evil Gloating: What's the point of hurting people if you don't get to revel in their expressions of horror, despair and hatred?
- Evil Is Hammy: The way he talks is so bombastic and over the top!
- Evil Is Petty: Despite having higher goals and ambitions, Aku cannot resist committing unnecessarily cruel and petty things to people he's already screwed over, often to prove he can or just for a sick kick at their expense. He ends up taking it to Stupid Evil levels as he always backstabs anyone he makes a deal with, just to laugh at their misfortune.
- Evil Laugh: Sincere, sinister, and usually preceded by something terrible happening to someone.
- Evil Overlord: Currently rules the whole planet and expanding his empire beyond.
- Evil Plan: Conquering the Earth was a done deal before the pilot ended. The one that drives the plot is his attempts to kill Jack, and, failing that, prevent him from traveling back in time.
- Evil Sounds Deep: As his voice actor once said, "Evil comes from the belly."
- Evil Sounds Raspy: He has a raspy voice which matches his evil laugh.
- Eye Beams: Multiple types for multiple purposes; force blasts, incendiary force blasts, alchemy, summoning, teleportation, transformation, necromancy, and general spellcasting. Basically, whenever Aku's feeling lazy, he'll just use his eyes.
- Fangs Are Evil: His have the distinct Oriental pattern in which the canines curve outward.
- Faux Affably Evil: Aku is comedic and likable on the surface and is certainly capable of having nice, civil conversations with people, but he's a monstrous brute who loves to bring misery and suffering to everyone in reach. He would probably be the most disturbing villain in animation history if he wasn't so damn entertaining to watch.
- Foil: He's very much the exact opposite of Jack. While Jack seeks to do good wherever possible, even at risk to his well being and goal of returning to the past, Aku always seeks out any action where he make life miserable for others - even if it would be to his disadvantage in the long run.
- For the Evulz: The only real explanation for his actions: Aku does what he does because the suffering of others amuses him, as demonstrated by his signature Evil Laugh.
- Four-Fingered Hands: Considering he's thoroughly evil, there's probably a meaning to it.
- Galactic Conqueror: Ruling the Earth wasn't enough, so he extended his dominion to other planets. It's not clear whether he's conquering them or just laying waste to them, but he's garnered enough attention to attract aliens (usually traitors, criminals, and bounty hunters) of all sorts to the Earth.
- Holy Burns Evil: Jack's divinely-forged sword causes him horrible pain with even the slightest cuts.
- Jerkass: Though he usually acts in a very civil, polite, cordial, sophisticated and tends to swing back and forth between a comedic villain and truly evil one. Notable acts of evil include in the pilot episode when some aliens that lived an aquatic world whose oceans were dried up come to him requesting to live on Earth and he reveals that he stole their oceans. On another occasion, he forces a scientist to build a set of indestructible robots to kill Jack under the promise of sparing his village if does, and then tests the robots out by having them burn his village to the ground and kill everything in it.
- Hero Killer: In Birth Of Evil, he destroyed multiple of the warriors working for Jack's Father. It is also most likely possible that Jack's Father died of being enslaved by Aku in an old age without water, in the future.
- Kick the Dog: Really likes doing this. Outside of his need to back-stab everyone, he also once imprisoned a Viking king in crystal and forced him to watch as he destroyed his kingdom, after which the grieving sole survivor was made immortal and sealed in the heart of a mountain. On another occasion he disguised himself just to accompany Jack on a quest, find a magical artifact Jack could use to return home, and destroy it at the last instant so he could mock Jack.
- Large and In Charge: Rules the world and has a Shapeshifter Default Form that is usually several stories high at the least.
- Large Ham: So hammy that one of the first things he makes his slaves do is build statues of him.
- Laughably Evil: He's rather... goofy for being the Ultimate Evil and all. Varies depending on the episode, there are some that present him as legitimately evil and threatening figure. Or sometimes a bit of both.
- Like a Badass out of Hell: The first thing he did when he came back to life in the premier was to attack the town, and Take Over the World.
- Likable Villain: He's a pretty fun guy, whenever he isn't performing any genocide and slavery and treachery.
- Made of Evil: Aku's substance is flexible, strong, pitch-black, capable of re-sealing after most injuries, and has an extremely horrible effect when taken internally. It's Evil.
- Make Me Wanna Shout: Aku can use loud screams powerful enough to damage the landscape as a form of attack.
- Meaningful Name: The word "aku" means "evil" in Japanese. It's also worth noting that he's the only major character in the series who goes by his (original) name.
- Morphic Resonance: He always has the same black, red and green color-scheme in every form he takes.
- Names to Run Away From Really Fast: His namely is literally "evil" in Japanese.
- Narcissist: He once said "No mortal can defeat me" right before getting his ass handed to him, asked for a group of fish people to build statues of him every month, and sees Jack as foolish for even trying to fight him.
- Nigh Invulnerable: Demonstrated when we see stuff outside of Jack attack him. It doesn't seem to matter if it's ancient weapons or advanced technology, mundane forms of attack can't hurt him.
- Obviously Evil: Right down to his name!
- One-Man Army: He is able to take out many warriors at once.
- Orcus on His Throne: Justified. The entire premise of the show started because Jack could defeat him, so Aku actively avoids facing him himself unless he's gained some advantage that he's sure will let him win. "Tales of X9" also revealed that the entire reason he relies on an army for conquests is because he found taking over the world on his own was going at too slow a pace for him.
- Paper-Thin Disguise: Due to Morphic Resonance, it is often easy for the audience to tell that someone is just Aku in disguise. Jack is sometimes taken in; sometimes not.
- Playing with Fire: Can toss blue fireballs at opponents.
- Really 700 Years Old: He doesn't seem to have been conscious in a human sense until the Emperor attempted to destroy his prior form, the evil pool. By the time Jack returns to the timestream, however, Aku is many centuries old.
- Satan: He's definitely based on the devil. Hes' a demon overlord, who in the future turned the world into a post-apocalypse, and lives in hell (The Pit of Hate).
- Schmuck Bait: Aku distributed lots of "magic" around the world - time portals, wishing wells, secret magical or technological weapons. They're always Schmuck Bait.
- Sealed Evil in a Can / Sealed Badass in a Can: Jack's father defeated him by sealing him away instead of killing him. The first episode shows him breaking free and taking his revenge.
- Shapeshifter Default Form: Due to his origin it's hard to say if he's Type A or Type B.
- Sizeshifter: A natural extension of his shape-shifting ability, and in his default form he's usually gigantic. He tends to shrink whenever Jack's sword hits him, though.
- Slasher Smile: Right as he is about to stab Jack with his own sword in "Jack and The Zombies", he sports a sadistic smile with crazy eyes.
- Spikes of Villainy: His head is covered in branch-like horns and whatever form he takes tends to have a spike on each joint.
- Stupid Evil: He abuses Mooks, cheats those who strike bargains with him, or just spends too much time gleefully torturing Jack when he could easily crush him in an instant. Jack's very existence is owed to this happening time and time again.
- Super Strength: Even if he scales down to human size for some reason, he has superhuman strength. This seems to diminish, though, if he scales down into several human-like forms.
- Take Over the World: He already has, but apparently it's not enough.
- Third-Person Person: When he's being especially hammy.
- Unskilled, but Strong: Played with. Aku has shown on occasion that he is more skilled than he lets on as he is seen using weapons on occasion and is a surprisingly strong hand-to-hand combatant, but he relies mostly on his shapeshifting, his vast magic, and the fact few things can actually hurt him. One of those is Jack's sword.
- This is most shown and somewhat deconstructed in the aptly titled episode, "Jack Versus Aku". Aku challenges Jack to a final battle with only two rules: Jack is forbidden to use his sword and Aku is forbidden to use his powers. Though Aku manages to hold his own with just his Super Strength and hand-to-hand skills, Jack proves to be the better fighter and has Aku on the ropes, forcing him to break the rules to turn the tide.
- Unusual Eyebrows: "GREAT FLAMING EYEBROWS!"
- Villainous Breakdown: A gradual and humorous one in the episode "Aku Tales". When Aku attempts to win over children from their Hero Worship of Jack by telling them fairy tales painting him as the hero, one of the kids requests a story about Jack. Aku gets angry, but quickly acquiesces, attempting to paint Jack as the villain. As the episode wears on, the children begin to poke holes in Aku's stories, frustrating him and forcing him to change up his stories until they become increasingly convoluted. Eventually, Aku hits his breaking point and teleports back to his lair, greatly annoyed.
- Villainous Harlequin: His perpetual hammy attitude, clownish monster-face and general air of having fun suggest this trope. Though it is, in some ways, a facade.
- Villains Out Shopping: Is sometimes seen just hanging around his base when not attacking Jack, particularly in comedic episodes.Aku (on the phone): I think I'm in the computer... Oh! Yes, Extra thick. (Evil Laugh) Yes! Thirty minutes or it's free!
- Voluntary Shapeshifting: He can transform into pretty much anything, usually an animal but he can also change his shape to the point where he's outright formless, and even introduces himself as a "shape-shifting master of darkness" during the opening narration.
- Weaksauce Weakness: As mentioned above, despite being an ageless, powerful, and immortal demon, Aku is vulnerable to viral diseases.
- Wouldn't Hurt a Child: Aku plays with this trope. In the beginning episode, a group of aquatic aliens comes to him seeking shelter on Earth due to having their oceans stolen. Aku admits that he was the culprit, causing the alien leader's son to call him a monster. Aku promptly vaporizes him with his Eye Beams, but consoles the grieving father by telling him that the boy was transported to the Pit of Hate. In a later episode, he attempts to win over a group of children by telling them fairy tales. And despite being more than capable and having every reason to harm them for their Hero Worship of Jack, he never does. Particularly when one child has the nerve to ask for a story about Jack. Aku gets mad, but acquiesces (though he does try to paint Jack as the bad guy). It seems that for all his evil, Aku draws the line at hurting kids.
- You Have Failed Me: His response to Demongo's defeat.
- Your Size May Vary: Possibly justified as given his shapeshifting, but even then his sizes varies from shot to shot. Most of the time, he's 5 times the size of a skyscraper, others he's only a few stories tall.
Voiced by: Jennifer MartinOne of Aku's aliases, just one of several forms which Aku assumed in order to travel closely with Jack while on a desert quest to find a jewel.
- Badass: Introduced herself by saving Jack.
- Big Damn Heroes: When she saved Jack.
- Foreshadowing: There are many instances in that episode of Ikra's true identity. When the shaman senses the 'ultimate evil', his last line said to Jack, "You don't understand!" After Jack and Ikra escape from Aku's robots, the robots simply stop their chase and close their eyes with satisfaction, awaring of a trickery. Then, a mouse feeds food from Jack, the mouse is scared of Ikra and digs itself to run away. There is a height difference that Ikra is slightly taller than Jack. When the jewel tests Jack and Ikra's hearts, it found out that Ikra is pure evil. The guardian mainly tries to fire its blast to Ikra (besides Jack not wanting to fight). Near the end, Ikra can fly and becoming a giant to defeat the jewel guardian.
- Obviously Evil: Her color scheme: black, green, and red orange should've been a dead give away.
Voiced by: MakoAnother one of Aku's aliases where he wants Jack to find the Gems of Cronus so that he can revive the Titan.
The Black MassOnly appearing in 'Birth of Evil', it is the source of all evil. Before it can consume the universe, three deities (Odin, Ra, and Vishnu) arrive to exterminate this great evil. Before it was completely destroyed, a fragment of it escaped and crashed forcefully on Earth in 65,000,000 BC. This is the original incarnation of Aku.
- Dark Is Evil: The true embodiment of evil indeed.
- Eldritch Abomination: It is a gigantic, formless mass.
- Greater Scope Villain: Of the whole series. It gave birth to Aku but it's not involved in the main story.
- Monster Progenitor: Since Aku can shape-shift, this mass at one point becomes a fully black armed creature while fighting the deities.
- Posthumous Character: It was already destroyed by the deities, but is reincarnated as Aku.
- Ultimate Evil: It has no form.
- Walking Spoiler: For what Aku originates.
Voiced by: John DiMaggioA large, extremely loud Scottish man, with a sword inscribed with magic runes and a machine-gun false leg. He's about as burly a warrior as you'll find, and one of the few creatures able to match Jack for combat prowess. Their initial meeting (based on the tale of Robin Hood and Little John's first encounter) resulted in a fight that went on for fifty hours and still didn't have a clear victor.
- Anti-Hero: Quite a bit more unscrupulous than Jack, though he's still a good guy.
- Back-to-Back Badasses: He and Jack do it every time they fight together.
- Badass: He fulfills the role in a much more fun-loving, almost maniacal way than Jack.
- Badass Mustache: A contrast with the clean-faced Jack.
- Barbarian Hero: He usually solves things with violence. However, that doesn't stop him from helping a friend in need.
- Bag of Holding: His sporran (the pouch on his kilt) can hold all sorts of things. Bagpipes. Grenades. Enormous gold nuggets.
- Bald of Awesome: Bald except his ponytail, which also marks him as a Fiery Redhead.
- Berserk Button: Do not screw with his bagpipes. He might turn your head into a flour sifter.
- The Big Guy: The enormous guy.
- BFS: A claymore inlaid magic runes. He's rather proud of how big it is.
- Blood Knight: Unlike Jack, this guy adores violence. At one point he apologizes to Jack for 'spoiling his fun' by using a grenade to shorten a fight.
- Boisterous Bruiser: Contrasting with Jack yet again.
- Brave Scot: He fears nothing. Well, except the Celtic Master of the Hunt. And his own wife when she's angry.
- Breakout Character: His popularity, along with being one of the only people capable of matching Jack, brought him back for three encore episodes.
- British Teeth: Discolored, different lengths, with gaps.
- Carpet of Virility: His head is about the only body part not covered in hair.
- Cool Sword: A BFS with magical runes that grant it powers similar to Jack's.
- Crouching Moron, Hidden Badass: Initially comes off as a comical blowhard who will quickly topple after foolishly challenging Jack to a fight. He then proceeds to match Jack blow for blow, reveals himself to have a magic sword that is equally as powerful as Jack's, and holds his ground for three days.
- Curb-Stomp Battle: When his opponent isn't Jack, the fight is guaranteed to end quickly.
- Defeat Means Friendship: He goes from an antagonistic bully to Jack's most trusted ally after an arduous fight.
- Determinator: Played for laughs. Unlike Jack, who eludes injury, he just suffers the Amusing Injuries and laughs at them.
- Dreadful Musician: He's terrible at playing the bagpipes, just don't tell him that to his face.
- Everything's Louder With Bagpipes: His Establishing Character Moment.The Scotsman: I see by the look on ye face that ye're likin' the sound of me pipes!
- Fire-Forged Friends: With Jack, whom he refers to as a brother.
- Flowery Insult: Gives one to Jack in their first encounter.
- Future Badass: Shown to be one in the final issue of the comic alongside the titular Future Badass.
- Good Is Not Nice: In his case, it's downright rude.
- Good Is Not Soft: The Scotsman is a good friend, but he's not afraid to use his sword and machine gun leg to protect the people he cares about.
- Henpecked Husband: Hilariously enough, he is completely under the thumb of his wife, who is actually both bigger and stronger than he is and whom he dotes on endlessly. That said, the two have a happy marriage.
- Happily Married: Inexplicable, but true! This is probably the reason why he wasn't affected by the Sirens' song.
- Hero of Another Story: A HUGE story! Aku wants to catch this guy almost as badly as he wants to Jack.
- Hot-Blooded: He's one of the wildest characters of the show. His outrageousness is almost endless.
- Jerk with a Heart of Gold: He is an obnoxious, violent, bullying, rude, dimwitted braggart with a short fuse. But once you're his friend, there are no limits to his generosity and kindness.
- The Lancer: He's the closest thing Jack has to a best friend in this world.
- Large Ham:
- He's the second most-wanted man on the planet and will brag about it endlessly.
- In "Jack and the Scotsman Part II", he reveals that his clan are even more hammy than him. He doesn't stick around at home much because of that.
- Leg Cannon: A machine-gun! Doubles as Gatling Good.
- Lightning Bruiser: Despite being three times the size of Jack, he can easily match the samurai's speed to the point of them ending their fight in a standstill....three days later.
- Like Cannot Cut Like: Jack's sword fails to break his thanks to it having similar magical properties.
- Made of Iron: 2 robots bite him in both his arms - He just asks them if that's the best they can do.
- Man in a Kilt: It's definitely not for fanservice.
- Master Swordsman: He matches Jack blow for blow whenever they duel.
- No Name Given: In part because Jack never asked his name. (In fact, the writers didn't bother naming his wife or his clan as well.) Interestingly, he never refers to Jack by his name either, he refers to him as "my friend" or "laddie".
- Noodle Incident: It's never made clear how the Scotsman got to the position of 'most wanted man on the planet' (before Jack came along.) It's not a surprise, mind you, it's just not explained.
- No Sell:
- In "Scotsman Saves Jack Part II", an amnesic Jack, the Scotsman, and a bunch of pirates sail the ocean, only to come within range of the song of Enthralling Sirens. Everyone on the ship becomes hypnotized, except the Scotsman. Why? The fact is that the song of the siren enchants men due to how beautiful it is to their ears. The Scotsman thinks their singing is horrible.
- When a couple of robot alligators bite his arms, he chortles, "Is that the best ye can do!?"
- Odd Friendship: You couldn't find two people more different than him and Jack, yet he's overjoyed whenever they cross paths.
- One-Man Army: The more the merrier! Gives him a chance to use More Dakka and explosives!
- Red Oni, Blue Oni: The red to Jack's blue.
- The Rival: Friendly competition defines his relationship with Jack.
- Sickeningly Sweethearts: He and his wife. He describes how beautiful her singing is when confronting the Sirens.
- Super Strength: He's torn apart tanks, smashed buildings, etc.
- Took a Level in Kindness: After becoming friends with Jack.
- True Companions: In "The Scotsman Saves Jack", he dives headfirst into parts unknown all to help an amnesiac Jack get his memories back. He had nothing to gain by doing so, he simply did it out of loyalty to Jack.
- Unskilled, but Strong: Compared to Jack, who relies on several sword techniques and fast reflexes to overcome his opponent, the Scotsman simply attacks head on with everything he's got, simply shrugging off any attacks. He's still pretty skilled though, considering he's Jack's equal in swordsmanship.
- Violent Glaswegian: Uh... check out everything above.
- Walking the Earth: Similar to Jack, though his reasons for doing so aren't specified.
- Worthy Opponent: He's Jack's. The feeling is mutual.
Voiced by: Sab Shimono (Old), Keone Young (Young, Birth of Evil episode)The samurai lord who accidentally awakened Aku when he tried to destroy the corruption he was otherwise unconsciously causing. The gods Odin, Ra and Vishnu forged the sword that would later become Jack's from his righteousness. He manages to seal Aku, until he returns once again to unleash evil. Apart from the first episode and the two-parter covering him awaking and sealing Aku, he mostly appears in flashbacks.
- Annoying Arrows: Clearly disregards having been struck by some arrows during his fight with Aku.
- Badass: Not as much as Jack, but he still defeated Aku the first time.
- Badass Mustache
- Cool Old Guy: 'Birth of Evil' shows him when he's in his prime, but in his other appearances he's in his forties or fifties: a man of dignity, confidence and boundless courage.
- Determinator: Destroys the evil pool despite the seeming loss of his entire personal guard: then fights Aku to a standstill, whittles him down to a mere hateful specter and immediately begins planning in case this evil should ever return. Five years later, and he willingly goes to his destruction - fighting to the end - in order to give his wife a chance to enact that plan.
- The Emperor: Of Medieval Japan.
- Genre Savvy:
Be wary, my son, for evil finds a way.
- He doesn't rest on his laurels after he defeats Aku and traps him in the tree. He's well aware there's a good chance he could escape from his imprisonment. So he sets up a plan to have his son travel the world to be trained as a One-Man Army while his wife hides away in a monastery with the sword until he's old enough to use it.
- And even then he knows he knows it might not be enough. He says as much when Jack goes to face Aku for the fist time:
- Katanas Are Just Better: Of course the only reason this one is better is because it's forged by the gods from his righteousness.
- Nice Guy: Like his son, he is very kind and open to people and innocents.
- Lantern Jaw of Justice: Apparently it's hereditary.
- Nice Job Breaking It, Hero: On the upside, the pool of evil is no longer inexorably destroying all life. However, now it's got a consciousness, all of eternity to find a way to return, and a personal grudge against the family. Great.
- No Name Given: Much like his son.
- One-Man Army. He was able to fight the many clones of Aku.
- Papa Wolf: He was the protector of his people, until Jack grew up.
- Posthumous Character: Except for certain episodes that take place in the past, he's long dead in the present timeline.
- Reasonable Authority Figure: Among other things, he won't intercede to stop bullies from bothering his young son (in 'Jack Remembers'). That would be abuse of his authority.
- Royals Who Actually Do Something: He's actually an emperor, but that doesn't stop him from charging into battle when his subjects are in danger. Now you know where Jack gets it from.
- Samurai: Like his son after him.
Voiced by: Lauren TomThe wife of the samurai lord. Apart from the first episode and the two-parter covering her husband awaking and sealing Aku, she mostly appears in flashbacks and reminders of encouragement.
- Action Survivor: She escapes the kingdom while Aku is annihilating it, in order to get her son to safety.
- Badass Normal: She may not be a fighter, but that doesn't stop her from doing what needs to be done to get Jack on his quest.
- Not to mention she gives birth to her firstborn, in an age with no epidurals, on the ground in front of the charred palace with what looks like only her Handmaidens to assist her!
- No Name Given: As with the rest of her family.
- Posthumous Character: Just like the Emperor, she's dead in the present timeline.
The Canine Archaeologists
Rothchild III voiced by: Rob Paulsen
McDuffy voiced by: Jeff Bennett
Dreyfuss voiced by: Jeff BennettThree anthropomorphic dogs are dedicated to studying legends that their ancestors were once animals. They convince the samurai to save their land from a coming beetle droid invasion. Their names are Sir Dreyfuss Alexander (Bulldog), Sir Angus McDuffy (Scottish Terrier), and Sir Colin Bartholomew Montgomery Rothchild III (Dachshund).
- Nice Guy: They're all very friendly, helpful and polite.
- Non-Action Guy: Unlike the Tribe, the dog-people don't get trained in self-defense. However, they do everything they can to sculpt the battlefield and provide Jack with the armor, steed and additional weapons he needs to triumph. It's just barely enough.
The WooliesA race from a peaceful, utopian society who were conquered and enslaved by the Critchellites, using the power of the Black Sphere.
- And I Must Scream: The Black Sphere forces the Woolies into walking like animals and preventing them from speaking.
- Made a Slave: Their entire race was enslaved
- Space Jews: They even wear yarmulke-like hats in the flashback to their golden age.
- Took a Level in Badass: After being released by Jack, they stomped the Chritchellites easily.
Voiced by: Tom KennyA race of diminutive conquerors who enslaved the Woolies and took over their civilization, claiming it as their own.
- A Nazi by Any Other Name
- Faux Affably Evil: They seemed like very nice guys, inviting Jack to dinner and such, but when Jack found out that the Chritchellites were enslaving The Woolies, they turned out to be rather cruel and evil, and so they fought against Jack and the Woolies but were defeated.
- Kick the Dog: They're treatment of The Woolies.
- Laser-Guided Karma: Once the Black Sphere is destroyed, their weapons become useless, and the Woolies use their superior size to drive them off.
- Sadist: They tortured the Woolies, as well as enslaving and ordering them around.
- Shock and Awe: They use electrified spears as weapons (and encouragement to their slaves.)
The AstronautsA tribe of technology experts who were enslaved by Aku and forced to design and build his robotic forces. They've been constructing a secret escape rocket when Jack accidentally leads Aku's forces to their hideout. Jack promises to help protect the group, and in return, they promise to try and help Jack return to his own time.
- Ludicrous Precision: The guy with the calculator, calculating the odds of survival. Jack doesn't trust the math.
- Shout-Out: The Astronaut in the green helmet looks very similar to George Jetson.
The Three Blind ArchersThree incredibly skilled archers who guard a magical well at the top of an old tower.
- Annoying Arrows: Subverted. These are some serious, robot-puncturing, tank-demolishing arrows.
- Be Careful What You Wish For: The archers are actually three wanderers who made a wish to the Spirit of the Well to become "the greatest of warriors". The Spirit granted the wish, but in the process bound them to its will as mindless, sightless guardians.
- Bottomless Magazines: The three of them can fire hundreds of arrows in seconds, and never run out. (They don't carry quivers either, so in all likelihood, their bows magically create arrows.)
- Handicapped Badass: The three archers are blind, but still wipe out an entire army with no problem.
- Super Hearing: The Archers have incredibly sensitive, sonar-like hearing that gives them astonishingly accurate aim despite being completely blind. Their hearing is so acute they were able to fire arrows through Jack's sleeves just by listening to them gently flapping in the wind.
Voiced by: Phil LaMarr
Weary of those worthless bounty hunters, Aku created a dark version of the samurai in an attempt to finish Jack. Mad Jack is defeated when Jack meditates to seal him off, since he existed only as a manifestation of Jack's negative emotions.
- An Aesop: Jack does much better at containing his anger after the Mad Jack incident.
- Enemy Without: He's a manifestation of Jack's negative emotions.
- Evil Counterpart: Take a guess.

- Sheathe Your Sword: How Jack ends up defeating him.
- Jerk Ass: Possesses none of Jack's nobility or manners.
The TriseraquinsAn alien tribe who live in a floating city. Their city is menaced by Aku, who demands a simple price for sparing them...
- Atlantis Is Boring: At least, until Aku showed up.
- Et Tu, Brute?: They aren't inclined toward villainy, but they're being blackmailed.
The Lava MonsterA viking warrior whose kingdom was destroyed by Aku a millennium ago. Instead of killing him, Aku imprisoned him in solid crystal and buried him inside a mountain to deny him an honorable death. Over the centuries, he learned to shape the rock around his prison and formed a giant stone body. Now he lures other warriors to his mountain, seeking one strong enough to defeat him in honorable battle and grant him entry into Valhalla.
- Blood Knight: Jack initially thinks he is this, and for a measure he was right. But due to circumstances, he doesn't exactly enjoy killing people, but have no choice but to fight as his best as if he throws the fight, it will deny him entry into Valhalla.
- Death Course: Designs one to test his opponents. Notably a number of other warriors have succeeded before Jack, but none have succeeded in actually besting him in combat.
- Death Seeker: As he wishes to join his dead kin in Valhalla, he must die by honorable combat.
- Determinator: He was imprisoned in solid crystal and buried inside a mountain by Aku. Over the centuries, he learned to shape the rock around his prison through sheer willpower.
- Duel to the Death: The only way to be free of his curse is to lose one.
- I Die Free: His ultimate goal. Jack grants it to him.
- Lightning Bruiser: He's a stone giant who's quick enough to keep up with Jack in a swordfight.
- Rapid Aging: Upon being freed from the curse he rapidly ages from a young man to an elderly as he dies.
- Worthy Opponent: Sets up a Death Course to find one strong and skilled enough to beat him.
The GangstersA group of diminutive gangsters, supposedly working for Aku, that aren't very good at their jobs. They have more than a passing resemblance to the Ant Hill Mob from The Perils of Penelope Pitstop.
- Goldfish Poop Gang: They're not good for much. Even Aku seems aware of it.Aku: Who dares to summon the Mighty Aku, the Shogun of... oh. It is you.
- Hidden Depths / Offscreen Moment of Awesome: After knocking Jack out an instant before he could deliver a fatal blow to Aku, they somehow got Jack's unconscious body out of there without Aku being any the wiser (and without being punished for their role in bringing him there.)
- The Mafia: Played for laughs.
The Goddess of Water and the ElementalsA water goddess who created a powerful jewel that can control all the world's water supplies. To keep it safe from Aku, she created three elemental guardians, strong enough to drive Aku off though not enough to destroy him.
- Defeating the Undefeatable: The Goddess and her creations are among the very few who've ever been able to repel Aku.
The ChildrenKids that are fans of Samurai Jack and are part of Aku's fairy tales.
- Audience Surrogate: Particularly when they start to pick at the flaws in Aku's stories.
- Hero Worship: The kids love Jack.
TribeA tribe of round little white-furred apes (and a wild man who lives alongside them).
- Charles Atlas Superpower: The White Apes have an incredible ability to jump enormous distances due to a regimen of training that they go through.
- Not Quite Flight: Not flight, jump good!
- Raised by Wolves: The Monkey Man was originally part of a group of humans enslaved by Aku's forces, but was accidentally left behind by them as a young child, and was raised by the White Ape Tribe. He's well aware that he's human and not an ape though.
- Training from Hell: The training the white apes undergo to learn their Jump Good skill that they teach to Jack, which involves jumping, running and training with boulders tied to their arms and legs as well as an enormous one on their backs.
- Training the Peaceful Villagers: Jack trains the peaceful apes in nonlethal combat to help them defend themselves against an aggressive tribe of red gorillas that harasses them and steal their food. In return, they train him to Jump Good.
The Two-Headed WormA magical two headed worm who is said to be able to grant the wish of anyone who can guess its riddle.
- Blatant Lies: When one of them tells you that one head only tells the truth and the other only lies, it might be lying.
- Shaggy Dog Story: And then Jack discovered that the worm lied. The End.
The Metal Eating FamilyA family of lost travellers that are actually metal eating robots.
- Tomato in the Mirror: The family are robots, but don't seem to be aware of it.
- Big Lipped Alligator Moment: The last we see of them are the family literally eating eachother. No mention of them is ever made again (it's unknown if they were sent by Aku).
The GargoyleA brutish gargoyle who seals a magical fairy inside an unbreakable sphere, intending to force her to grant his wish.
- Evil Brit: A sort of Yorkshire accent.
- Taking You with Me: He laughs as he crumbles to dust, because he knows that Jack and the fairy are doomed without him.
The Wishing Fairy
- Damsel in Distress: Her tale starts when she's somehow captured by the gargoyle.
- Benevolent Genie: With a rather major drawback - only one wish, ever.
Dome of Doom Champions
Gordo voiced by: Kevin Michael Richardson
Aqualizer voiced by: Phil LaMarr
Sumoto voiced by: Kevin Michael Richardson
Ganeesh voiced by: Kevin Michael RichardsonNine champions that Jack has to face for freedom in the Dome of Doom. Their names are Gordo the Gruesome, The Aqualizer, Sumoto, Mr. Roboto, Miotis, Reptor, The Claw, Torto, and Ganeesh.
- Acrofatic: Despite weighing 700 tons, Sumoto can perform a vertical leap several hundred feet into the air.
- The Battledome: Exterior shots of the Dome of Doom are reminiscent of Thunderdome.
- Everyone Calls Him Barkeep: Jack is referred to as "Two-Sandals The Treacherous" in this episode, since that's what the announcer called him when he was hauled into the arena to face Gordo.
- Everything's Better with Monkeys: Gordo is a simian-like alien.
- Ice-Cream Koan: Everything that Ganeesh says
- Large Ham: Basically every fighter in the Dome of Doom with speaking lines, but especially Gordo and the announcer.
- Lizard Folk: Reptor and Torto.
- Multi-Armed and Dangerous: Ganeesh, who resembles a Hindu god.
- Screw This, I'm Outta Here!: Reptor hightails it out of the arena after Jack has cut off his extensible tongue and killed the other champions.
- Shout-Out: The Aqualizer is one to Blaster from Mad Max. Underneath his helmet, Aqualizer is actually a harmless, weak sluglike creature who can't fight on his own.
- The Tooth Hurts: Jack disables Miotis by cutting out his fangs.
- Unstoppable Rage: Gordo goes into a state like this when he's been hurt. It still doesn't do much to help him.
- Weaksauce Weakness: Sumoto, the most formidable of the champions, has one.
- Wolverine Claws: The Claw's signature weapons.
The Scotsman's Wife
Voiced by: Ruth WilliamsonMarried to the Scotsman. Not so much a 'skilled fighter' as an elemental force of raw destruction. And insults.
- Action Girl: When properly enraged.
- Badass: Defeated all the robots and sent Jack fleeing for his life.
- Badass Normal: She may not have any powers herself but she's not afraid to fight anyone who's powerful.
- Badass in Distress: Got saved by Jack and The Scotsman but capable of destroying the army that was on the verge of defeating them.
- Berserk Button: Refer to her size and you perish.
- Damsel in Distress: The least distressed damsel you can imagine, but still it was the plot of an episode.
- Eye Scream: Pokes several of the demons' eyes out.
- Fiery Redhead: Stereotypical Scottish temper.
- Flowery Insults: Even more skilled than her husband!
- Gonk: Her personality makes up for it, as long as she's in a good mood.
- Groin Attack: Responds to the Master of the Hunt calling her fat by punching him right in the clock schpiel.
- Hair-Trigger Temper: If you know what's good for you, do not make her angry. Hell, even the scotsman her own husband is afraid of just the thought of angering her.
- One Woman Army: Defeated the whole drone army who Jack and The Scotsman, who are Back-to-Back Badasses, were not even able to defeat together with their swords!
- Shockwave Stomp: She can create one of these by punching the ground.
- Unstoppable Rage: Destroys the entire demon army holding her captive with her bare hands (and feet, and teeth, and forehead...)
The Celtic DemonsA clan of demonic robots, or possibly robotic demons, serving the Master of the Hunt
- Ambiguous Robot: They're demons! With robot insides!
- Behind the Black: When Jack tosses a pebble to the gates of the Castle of Bone, five demons pop out of nowhere with guns at the ready.
Eight nigh-invulnerable killing machines that are design by Exdor as a means to kill Jack. Aku then empowers them and test by destroying Exdor's village and other villages to lure the samurai out. It took a metal gauntlet made by Extor and divine intervention for Jack to destroy them.
- A.I. Is a Crapshoot: Intentional, seeing as Aku is their power source.
- Famous Last Words: The lead bot can only think of one word when Jack cleaves him in half, with some divine assistance.Lead Bot: Unbelievable...
- Flamethrower Backfire: The robot with the flamethrower arms is destroyed when Jack cuts off one arm and ignites the robot's remaining fuel with it.
- Gatling Good: One of the robots has two gatling guns for arms.
- Invisibility Cloak: One robot uses a combination of this and a pair of close combat Power Fist.
- Katanas Are Just Better: The leader droid has a katana meant to simulate Jacks.
- More Dakka: The robots that uses projectiles for weapons uses this style of attack.
- No Sell: Exdor worked long and hard to make them a match for Jack, and as such his initial attacks aren't able to phase them. The sword isn't useless, it's just that Jack's physical strength isn't enough so Exdor gives him a robotic gauntlet that gives him the strength to cut through the robots. When the power for the arm runs out, Jack uses the power of his ancestors to give him a boost to destroy the last robot.
Voiced by: Jeff BennettThe creator of the Ultra-Robots designed to kill Jack, but Aku betrays him by sending his creations to destroy his village. He seeks to redeem himself by building a metal arm for Jack to destroy the robots.
- The Atoner: The robots he created are invincible: helping Jack is his effort at atonement.
- Expy: His name recalls Genndy's previous creation, Dexter: his voice is an homage to Jerry Lewis in The Nutty Professor (probably now better-known for another expy, Professor Frink.
- My God, What Have I Done?: His realization once Aku betrays him.
- Power Fist: A cybernetic arm he makes for Jack that gives him enough strength to cut through the Ultra Robots metal hide.
The Three Monks
Monk #1 voiced by: Corey Burton
Monk #2 voiced by: Kevin Michael RichardsonThree monks that have trained and meditated their whole lives to climb a massive mountain, atop which there is said a great Truth can be found.
- Maybe Magic, Maybe Mundane: Three passing mountaineers who wander past just as Jack needs to confirm his purpose in life? Or agents of the gods sent to remind Jack what is at stake?
- The Stoic: They're not talkers.
The Farting DragonA dragon with a massive intestinal problems whose daily expulsion of gas plagues a nearby city.
- Apologetic Attacker: She would love to stop inundating the nearby town with rancid vapors.
- Bigger on the Inside: A rare case where this applies to a living creature. When Jack crawls down her throat to deal with the problem, he finds a Womb Level that's as big as a decent-size cavern system, clearly bigger than the dragon seemed outside.
- Samus Is a Girl: Her voice seems masculine at first, until Jack discovers that the problem is a partially-hatched baby dragon in her womb.
- Visual Pun: To the Bruce Lee film, Enter the Dragon.
- Badass: They're amazing hunters. They were able to catch Jack and weren't afraid to tell Aku that they would set him free.
- Hunting the Most Dangerous Game: The samurai is worthy prey.
- Planet of Hats: A whole world of The Hunter.
- Proud Warrior Race: Their leader gives a laconic speech that explains this very succinctly. Aku was willing to pay them very, very well. They don't want the money: they want the hunt.
One of Aku's most powerful minions. He has the ability to summon the essences (souls) of countless warriors from his collection.
- Badass: Aku refers to Demongo as his best, strongest and most powerful servant: one who has never once failed to destroy any threat to Aku.
- Badass Boast. "I am the dealer of destruction, the merchant of doom! And I seek you, Samurai Jack."
- Blade on a Stick: The Samurai Warrior has one of these.
- Dark Is Evil: Just like Aku, he's a ruthless black demon.
- Catchphrase: "My Mastaaaah".
- The Collector: In this case, he collects and enslaves 'essence'.
- Hero Killer: He may be weak on his own, but he is still known for having killed hundreds of warriors and beasts and claimed their essence. He had to have killed at least one of them on his own to start his collection.
- Informed Ability: He was never really seen actually take someone's essence. Also, Demongo is refered as the most powerful minion of Aku, however the only power was from the essences of the warriors inside of him.
- The Jailer: Demongo is a unique example; not only is he a jailer (his victims being enemies of Aku) but his body is the jail, and he can command the imprisoned souls to fight for him. (Until, that is, Jack busts them out.)
- Noble Demon: He seemed very loyal to Aku, calling him his master and even seeking forgiveness from him.
- Noodle Incident: The first four warriors Demongo summons are recognized by Jack. Judging by their dialogue, he's met them before, but they had not actually appeared in the show before.
- Psychopathic Manchild: Demongo has shades of this, including sticking out his tongue and making silly taunts.
- Shout-Out: One of the warriors Demongo summons is very clearly one of the Teenage Mutant Ninja Turtles, just with a sumo wrestler outfit instead of a shell. Another heavily resembles Lobo and another Marshal Law.
- Squishy Wizard: His essence-stealing powers make him nearly unbeatable, but as he cheerfully admits, he has basically no fighting skill of his own.
- Your Soul Is Mine: Anybody killed by him or his imprisoned warriors joins them in his collection.
The SpartansAn army of Spartan warriors protecting their secluded homeland from an unrelenting force of robotic monsters.
- Determinator: Their response to the very real threat of a Forever War? Hold the Line.
- Proud Warrior Race: They realize that they are doomed, and they are committed to dying well.
- Royals Who Actually Do Something: The Spartan King leads his men from the front lines.
- War Is Hell: Especially one that can't be won.
The Mechanical Beast and Minotaur RobotsAn insane AI who's conquered all the lands surrounding its lair aside from the Spartan Kingdom.
- A.I. Is a Crapshoot: Possibly. On the other hand, Aku is the most likely source for the Beast's technology. It may be functioning exactly as he intended when it spreads ruin and desolation.
- Zerg Rush: The minotaur robots are simply sent in en masse, over and over. This isn't We Have Reserves, though: after each defeat they drag their fallen comrades or their own lost body parts back for repair.
- Badass: The guy was able to manipulate kids through music and fight with Jack.
- Bald of Evil: He's completely bald.
- Cool Shades: Wears a pair. They get destroyed after Jack beats him.
- Dance Battler: For the first part of the battle, allowing him to match Jack blow-for-blow.
- Dangerously Genre Savvy: All it took for him to realize Jack had infiltrated his rave was to spot Jack's katana sticking out from his disguise.
- Evil Sounds Raspy: Raspy, indeed.
- For the Evulz: Possibly the only reason why he has the kids raid the village.
- Gatling Good: When using his Powered Armor.
- Gold Tooth: Which can shoot lasers!
- Jive Turkey: He's a DJ, what do you expect?Jack: Music maker man! You're beats are bad!Salvatore: That's right, they bad!Jack: Not bad good! Bad bad!Salvatore: Whatever!
- Lean and Mean: He's rail thin.
- Musical Assassin: A DJ who uses hypnotic music to brainwash kids into raiding villages. Seems about right.
- Powered Armor: Uses a special wristwatch to create this from his DJ equipment.
- Red Herring: Invoked. When he first appears, he's covered in shadows and his headphones make him resemble Aku, but then the lights come on and reveal who he really is.
- Rhymes on a Dime: When ordering the kids to attack Jack.Salvatore: Let's mix it up with a taste of the bass! Beats in his face! The brand new hardcore track! Jack Attack!
- What Happened to the Mouse?: It's never made clear what happens to him after his fight with Jack. But considering what happens to those who fail Aku, he probably won't live long.
Olivia and her FatherTwo of the townsfolk affected by DJ Salvatores' dance beats.
- Brainwashed and Crazy: Olivia.
- Inelegant Blubbering: Olivia's father. Incessantly.
- Ruritania: Their village is vaguely Bavarian.
Josephine and Ezekiel ClenchA pair of married but separated bounty hunters who end up teaming by necessity to take down Jack. It doesn't help much.
- Bounty Hunter: Zeke has quite a reputation: Josephine's success relies on not having one.
- Chronic Backstabbing Disorder: Hinted at with Josephine.
- Hollywood Restraining Order: Hilariously, he took out a restraining order on her.
- Huge Guy, Tiny Girl and Ugly Guy, Hot Wife
- Improbable Weapon User: Zeke's gauntlets. Which turn out to be very multifunctional: pistols, Dual Wielding knives, bola launchers, tasers, and - of course - clenching.
- Like an Old Married Couple: Hell, they were married for a while.
- Revolvers Are Just Better: Josephine's weapon of choice.
- The Vamp: Josephine.
Dust ZombiesAn entire graveyard, resurrected en masse to take down Jack.
- Made of Plasticine: Most of them are reduced to powder with a single swing. But there are a lot of them.
- Our Zombies Are Different: Necromancy variety.
- Zerg Rush: They attempt to swamp Jack with sheer numbers over and over. It gets pretty harrowing.
The Minions of Set
The Minions of Set are three powerful divine beings created by the Egyptian god Set to bring violence and terror to the world. Incredibly strong, fast, agile and with a healing factor that makes them nearly invincible, the Minions are among the most deadly opponents Jack ever faces. Their appearance is loosely based on the Set Animal, or Sha.
- Badass: They are the personal servants of a god, and are not of the mortal world. They are stronger, faster, more agile and fight with more brutality than any opponent before them. In some ways they are even more powerful than Aku, as they do not share his weakness to the power of human righteousness, shrugging off strikes from Jack's sword like they're nothing. Jack admits they are the most powerful opponents he has ever faced up to that point (this was shortly before his encounter with the Guardian - see below.)
- Behind the Black: The entire episode makes extensive use of this technique for conveying the panicked, claustrophobic feeling of being surrounded by swift and powerful monsters, but not being able to keep track of where they actually are. The Minions frequently jump into and out of the black, leading Jack to suffer frequent surprise assaults from off-screen, being completely unaware of the incoming threat until it walks onto the screen, even if it is right in front him.
- Chase Fight: Jack is unable to engage the Minions for more than a few moments at a time without being completely overwhelmed, so most of the episode consists of the Minions chasing Jack through an ancient Egyptian temple.
- Combat Parkour: The Minions move with incredible grace and agility for such large and heavy creatures, and use this skill with deadly effect in battle, constantly pouncing at their opponents like animals, rapidly changing position to keep their victims off-guard, performing flips and wall jumps, and even running across the tops of of a long row of pillars, all with flawless precision and execution.
- Combat Pragmatist: The Minions of Set have no hesitation or remorse about doing whatever it takes to kill their prey, employing brutal tactics that make merely fighting dirty look admirable. They are predators, not warriors. They want to kill Jack, and they are going to do it one way or another.
- Complete Immortality: The prophecy concerning the Minions makes it quite clear they can only be destroyed by the power of a god, specifically, the Egyptian god of the sun. Failure to summon this god will lead to utter disaster as there will be nothing left that can possibly stop them. A strong enough warrior might be able to drive them back, but nobody will ever be able to destroy them.
- Curb-Stomp Battle: The Minions are so much more powerful than Jack that it isn't a Curb Stomp Battle so much as it is Jack using every ounce of his skill and power to extend his life for a few more seconds. Every encounter with them forces Jack to focus solely on defending himself, as the Minions' blitz-like battle tactics make them almost impossible to hit. Not that hitting them actually does anything.
- Deus ex Machina: Set up all through the episode. Jack can't stop these creatures - the best he can do is summon a Physical God that can.
- Establishing Character Moment: The moment Aku releases them from their prison, the Minions's first act is to mercilessly slaughter all of Aku's robots in a terrifying display of their strength, skill, and utter ferocity.
- Flaming Sword/Technicolor Fire: Each Minion has a weapon enshrouded in magical blue flame. When they're finally subjected to a power that can hurt them, their bodies boil away with the same eldritch fires.
- Glowing Eyes of Doom: The Minions of Set have glowing blue eyes that shine more brightly whenever they become alerted or agitated during hunting. Even when passive their eyeglow is so bright it is clearly visible even in broad daylight in the desert.
- Healing Factor/Nigh Invulnerable: The Minions have an incredibly powerful healing factor that immediately heals any wound. Even Jack's sword (which has a very good track record when it comes to destroying the indestructible) is not effective: at one point he delivers a vital hit that nearly cuts one of them in half, and it grows back together the instant he finishes his stroke.
- Implacable Man: Quite possibly the Minions' most terrifying attribute. They are stronger than you. They are faster than you. They do not need to eat or sleep or stop to catch their breath. There is no stopping their rushing, headlong advance. Jack is hunted down relentlessly, barely able to stop running for even for a few moments before the Minions catch his scent and begin the chase anew.
- Knight of Cerebus: The Minions have no comedic traits and are possibly the most dangerous enemies in the whole show next to Aku.
- Lightning Bruiser: Despite having hugely overbuilt upper bodies, very short, slender legs and enough weight to make the ground rumble beneath their feet, the Minions of Set are extremely fast and agile. Jack is so overwhelmed by the way they constantly jump around in combat he can hardly tell what direction their attacks are coming from.
- No-Holds-Barred Beatdown: One of the main reasons the Minions of Set are so fearsome is that every second of their existence is a No-Holds-Barred Beatdown. They will immediately attack anything that moves with animal ferocity and machine-like determination, and will not hesitate to completely mutilate their practically helpless victims in their attempts to kill them.
- No-Nonsense Nemesis: Another reason the Minions are so terrifying is that they are utterly relentless. Once given an objective, they will stop at nothing to complete it. They don't need to rest, eat, or drink. They don't stop to banter, gloat, monologue, or snark. They don't allow Jack a chance to catch his breath. They use every underhanded tactic at their disposal. And they definitely don't let things like collateral damage stop them. They're out to kill Jack, they will kill Jack, and they Will. Not. Stop. Ever.
- Oh Crap!: Jack's reaction upon discovering the Minions' empty tomb. The normally calm and collected samurai is so horrified by the revelation he is frozen in place, gawking, allowing the Minions to ambush him.Jack: "The Minions of Set!'"
- Perpetual-Motion Monster: The Minions of Set appear to be completely immortal and invulnerable, require no sustenance whatsoever, and have unlimited stamina and endurance, allowing them to pursue their prey constantly and relentlessly without a moment's pause or hesitation. As powerful as Jack is, he is still only a man, and without the required items to summon Divine Intervention, it is only a matter of time until the Minions finally overpower him and tear him to pieces.
- The Nose Knows: They can sniff out Jack from virtually anywhere.
- Run or Die: Jack's only options when faced with immortal, unstoppable ancient Egyptian hell-beasts. And running only delays the inevitable.
- Sealed Evil in a Can: Originally plagued ancient Egypt until the Pharaoh of the time summoned Ra and had them sealed away inside a stone sarcophagus. Aku releases them in the present to kill Jack.
- Super Strength: The Minions of Set are huge and very muscular, allowing them to cut stone pillars to pieces, punch a person hard enough to send them flying through the air, and slam a person into a stone wall with enough force to leave a centimeters-deep impression of their body in it. Even their relatively short and slender legs are deceptively powerful, allowing them to run and move with great speed, make huge leaps and perform other acrobatic feats with ease.
- The Power of the Sun: The only thing that can harm the Minions is joining together three pieces of a magical scarab, which summons Ra, the god of the sun.
- The Speechless: Although they appear to be capable of understanding human speech, the Minions themselves do not speak, they only bark, growl and roar.
- Unskilled, but Strong: Not unskilled per se, but rather their impressive skill in battle is directly dependent upon their incredible strength, agility, and especially their invincibility. There is no need to learn to wield exotic weapons or employ specialized fighting techniques when you are an unstoppable monster. Contrast this with the Guardian, who while incredibly powerful, is neither invincible nor immortal and hence needs to actually know how to defend himself in combat.
- Victory Pose: After utterly annihilating Aku's robots, the Minions raise their weapons to the sky in triumphant celebration of their victory and prowess. The Minion with the battle axe even throws a fist pump in for good measure.
- Wall Crawl: The Minions are capable of running on walls and even upside down on the ceiling.
- Wall Jump: Several of them, actually. Being able to magically stick to walls and ceilings helps.
The Chosen One to find and use it. When Jack finds the portal, he is told by the Guardian that he's not the one, leading Jack to try and beat him anyway.
- Always Someone Better: Has Jack's number in combat. In fact, he has everyone's number. The Guardian has triumphed over hundreds of enemies for countless eons.
- Amazing Technicolor Population: He's blue.
- Badass: Being one of the only characters in the series that actually beats Jack in single combat has to count for something. He has annihilated war machines whose thumbs alone are bigger than Jack's entire body.
- Badass in a Nice Suit: He's very fond of his suit too.
- Bald of Awesome: He's about ten feet tall, very blue, and very bald.
- Beef Gate: A rare example outside video games.
- Berserk Button: Jack demolished his suit. He lost his temper, and Jack went from 'losing' to 'being brutally smacked down'.
- Blood Knight: He has a child-like delight in battle.
- Curb-Stomp Battle: Things stop looking equal pretty early on, and Jack's favorite solution against a skilled foe - turning an enemy's aggression against him - turns out to be a No Sell. Things get really bad for Jack. The only reason the Guardian doesn't kill him is because the portal gives him a sign telling him not to.
- Dual Wielding: First dual wields sai, then switches to dual wielding firearms.
- Extreme Omnivore: It's not shown whether he actually needs nutrition in all those eras of fighting, but after he loses his temper with Jack he eats his shield.
- Guns Akimbo: One a submachine gun, the other a machine gun/rocket launcher. At one point he's shooting throwing stars out of the air, unerringly, with his off-hand while continuing to blast at Jack with the other.
- Ha Ha Ha No: This is his response to Jack's request to use the time portal.
- He Is Not Ready: Is told this about Jack after their battle.
- Jive Turkey: Not as extreme as Da Samurai, but the Guardian does have this general speech pattern.
- Improbable Aiming Skills: He has blatant Hero-Tracking Failure when it comes to hitting Jack, but was able to shoot a dozen small projectiles out of the air at once.
- Lightning Bruiser: Tougher, stronger, and faster. He's toying with Jack.
- Master of All: Even moreso than Jack, because he even uses modern weapons. We see him use a katana, sai, a spear (broken into two halves for dual-wielding), machine gun, a rocket launcher, and eventually his bare hands.
- My Favorite Suit: Jack really shouldn't have damaged it.
- Nigh-Invulnerability: Missiles don't as much as scratch him.
- No-Holds-Barred Beatdown: Leaving Jack a broken, unconscious mess.
- No Name Given: The legend of the time gate in the Land of Moon refers to 'a guardian'. Hence his moniker: his true identity is left completely mysterious.
- The Only One Allowed To Defeat Me: He states that only one man will ever use his timegate - the same man that will defeat him in battle.Guardian: And you, m'man, ain't that man.
- Outside Context Obstacle: At some point, long ago, the portal was built (possibly by Aku, though probably not). Then somebody or something (definitely not Aku, or there wouldn't be an exception for 'the chosen one') stationed the Guardian there. Where'd he come from? Who gave him this task? And is he there to keep Jack in the future until 'future' Aku is defeated, or for some other reason? We don't know and we never will.
- Pet the Dog: When he thinks Jack's will to fight has finally been broken: "Now why don't you leave before you really get hurt!?"
- Red Eyes, Take Warning: He's not malicious, but those red eyes (lenses?) are indeed a warning.
- Shout-Out: His appearance, usage of a Katana, and the way Jack is reflected in his eyes are all reminiscent of Morpheus from The Matrix.
- Super Strength: As if his Hyperspace Arsenal wasn't enough.
- Tennis Boss: Subverted; Jack thinks he can beat him by bouncing his missiles back at him, but he's sadly mistaken.
- Time Abyss: The Guardian claims to have been guarding the time portal for "countless eons". The huge pile of rubble, debris, broken down giant robots, war machines and likely countless dead warriors surrounding the gate makes it obvious he has been doing this for a very long time.
The CreatureA hulking cartoony-looking creature of limited intelligence but benevolent nature that Jack finds and unwittingly befriends during his travels. Whilst it is initially annoying, when it sees Jack in pain at the hands of a band of robot bounty hunters, it reveals a far more violent side of itself and rescues him.
- Beware the Silly Ones: See Hulking Out below.
- Cartoon Creature: It looks something like a bear, something like a cat, and it's light blue all over. At best, one can say it looks vaguely like a blue Totoro with three daisies on its head.
- Gentle Giant: It's normally sweet, docile and inoffensive, if annoyingly dimwitted. But, for the love of all that's holy, do not tick it off!
- Hulking Out: When Jack is in danger, it undergoes a terrible transformation, growing several times larger, sprouting immense claws and a huge array of fangs, turning red with mad-looking eyes, and having its daisies replaced by dead-looking treestumps.
- Unstoppable Rage: Utterly mangles the robots who hurt Jack.
Roadster RobotsA team of 50s-themed robots who manage to get the better of Jack with a lucky shot. Unfortunately, it happened while the Creature was still in earshot.
- The Fifties: All four robots are built to resemble 50s teenagers - greaser hairstyles, poodle skirts, beanies, etc.
- Giant Space Flea from Nowhere: Bounty hunters? A roving team of killbots? Maybe they just hate kimonos? Who knows?
- Mook Horror Show: The Creature leaves them in fragments.
CronusThe Greek god of time and space. He was defeated eons ago by his son Zeus and was chained to an abandoned planet in space, while his magical gloves and helmet were hidden on Earth.
The Demon SpiritA malicious spirit that trap the souls of a family which sets in a haunted house. Jack manages to slay the demon and freed the family inside.
- Animalistic Abomination: Its true form resembles a cross between a humanoid wolf and a dragon.
- Attack of the 50-Foot Whatever: Grows to massive height during the last leg of its fight with Jack.
- Cool Sword: Another weapon it uses in its fight with Jack.
- Dark Is Evil: It's a demon that feeds on souls who initially looks like a black mass of shadows.
- Deliberately Monochrome: It's realm.
- Diabolus ex Nihilo: It's never been made clear what this thing is or where it came from.
- Drop the Hammer: One of the weapons it uses to fight Jack is a flaming hammer.
- Eldritch Abomination: Possibly the most straight up example next to Aku. It's quite powerful, feeds on souls, doesn't look remotely human, and is probably not even sentient.
- Flaming Sword: Its preferred type of weapon.
- Giant Space Flea from Nowhere: This creature is independent from Aku's services and is basically just a random Villain of the Week.
- Green Thumb: Takes control of some of the vines in the house to bind Jack so it could steal his soul.
- Hoist by His Own Petard: Twice. First, whenever Jack landed a decisive hit, the demon would grow larger to get the advantage. Jack eventually learned to use his willpower to do the same. The demon then tried to finish him off with a homing fireball. Jack grabbed it and tossed it back at him, killing him instantly and freeing the souls of Kuni's family.
- Humanoid Abomination: In its true form.
- Kick the Dog: After devouring the souls of her family, the demon let's Kuni live solely to use her as bait to lure in more victims.
- Knight of Cerebus: One of the few beings in the show that is taken completely seriously. Its episode is possibly one of the scariest in the whole show.
- Make My Monster Grow: The demon grows in size whenever Jack lands a decisive hit on it.
- Mind over Matter: Has telekinesis.
- Nothing Is Scarier/The Spook: Possibly the most terrifying aspect of the creature is how little we know about it. What is it? Where did it come from? Why did it target that family? What did it want with Jack? Is it affiliated with Aku? And is it even sentient? None of those questions are answered and it more or less just is, which serves to make it all the more unsettling.
- Playing with Fire: It can control fire, usually to create weapons.
- Reality Warper: Possibly hallucinations, possibly not. The demon can take full control of the house and its surroundings, such as making doors and windows vanish or casting illusions to make the house look more pristine. However, it's not perfect as when it tried to fool Jack by using the souls of the family, the disguise faltered quite quickly.
- Spontaneous Weapon Creation: It can create weapons out of fire.
- Super Smoke: Its initial form.
- The Voiceless: It never talks and mostly growls and roars.
- Your Soul Is Mine: It feeds on souls. And from what was shown during Jack's imprisonment, the family might have been its most recent victims.
The Shaolin MonksPractitioners of the ancient art of Shaolin kung fu, hidden away in an ancient temple. Their order is in fact the same that once trained Jack, and their Grandmaster met Jack himself thousands of years before. He's still alive, now being sustained by the very Earth itself, and offers sanctuary to Jack, as the temple is shielded from Aku's view.
- Hidden Elf Village: Their dojo is undetectable, but they use it as a sanctuary and a place of training, not a base: they aren't actively fighting Aku.
- Wacky Wayside Tribe: More significant to Jack than most, since they're one of the few surviving bits of the Earth he remembers.
The Labyrinth Thief
Voiced by: Rino RomanoA nameless expert thief who is after the same magical diamond that Jack is.
- Badass in a Nice Suit: Does his burgling in a white suit.
- Enemy Mine: There are a couple of occasions where they have to cooperate against the pyramid's defenses.
- Expy / Composite Character: Of Daisuke Jigen and Arsène Lupin III from Lupin III. His suit and hat are white instead of black, and he uses a briefcase that doubles as a machine gun rather than a conventional firearm, but the style of his suit and beard are identical to Jigen's. His personality, on the other hand, is based more on Lupin's behavior.
- Friendly Enemy: He seems to regard Jack as an interesting complication in a job that might otherwise have been boring.
The NinjaA robotic ninja clad in black sent by Aku to destroy Jack.
- A.I. Is a Crapshoot: Turned on its creators for no stated reason.
- BFS: Not too big compared to it, but its sword is as big as a building.
- Determinator: Even with its head crushed and three limbs gone, it still tries to kill Jack.
- Eye Beams: Among many, many other weapons.
- Humongous Mecha: It dwarfs skyscrapers. Jack is an ant compared to it.
- More Dakka: A massive armory of guns, missiles, and energy weapons are at its disposal.
- Shockwave Stomp: It's so huge every step it takes warps the ground.
- Shout-Out: Its orange armor and green visor make is resemble Samus Aran.
Voiced by: David Alan GrierA loudmouthed samurai wannabe who challenges Jack to a duel to prove he's the better fighter. Their duel is a comical mismatch. Watching Jack fight a real threat, and his humble personality and behavior, sets Da Samurai down the path towards true enlightenment.
- Attention Whore: He is constantly obsessed with people thinking of him as a samurai.
- Break the Haughty: His duel with Jack and the humiliation that followed it made him change his ways and try to become a genuine samurai.
- Butt Monkey: His actions make him this.
- The Bully: He was introduced as this until Jack taught him a lesson.
- Chewing the Scenery: He loves attention.
- Crouching Moron, Hidden Badass: To his credit, he did take out a group of robot soldiers with relative ease. He's not completely unskilled, rather a big fish in a small pond who became full of himself due to never fighting anyone stronger than him.
- Curb-Stomp Battle: Stands no chance against Jack in their "fight".
- Defeat Means Friendship: In this case, defeat brings humility, which brings respect.
- Fake Ultimate Hero: He learned this the hard way. Seeing Jack in action, though, kept him encouraged.
- Heel-Face Turn: He was never evil, but he bullied the people he protected and forced them to give him things for free in return for defending them. After Jack shows him what a real samurai is like, he starts to try to act more like one.
- Humiliation Conga: His entire fight with Jack knocks him down a few pegs.
- Jerkass: He has no manners towards others.
- Jerk with a Heart of Gold: He's not a bad guy, which Jack seems to notice. By the end of the episode he seems to be getting better.
- Jerkass Façade: Da Samurai acted like a jerk because he thought that it made him look like a samurai. Jack proved him wrong, which made him realize that he wasn't '"so bad after all".
- Jive Turkey: Biiiiig time.
- Taking the Bullet: His first step toward being a true hero was pushing Jack out the the way of a stun ray. Jack acknowledged him for it.
- Took a Level in Kindness: By the end of his episode.

The Gentleman voiced by: Daran Norris

- Badass Princess: Mira.
- Badass Baritone: Jujunga.
- Badass Boast: The Gentleman: “Now I’m not one to brag, but my blades are faster than any bullet.”
- Camp Straight: The Gentleman is a flamboyant dandy, but gets an intrigued grin when he sees their sixth partner is a woman.
- Cats Are Mean: The feline aliens, I and Am
- Cultured Badass: The Gentleman is dignified at all times and comes off as being rather posh.
- Curb-Stomp Battle: Jack takes out all six of them in the amount of time it takes a drop of water falling from an icicle to hit the ground.
- Creepy Twins: I and Am are distinctly creepy.
- Dressed to Kill: The Gentleman.
- Dual Wielding: The Gentleman carries two throwing knives, and Boris fights with two huge clubs.
- Dumb Muscle: Boris.Boris: Any questions?!Mira: Have you always been this stupid?Boris: Yes!!
- Five-Bad Band:
- He-Man Woman Hater: Boris does not like taking orders from "Wo-man".
- Husky Russkie: Boris is Russian in the same way that the Scotsman is Scottish: five hundred percent.
- Iaijutsu Practitioner: Mira can draw her sword and slash a drop of water falling from an icicle.
- I Gave My Word: "The Gentleman never goes back on his word".
- Knife Nut: The Gentleman.
- Large Ham: The Gentleman and Boris are both good examples. The others are much less prone to brag and posture.
- Mighty Glacier: Boris is enormous, strong, and very tough. But he's not very quick.
- Overshadowed by Awesome / Foregone Conclusion: The Gentleman; I and Am; Boris; Jujunga; and Princess Mira are six interesting, well designed, badass characters. Six of the best bounty hunters in the world. But we know who they're up against.
- Pint-Sized Powerhouse: Mira. She’s not even half Boris’ size, yet she punches him across the room.
- Rhymes on a Dime: I and Am.
- Samus Is a Girl: Mira provides the most straightforward example since, well, Samus.
- Sesquipedalian Loquaciousness: The Gentleman.
- Single-Minded Twins: I and Am seem to share the same mind. Even if this isn't true, they can certainly communicate with each other telepathically.
- The Smurfette Principle: Mira is the only female member of the group.
- Third-Person Person: Boris and the Gentleman do this sometimes.
- Unskilled, but Strong: Boris doesn't care much for technique, but he's certainly good at smashing things. He's at least smart enough to use this to his advantage — his strategy is to tank hits long enough to get into smashing range.
- Walking Shirtless Scene: Jujunga.
Siren #1 voiced by: Jennifer Hale
Siren #2 voiced by: Janine La Manna
Siren #3 voiced by: Tara Strong
- Enthralling Sirens: They are all beautiful and have eerily enchanting voices.
- Evil Cannot Comprehend Good: They're confused why the Scotsman is unaffected by their singing.
- Impossible Hourglass Figure: Carried to an extreme.
- Make Me Wanna Shout: Ordinarily, they use their voices to lure men to their cave, but they can weaponize their voices in other ways.
- One-Winged Angel: And in that form, they're one creature, not three.
- Our Monsters Are Different: Unlike classic sirens, these sirens are a three-headed monster disguised as three beautiful women.
Prince Astor and Princess Verbina
Prince Astor voiced by: Matt Levin
Princess Verbina voiced by: Tara Strong
- Expy: Aside from their butterfly designs, they borrow heavily from Luke Skywalker and Leia Organa.
- Heavy Worlder: Inverted. Their home world has less gravity than Earth, making them seem weak on Earth. In a similar gravity to their home world, they are great fighters.
The Seasons of Death
Spring Sprite voiced by: Grey DeLisle
- Fairy Sexy: Attractive. But wicked.
- Secret Test of Character: She tempts Jack to give in to his weariness and leave the fight against Aku to others.
Voiced by: Daran NorrisA retired enforcer robot with emotions. He was blackmailed into targeting Jack. See, Aku had kidnapped the one thing dear in the robot's life: his precious dog LuLu... sweet thing.
- A Boy and His X: A Robot and his Dog.
- Anti-Villain: Type II. Depends on how you view his mission.
- Badass in a Nice Suit: You have to admit, this robot has style.
- Bottomless Magazines: Averted, but due to spare magazines stored in his arms with a special mechanism to reload his guns, he can reload very quickly, without even a one-second break in concentration.
- Failure Is the Only Option: The series isn't named Robot Assassin X9... and Lulu, Sweet Thing. You know it's going to end in heartbreak.
- Film Noir: His episode is a salute to the genre.
- Forced Into Evil: He started as a robot that just followed his instruction commands. Later, Aku forced him to fight Jack by kidnapping his dog.
- Genre Savvy: He's seen Jack's handiwork against the bug-bots and knows that he fighting him is likely hopeless, but for Lulu's sake he goes in anyways.
- Glowing Mechanical Eyes: Seem to be Red Eyes, Take Warning, but they're actually just part of his model design.
- Guns Akimbo: To go with his mobster look.
- Heel Realization: Because of his emotions, he came to understand how immoral Aku was and left to live in peace, and he went largely unnoticed because Aku's evil scientists replaced the X series robots with the bug-bots seen prominently in many other episodes.
- Heroic Bloodshed: The bot may have been serving a greater evil purpose, but he was still only trying to save his dog.
- Hitman with a Heart: Provides the current page image!
- Homage: X9's robot form looks very similar to the T-800 endoskeleton from The Terminator, and has a similar purpose; both robots were built for violence and to enforce the will of an evil overlord. In addition, both are considered obsolete models in their respective franchises.
- Implacable Machine: It's been his job for a long time.
- It Amused Me: As X9 explains, the scientist who gave him the "experimental emotion chip" did so simply because, "He was kinda funny that way."
- Just a Machine: Possibly averted due to Jack's reaction after X9 muttered his dying words.
- Killed Off for Real: Inevitably, after a tension-filled confrontation, Jack catches X9 while his back is turned and runs him through. Because X9 refused to back down for the sake of Lulu, Jack had no choice but to finish off X9 before the robot did the same to him. X9's final request was for Jack to find his precious Lulu and take care of her before he went offline for good.
- Last of His Kind: The rest of his series were destroyed one by one as the years went by. Plans to build more were eventually scrapped in favor of the bug-bots.
- More Dakka: Of the pistol variety. Only once do we see him actually taking a accurate shot.
- One Last Job: The whole plot of the episode. Aku blackmails him into doing it.
- Personality Chip: His greatest strength and biggest flaw.
- Sliding Scale of Robot Intelligence: Average Joe Android. What he lacks in social skills he makes up for with musical ability and love for his dog.
- Sugar and Ice Personality: A calculating robot with a soft spot for puppies.
- Super Prototype: Thanks to his emotion chip. In a way it was a prototype within a prototype.
- Trench Coat Brigade: The last surviving member of one, anyway.
- Verbal Tic: "Lulu... sweet thing."
- What Measure Is a Mook?: Flip-flopped - it's made clear that most of Aku's army really are just killing machines that need to be destroyed. X-9 is an exception, but of course there's no way for Jack to know that until it's too late.
- What Measure Is a Non-Human?: Played straight and very strongly.
- Badass and Baby: Jack has to deal with some robot trolls while simultaneously seeking out the baby's parents.
- Troubling Unchildlike Behavior: Jack apologizes when he finds the child's parents, explaining that 'your son has seen death.'
Odin, Ra, and Vishnu
Odin voiced by: Richard McGonagle
Ra voiced by: Daran Norris
Vishnu voiced by: Daran NorrisThe three deities that fought and exterminated the black mass that spawned Aku eons ago. They are the ones that crafted Jack's sword: the one weapon that can harm Aku.Ra is also summoned to save Jack from the Minions of Set.
- Big Good: They're the only thing Jack has to offer prayer to.
- The Plan: Obviously they have a long-term plan for the destruction of Aku, and for some reason can't move to destroy him directly. There's no clue whether Jack's disappearance was seen as a failure of the "magic sword" strategy, but they're still backing him up (in ways Aku can't detect) now that he's back.
The Giant, Black Mass of EmptinessAn Eldritch Abomination that Odin, Ra, and Vishnu destroyed at the beginning of the Origins Episode.
- Apocalypse How: Attempted to cause a Universal-scale one.
- Eldritch Abomination: At least Aku has a visible form, this thing is basically a giant, semi-sentient blob.
- Generic Doomsday Villain: It wanted to devour the universe, it was killed by Odin, Ra, and Vishnu, and it is the source of Aku. That's all we know of it.
- Greater Scope Villain: Aku was spawned from a fragment of this being.
- Satellite Character: It merely serves as the source of Aku.
