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 have 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.
  • The Abyss Gazes Also: While fighting his Evil Counterpart in "Jack versus Mad Jack", their blades cross, and Jack sees his eyes reflected: they look just like Mad Jack's. Realizing that Mad Jack was born from his inner rage, Jack immediately stops fighting, causing the forest fires to die out. He calmly tells Mad Jack that he has lost, and the anger that created him is now gone, therefore Mad Jack no longer exists.
  • The Ace: He's seen learning more and more, and as the show progresses, he's always getting better at things.
  • The Ageless: He hasn't aged during the fifty year Time Skip, a side effect from traveling through time.
  • Aloof Ally: Jack is one to most of the characters, including the Canine Archaeologists, the Woolies and even the Scotsman, despite the latter being his best friend.
  • 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.
  • Aside Glance: He's somewhat prone to this, on occasions when he is so perplexed that a simple confused stare wouldn't be enough.
  • Atop a Mountain of Corpses: He ends up standing atop a mountain of robot corpses after defeating them.
  • Back-to-Back Badasses: He and The Scotsman ever since the first time the two started working together.
  • Badass Adorable: While he's not adorable in the strictest sense, he has his moments of vulnerability and heroism that qualify. Besides that, his adventures as a child, particularly "Young Jack in Africa", showed how much of a badass he was even as a cute kid.
  • Badass Back:
    • Just trying to attack him from the back will get you sliced in half.
    • Best shown in his 'fight' with Da Samurai: Jack intentionally keeps his back to the guy most of the fight. He still completely stomps him into the ground without even trying.
  • Badass Beard: In Season Five, he sports a prominent beard.
  • Badass Biker: A Season Five preview shows him as one, with a bitchin' Cool Bike that he uses to dismantle Aku's Mecha-Mooks.
  • 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, so he always wears a long white robe. How he cleans, fixes, or replaces his robe after getting it dirty or torn up from so many battles is unknown.
  • 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: While Jack usually handle fight via violence, there have been moments where he defeats his enemies without said violence.
    • Jack defeats Mad Jack simply meditating and controlling his emotions.
    • In one of his fights at the Dome of Doom is the huge sumo wrestler, Sumoto. Jack, getting tired of fighting for entertainment, refuses to fight Sumoto. Jack still win their duel. By simply tickling Sumoto.
    • A flashback into his childhood has a young Jack dealing with a trio of bullies who took his toy from him. He managed to get it back by scaring a group of pigeons that distracted them long enough for a young Jack to retrieve his toy.
  • Bash Brothers: With The Scotsman.
  • Batman Grabs a Gun: As of season 5 Jack has been stuck in the future for fifty years and no longer has any issues using a gun, grenades, and other futuristic weapons.
  • Beard of Sorrow: 50 years wandering the future with no success will do that to you.
  • 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.
    • Confirmed by the new season, which is to be premiered in early 2017: it will take place 50 years after season 4, and Jack still has yet to return to the past.
  • 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.
  • Big Good: As the polar opposite of Aku, of course he is.
  • 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. As of Season 5 however, Jack plays this trope very, very straight, due to the series becoming Darker and Edgier and premiering on [adult swim]'s Toonami block.
  • Character Development: Several times during the show.
    • In the first few episodes of Season 1, though he was still calm and level-headed, he was also short-tempered, and quick to anger. In "Jack vs. Mad Jack", his anger grew consummately, and was seen losing his temper and morals. However, after fighting Mad Jack for some time, he realizes that it's just an illusion of his anger. Afterwards, Jack learned how to control his anger, he is seen being a lot less hot-headed, and is very slow to anger.
    • At first, he couldn't jump up high enough to reach Aku. However, after meeting the Monkey Man, he learns him to jump that high, or as they say, jump good.
    • By season 5, he looks and sounds very tired. 50 years of basically zero progress on his quest has obviously took its toll on him.
  • 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 Coats Are Off: The Clothing Damage he suffers is usually a sign he's in for a serious fight, which he'll oblige by ripping part or all of his robes off. Being Jack, you can probably expect the other combatant's soon to get their ass handed to them.
    • Subverted Trope in "Jack versus Mad Jack", where his robe gets torn but he keeps it on throughout the fight. It fits with him ending the fight instead by simply calming his anger and causing the hatred that Mad Jack was born of to no longer exist rather than defeating him in combat.
  • Combat Pragmatist: Seems to have become this by Season 5, which is in stark contrast to his Honor Before Reason tendencies in earlier seasons. He's ditched his robe for armor and has no problem using weapons such as guns, grenades, and tridents. This is no doubt a result of being trapped in a Bad Future for decades.
  • 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 topknot. Once that pin's gone, you get some long, flowing locks that couldn't possibly fit into his tied-up hairstyle.
  • Consummate Liar: He frowns on deception, but he can be a pretty good liar when he needs to be.
  • Cool Helmet: Wore one in the pilot.
  • Dark and Troubled Past: Witnessed his home being taken over by Aku, including his father being kidnapped by the demon. He then spent the next years training in order to prepare for his destined fight against the shapeshifting monster.
  • Despair Event Horizon: He appears to have hit it by season 5. Having wandered the future for fifty years without aging or getting any closer to finding a way home has visibly worn him down.
    Jack: There's no way home! There's nothing to fight for!
  • 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. The fifth season pilot emphasizes this, which Jack clawing himself out of a Heroic B.S.O.D. and saying, "It always seems bad at first, but then I find a way," before starting to kick serious ass.
  • 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.
  • 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.
    • The season 5 pilot reveals that, due to the side-effects of time travel, Jack is The Ageless.
  • Everything's Better with Samurai: He is a samurai, he is The Hero, and he kicks tons of ass.
  • Evil Knockoff: Mad Jack, a being that was created from Jack's negative emotions.
  • 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, though he does spend a lot of time looking confused. As of season 5, he's fully adapted, and is shown in the trailer riding a Cool Bike and using guns.
  • Force and Finesse: The Finesse to the Scotsman's Force. While both are Master Swordsmen, Jack is the faster, more skilled, and cunning of the two, while the Scotsman is stronger, tougher, and better with modern weaponry.
  • 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.
  • Free-Range Children: Flashbacks of his childhood before Aku entered, showed that Jack was free to roam in his home despite being a prince.
  • Friend to All Children: While he doesn't interact with children often, he'll help out any he comes across. This is most notable in "Jack is Naked" (where he sympathizes with the orphan girl stealing his gi and retrieves some robot slug tusks so that she can sell them for money and be able to afford food) and in "Jack and the Baby", where he rescues a baby from being eaten by ogres and spends the rest of the episode getting the child back to his parents while also doing everything he can to tend to the infant's needs and keep him from crying.
  • Future Badass: Shown briefly by the Guardian's time portal. Not that we needed any confirmation, but season 5's trailer has proof.
  • Good Is Not Dumb: While he's not being hindered by Chronic Hero Syndrome, he's shown he can be very clever.
  • Good Is Not Soft: A sworn protector of the innocents and the biggest threat to all evil villains.
  • Hat Damage: Whenever he wears one, it's usually the first thing to go.
  • Heroic Self-Deprecation: The fifth season pilot shows him sinking heavily into this and doubting his purpose, only to claw himself back up and regain it.
  • 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.
  • Hope Bringer: He's given the oppressed masses someone to rally behind against Aku.
  • 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 matter 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. Judging by the looks of Jack's father (see below), it seems to run in the family. Both the jaw and the justice things, that is.
  • Light is Good: Besides wearing all white and being contrasted against dark enemies, he apparently also knows a very specialized form of ninjutsu that allows him to blend in with the light. His Evil Knockoff, naturally, replaces the white and darker grey in his robes with Red and Black and Evil All Over.
  • Limited Wardrobe: Always appear to be wearing the same white gi - 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 robes.
  • 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: Jack doesn't actually like getting into fights, but don't push him into one. If he sees no other way out, he might as well just kick your ass.
    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 Swordsman: While Jack is talented at many things, nothing compares to his swordsmanship, with which he can slice through bullets with ease.
  • Mighty Whitey: He traveled all around the world, both in the past and the future, everywhere from England to Africa, and trained with all different kinds of warriors and mastered their styles.
  • Moses in the Bulrushes: 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!
  • The Musketeer: 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. While he doesn't use firearms in the original series, this changes in Season Five due to having lived in the future long enough to become accustomed to them.
  • 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, inspired by a group of bikers who called him "Jack" the same way one would call someone "dude" or "pal".
  • Odd Friendship: The Scotsman is pretty much his closest friend. They're about as different as they come.
  • Older Than They Look: As of Season 5, he should be in his seventies at the very least, but hasn't physically aged due to a side effect of traveling through time.
  • One-Man Army: In the series premiere 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.
  • O.O.C. Is Serious Business: Jack generally favors weapons and equipment that existed during his time period, preferring to avoid more modern tools like guns and motorized vehicles. Season 5 promotional material depicts him as using guns, bombs, and even a motorcycle. It's a pretty good indicator of just how BAD things have gotten.
  • Papa Wolf: In the (initial) final episode of the series, "Jack and the Baby", he bonds with the titular baby after saving him from hungry monsters and finding his mother. When they meet those same monsters again, he personally ensures they won't harm the boy anymore.
  • Perpetual Frowner: If he smiles (or even diverts from his usual grim expression) something unexpected is about to happen. Of course, he rarely has much to smile about.
  • 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 calm, stoic blue to the Scotman's boisterous red.
  • Samurai: Technically, Jack is a "ronin", as he is a Samurai with no liege.
  • 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.
  • The Silent Bob: Jack rarely has much dialogue, and many episodes show him going through long scenes without talking at all. More often than not, his actions speak far louder. This is very much in contrast with his enemy; Aku never shuts up.
  • 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).
  • Spoiled Sweet: Jack is very noble in both senses of the word, being an aristocrat by birth, and also a heroic man with high morals.
  • The Stoic: Most of the time when he's travelling around and nothing noticeable or sight-interesting things going around him. (Surprisingly, one person has managed to make him lose his temper real quick. Unsurprisingly, said person was the Scotsman.)
  • 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.
  • Strong Family Resemblance: As an adult, Jack looks near identical to his father.
  • 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.)
  • Super Reflexes: When Jack goes to the Three Blind Archers' tower, his first step causes them to deliver an arrow that lands between his forward foot's big toe and the one next to it while he spreads them out. He takes another step and proves that wasn't luck with reacting to spread his toes out on his other foot to avoid the next three arrows that are fired at him. This is just a taste of his lightning-quick reflexes - naturally, he's also capable of deflecting or slashing high-velocity projectiles traveling through the air.
  • The Teetotaler: Every time he enters a bar or a canteen, he orders tea or water (sometimes used to make tea).
  • Throwing Your Sword Always Works: It's come up in a couple of desperate situations.
  • Took a Level in Cynic: In Season 5, due to spending 50+ years unsuccessfully trying to escape a Bad Future.
    Jack: There's no way home! There's nothing to fight for!
  • True Companions: Jack is determined to get back to his own time period as soon as he can, but he'll apparently make time when it comes to the Scotsman, such as when he agreed to a number of competitions with him for the privilege of rowing the boat off the island. The fact Jack humored his challenges without complaint and was uncharacteristically smug about it the entire time just goes to show how close he really is to him. Jack even grips his sword once the Scotsman starts arguing, knowing that a competition is brewing (although the challenges ironically did not involve swords).
  • 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.
  • World's Best Warrior: The number of enemies who can genuinely match him one on one can be listed on one hand. The Guardian is one of the few who is his superior one on one, but the time portal implies Jack is destined to one day surpass him. If nothing else can be said, Aku has outright stated there doesn't exist a fighting style superior to his, thus why he made Mad Jack.

Main Antagonist

Voiced by: Mako, Greg Baldwin (Fusionfall, Season 5), Fred Tatasciore (Punch Time Explosion)

Long ago - very long ago - a single small fragment of an 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: Aku is very weak to divine magic as his Made of Evil physiology can be burnt apart easily by the magic. The formless evil that spawned him was slain by a trio of Gods who later imbued Jack's sword with the same energies allowing it to harm Aku. Aku can No Sell just about anything else unless it's of divine origin and even episodes like "Jack and the Gangsters" shows Aku being defeated by a water goddess and her minions.
  • The Ageless: Immortal. That's pretty straightforward.
  • Arch-Nemesis: To Jack.
  • Attack of the 50-Foot Whatever: And he is only a fragment of what he came from.
  • Back from the Dead: The first thing he did when he came back to life in the premier was to attack the town, and Take Over the World.
  • Badass 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?
  • Bad Boss: You're probably safer as one of his victims than one of his minions.
  • Beware the Silly Ones: Aku is a lovable goofball... 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, even when he has nothing to gain 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's Fairy 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 may not have a problem with lying to them or brainwashing them, but he thinks hurting a child is actually going too far, despite the fact he could get away with it at any time, and that they tend to make a joke out of him.
  • Evil Cannot Comprehend Good: Given that Aku is the Anthropomorphic Personification of evil, it's only natural that he suffers from this trope. Many of Aku's schemes fail because he has no understanding of the concept of good.
    • This trope is why him sending Jack to 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 resisting him would trigger Hope Springs Eternal and start giving the oppressed masses someone to rally behind.
    • Also shows in the episode "Aku's Fairy Tales" when, out of a desire to be admired, he tries to make himself out as the good guy in the stories he tells to children... and one of the prime reasons it doesn't work is that he can't really comprehend what "good" means — the closest he can come to understanding heroism is "free beef jerky for all"!
    • In the episode "Jack vs the Imakandi", Aku hires the titular Imakandi to hunt down and capture Jack, promising them a handsome reward if they're successful. However, what he failed to take into account (and what they outright tell him), is that they hunt not for wealth, but for the thrill of the hunt. So when the finally capture Jack, he's given them such a challenge that they choose to set Jack free rather than deliver him to Aku. Aku does not take it well when they break off their deal.
  • 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. He clearly isn't a dimwit - he did subjugate the Earth - but he's prone to errors in judgement.
  • Evil Is Bigger: Much bigger, but mostly because he prefers to be big as his standard form.
  • 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 makes 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.
  • Hero Killer: In "Birth Of Evil", he slaughtered most of the warriors serving under Jack's Father. It is also quite likely that Jack's Father later died as an old slave, deprived of water under Aku's reign. He's also defeated a multitude of other heroes during his reign, with a few being directly shown.
  • 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 manner 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 he does, and then tests the robots out by having them burn his village to the ground and kill everything in it.
  • 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.
  • Knight of Cerebus: A Zigzagged example. In some episodes, such as the Pilot episode and the "Birth of Evil" two-parter, he's every bit the embodiment of evil he claims to be. In other episodes, he's a complete clown with some hilarious lines. Basically, depending on the episode, he can make you laugh or scream. Sometimes both in the same episode.
  • 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. His manner of speaking (as demonstrated by the opening intro) is also based on traditional Japanese Kabuki, which comes across as hammy when translated into English.
  • 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 a threatening figure. Or sometimes a bit of both.
  • Likable Villain: He's a pretty funny guy, whenever he isn't performing any genocide, slavery, or 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.
  • No-Nonsense Nemesis: Despite his Stupid Evil tendencies, Aku has displayed this on occasion.
    • In the pilot episode, immediately after breaking free from his imprisonment, Aku's first order of business is to attack the village, massacring everyone. When Jack's father tries to get the sword, Aku immediately grabs him.
    • In "Jack and the Zombies", once Aku gets Jack's sword, he wastes no time in attacking Jack, immediately going on the offensive and forcing Jack on the defensive throughout the episode. He doesn't stop to gloat or banter and gives Jack little time to breathe.
  • Obviously Evil: Right down to his name!
  • One-Man Army: Aku has destroyed countless armies all by himself. Nowadays though, he's grown lazy enough that he relies on robots to do the conquering for him, and hires bounty hunters for other dirty work.
  • 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.
  • Our Demons Are Different: He acts a lot like Satan. He's a demon overlord, who in the future turned the world into a post-apocalyptic wasteland, and lives in a hellish underworld (the Pit of Hate).
  • 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.
  • Phlebotinum Killed the Dinosaurs: He, or rather his original mindless form, was the comet that wiped out the dinosaurs.
  • Playing with Fire: Can toss blue fireballs at opponents.
  • Really 700 Years Old: Aku (as a sapient being) has existed for centuries or even millenia.
  • 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: 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: He usually appears as a tall, shadow-like being with a green face, fangs, spikes protruding from both sides of his head, as well as eyebrows and a goatee of flame. Due to his origin it's hard to say if he's Type A (this is his true form) or Type B (it's the form he prefers to take on when not using his shape-changing abilities to fight or disguise himself).
  • 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.
    • He does get his comeuppance in regards to this at times. One example being his deal with the Imakandi, and his Hermit disguise.
    • Even his minions are prone to this, although this is a given when he orders them up like a normal person would order for take out.
  • 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.
  • This Cannot Be!: Had this reaction when Jack's father showed up with the sword and actually hurt him with it.
  • 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's Fairy 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.
  • When Trees Attack: Is a tree that was possessed by an evil entity that landed on Earth. When Aku moves, often the sound of wood creaking can be heard.
  • 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 teleported to the Pit of Hate (where he would be brainwashed until he learns to "love Aku"). 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. Although considering that Aku's favorite hobby seems to be destroying entire cities and towns, indiscriminately massacring their inhabitants, and enslaving the survivors to a life of hard labor, it would actually be quite likely that many children have been harmed or suffered under his reign.
  • You Have Failed Me: His response to Demongo's defeat is to destroy him. He even says the trope name word for word.
  • Your Size May Vary: Possibly justified as given his shapeshifting, but even then his size 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 Martin

One 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.
  • Big Damn Heroes: When she saved Jack.
  • Establishing Character Moment: Introduced herself by saving 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, who thinks it was the robots, is "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, aware of the trickery. Then, a mouse eats food from Jack's hand, but is scared of Ikra and digs underground to run away. When the jewel tests Jack and Ikra's hearts, it found out that Ikra is pure evil. The guardian mainly tries to fire its blasts at Ikra (besides Jack not wanting to fight). Near the end, Ikra can fly and become a giant to defeat the jewel guardian. There's also the fact that her color scheme matches Aku's almost exactly.
  • Obviously Evil: Her color scheme: black, green, and reddish-orange should've been a dead give away.

The Hermit

Voiced by: Mako

Another one of Aku's aliases where he wants Jack to find the Gems of Cronus so that he can revive the Titan.

The Black Mass

Only appearing in "The Birth of Evil, Part 1", 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 circa 65,000,000 BC. This is the original incarnation of Aku.

Recurring Characters

    The Scotsman
Voiced by: John DiMaggio

A 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.
  • Acrofatic: Despite being twice Jack's size, he can easily match the samurai's speed. The two of them fought to a standstill... after three days.
  • Amazon Chaser: Implied. He beams with pride when he sees his wife go One Woman Army on their enemies.
  • 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 Grandpa: He's still alive as of Season 5 and unlike Jack he's not only physically aged (putting him in his seventies at the very least) but is now wheelchair-bound. He's still no less calm however.
  • Badass Mustache: A contrast with the clean-faced Jack.
  • Beware the Silly Ones: When he's in a good mood, he's a goofy and over-excited guy, but do not hurt Jack, his best friend. You will die.
  • 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.
  • Character Development: He initially started off as a barbaric madman who challenged Jack to a fight, because they were arguing over who should cross the bridge first, and forced him into a fight. However, after working together with him, the Scotsman shows a more friendly side, and is afterwards one of the more lovable characters... as long as he's in the right mood, that is.
  • 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, holds his ground for three days, and is second only to Jack on Aku's hit list.
  • Curb-Stomp Battle: When his opponent isn't Jack, the fight is guaranteed to end quickly.
  • Cyborg: Further upgrades himself along this route in 50 years to keep fighting despite his age.
  • 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. Ironically, he's quick to criticize the Sirens' singing.
  • Empowered Badass Normal: While he is very much Jack's equal in strength and skill, he had an advantage with his machine gun leg that can also launch grenades. Furthermore, his claymore is able to stand up to Jack's divinely-crafted katana, due to possessing similar enchantments.
    Scotsman: MAGIC RUNES, LADDIE!
  • Everything's Louder with Bagpipes: His Establishing Character Moment.
    The Scotsman: By th' look on ye face I can tell ya like th' pipes, wee laddie!
  • Fat Bastard: He looks overweight, and is introduced as being very rude and temperamental. But he proves to be a Jerk with a Heart of Gold.
  • Fire-Forged Friends: With Jack, whom he refers to as a brother.
  • Flowery Insult: Gives one to Jack in their first encounter.
  • Force and Finesse: The Force to Jack's Finesse. While both are Master Swordsmen, Jack is the faster, more skilled, and cunning of the two, while the Scotsman is stronger, tougher, and better with modern weaponry.
  • 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.
  • Gosh Darnit To Heck: Swears like a sailor. Since this is a kid's show, though, he never uses any actual swears, instead relying on Flowery Insults.
  • Handicapped Badass: He's missing his left leg, but it doesn't slow him down. In fact, he's got a fully-functional machine gun as a prosthesis! The time skip has him now using a motorized wheelchair and upgrading to a minigun leg!
  • Happily Married: Inexplicable, but true! This is probably the reason why he wasn't affected by the Sirens' song.
  • 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.
  • Hero of Another Story: Aku wants to catch this guy almost as badly as he wants to catch Jack, suggesting that he's accomplished some pretty impressive feats offscreen. In the occasions where he teams up with Jack, though, there's no indication that he's done anything worthy of attracting Aku's attention. Considering his strength, it's hardly surprising.
  • Hot-Blooded: He's one of the wildest characters on the show, and is prone to shouting at the top of his lungs.
  • 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 the future, and is also his polar opposite.
  • 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, especially after being upgraded to a minigun.
  • Lightning Bruiser: He's an Acrofatic heavy hitter.
  • Like Cannot Cut Like: Jack's sword fails to break his thanks to it having similar magical properties.
  • Made of Iron: Two 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, with their first duel ending because both men were too exhausted to continue (after fighting nonstop for 3 days).
  • 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" (he does in "The Scotsman Saves Jack" though).
  • 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 and considers what could be the Most Annoying Sound as beauty to his ears.
    • When a couple of robot alligators bite his arms, he chortles, "Is that the best ye can do!?"
    • In his first encounter with Jack, Jack performs his iconic jump slash technique against the Scotsman and is baffled when the attack doesn't destroy his sword.
    • In his second appearance he's set on fire by an exploding bar. He's more concerned with finishing his sentence than putting out the fire on his face.
  • 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!
  • Proud Warrior Race Guys: The Scotsman's clan are also all a bunch of big, strong, and hot-headed warriors. Oddly, the Scotsman describes himself as being more mellow compared to his fellow clansmen.
  • 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.
  • Stout Strength: He's very wide and has torn apart tanks, smashed buildings, etc.
  • Took a Level in Kindness: After becoming friends with Jack.
  • Tranquil Fury: The one time his boisterous nature is broken is when Jack wordlessly runs his sword through the Scotsman's bagpipes. He very coldly states, "You've done it now," before beginning the fight in earnest.
  • 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, shrugging off any attacks that hit him. He's still very skilled, mind you, he just prefers to use no strategy when fighting.
  • Violent Glaswegian: He's a Scotsman and he's very loud and boisterous.
  • Walking the Earth: Similar to Jack, he mentions in his second appearance that he spends most of his time away from home because the rest of his clan are more boisterous and loud than he is, and he enjoys the solitude.
  • What Does He See in Her?: The Scotsman's wife is anything but beautiful, well-mannered, or the type of girl most men would want, yet he fell in love with her. To be fair, the Scotsman is hardly beautiful, well-mannered, or the type of guy most women would want either.
  • Worthy Opponent: He's Jack's. The feeling is mutual.
  • Would Hit a Girl: Or would shoot them with a machine gun and blast them with grenades. Granted, these women were really demonic sirens who would kidnap and enslave men.

    Jack's Father
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.
  • Action Dad: Sort of. Jack is born right after he defeats Aku.
  • Annoying Arrows: Clearly disregards having been struck by some arrows during his fight with Aku.
  • Badass Mustache: He has a moustache.
  • 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.
  • Create Your Own Villain: Sort of, in an accidental case. The black blob monster he was fighting was already very malevolent, but his attempt at destroying it instead turned it into a sapient evil-doer.
  • 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 ancient Japan.
  • A Father to His Men: When his pregnant wife tried to discourage him from fighting Aku, noting that he has a family, he replies that he regards all his subjects to be like his children.
  • How the Mighty Have Fallen: By the time Jack returns in the first episode, Aku's despotic rule has reduced him to a thin, decrepit old man, a far cry from the Cool Old Guy emperor he once was.
  • Katanas Are Just Better: Of course the only reason this one is better is because it's forged by the gods from his righteousness.
  • Lantern Jaw of Justice: Apparently it's hereditary.
  • Made a Slave: He suffered this fate along with most of his surviving countrymen under Aku's reign.
  • Nice Guy: Like his son, he is very kind and open to people and innocents.
  • 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 and defeat 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.

    Jack's Mother
Voiced by: Lauren Tom

The 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.

    African Chief

The leader of an African tribe that Jack can be briefly seen training with in the Pilot Movie during the montage of Jack growing older and learning different combat techniques around the world. The encounter was later expanded upon in the episode "Young Jack in Africa".
  • Badass Beard: He has a white beard.
  • Badass Grandpa: His white beard indicates his age. But he's as skilled and nimble as wild beasts he imitates in his fighting style.
  • Bald Black Leader Guy: He's bald and he's the leader of a tribe.
  • Curb-Stomp Battle: He and his village were defeated by a rival village quite easily at first. When Jack frees them at the episodes end, the Chief quickly saves Jack and easily trounces the rival chief.
  • Posthumous Character: Since Jack was trained by him before his eventual first battle with Aku, he's obviously long dead by the series' present time.
  • Simple Staff: His weapon of choice.

    Odin, Ra, and Vishnu
From left to right: Ra, Odin, and Vishnu
Odin voiced by: Richard McGonagle
Ra voiced by: Daran Norris
Vishnu voiced by: Daran Norris

The 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, and they crafted his sword.
  • Crossover Cosmology: Odin, Ra, and Vishnu are deities from different religions.
  • Curbstomp Battle: Ra delivers one to the Minions of Set.
  • Our Gods Are Greater: Possibly more powerful than Aku (after all, they destroyed the original Black Mass).
  • 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.

Other Characters

    Homeslice, Cole Lampkin, and Brobot
Homeslice voiced by: Phil LaMarr
Cole Lampkin voiced by: Rob Paulsen
Brobot voiced by: Kevin Michael Richardson

Three punks Jack encounters shortly after he first enters the future. They address him as "jack", which later inspires the samurai to adopt Jack as an alias.
  • All There in the Script: Their names are only shown in the end credits.
  • Amazing Technicolor Population: Homeslice is magenta, Cole Lampkin is pale green, and Brobot is blue.
  • Ambiguously Human: As humans of natural skin color appear in the series, it's not known if they're humans or aliens that look human.
  • Jive Turkey: In addition to calling the samurai "jack", their dialogue is just filled with urban slang.
  • Small Role, Big Impact: They only get one scene, but are the reason the show's main character goes by "Jack". They also explain to Jack that Aku has taken over the world in his absence.

    The Canine Archaeologists
Rothchild III voiced by: Rob Paulsen
McDuffy and Dreyfuss voiced by: Jeff Bennett

Three 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).
  • Civilized Animals: They're descended from dogs that somehow evolved to become sapient.
  • My Instincts Are Showing: Despite being well-mannered and British, they are still dogs, and enjoy sticking their heads out of the window of their flying car while driving.
  • Mr. Exposition: The dogs tell a summary of future history to Jack, saying that after Aku conquered the whole planet, he expanded his empire across the galaxy; which would explain the dystopian metropolis filled with flying cars, and inhabited by aliens and other non-humans.
  • Nice Guys: They're all very friendly, helpful and polite.
  • Non Action Guys: 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.

    Beetle Drones 

The standard Aku mooks in the series. The Beetle Drones are a hoard of large robotic insects who's claws double as scythes. A recurring army of antagonists, they appear in all seasons and even return in Season 5 with an upgrade.
  • Defeat Equals Explosion: Nearly all the time.
  • Mooks: The most conventional example in the series. They're numerous, aggressive, and easy to kill to make Jack look cool.
  • Red Eyes, Take Warning: The redesign in Season 5 has the Beetles sporting red optics curved into a permanent glare rather than the wide blue optics of the previous model.
  • Red and Black and Evil All Over: Much like Aku's color-scheme, the Drones all have prominent red and black coloring to them. The Season 5 bots even drop the blue eyes and keep the color-scheme entirely red and black.
  • Replacement Mooks: In-Universe, the Beetle Drones surprisingly got a bit of backstory in "Tales of X9" as they were the replacements of the X-Series of robots constructed by Aku's human scientists.
  • Zerg Rush: Their only semi-competent tactic is to swarm their enemies. This was especially evident in the pilot which featured the most amount of onscreen Drones in the entire series.

    The Woolies 
Voiced by: Kevin Michael Richardson, Brock Peters (Woolie Elder)

A 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 forced the Woolies into walking like animals and prevented 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.

    The Chritchellites 
Voiced by: Tom Kenny

A race of diminutive conquerors who enslaved the Woolies and took over their civilization, claiming it as their own.
  • 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: Their 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.
  • A Nazi by Any Other Name: Enslavers of Space Jews.
  • 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 Astronauts 
Frederick and Sergei voiced by: Jeff Bennett
Technician voiced by: Jennifer Hale
Idealist and Analyst voiced by: Tom Kenny

A 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.
  • All There in the Script: They are not named on-screen and their designations are only given in their episode's end credits.
  • Doomed Contrarian: Subverted. While one middle-aged astronaut argues against the younger astronauts that there is no point in continuing on, he does improve his attitude later, and even survives.
  • 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 Archers 

Three 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.
  • One-Man Army: Well, three of them, but nonetheless the first showing of their handiwork shows them filling the sky with arrows from their tower and obliterating a robot army (that also look like vikings) in the space of a very explode-y minute.
  • Super Senses: 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.
  • Visual Pun: Why do the archers have large upraised ears and a very long nose jutting out of their face like some kind of rodent while they were enslaved to the well? No doubt because of the nursery rhyme the Three Blind Mice.

    Mad Jack
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.

    The Triseraquins 
Connery voiced by: Jeff Bennett
Guiness voiced by: Mark Hamill
Ringo voiced by: Jess Harnell

An alien tribe who live in a floating city. Their city is menaced by Aku, who demands a simple price for sparing them...
  • All There in the Script: They are only named in the episode's end credits.
  • Atlantis Is Boring: At least, until Aku showed up.
  • Crazy-Prepared: They have an army at the ready in the event that Aku betrays them. It doesn't work.
  • Easily Forgiven: Jack doesn't hold anything against them, knowing that Aku can manipulate anyone with a deal just too good to pass up.
  • Et Tu, Brute?: They aren't inclined toward villainy, but they're being blackmailed.
  • Horrible Judge of Character: Jack points this out to them that Aku cannot be trusted. Unfortunately, this is justified due to Aku's power keeping their city under water, and thus he is the only one who can lift it. Predictably, he doesn't.
  • No Celebrities Were Harmed: Their names and voices are most likely references to UK celebrities Sean Connery, Alec Guinness, and Ringo Starr.

    The Lava Monster 
Voiced by: Richard McGonagle

A 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 is to die in battle so that he can be free of Aku's curse. Jack grants it to him.
  • Easily Forgiven: Once Jack learns his backstory, he quickly forgives him for all the warriors he killed.
  • Forced to Watch: Rather than killing him, Aku burned his kingdom to the ground. That was before cursing him.
  • Proud Warrior Race Guy: Dying in battle is the only true death for 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 one as he dies.
  • Worthy Opponent: Sets up a Death Course to find one strong and skilled enough to beat him.

    The Gangsters 
Boss voiced by: Maurice LaMarche
Mr. Pibbles voiced by: Larry Cedar
Mr. Shine and Knuckles voiced by: Kevin Michael Richardson
Stitches voiced by: Andre Sogliuzzo

A 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.
  • Expy:
    • The gangster's boss, "Don", is clearly based on gangster characters played by actor Edward G. Robinson: not only do they look alike, but they also share the same verbal tic (peppering their speech with heavily accented "yeah!" and "see?" for emphasis).
    • The entire gang is clearly based on the Ant Hill Mob from The Perils of Penelope Pitstop and Wacky Races.
  • 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.
  • Heel–Face Door-Slam: They offer to return the magical water jewel they previously ordered Jack to steal to prove that they turned a new leaf. Jack accepts, but as soon as he walks away, they decide to monopolize on the city's water supply. At least they decided to stop blowing up animal shelters.
  • 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.)
  • I Owe You My Life: Jack interrupts an assassination attempt on them, earning their respect and a position in their gang.
  • Karma Houdini: They lie to Jack about going straight and having the Neptune Jewel returned to its proper place and are last seen using the Neptune Jewel for their own ends.
  • Kick the Dog: They ordered Jack to deliver a package to the owner of an animal shelter. Thankfully, Jack averts this by warning the owner and getting him to flee before the package goes off.
  • The Mafia: Played for laughs.

    The Goddess of Water and the Elementals 
Fire Creature voiced by: Grey DeLisle

A 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.

    The Children 
Voiced by: Anndi McAfee, Gary Leroi Gray, and Josh Peck

Kids that are fans of Samurai Jack and are part of Aku's fairy tales.
  • Audience Surrogate: They tell Aku what the audience is thinking, particularly when they start to pick at the flaws in his stories.
  • Children Are Innocent: Aku attempts to exploit this to garner sympathy and respect from the children.
  • Hero Worship: The kids love Jack to the point that they (reluctantly but bravely) request Aku to speak of stories related to Jack, much to his shock.

Monkey Man voiced by: Jeff Bennett

A tribe of round little white-furred apes (and a wild man who lives alongside them).
  • Actual Pacifist: Until Jack trains them; then they become Martial Pacifists.
  • All There in the Script: The Monkey Man isn't named onscreen.
  • 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 Worm 
Voiced by: Tim Curry and Phil LaMarr

A magical two headed worm who is said to be able to grant the wish of anyone who can guess its riddle.

    The Metal Eating Family 
Woman voiced by: Jennifer Hale

A family of lost travelers, consisting of an average woman, a huge male, a short and elderly woman, and a young boy. They are actually metal eating robots.
  • Bitch in Sheep's Clothing: They were nice to Jack at first. Then they start to get violent and try to eat his blade.
  • Monstrous Cannibalism: Their ultimate fate once they discover what they each are really made of is that they eat one another. It's as disturbing as it sounds.
  • Tomato in the Mirror: The family are robots, but don't seem to be aware of it.

    The Gargoyle 
Voiced by: Jeff Bennett

A brutish gargoyle who seals a magical fairy inside an unbreakable sphere, intending to force her to grant his wish.

    The Wishing Fairy 
Voiced by: Jennifer Hale

  • Benevolent Genie: With a rather major drawback - only one wish, ever.
  • Damsel in Distress: Her tale starts when she's somehow captured by the gargoyle.
  • Taking A Third Option: Unable to break from her prison, and Jack's hand being stuck, Jack opts to wish for their freedom instead.

    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 Richardson

Nine 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: he's ticklish.
  • Wolverine Claws: The Claw's signature weapons.

    The Scotsman's Wife
Voiced by: Ruth Williamson

A woman married to the Scotsman, who was once kidnapped by an army of demonic robots. She's not so much a "skilled fighter", but more of an elemental force of raw destruction (and insults).
  • Action Girl: When properly enraged.
  • Badass Damsel out of Distress: She had to be rescued by Jack and the Scotsman, but was somehow still capable of destroying the same army that captured her and were about to defeat the two men. Why she couldn't (or wouldn't) save herself earlier is anyone's guess, but it was likely due to the Rule of Funny.
  • Badass Normal: She may not have any powers herself, but she's not afraid to fight anyone who's powerful.
  • Berserk Button: Refer to her size and you perish.
  • Bruiser with a Soft Center: While she can be unbelievably powerful and so destructive that she makes a hurricane look like a bad drizzle, in better circumstances she's very nice and dearly loves her husband (and she's not afraid to show it).
  • Complaining About Rescues They Don't Like: Might as well be the poster child for the trope. When her husband comes along with Jack to rescue her from the Celtic demons, all she does is nag, complain, and whine about every little thing they do. As a bonus, she does it so loudly, that any hope Jack and the Scotsman had of escaping via stealth is dashed, they are captured by the Celtic demon swarm, and had the lead Celtic demon not made the mistake of calling her "fat," Jack and the Scotsman, who were being worn down by a massive Zerg Rush would have been killed, and she would have been "sacrificed."
  • Deadpan Snarker: She throws around sarcasm and sardonicism like no tomorrow.
  • Eye Scream: Pokes several of the demons' eyes out.
  • Fat Bitch: She's fatter than her husband, and has an even worse temper. Just don't ever mention her weight in front of her.
  • Fiery Redhead: Stereotypical Scottish temper.
  • Flowery Insults: Even more skilled than her husband!
  • Gonk: She's so obese and unattractive, that only a a man like her husband can call her beautiful. But 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 her own husband is afraid of just the thought of angering her, and her husband is The Scotsman, who is usually willing to stand up to anyone.
  • Happily Married: Rarely shows it, but it's there. But we'll never understand it.
  • Informed Ability: According to her husband — who is hardly an impartial judge — she sings "like an angel". Her voice isn't actually pleasant though. Then again, considering what the Scotsman's idea of a "beautiful voice" is...
  • Insistent Terminology: "I am not fat! I'm stout!"
  • Jerk with a Heart of Gold: She's a stereotypically bitchy and nagging housewife, but still loves her husband. She also warms up to Jack, at least until he comments about her size.
  • One Woman Army: Defeated the whole drone army which 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.
  • Stout Super Strength: She's a powerhouse much like her husband.
  • Tsundere: An interesting Western version of this. While irritated, she's even ruder and louder than her husband. When angry, PRAY TO GOD she gives you a quick death. However in more pleasant circumstances, she's cheerful, kind and polite.
  • Unstoppable Rage: Destroys the entire demon army holding her captive with her bare hands (and feet, and teeth, and forehead...)

    The Celtic Demons 
Voiced by: Phil LaMarr and Jeff Bennett

A 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.

    The Ultra-Robots

Eight nigh-invulnerable killing machines that are design by Extor as a means to kill Jack. Aku then empowers them and test by destroying Extor'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.
  • Curb-Stomp Battle: Deal one to Jack in their first fight thanks to his sword being unable to cut through them. When he gets the Power Fist from Extor he fights them on more equal terms until it runs out of power, though until Jack gets his divine intervention he's unable to even land a single blow on the last one.
  • Famous Last Words: The lead bot can only think of one word when Jack cleaves him in half, with some divine intervention.
    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 Jack's.
  • Magitek: Their power source is actually Aku's essence.
  • More Dakka: The robots that uses projectiles for weapons uses this style of attack.
  • No Sell: Extor worked long and hard to make them a match for Jack, and as such his initial attacks aren't able to phase them. Despite the superior power of his sword, they were made of adamantium, which meant that Jack lacked the raw strength to cut them. Extor evens this out by giving him a power gauntlet that augments his strength to where he is able to slice through the robots. When the power for the arm runs out, Jack summons the power of his ancestors and of the spirits to give him a boost to destroy the last robot.
  • Red Eyes, Take Warning: They have red eyes and they are very dangerous.

Voiced by: Jeff Bennett

The creator of the Ultra-Robots designed to kill Jack, he made them as part of a deal with Aku in order for his home to be spared. Predictably, Aku betrays him by sending his creations to destroy his village. He seeks to redeem himself by helping Jack destory his creations, namely evening out the odds via a power gauntlet.

    The Three Monks 
Monk #1 voiced by: Corey Burton
Monk #2 voiced by: Kevin Michael Richardson

Three 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.
  • Comically Serious: They never interact with any fiends they come across, hold the same expressions throughout the whole episode, and always press forward regardless of Jack's stake in this.
  • Heroic Second Wind: When Jack is down, the monks speak to him telepathically, testing his resolve.
  • 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?
  • Not So Stoic: They are for the most part unemotive. However at the end of the episode when they speak to him telepathically, the head Monk barks his last question with a surprising amount of conviction, asking if Jack has forgotten what his purpose is.
  • The Quiet One: They're not talkers.
  • The Stoic: They don't show much emotion.

    The Farting Dragon 
Voiced by: Clancy Brown

A 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.
  • Fartillery: Her flatulence is absolutely noxious. Every time she blows her booty the village beneath her cave nearly suffocates.
  • Gasshole: Thanks to a case of indigestion.
  • 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.

    The Imakandi 

A race of lion-headed hunters, they are considered the greatest hunters in the galaxy.


One of Aku's most powerful minions. He has the ability to summon the essences (souls) of countless warriors from his collection.
  • Asshole Victim: He's enslaved hundreds of warriors and turn them lose on Aku's enemies, so he definitely earned the beating he got when Jack released ALL of them, and when Aku killed him for his failure.
  • 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.
  • Catchphrase: "My Mastaaaah".
  • The Collector: In this case, he collects and enslaves 'essence'.
  • Curb-Stomp Battle: After Jack frees the warriors Demongo trapped, leaving him powerless, the freed warriors gang up on him, and it's implied they beat the holy hell out of him before sending him limping back to Aku.
  • Dark is Evil: Just like Aku, he's a ruthless black demon.
  • Dirty Coward: Without his enslaved warriors, Demongo is a sniveling coward who begs and pleads for his life.
  • 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 taking 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.)
  • Killed Off for Real: Is killed by Aku for failing to kill Jack.
  • Large Ham: Much like his master.
  • 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.
  • Our Demons Are Different: A demonic collector of essence.
  • 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.
  • You Have Failed Me: Aku destroys Demongo for his failure.

    The Spartans 
Brotok voiced by: Brian George
Kurtok voiced by: Danny Mann
Spartok voiced by: Daran Norris

An army of Spartan warriors protecting their secluded homeland from an unrelenting force of robotic monsters.

    The Mechanical Beast and Minotaur Robots 

An insane AI who's conquered all the lands surrounding its lair aside from the Spartan Kingdom.
  • A.I. is a Crapshoot: Possibly, the Spartan King mentions that their enemy is a mechanical beast who "went mad". 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.

Voiced by: Bob Joles

A sleazy slob who takes advantage of Jack's temporary Baleful Polymorph to climb to the top of his particular field - making animals fight to the death for the amusement of scumbags.
  • All There in the Script: His name is only shown in the end credits.
  • Bad Boss: His prize-fighting chicken doesn't receive medical care, or adequate food, or anything.
  • Fat Bastard: He's very portly and clearly not a very pleasant person.
  • It's All About Me: Carried to a comical extreme. When it looks like he's going to feed Jack, he just noshes on lasagna and continues starving Jack.
  • Just a Stupid Accent: Even when he's alone, he doesn't actually speak Italian - only broken English with a comically thick accent.
  • Karmic Transformation: He happens to bump into the same extremely cranky wizard who cursed Jack, and... well...
    Chicken with a stupid accent: Bock-a, bock-a!
  • Meaningful Name: His name comes from an Italian dish containing chicken.

    DJ Salvatore 

A rave DJ whose magical rhythm hypnotizes the children of a town Jack passes through.
  • Bald of Evil: He's completely bald.
  • Cool Shades: Wears a pair of neat-looking shades. They get destroyed after Jack beats him.
  • Dance Battler: For the first part of the battle, allowing him to match Jack blow-for-blow.
  • Evil Sounds Raspy: He has a guttural, raspy voice.
  • For the Evulz: Possibly the only reason why he has the kids raid the village is for the hell of it.
  • 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! Your 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 Father 
Olivia voiced by: Kath Soucie
Olivia's father voiced by: Michael Patrick Bell

Two of the townsfolk affected by DJ Salvatore's dance beats.
  • Brainwashed and Crazy: Olivia is mind-controlled by DJ Salvatore to become a thief.
  • Inelegant Blubbering: Olivia's father incessantly bawls over his daughter leaving him and being controlled by the DJ's music.
  • Ruritania: Their village is vaguely Bavarian.
  • Tears of Joy: Both Olivia and her father cry with joy after they reunite at the end of the episode.

    Josephine and Ezekiel Clench 
Josephine Clench voiced by: Grey DeLisle
Ezekiel Clench voiced by: John DiMaggio

A 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.
  • Distracted by the Sexy: Josephine plays this off against Jack to distract him. He doesn't bite, but his good nature does betray him.
    • She had more success with her own ex-husband, before betraying him. Again.
  • Hollywood Restraining Order: Hilariously, he took out a restraining order on her. It requires her to be no less than 150 feet from him.
  • Huge Guy, Tiny Girl: Ezekiel is taller than Josephine.
  • 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.
  • Nice Job Fixing It, Villain!: Jack's career might have ended right here had Josephine's greed not caused her to double-cross Zeke; he was able to escape and get rid of them by taking advantage of how she shoved Zeke off the train.
  • Noodle Incident: It's never said just what caused them to break up in the first place, but Josephine's actions at the end give the viewers something of an idea.
  • Parasol of Pain: Josephine uses one, its barbed ends used to restrain a victim, and a grapple concealed within to hook one.
  • Playing Card Motifs: Zeke has this. His jacket is covered with clubs, diamonds, spades, and hearts, the spurs on his boots are shaped like spades, he has a card in his hat, and of course, his cybernetic hands, the wrists of which had the playing card suits on them. The hands have a special ability depending on which suit was facing up. (He changes the setting by turning the wrist so that the desired suit is on the back of the hand.)
  • Revolvers Are Just Better: Josephine's weapon of choice.
  • Ugly Guy, Hot Wife: Ezekiel's not exactly what one would call handsome, while Josephine is a complete knockout.
  • The Vamp: Josephine. She seduces Jack to try and capture him.

    Dust Zombies 
Witch Hag voiced by: B.J. Ward

An entire graveyard, resurrected en masse to take down Jack.

    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.
  • Ax-Crazy: They will immediately and ferociously attack anything they see. The only reason they didn't attack Aku appeared to be more out of gratitude than fear.
  • 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, being completely unaware of the incoming threat until it walks onto the screen, even if it is right in front of 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 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.
    • They're on the receiving end when Jack succeeds in summoning Ra. Two of them try to fight back, but can't even get close before Ra incinerates them. the third one attemps to flee, but shares the fate as the other two.
  • 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: 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.
  • Forged by the Gods: While they may be evil destructive monsters, the Minions of Set were created by a (chaotic) god. This makes them divine by nature and thus impervious to any attack or weapon unless the attack or weapon itself is divine (like when Ra showed up and barbecued them with his heat vision).
  • 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: 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.
  • Inverse Law of Utility and Lethality: Averted against the disposable robotic minions, but played straight against Jack himself. The one's with the bladed weapons can cut him but not too badly and only really giving Clothing Damage. The one with the blunt weapons just whales on Jack and his hits are the one's to visibly and fully on connect. Granted when they beat on him with their fists or slam him into things they can do damage, just nothing too bad.
  • It Can Think: They're aggressive, not stupid. They know what the scarab does and make every effort to prevent Jack from assembling it, including trying to ingest one of the pieces.
  • 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. They attack their quarry relentlessly, without any hesitation and without any second thoughts about their actions. 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 whatsoever, 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. He only manages to even hit them twice, not that his attacks actually do anything.
  • More Teeth than the Osmond Family: The Minions have huge, gaping mouths that contain multiple rows of sharp, dinosaur-like fangs.
  • 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. They also try to stop Jack from assembling the scarab needed to summon Ra, the one thing that can defeat them.
  • 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. Sooner or later, they will catch up to you.
  • Screw This, I'm Outta Here!: After two of them were destroyed by Ra, the last one tries to make a run for it. Ra doesn't let him.
  • 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.
  • Summon Bigger Fish: The only way to defeat the Minions is to summon the only being that can harm them, Ra.
  • 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 solid stone wall with enough force to leave an 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.
  • One-Man Army: Aku tests the Minions' skills by setting them against a whole battalion of his own robotic soldiers. Obviously, the Minions gain victory in a matter of seconds.
  • Un Skilled 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 Guardian

A powerful warrior that guards a time portal, waiting for 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.
  • Apologetic Attacker: Spares Jack's life and apologizes after beating him, but Jack isn't ready to use the portal just yet.
  • 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. He won't let Jack through the time portal until he's certain that he's ready.
  • 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.
  • HAHAHA–No: This is his response to Jack's request to use the time portal.
  • 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.
  • Jive Turkey: Not as extreme as Da Samurai, but the Guardian does have this general speech pattern.
  • 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 You: 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 Problem: 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.
  • You Are Not Ready: Is told this about Jack after their battle.

    The Creature 
Voiced by: Jeff Bennett

A 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 tree stumps.
  • Unstoppable Rage: Utterly mangles the robots who hurt Jack.

    Roadster Robots 
A team of 50s-themed robots who manage to get the better of Jack with a lucky shot. To their great misfortune, it happened while the Creature was still in earshot.
  • The '50s: All four robots are built to resemble 50s teenagers - greaser hairstyles, poodle skirts, beanies, etc.
  • Mook Horror Show: The Creature smashes, mangles, and in one case chews them into fragments.
  • Plot-Irrelevant Villain: Bounty hunters? A roving team of killbots? Maybe they just hate kimonos? Who knows? In any case, they don't seem to matter much to the overall story.


The 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 Demonic Spirit

A malicious spirit that trapped the souls of a Japanese family in a haunted house. Jack manages to slay the demon and free 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 soul-eating demon who initially looks like a black mass of shadows.
  • Deliberately Monochrome: Its realm is completely black and white.
  • 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, and doesn't look or act even remotely human.
  • Flaming Sword: Its preferred type of weapon.
  • 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 lets 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.
  • Lone Wolf Boss: This creature seems completely unconnected with Aku and is basically just a random Villain of the Week.
  • Make My Monster Grow: The demon grows in size whenever Jack lands a decisive hit on it.
  • Mind over Matter: Has telekinesis.
  • Non-Standard Character Design: It's drawn in a "sumi-e" style, even outside of its own realm, unlike the other, fairly simplistic characters.
  • 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? 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.
  • Our Demons Are Different: An evil, otherworldly spirit that haunted an old house.
  • 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.
  • Would Hurt a Child: It let Kuni live to use as bait to lure in more victims, but it almost certainly would have devoured her soul too eventually, and it did take her brother's soul. Plus how many other children could this demon have devoured along with any number of other victims before Kuni's family? When you consider that even Aku, who is supposed to be the Ultimate Evil doesn't kill or harm children (at least not directly), let alone steal their souls, this trait makes this demonic spirit even more terrifying.
  • Your Soul Is Mine: It feeds on souls, or at least imprisons them in a fate worse than death. And from what was shown during Jack's imprisonment, the family may have been its most recent victims.

Voiced by: Lauren Tom

A Japanese girl whose family was captured by a demonic spirit when it possessed their home.
  • The Bait: The reason the demon spared her was so that she could be used to lure more victims.
  • Blatant Lies:
    Jack: What is wrong, little girl?
    Kuni: Nothing.
  • Can't Kill You, Still Need You: The demonic spirit could have easily devoured her too like it did with her family but decided to keep her alive to use her to lure in more victims for it to devour. Given how malicious and sadistic this thing is, it could be an act of Cruel Mercy / Kick the Dog as much as it is for its main goal.
  • Children Are Innocent: She's probably the most innocent character in the series...
  • The Cutie: ... and the most adorable.
    • Break the Cutie: Her family being attacked and imprisoned by the evil spirit.
  • Damsel in Distress: Jack assumes she's this when he first encounters her, and she sure is, and her family even more so.
  • Girlish Pigtails: Her hairstyle has pigtails.
  • Rapunzel Hair: Given how short she is.
  • Traitor Shot: Lots of them; she likely knows she's luring Jack into a trap and feels guilty about it, but she's too terrified of the demon to tell Jack the truth.
  • You Gotta Have Blue Hair: Her hair is purple.

    The Shaolin Monks
Monk A voiced by: Quinton Flynn
Monk B voiced by: Matt Levin
Grandmaster Tan Zang voiced by: Peter Renaday

Practitioners 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.
  • Heroic Sacrifice: The monks aiding Jack were willing to die for him since the beginning. It's this fact that convinces Jack to choose rescuing them over entering the portal, as Jack realizes that he wasn't willing to die as they were.
  • 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.
  • Warrior Monk: Eastern variants.
  • You Shall Not Pass: The two young monks order Jack to flee back to his time line while they hold off the mooks, and would eventually fall in combat. Jack, of course, later decides against this.

    The Labyrinth Thief 
Voiced by: Rino Romano

A 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.
  • Changed My Mind, Kid: Leaves Jack for dead, trapping him with an endless supply of the labyrinth's guardians. Some exchanged blows and an exhausted samurai later, a grappling hook drops from the ceiling for Jack to escape with.
  • Enemy Mine: There are a couple of occasions where they have to cooperate against the pyramid's defenses.
  • Expy: 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 Ninja 

A robotic ninja clad in black sent by Aku to destroy Jack.

    Mondo Bot 

  • 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.

    Da Samurai 
Voiced by: David Alan Grier

A 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.
  • Bullying a Dragon: Picked a fight with Jack despite having heard about him. Even after Jack tries to simply politely ignore him, he goes out of his way to antagonize him until Jack finally agrees to a fight. Predictably, his 'fight' with Jack amounts to Jack causally blocking his attacks and humiliating him without even trying. With a piece of bamboo, considering him unworthy of an actual sword fight.
  • 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". The fight only goes on as far as it does because Jack by all accounts had him beat in two moves and decided to let him get back up.
  • Defeat Means Friendship: In this case, defeat brings humility, which brings respect.
  • Dirty Coward: Once an army of Aku's assassin's come between him and Jack, he attempted to flee, but gets restrained by one assassin's headlock for the trouble.
  • 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.
  • 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".
  • Jerk with a Heart of Gold: He's not a bad guy, and Jack seems to recognize this. By the end of the episode, he seems eager to be a better person.
  • Jive Turkey: Biiiiig time.
  • Just Toying with Them: Jack does this to him. For starters, Jack refuses to use his actual sword and chooses to use sticks of bamboo and the first two moves would've ended the 'fight' had Jack not let him up. The rest of the battle consists of Jack systematically humiliating him until he's fighting in his underwear and either blocking or doing a Nonchalant Dodge to everything he throws at him.
  • Normal Fish in a Tiny Pond: He was the strongest guy in the area that he lived in, which caused his ego to swell and make him believe that he was the strongest guy in the world. Meeting Jack and experiencing firsthand just how far from the truth that was causes him to change his ways.
  • Overshadowed by Awesome: Being a moderately skilled warrior means all of nothing in this setting. While it's able to earn him minor fame and power in a small community of noncombatants, he loses it all the second Jack enters the scene.
  • Scary Black Man: While the audience sees him as a comical character throughout his episode, he was viewed as an intimidating bully by the local populace until Jack knocked him down a peg.
  • Small Name, Big Ego: He's decently skilled, but nowhere near as much as he thinks he is. He even thinks he's strong enough to fight Jack himself and win. Jack thoroughly proves him wrong.
  • 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.

    Princess Mira and the Bounty Hunters 
Princess Mira voiced by: Grey DeLisle
Boris voiced by: Kevin Michael Richardson
Jujunga voiced by: Kevin Michael Richardson
The Gentleman voiced by: Daran Norris
I and Am voiced by: Kevin Michael Richardson

A team of bounty hunters who argue over plans to kill Jack.

  • Attack! Attack! Attack!: Boris’ first resort to any problem is to pound it to pieces.
  • 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".
  • Instrument of Murder: The bounty hunter Jujunga uses a blowgun disguised as a workable flute; he lures a victim close with his music before using it to ambush with.
  • 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.
  • Noodle Incident: When Mira reveals herself to the bounty hunters, the Gentleman asks Jujunga if "she's the one who captured... that guy on... that planet" as a way of making sure she's who she claims to be. We never get to know any more details of that incident.
  • Overshadowed by Awesome: 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.
  • Shaggy Dog Story: Their episode is devoted to them and only to them, developing their characters via their backstories, their hunting methods, and even their relationships with each other. By the time they finally confront Jack, 90% of the episode has aired. You can probably figure out the rest from there.
  • 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.

    The Sirens 
Siren #1 voiced by: Jennifer Hale
Siren #2 voiced by: Janine La Manna
Siren #3 voiced by: Tara Strong

A trio of female monsters who hypnotize people with their singing.

    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.
  • Lightworlder: Their home world has less gravity than Earth, making them seem weak on Earth. In their own environment, they are great fighters.

    The Seasons of Death 
Scientist voiced by: Dee Bradley Baker
Spring Sprite voiced by: Grey DeLisle

Opponents Jack faced during the four seasons in "The Four Seasons of Death".
  • Bald of Evil: The scientist Jack encounters during fall has a bald head.
  • Fairy Sexy: The personification of Spring is attractive, but wicked.
  • Karmic Death: The scientist tries to trick Jack into drinking poisoned water, only for Jack to feign unconsciousness so he can spit the water into the scientist's mouth, which causes him to turn into autumn leaves that blow away in the wind.
  • Secret Test of Character: Spring tempts Jack to give in to his weariness and leave the fight against Aku to others. Once Jack refuses to give in and leaves, it's made clear that Jack's decision was what she intended all along.
  • Shaggy Dog Story: In the winter, an ogre has his people craft him a sword to fight Jack with. Jack bests the ogre and breaks his sword in two the instant the fight begins.

    X 9
Voiced by: Daran Norris

A 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.
  • Anti-Villain: Type II. Depends on how you view his mission.
  • Badass in a Nice Suit: You have to admit, this robot has style. Though all of his fellow X-model robots wore the same suits.
  • 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.
  • A Boy and His X: A Robot and His Dog.
  • Even Evil Has Loved Ones: His beloved pet dog Lulu, which inspired him to stop being evil. Until Aku noticed and exploited this to force him back into service...
  • 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: Unlike the typical villains who go after Jack, he has no delusions about his chances. He knows that entire armies of robots that were built to replace the X series couldn't stop him. But he tries anyways and, Reality Ensues.
  • 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.
  • Gun Kata: Some of his gunfighting resembles this. Justified as he is a robot who could make all the necessary calculations for aiming.
  • 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: He could've easily been a Cowboy Bebop character being a former criminal who uses Guns Akimbo.
  • Hitman with a Heart: Provides the current page image!
  • Homage: X9's robot form looks very similar to the T-800 endoskeleton from 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 Man: 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.
  • Mecha-Mooks: One of numerous robotic soldiers sent to fight Samurai Jack, but X9 stands out from all the rest...
  • Morality Pet / Pet the Dog: A literal example when he adopted Lulu the dog, who certainly brought out his good side.
  • More Dakka: Of the pistol variety. Only once do we see him actually taking an 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.
  • Professional Killer: He was designed to be one. But eventually he decided that he'd rather be an amateur musician.
  • Ridiculously Human Robots: Because of the aforementioned emotion chip, X9 cared a lot about himself and his dog, which caused him to retire from the assassin life.
  • 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.
  • Too Dumb to Live: Averted thanks to his emotions, which gave him the self-preservation instincts needed to survive. The other X-robots didn't care about themselves, so they were all slaughtered.
  • Tranquil Fury: Another advantage of his emotions was that he could feel Unstoppable Rage, but still retain the calculating head of a robot.
    I got angry. It wasn't pretty.
  • Trench Coat Brigade: The last surviving member of one, anyway.
  • Verbal Tic: "Lulu... sweet thing."
  • What Measure Is a Non Human Mook?: Deconstructed very strongly. While it's made clear that most of Aku's army really are just mindless killing machines that need to be destroyed, X9 is an exception, but of course there's no way for Jack to know that until it's too late.

    Evil Chief 

The leader of a rival African tribe hired by Aku to capture Jack when he was training in Africa as a youth.
  • Agony of the Feet: Upon being freed, the African Chief that the Evil Chief held prisoner retaliates by striking his toes.
  • Posthumous Character: He lived way back in Jack's era, so of course he's long dead in the future.
  • Scary Black Man: He's an evil and fearsome warrior from the African savanna.
  • Would Hurt a Child: He and his underlings had no qualms with harming young Jack.

    The Baby 

A baby Jack rescues from being eaten by ogres, then looks after until he can return the child to his parents.
  • Badass and Baby: Jack has to deal with a robot assassin with a French accent and the same ogres that tried to eat the baby while simultaneously seeking out the baby's parents.
  • No Name Given: Even after being returned to his mother, the child's name isn't revealed.
  • Troubling Unchildlike Behavior: Jack apologizes when the boy's mother notices the big scowl on his face, explaining that "your son has seen death" and now has "the spirit of the samurai" in him.


A group of ogres who tried to eat a captured infant. They later try to get even with Jack after he rescues the baby.
  • Cyborg: They all have robotic limbs, some of which contain weaponry.
  • Eats Babies: They tried to eat a baby before Jack came to the child's rescue.
  • Fat Bastard: All of them have pretty enormous girths.

An elderly seer who resides in a scorching desert. He sent Jack on to find the Rope of Eons to return to the past.
