    Samurai Jack 
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.

  • Honor Before Reason: Which makes sense, since honor pretty much defines what a samurai is all about.
  • 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: Of course, the only reason being it was forged by the gods from his father's righteousness. It appears to be evenly matched with The Scotsman's sword, which was similarly mystically enchanted.
  • Lantern Jaw of Justice: The jaw's half the length of his face, and the man it's attached to is decisively just indeed.
  • Limited Wardrobe: Always appear to be wearing the same white kimono to start every episode off - it's even unlimited in its limited-ness, because he keeps suffering Clothing Damage!
    • Most of the money he acquires while drifting from town-to-town is probably spent on replacement kimonos.
  • Made of Iron: Doesn't matter how intense the battle is. He always comes out of it alive, even if he's significantly worse for wear.
  • Moses in the Bullrushes: As soon as Aku attacked their kingdom, his parents sent him out of the country on a lifelong training mission and was raised by various different mentors in different lands.
  • Mr. Fanservice: Oh so much. He's even got some fangirls in universe!
  • Named by Democracy: It's what the first people he talks to call him and they introduce him as Jack to their friends... then Jack is put up on his wanted posters...
  • Nice Guy: Until you do something to piss him off.
  • 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.
  • One-Man Army: In the premier he takes down a whole army of killer robots by himself and wins, and in other episodes he routinely destroys multiple opponents at once.
  • Only Known by Their Nickname: Jack's real name is never mentioned in the series, not even by his parents! When Jack tells Ikra (who, as Aku, is almost the only being in the future that could know Jack's name) that he is called Jack, her expression is priceless. Of course, had she accidentally let slip his real name, she would have blown her cover right then and there.
  • The Quiet One: Usually speaks only a few lines each episode; some episodes he never speaks at all.
  • Red Oni, Blue Oni: The blue to the Scotman's red.
  • Samurai: No kidding!
  • Samurai Ponytail: Jack fits pretty clearly into the first variation of the trope with his noble attitude.
  • Set Right What Once Went Wrong: Sums up his mission in life quite nicely.
  • 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.
  • Slipknot Ponytail: Also a magnet for this after season one (not as much as the Clothing Damage example, but it does happen).
  • The Stoic: Most of the time...
  • Strong as They Need to Be: He can consistently fight armies of enemies, but his limit varies depending on what the plot requires, along what his sword can cut through. It can hurt Aku, when almost nothing else can, and bring down giant robots, but it can almost never cut through the weapon his enemy uses.
  • 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.
  • The Wise Prince: He's actually a prince, and the day Aku appeared signaled the end of his sheltered childhood.

Voiced by: Mako, Greg Baldwin (Fusionfall), 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.

  • Big Bad: One of Jack's main goals is to defeat Aku.
  • 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, which led to tv static.
  • 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, and they were not aware that that was his doing, but he does remember them.
  • Card-Carrying Villain: Often refers to himself by several evil-sounding titles, 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 though he never stands to gain anything from it
  • Combat Tentacles: Whenever he's in octopus form (one of his favorites) or reverts to formlessness.
  • 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.
    • Immortality aside, the episode "Jack and the Gangsters" shows it is still possible to at least overpower him and keep him at bay. The episode revolves around a MacGuffin called the Jewel of Neptune, a powerful artifact that even Aku himself is unable to seize due to the powerful elemental spirits guarding it. His numerous attempts to steal it have resulted in him getting his ass handed to him (both by the jewel's creator in his first attempt and the elemental spirits in the later ones), and during the timeframe of the episode, he'd long since given up trying. Cue Jack infiltrating a group of Aku-friendly mobsters and obtaining the jewel so he can be granted the opportunity to meet Aku face-to-face.
  • Dark Is Evil: In addition to being mostly black, his primal form is nothing but a billowing dark mass.
  • Do Not Go Gentle: While his usual response to things not going his way is to run, if that's not an option, usually when confronts him in his castle, he won't go without a fight.
  • The Dreaded: He's called Aku for a reason.
  • Deadpan Snarker: Depending on his mood.
  • Eldritch Abomination: Spawned from the remains of a much larger one.
  • Evil Cannot Comprehend Good: A large reason that his attempt to throw Jack into the future backfired. He'd expected a world ruled by him would allow him to crush Jack effortlessly when he arrived. He never took into account that a hero arriving and successfully fighting back his forces would trigger Hope Springs Eternal and start giving the oppressed masses someone to rally behind. Also shows when he tries to make himself out as the good guy in the stories he tells to children in one episode, one of the prime reasons it doesn't work is he didn't really comprehend what being The Hero actually meant.
  • Evil Is Hammy: Just the way he talks is so bombastic and over the top.
  • Evil Laugh: "HAA HAA HAAAA!!"
  • Evil Overlord: Currently rules the whole planet and expanding his empire beyond.
  • Evil Plan: The first one, take over the world, was over 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."
  • 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.
  • 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 complete and utter monster who punts dogs like footballs. He would probably be the most disturbing villain in animation history if he wasn't so damn entertaining to watch.
  • Four-Fingered Hands: Considering he's great evil, there's probably a meaning to it.
  • 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.
  • Foil: He's very much the exact opposite of Jack. While Jack seeks to do good where ever possible, even at risk to his well being and goal of returning to the past, Aku always seeks out any action where he make life miserable for others.
  • Galactic Conqueror: Ruling the Earth wasn't enough, so he extended his conquest to other planets. It's not made clear how many planets he's conquered, only that it's attracted aliens of all sorts to the Earth. What has been shown of his conquests, is that he once reduced a planet unable to support its indigenous inhabitants for no apparent reason besides that he could.
  • Jerkass: Fairly obvious as he is a villain, though he 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 reveals that he dried up their planet, though he does let them stay on Earth provided they build statues every month. Another note is when he forces a scientist to build a set super robots to kill Jack under the promise of sparing his village if does, and then tests the robots out by having them burn his village to the ground and kill everything in it.
  • 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, and rather than killing him he sealed up inside a mountain.
    • A great example of this is when he mocks Jack in the end of "Jack and the Warrior Woman". Just when Jack finds an artifact, which could have sent him back in time to defeat Aku, Aku destroys it and mocks Jack for trusting him.
  • Laughably Evil: He's rather... Goofy for being the Ultimate Evil and all. Varies depending on the episode, there are some that present him as legitimately evil and threatening figure. Or sometimes a bit of both.
  • Large Ham: So hammy that one of the first things he makes his slaves do is build statues of him.
  • Made of Evil: Yeah, that about sums it up.
  • 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 is known by his real name.
  • Morphic Resonance: He always has the same black, red and green color-scheme in every form he takes.
  • Narcissist: He once said "No mortal can defeat him." right before getting his ass handed to him, asked for a group of fish people to build statues of him every month, and sees Jack as foolish for even trying to fight him.
  • Nigh Invulnerable: Demonstrated when we see stuff outside of Jack attack him. It doesn't seem to matter if it's ancient weapons or advanced technology, mundane forms of attack can't hurt him.
  • Obviously Evil: Right down to his name!
  • 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.
  • One-Man Army: He is able to take out many warriors at once.
  • 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.
  • 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: Due to his origin it's hard to say if he's Type A or Type B.
  • Sizeshifter: A natural extension of his shape-shifting ability, and in his default form he's usually gigantic. He tends to shrink whenever Jack's sword hits him, though.
  • Slasher Smile: Right as he is about to stab Jack with his own sword in "Jack and The Zombies", he sports a sadistic smile with crazy eyes.
  • Stupid Evil: He would actually have succeeded in defeating Jack many times over by now, if he could just resist throwing a Villain Ball at the most inopportune time, he abuses Mooks, double crosses bargains or just spends too much time gleefully torturing Jack when he could easily crush him in an instant, all just before the job is done. Jack's survival, and to extent, he and his sword's very existence, is owed to this happening time and time again.
    • Aku's last resort to send Jack into the future as Jack was about to off him. If Aku can open a portal in time in this situation, surely he was strong enough to do something a little more fatal than that. Sure, Jack's stuck in the future, but fact is that he is still alive.
  • Super Strength
  • Take Over the World: He already has, but apparently it's not enough.
  • Third-Person Person: When he's being especially hammy.
  • Unskilled, but Strong: He relies mostly on the fact few things can actually hurt him. One of those is Jack's sword.
  • Unusual Eyebrows: "GREAT FLAMING EYEBROWS!"
  • 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.
  • You Have Failed Me: His response to Demongo's defeat.
  • Your Size May Vary: Possibly justified as given his shapeshifting, but even then his sizes varies from shot to shot. At times he's 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.

  • Foreshadowing: There are many instances in that episode of Ikra's true identity. When the shaman senses the 'ultimate evil', his last line said to Jack, "You don't understand!" After Jack and Ikra escape from Aku's robots, the robots simply stop their chase and close their eyes with satisfaction, awaring of a trickery. Then, a mouse feeds food from Jack, the mouse is scared of Ikra and digs itself to run away. There is a height difference that Ikra is slightly taller than Jack. When the jewel tests Jack and Ikra's hearts, it found out that Ikra is pure evil. The guardian mainly tries to fire its blast to Ikra (besides Jack not wanting to fight). Near the end, Ikra can fly and becoming a giant to defeat the jewel guardian.

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 'Birth of Evil', it is the source of all evil. Before it consume the universe, three deities: Odin, Ra, and Vishnu arrive to exterminate this great evil. Before it was completely destroyed, a fragment of it escapes and landed on Earth by killing the dinosaurs. 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. One of the few characters who appears more than once in the series.

  • British Teeth: The few he has left, anyway.
  • Carpet of Virility: His head is about the only body part not covered in hair.
  • Everything's Louder With Bagpipes: His Establishing Character Moment.
  • Flowery Insult: Gives one to Jack in their first encounter.
  • Good Is Not Nice: In his case, it's downright rude.
  • Happily Married: Seems that way.
  • Hero of Another Story: A HUGE story!
  • Hollywood Tone-Deaf: His bagpipe playing is really bad. Still it comes in handy in "The Scotsman Saves Jack", when he uses it to drown out the Sirens' hypnotic song.
  • Jerk with a Heart of Gold: He absolutely adores his wife, and if Jack is in trouble he won't hesitate to help.
  • The Lancer: He's the closest thing Jack has to a best friend in this world.
  • Large Ham: He's the second most-wanted man on the planet and will brag about it endlessly.
    • And in "Jack and the Scotsman Part II", he reveals that his family is even LARGER hams than him to the point he's considered the mellow one. And he doesn't stick around at home much because of that.
  • Leg Cannon: A machine-gun! Doubles as Gatling Good.
  • Lightning Bruiser: Despite being three times the size of Jack, he can easily match the samurai's speed to the point of them ending their fight in a standstill....three days later.
  • Like Cannot Cut Like: Jack's sword fails to break his thanks to it having similar magical properties.
  • Man in a Kilt: And it's definitely not for fanservice.
  • No Name Given: In part because Jack never asked his name. (In fact, the writers didn't bother naming his wife or his clan either.) Interestingly, he never actually refers to Jack by his name either, he refers to him as "my friend" or "laddie".
  • Noodle Incident: Why the Scotsman is the second most wanted person in the world, presumably for Aku, is never said. However, it can be assumed that he similarly resists Aku's rule, and his ability to hurt Aku and power similar to Jack would support that.
  • 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 Scotman thinks their singing is horrible.
    • Also the when a couple of robot alligators bite his arms, he laughs at the attempt and smashes.
  • Red Oni, Blue Oni: The red to Jack's blue.
  • The Rival: Friendly competition pretty much defines his relationship with Jack.
  • Sickeningly Sweethearts: With his wife.
  • Super Strength: He's torn apart tanks, smashed buildings, etc.
  • Violent Glaswegian: Uh... check out everything above.

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.

  • Annoying Arrows: Clearly disregards having been struck by some arrows during his fight with Aku.
  • Badass: Not as much as Jack, but he still defeated Aku the first time.
  • Badass Mustache

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.

  • 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.
  • No Name Given: As with the rest of her family.
  • Posthumous Character: Just like the Emperor, she's dead in the present timeline.

  • Acrofatic: Despite weighing 700 tons, Sumoto can perform a vertical leap several hundred feet into the air.
  • 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.

  • 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 extendable 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 cant 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 beaten enough. It still doesn't do much to help him.
  • Wolverine Claws: The Claws signature weapons.

The Scotsman's Wife

Voiced by: Ruth Williamson

Married to the Scotsman, and is an even stronger fighter than he is.

  • Action Girl: When properly enraged.
  • Berserk Button: Do not call her fat.
  • Damsel in Distress: The least distressed damsel you can imagine, but still.
  • Eye Scream: Pokes several of the demons eyes out.
  • Fiery Redhead: Oh-HO, like you wouldn't believe.

A clan of demonic robots serving The Master Of the Hunt

The Ultra-Robots

Three monks that have trained and meditated their whole lives to climb a massive mountain, atop which there is said exists a great Truth.

The Farting Dragon

A dragon with a massive intestinal problems who's daily expulsion of gas plagues a nearby city.

The Imakandi


One of Aku's most powerful minions. He has the ability to summon the essences (souls) of countless warriors from his collection.

  • Blade on a Stick: The Samurai Warrior has one of these.
  • The Collector: In this case, its warriors souls.
  • 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.)
  • Noodle Incident: The first four warriors Demongo summons are recognized by Jack. Judging by their dialogue, he's met them before, but they have never appeared on the show prior to this.
  • Psychopathic Manchild: Demongo has shades of this.
  • 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.

"The White Rabbit"

The Spartans

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.

DJ Salvatore

A rave DJ who's magical rhythm hypnotizes the children of a town Jack passes through.

Josephine and Zeke

A pair of married but separated bounty hunters who end up teaming by necessity to take down Jack. It doesn't help much.

Dust Zombies

A graveyards worth of zombies resurrected by Aku 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 world. Incredibly strong, fast, agile and with a healing factor that makes them nearly invincible, the Minions are among the most deadly opponents Jack ever faces. Their appearance is loosely based on the Set Animal, or Sha.

  • Badass: They are the personal servants of a god, and are not of the mortal world. They are stronger, faster, more agile and fight with more brutality than any opponent before them. In some ways they are even more powerful Aku, as they do not share his weakness to the power of human righteousness, shrugging off strikes from Jack's sword like it's nothing. Jack admits they are the most powerful opponents he has ever faced up to that point.
  • 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, changing position with each other to keep their victims off-guard, performing flips and wall jumps, and even running across the tops 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. These creatures have no desire whatsoever to do battle with you. They want to kill you, and they are going to do it one way or another.
  • 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 being barely able to defend himself while running away in terror. Every encounter with them forces him to focus solely on defending himself, as their blitz-like battle tactics make them almost impossible to hit.
  • Glowing Eyes of Doom: The Minions of Set have solid blue eyes that glow more brightly whenever they become alerted or agitated during hunting.
  • Healing Factor/Nigh Invulnerable: The Minions have an incredibly powerful healing factor that immediately heals any wound, even the ones made by Jack's sword. Injuring them through any normal, mortal means is essentially impossible.
  • Implacable Man: The Minions Of Set do not stop once they set their sights on their prey. Jack is hunted down relentlessly, barely able to stop running for even for a few moments before the Minions are all over him.
  • No-Holds-Barred Beatdown: The main reason the Minions of Set are so fearsome is because they treat every battle like a No-Holds-Barred Beatdown. They fight with terrible ferocity and machine-like determination, and will not hesitate to mutilate practically helpless victims in their attempts to kill them.
  • Run or Die: Your only options when faced with immortal, unstoppable ancient Egyptian hell-beasts. And even then running only delays the inevitable.
  • Sealed Evil in a Can: Originally plagued ancient Egypt until the Pharaoh of the time summoned Ra and had them sealed away inside a stone sarcophagus. Aku releases them in the present to kill Jack.
  • Super Strength: The Minions of Set are huge and very muscular, allowing them to cut stone pillars to pieces, punch a person hard enough to send them flying through the air, and slam a person into a stone wall with enough force to leave an impression of their body in it.
  • Technicolor Fire: Each Minion has a weapon enshrouded in magical blue fire.
  • 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, and often drool and foam at the mouth while doing so.
  • Wall Crawl: The Minions are capable of running on walls and even upside down on the ceiling.

The Three Travelling Creatures

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.

  • Shout-Out: His appearance, usage of a Katana, and the way Jack is reflected in his eyes are all reminiscent of Morpheus from The Matrix.
  • Super Strength: As if his Hyperspace Arsenal wasn't enough.
  • Tennis Boss: Subverted; Jack thinks he can beat him by bouncing his missiles back at him, but he's sadly mistaken.
  • Time Abyss: The Guardian claims to have been guarding the time portal for "countless eons". The huge pile of rubble, debris, broken down giant robots, war machines and likely countless dead warriors surrounding the gate makes it obvious he has been doing this for a very long time.

The Creature

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.

  • 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 horrific transformation, growing several times larger, sprouting immense claws and a huge array of claws, turning red with mad-looking eyes, and having its daisies replaced by dead-looking treestumps.
  • Unstoppable Rage: Utterly mangles the bounty hunters who hurt Jack.


The God of Time And Space. He was defeated eons ago by his son Zeus and was chained to an abandoned planet in space, while his magical gloves and helmet were hidden on Earth.

The Demon Spirit

A malicious spirit that trap the souls of a family which sets in a haunted house. Jack manages to slay the demon and freed the family inside.

  • Knight of Cerebus: One of the beings that is treated seriously as this creature is independent from Aku's services.

The Shaolin Monks

Practitioners of the ancient art of shaolin kung fu, hidden away in an ancient temple. The clan 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.

The Labyrinth Thief

Voiced by: Rino Romano

A nameless expert thief who is aftr the same magical diamond that Jack is.

The Ninja

Mondo Bot

Da Samurai

Voiced by: David Alan Grier

A loudmouthed Mr. T expy and samurai wannabee who challenges Jack to a duel to prove he's the better fighter. Jack, of course, takes him down with no effort at all. Watching Jack fight a real threat, and his humble personality and behavior, sets Da Samurai down the path towards true enlightenment.

The Seasons of Death

Spring Sprite voiced by: Grey DeLisle


Voiced by: Daran Norris

A retired, obsolete, prototype assassin android with emotions. He was blackmailed into targeting Jack, by Aku. Aku's leverage, he had kidnapped the one thing dear in the robot's life: His precious dog LuLu....sweet thing.

  • A Boy and His X: A Robot and his Dog.
  • Anti-Villain: Type II. Depends on how you view his mission.
  • Badass in a Nice Suit: You have to admit, this robot has style!
  • Bottomless Magazines: Averted, but due to spare magazines stored in his arms with a special mechanism to reload his guns, he can reload very quickly, without even a one-second break in concentration.
  • Failure Is the Only Option: The series isn't named Robot Assassin X9... and Lulu. ...sweet thing.
  • 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 pet dog.
  • Genre Savvy: He's seen Jack's handiwork against the bug-bots and knows that he fighting him is likely hopeless, but for Lu Lu's sake he goes in anyways.
  • Glowing Mechanical Eyes
  • Guns Akimbo: To go with his mobster look.
  • Heel Realization: Because of his emotions, he came to understand how immoral Aku was and left to live in peace, and he went largely unnoticed because Aku's evil scientists replaced the X series robots with the bug-bots seen promeniently in the series.
  • Heroic Bloodshed: The bot may have been serving a greater evil purpose he was still only trying to save his dog.
  • Hitman with a Heart: Provides the current page image!
  • Homage: X9 looks a lot like the true form of the android assassin from a certain movie. Both are android assassins that are good with guns and have glowing red eyes. Bonus points since they're both considered obsolete models in their respective franchises.
  • Implacable Machine
  • 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: Due to the rest of the line of robots he was part of getting scrapped in favor of the bug-bots.
  • More Dakka: Of the pistol variety. Only once do we see him actually taking a accurate shot.
  • One Last Job: The whole plot of the episode. Aku blackmails him into doing it.
  • Personality Chip: His greatest strength and a biggest flaw.
  • Sliding Scale of Robot Intelligence: Average Joe Android. What he lacks in social skills he makes up for with musical ability and love for his dog.
  • Sugar and Ice Personality: A calculating robot with a soft spot for puppies.
  • Super Prototype: Thanks to his emotion chip. In a way it was a prototype within a prototype.
  • Trench Coat Brigade: A member of one, anyway.
  • Verbal Tic: Lulu... sweet thing.
  • What Measure Is a Non-Human?

The Baby

Odin, Ra, and Rama

Odin voiced by: Richard McGonagle

  • Big Good: They're the only thing Jack has to offer prayer to.
