[[folder:Samurai Jack]]
->Voiced by: PhilLaMarr, 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 WalkTheEarth, 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.

* AppropriatedAppellation: Calls himself Jack after some street kids refer to him as such.
%%* {{Badass}}
%%* BadassLongRobe
%%* BadassNormal
%%* BashBrothers: With The Scotsman.
* BerserkButton: Don't go hurting or manipulating the innocent in his presence.
* BewareTheNiceOnes: HOLY SHIT should you ever. He puts the lives of any innocent being he meets before his own, but getting on his bad side is a death sentence.
* BloodSplatteredWarrior: Well, it's ''[[SymbolicBlood 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.
* CelibateHero: 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.
* TheChosenOne: Unbeknownst to him, he's going to be this when he's older.
* CharlesAtlasSuperpower: All his physical feats are through training, right down to jumping to point where some mistake it for flight, picking up boulders, and surviving getting crushed by a building.
* ChronicHeroSyndrome: He might be able to get home faster if he ignored the suffering of those around him. [[WhatYouAreInTheDark 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.
* ClothingDamage: Seems to be a magnet for it after season one.
* TheComicallySerious: He does have a sense of humor and gets some witty one-liners, but these moments are few and far between.
* CompressedHair: Don't be fooled by that tiny ponytail. Once that pin's gone, you get some long, flowing locks [[{{Hammerspace}} that couldn't possibly make up that tiny ponytail]].
* ConsummateLiar: He frowns on deception, but he can be a pretty good liar when he needs to be.
* {{Determinator}}: No matter how many methods to return to the past get burned out ([[ChronicHeroSyndrome probably because he had to save someone over using it instead]]), he'll continue searching for more while doing everything he can to hinder Aku.
* TheDrifter: He doesn't stay in one place for long in his never-ending quest to return to the past.
* EvilKnockoff: Mad Jack, a being that was created from Jack's negative emotions.
%%* EmpoweredBadassNormal: When wielding his sword.
* FishOutOfTemporalWater: A resident of the distant past trapped in the distant future. He's managed to adapt pretty well, all things considered.
* FutureBadass: Shown briefly by the Guardian's time portal.
* GoodIsNotDumb: While he's not being hindered by ChronicHeroSyndrome, he's shown he can be very clever.
* HatDamage: Whenever he wears one, it's usually the first thing to go.
%%* TheHero
* HonorBeforeReason: Which makes sense, since honor pretty much defines what a samurai is all about.
%%* HumbleHero
%%* IncorruptiblePurePureness
* ImplausibleFencingPowers: Being able slice through anything comes from the sword's magic, but he also blocks gunfire on a routine basis, even at close range.
* KatanasAreJustBetter: 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.
* LanternJawOfJustice: The jaw's half the length of his face, and the man it's attached to is decisively [[ChronicHeroSyndrome just]] indeed.
* LimitedWardrobe: 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 ClothingDamage!
** Most of the money he acquires while drifting from town-to-town is probably spent on replacement kimonos.
* MadeOfIron: Doesn't matter how intense the battle is. He always comes out of it alive, even if he's significantly worse for wear.
%%* MartialPacifist
* MosesInTheBullrushes: 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.
* MrFanservice: Oh so much. [[PerverseSexualLust He's even got some fangirls in universe!]]
* NamedByDemocracy: 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...
%%* NiceGuy
* NiceHat: 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.
* NoNameGiven: "Jack" is an alias he took in the future.
* OneManArmy: 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.
* OnlyKnownByTheirNickname: Jack's real name is never mentioned in the series, not even by his parents! When Jack tells Ikra [[spoiler: (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. [[spoiler: Of course, had she accidentally let slip his ''real'' name, she would have blown her cover right then and there.]]
* TheQuietOne: Usually speaks only a few lines each episode; some episodes he never speaks at all.
* RedOniBlueOni: The blue to the Scotman's red.
%%* {{Samurai}}
* SamuraiPonytail: Jack fits pretty clearly into the first variation of the trope with his noble attitude.
* SetRightWhatOnceWentWrong: Sums up his mission in life quite nicely.
* ShirtlessScene: Not so much during the first season, increasingly as the show goes on, almost qualifies as a WalkingShirtlessScene at some points.
* SlipknotPonytail: Also a magnet for this after season one (not as much as the ClothingDamage example, but it does happen).
* TheStoic: [[NotSoStoic Most of the time...]]
* StrongAsTheyNeedToBe: 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.
%%* ThrowingYourSwordAlwaysWorks
* TykeBomb: 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 [[LawfulGood 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 OneManArmy.
%%* WarriorPrince
* TheWisePrince: 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 EldritchAbomination 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.

%%* AGodAmI
%%* AttackOftheFiftyFootWhatever
* BadBoss: You're probably safer as one of his victims than one of his minions.
* {{Badass}}: He is at strong and powerful demon who can swallow bullets.
%%* BadassBeard / BeardOfEvil
%%* BigBad
* BigBrotherIsWatching: 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.
* ButForMeItWasTuesday: 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.
* CardCarryingVillain: Often refers to himself by several evil-sounding titles, just in case you couldn't tell he was evil by looking at him.
* ChronicBackstabbingDisorder: See StupidEvil. He nearly always betrays anybody he works with, even though he never stands to gain anything from it
* CombatTentacles: Whenever he's in octopus form (one of his favorites) or reverts to formlessness.
* CompleteImmortality: 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 [[TheInfiltration infiltrating]] a group of Aku-friendly mobsters and obtaining the jewel so he can be granted the opportunity to meet Aku face-to-face.
* DarkIsEvil: In addition to being mostly black, his primal form is nothing but a billowing dark mass.
* DoNotGoGentle: 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.
* TheDreaded: He's called Aku for a reason.
* DeadpanSnarker: Depending on his mood.
%%* DystopiaJustifiesTheMeans
* EldritchAbomination: Spawned from the remains of a much larger one.
* EvilCannotComprehendGood: 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 HopeSpringsEternal 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 TheHero actually meant.
** That episode teaches us that the closest Evil can come is to comprehend ''[[ItMakesSenseInContext free beef jerky for all!]]''
%%* EvilGenius
%%* EvilGloating
* EvilIsHammy: Just the way he talks is so bombastic and over the top.
* EvilLaugh: "HAA HAA HAAAA!!"
* EvilOverlord: Currently rules the whole planet and expanding his empire beyond.
* EvilPlan: 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.
* EvilSoundsDeep: As his voice actor once said, "Evil comes from the ''belly.''"
* EyeBeams: Multiple types for multiple purposes; force blasts, ''incendiary'' force blasts, alchemy, summoning, teleportation, transformation, necromancy, and general spellcasting. Basically, whenever Aku's [[AffablyEvil feeling lazy]], he'll just use his eyes.
%%* FangsAreEvil
* FauxAffablyEvil: 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 [[LaughablyEvil he wasn't so damn entertaining to watch]].
* FourFingeredHands: Considering he's great evil, [[FourIsDeath there's probably a meaning to it]].
* ForTheEvulz: The only real explanation for his actions: Aku does what he does because the suffering of others amuses him, as demonstrated by his signature EvilLaugh.
* {{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.
* GalacticConqueror: 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 [[ForTheEvulz 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.
* KickTheDog: Really likes doing this. Outside of his need to back-stab everyone, he also once [[ForcedToWatch imprisoned a viking king in crystal and forced him to watch as he destroyed his kingdom]], [[CruelMercy 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.
* LaughablyEvil: 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 [[BewareTheSillyOnes a bit of both]].
%%* LargeAndInCharge
* LargeHam: So hammy that one of the first things he makes his slaves do is build statues of him.
* MadeOfEvil: Yeah, that about sums it up.
* MeaningfulName: 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.
* MorphicResonance: He always has the same black, red and green color-scheme in every form he takes.
%%* NamesToRunAwayFromReallyFast
* {{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.
* NighInvulnerable: 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.
* ObviouslyEvil: Right down to his ''[[BilingualBonus name]]''!
* OrcusOnHisThrone: 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 [[TakeOverTheWorld taking over the world on his own]] was going at too slow a pace for him.
* OneManArmy: He is able to take out many warriors at once.
* PaperThinDisguise: Due to MorphicResonance, it is often easy for the audience to tell that someone is just Aku in disguise. Jack is sometimes taken in; sometimes not.
* SchmuckBait: Aku distributed lots of "magic" around the world - time portals, wishing wells, secret magical or technological weapons. They're always SchmuckBait.
* SealedEvilInACan: Jack's father defeated him by sealing him away instead of killing him. The first episode shows him breaking free and taking his revenge.
* ShapeshifterDefaultForm: 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.
* SlasherSmile: 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.
%%* SmugSnake
%%* SpikesOfVillainy
* StupidEvil: He would actually have succeeded in defeating Jack many times over by now, if he could just resist throwing a VillainBall at the most inopportune time, [[KickTheDog he abuses]] {{Mooks}}, [[MistreatmentInducedBetrayal double crosses bargains]] or just spends too much time gleefully torturing Jack when [[JustShootHim 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''.
* SuperStrength
* TakeOverTheWorld: He already has, but apparently it's not enough.
* ThirdPersonPerson: When he's being especially hammy.
* UnskilledButStrong: He relies mostly on the fact few things can actually hurt him. One of those is Jack's sword.
* UnusualEyebrows: "GREAT FLAMING EYEBROWS!"
* VillainsOutShopping: 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!
* VoluntaryShapeshifting: 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.
* YouHaveFailedMe: His response to Demongo's defeat.
* YourSizeMayVary: 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.

* GrumpyOldMan: He's that cranky.

!!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.

* BiggerBad: Of the whole series.
* DarkIsEvil: The true embodiment of evil indeed.
* EldritchAbomination: It is a gigantic, formless mass.
* MonsterProgenitor: Since Aku can shape-shift, this mass at one point becomes a fully black armed creature while fighting the deities.
* PosthumousCharacter: It was already destroyed by the deities, but is reincarnated as Aku.
* UltimateEvil
* WalkingSpoiler: For what Aku originates.

[[folder:Recurring Characters]]
!!The Scotsman
->Voiced by: JohnDiMaggio

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.

* {{Badass}}: Fought Jack to a standstill.
** BadassMustache
* BagOfHolding: The pouch on his kilt fit just about anything, including his bagpipes and a hunk of gold as big as a boulder.
* BaldOfAwesome: Excepting his ponytail, which also marks him as a FieryRedhead
* BerserkButton: Do NOT screw with his bagpipes. He might turn your head into a flour-shifter!
* {{BFS}}: [[CoolSword A Claymore with magic runes.]] Not quite as cool as Jack's, but it comes close. He's rather proud of how big it is.
* BloodKnight: Unlike Jack, this guy really enjoys fighting.
* BoisterousBruiser: Contrasting with Jack yet again.
%%* BraveScot
* BritishTeeth: The few he has left, anyway.
* CarpetOfVirility: His head is about the only body part not covered in hair.
* EverythingsLouderWithBagpipes: His EstablishingCharacterMoment.
* FloweryInsult: Gives one to Jack in their first encounter.
* GoodIsNotNice: In his case, it's downright rude.
* HappilyMarried: Seems that way.
* HeroOfAnotherStory: A [[LargeHam HUGE]] story!
* HollywoodToneDeaf: 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.
* JerkWithAHeartOfGold: He absolutely adores his wife, and if Jack is in trouble he won't hesitate to help.
* TheLancer: He's the closest thing Jack has to a best friend in this world.
* LargeHam: 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.
* LegCannon: A machine-gun! Doubles as GatlingGood.
* LightningBruiser: 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.
* LikeCannotCutLike: Jack's sword fails to break his thanks to it having similar magical properties.
* ManInAKilt: And it's definitely not for fanservice.
* NoNameGiven: 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".
* NoodleIncident: 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.
* NoSell: 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 Siren}}s. 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. [[FridgeBrilliance 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.
* RedOniBlueOni: The red to Jack's blue.
* TheRival: Friendly competition pretty much defines his relationship with Jack.
* SickeninglySweethearts: With his wife.
* SuperStrength: He's torn apart tanks, smashed buildings, etc.
* ViolentGlaswegian: 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.

* AnnoyingArrows: 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.
* BadassMustache
%%* CoolOldGuy
%%* {{Determinator}}
* TheEmperor: Of Medieval Japan.
* IncorruptiblePurePureness: Check out where Jack gets it.
* KatanasAreJustBetter: Of course the only reason this one is better is because it's forged by the gods from his righteousness.
* LanternJawOfJustice: Apparently it's hereditary.
* NiceJobBreakingItHero: Nice job giving consciousness to a fragment of an EldritchAbomination.
* NoNameGiven: Much like his son.
%%* PapaWolf
* PosthumousCharacter: Except for certain episodes that take place in the past, he's long dead in the present timeline.
* ReasonableAuthorityFigure
* RoyalsWhoActuallyDoSomething: 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.

* BadassNormal: 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.
* NoNameGiven: As with the rest of her family.
* PosthumousCharacter: Just like the Emperor, she's dead in the present timeline.

[[folder:Other Characters]]

!!The Chritchellites
->Voiced by: Tom Kenny

* ShoutOut: The Astronaut in the green helmet looks very similar to George Jetson.

!!The Three Blind Archers

* BeCarefulWhatYouWishFor: The archers are actually three wanderers who wished to become the greatest of warriors to the Spirit Of the Well. The Spirit answered the wish by robbing them of their sight and their minds, and forced them to become his guards.
* HandicappedBadass: The three archers are blind, but still wipes out an entire army with no problem.

!!Mad Jack
->Voiced by: PhilLaMarr

After countless defeats of bounty hunters, Aku created a dark-version of the samurai in an attempt to finish Jack fueled by pure anger. However, Mad Jack is defeated when Jack meditate to seal him off since he did not exist as a manifest of Jack's negative emotions.

* EvilCounterpart: Take a guess.
* HairTriggerTemper: Since he was born of regular Jack losing his temper.
* JerkAss: Possesses none of Jack's nobility or manners.

!!The Triseraquins

!!The Lava Monster
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.

* DeathSeeker: But only by honorable defeat in 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''.
* DuelToTheDeath: The only way to be free of his curse is to ''lose'' one.
* IDieFree: His ultimate goal. Jack grants it to him.
** DyingAsYourself
** GoOutWithASmile
* LightningBruiser: He's a stone giant who's quick enough to keep up with Jack in a swordfight.
* WorthyOpponent: Sets up a DeathCourse to find one strong and skilled enough to beat him.

!!The Gangsters

A group of diminutive gangsters, supposedly working for Aku, that arent very good at their jobs. They carry more than a passing resemblance to the Ant Hill Mob from ThePerilsOfPenelopePitstop.

!!Goddess of Water and The Elementals

!!The Children

Kids that are fans of Samurai Jack and are part of Aku's fairy tales.

!!Monkey Man and Tribe

A tribe of white-furred apes and a wild man who lives alongside them that Jack encounters after another failed skirmish with Aku.

* CharlesAtlasSuperpower: The White Apes have an incredible ability to jump enormous distances due to a heavy training theyre put through.
* RaisedByWolves: The Monkey Man was originally part of a group of humans enslaved by Aku's forces, but was accidently 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.
* TrainingFromHell: 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.
* TrainingThePeacefulVillagers: 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

!!The Metal Eating Family

* TomatoInTheMirror: The family are robots, but dont seem to be aware of it.

!!The Wishing Fairy

!!Dome of Doom Champions
->Gordo voiced by: KevinMichaelRichardson
->Aqualizer voiced by: PhilLaMarr
->Sumoto voiced by: KevinMichaelRichardson
->Ganeesh voiced by: KevinMichaelRichardson

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.
%%* TheBattledome
* EveryoneCallsHimBarkeep: 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 area to face Gordo.
* EverythingsBetterWithMonkeys: Gordo is one.
* LargeHam: Basically every fighter in the Dome of Doom with speaking lines, but especially Gordo and the announcer.
* LizardFolk: Reptor and Torto.
* MultiArmedAndDangerous: Ganeesh, who resembles a Hindu god.

* AIIsACrapshoot: ''Intentional'', seeing as Aku is their power source.
* FlamethrowerBackfire: The robot with the flamethrower arms is destroyed by them when Jack cuts off one arm and ignites the robots fuel with it.
* GatlingGood: One of the robots has two gatling guns for arms.
* InvisibilityCloak: One robot uses a combination of this and a pair of close combat PowerFist.

* TheHunter: An entire PlanetOfHats with these.
* ProudWarriorRace

->Voiced by: KevinMichaelRichardson

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

* BladeOnAStick: The Samurai Warrior has one of these.
* TheCollector: In this case, its warriors souls.
* TheJailer: 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.)
* NoodleIncident: 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.
* PsychopathicManchild: Demongo has shades of this.
* ShoutOut: One of the warriors Demongo summons is very clearly one of the TeenageMutantNinjaTurtles, just with a sumo wrestler outfit instead of a shell. Another heavily resembles {{Lobo}} and another MarshalLaw.

!!"The White Rabbit"

!!The Spartans

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

* DanceBattler: For the first part of the battle.

!!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.

* BountyHunter
* ChronicBackstabbingDisorder: Hinted at with Josephine.
* HugeGuyTinyGirl and UglyGuyHotWife
* ImprobableWeaponUser: Zeke's gauntlets.
* LikeAnOldMarriedCouple: Hell, they ''were'' married for a while.
* RevolversAreJustBetter: Josephine's weapon of choice.

!!Dust Zombies

* OurZombiesAreDifferent: Necromancy variety.

!!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.

* {{Badass}}: They are the creations of a god, and not of the mortal world. Their status is equivalent to that of an angel or extremely high-ranking demon. Jack admits they are the most powerful opponents he has ever faced up to that point.
* ChaseFight: 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.
* CombatParkour: 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.
* CurbStompBattle: Jack is all but defeated the instant one of the Minions' fists plants itself firmly into his face, sending him flying through the air only to meet more fists and blades coming at him from every direction. The attack is so overwhelming Jack is completely unable to defend himself and gets tossed around like a ragdoll before nearly being killed, snapping out of his shock only at the last possible instant. The rest of his encounters with them don't go any better.
* GlowingEyesOfDoom: The Minions of Set have solid blue eyes that glow brightly whenever they become alerted or agitated during hunting.
* HealingFactor[=/=]NighInvulnerable: 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.
* ImplacableMan: 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.
* NoHoldsBarredBeatdown: 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.
* ThePowerOfTheSun: 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.
* SealedEvilInACan: Originally plagued ancient Egypt until the Pharaoh of the time [[spoiler: summoned Ra]] and had them sealed away inside a stone sarcophagus. Aku releases them in the present to kill Jack.
* SuperStrength: And plenty of it. The Minions are strong enough to cut stone pillars to pieces, punch someone hard enough to send them flying through the air, and can slam someone into a stone wall with enough force to leave an impression of their body in it.
* TechnicolorFire: Each Minion has a weapon enshrouded in magical blue fire.
* WallCrawl: The Minions are capable of running on walls and even upside down on the ceiling.

!!The Three Travelling Creatures

!!The Guardian
->Voiced by: KevinMichaelRichardson

A powerful warrior that guards a time portal, waiting for TheChosenOne 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.

* AlwaysSomeoneBetter: Has Jack's ''number'' in combat.
* AmazingTechnicolorPopulation: He's blue.
* {{Badass}}: Being one of the only characters in the series that actually ''beats'' Jack in battle has to count for something.
* BadassInANiceSuit: He's very fond of his suit too.
%%* BaldOfAwesome
* BeefGate: A rare example outside video games.
* BerserkButton: Never, ever ruin his suit.
* CurbStompBattle: Jack initially looks like he's getting the upperhand when he hits with his own missiles, but he just shrugs them and shows he wasn't even taking the fight seriously and beats Jack with his bare hands. The only reason he doesn't kill him is because the portal gives him a sign telling him not to.
* DualWielding: First dual wields [[http://en.wikipedia.org/wiki/Sai_(weapon) sai]], then switches to dual wielding firearms.
* GunsAkimbo: One a machine gun, the other a machine gun[=/=]rocket launcher.
* HaHaHaNo: This is his response to Jack's request to use the time portal.
* [[YouAreNotReady He Is Not Ready]]: Is told this about Jack after their battle.
* HyperspaceArsenal[=/=]MultiMeleeMaster: Expertly uses [[KatanasAreJustBetter a katana]], sai, and eventually his fists.
* JiveTurkey: How he talks.
* LightningBruiser: Much like the Scotsman, he is able to match Jack's speed despite being much larger than Jack.
* [[MyFavoriteShirt My Favorite Suit]]: [[NoHoldsBarredBeatdown Jack really shouldn't have damaged it.]]
* NighInvulnerability: Missiles don't as much as scratch him.
* NoHoldsBarredBeatdown: His battle with Jack slowly turns from an even match to him on the giving end.
%%* NoNameGiven
* [[TheOnlyOneAllowedToDefeatYou The Only One Allowed To Defeat Me]]: Claims that TheChosenOne is this, and is therefore the only one that will use the time portal.
%%* RedEyesTakeWarning
* ShoutOut: His appearance, usage of a Katana, and the way Jack is reflected in his eyes are all reminiscent of Morpheus from ''Film/TheMatrix''.
* SuperStrength: As if his HyperspaceArsenal wasn't enough.
* TennisBoss: Subverted; Jack thinks he can beat him by bouncing his missiles back at him, but he's sadly mistaken.
* TimeAbyss: 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.

* CartoonCreature: It looks something like a bear, something like a cat, and it's [[AmazingTechnicolorPopulation light blue all over]]. At best, one can say it looks vaguely like a blue Anime/{{Totoro}} with three daisies on its head.
* GentleGiant: It's normally sweet, docile and inoffensive, if annoyingly dimwitted. But, for the love of all that's holy, do '''not''' tick it off!
* HulkingOut: When Jack is in danger, it undergoes a horrific transformation, growing several times larger, sprouting immense claws and [[MoreTeethThanTheOsmondFamily a huge array of claws]], turning red with mad-looking eyes, and having its daisies replaced by dead-looking treestumps.
* UnstoppableRage: Utterly ''mangles'' the bounty hunters who hurt Jack.


!!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.

* KnightOfCerebus: One of the beings that is treated seriously as this creature is independent from Aku's services.

!!The Shaolin Monks

!!The Labyrinth Thief
->Voiced by: Rino Romano

!!The Ninja

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

* {{Ninja}}: His only character trait.

* CatsAreMean: I and Am
* CulturedBadass: The Gentleman is dignified at all times and comes off as being rather posh.
* CurbStomp 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.

!!The Seasons of Death
->Spring Sprite voiced by: Grey [=DeLisle=]

->Voiced by: DaranNorris

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.

* ABoyAndHisX: A Robot and his Dog.
* AntiVillain: [[SlidingScaleOfAntiVillains Type II.]] Depends on how you view his mission.
* BadassInANiceSuit: You have to admit, this robot has style!
* FailureIsTheOnlyOption: The series isn't named ''Robot Assassin X9... and Lulu.'' ...sweet thing.
* FilmNoir: His episode is a salute to the genre.
* ForcedIntoEvil: He started as a robot that just followed his instruction commands. Later, Aku forced him to fight Jack by kidnapping his pet dog.
* GenreSavvy: He's seen Jack's handiwork against the bug-bots and knows that he fighting him is likely hopeless, but for LuLu's sake he goes in anyways.
* GlowingMechanicalEyes
* GunsAkimbo: To go with his mobster look.
* HeelRealization: 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.
* HeroicBloodshed: The bot may have been serving a greater evil purpose he was still only trying to save his dog.
* {{Homage}}: [[TheTerminator X9 looks a lot like the true form of the android assassin from a certain movie]]. Both are [[SkeleBot9000 android]] assassins that are good with guns and have [[GlowingMechanicalEyes glowing]] [[RedEyesTakeWarning red eyes]]. Bonus points since they're both considered obsolete models in their respective franchises.
* [[ImplacableMan Implacable Machine]]
* ItAmusedMe: As X9 explains, the scientist who gave him the "experimental emotion chip" did so simply because, "He was kinda funny that way."
* JustAMachine: Possibly averted due to Jack's reaction after X9 muttered his dying words.
* KilledOffForReal: [[spoiler: 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.]]
* LastOfHisKind: Due to the rest of the line of robots he was part of getting scrapped in favor of the bug-bots.
* MoreDakka: Of the pistol variety. Only once do we see him actually taking a accurate shot.
* PersonalityChip: His greatest strength and a biggest flaw.
* SlidingScaleOfRobotIntelligence: Average Joe Android. What he lacks in social skills he makes up for with musical ability and love for his dog.
* SugarAndIcePersonality: A calculating robot with a soft spot for puppies.
* SuperPrototype: Thanks to his emotion chip. In a way it was a prototype within a prototype.
* TrenchCoatBrigade: A member of one, anyway.
