History Characters / SAMURAIJACK

auses 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 [[DependingOnTheWriter 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.
* KickTheDog: Really likes doing this. Outside of [[ChronicBackstabbingDisorder 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 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.
* KnightOfCerebus: A Zigzagged example. In some episodes, such as the three-part Premiere Movie 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 [[LaughablyEvil complete clown with some hilarious lines]]. Basically, depending on the episode, he can make you laugh or scream. [[MoodWhiplash Sometimes both in the same episode]].
* LargeAndInCharge: Rules the world and has a ShapeshifterDefaultForm that is usually several stories high at the least.
* LargeHam: 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.
* LaughablyEvil: He's rather... goofy for being the UltimateEvil and all. Varies depending on the episode, there are some that present him as legitimately evil and a threatening figure. Or sometimes [[BewareTheSillyOnes a bit of both]].
* LikableVillain: He's a pretty funny guy, whenever he isn't performing any genocide, slavery, or treachery.
* MadeOfEvil: 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.
* MakeMeWannaShout: Aku can use loud screams powerful enough to damage the landscape as a form of attack.
* MeaningfulName: 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.
* MorphicResonance: He always has the same black, red and green color-scheme in every form he takes.
* NamesToRunAwayFromReallyFast: 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.
* 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.
* NoNonsenseNemesis: Despite his StupidEvil 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.
* ObviouslyEvil: Right down to his ''[[BilingualBonus name]]''!
* OneManArmy: Aku has destroyed countless armies all by himself. Nowadays though, he's grown lazy enough that he relies on [[MechaMooks robots]] to do the conquering for him, and hires {{bounty hunter}}s for other dirty work.
* 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]] [[OneManArmy on his own]] was going at too slow a pace for him.
* OurDemonsAreDifferent: Aku is a demonic being with vast powers of dark magic; including immortality, shapeshifting, and [[PlayingWithFire pyrokinesis]].
* 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.
* PhlebotinumKilledTheDinosaurs: He, or rather his original mindless form, was the comet that wiped out the dinosaurs.
* PlayingWithFire: Can toss blue fireballs at opponents.
* Really700YearsOld: Aku (as a sapient being) has existed for centuries or even millennia.
* SatanicArchetype: He's a [[DemonLordsAndArchdevils demon overlord]], who in the future turned the world into a post-apocalyptic wasteland, and lives in a hellish underworld (the Pit of Hate).
* 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 inside a tree instead of killing him. The first episode shows him breaking free and taking his revenge.
* ShapeshifterDefaultForm: 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.
* 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.
* SpikesOfVillainy: His head is covered in branch-like horns and whatever form he takes tends to have a spike on each joint.

* DiabolicalMastermind: Very cunning and decieving.
* DirtyCoward: 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 VillainExitStageLeft. While some might call this prudent rather than cowardly, his carelessness in other matters indicates that he really does do it because he's callow.
* DitzyGenius: While Aku can be smart and cunning, his plans are not always the most well-thought ones.
* DoNotGoGentle: 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.
* TheDreaded: He's called [[MeaningfulName Aku]] for a reason.
* DystopiaJustifiesTheMeans: Subverted. The entire world ''could'' be reduced to uniform misery and despair, but he'd rather it present [[HopeSpot some occasional beauty, hope, and peace...]] [[DoubleSubverted so that he can ''crush it like a bug.'']]
* EldritchAbomination: Spawned from the remains of a much larger one.
* EvenEvilHasStandards: Aku may be a being of unspeakable evil, but [[WouldntHurtAChild 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.
* EvilCannotComprehendGood: Given that Aku is the AnthropomorphicPersonification 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 HopeSpringsEternal 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.
* EvilGenius: 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.
* EvilIsBigger: Much bigger, but mostly because he prefers to be big as his standard form.
* EvilGloating: What's the point of hurting people if you don't get to revel in their expressions of horror, despair and hatred?
* EvilIsHammy: The way he talks is so bombastic and over the top!
* EvilIsPetty: 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 StupidEvil levels as he ''always'' backstabs anyone he makes a deal with, just to laugh at their misfortune.
* EvilLaugh: Sincere, sinister, and usually preceded by something terrible happening to someone.
* EvilOverlord: Currently rules the whole planet and expanding his empire beyond.
* EvilPlan: 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.
* EvilSoundsDeep: As his voice actor once said, "Evil comes from the ''belly.''"
* EvilSoundsRaspy: He has a raspy voice which matches his evil laugh.
* EyeBeams: 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.
* FangsAreEvil: His have the distinct Oriental pattern in which the canines curve outward.
* FauxAffablyEvil: 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 [[LaughablyEvil 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.
* 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.
* FourFingeredHands: Considering he's thoroughly evil, [[FourIsDeath there's probably a meaning to it]].
* GalacticConqueror: 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.
* GodOfEvil: He's an immortal and malevolent [[EldritchAbomination cosmic entity]] who is worshiped by an [[ReligionOfEvil evil cult]].
* HeroKiller: In "The Birth Of Evil", he [[OneManArmy slaughtered]] [[RedShirtArmy most of the soldiers]] serving under Jack's Father. He also made Jack's Father die 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.
* HolyBurnsEvil: Jack's divinely-forged sword causes him ''horrible'' pain with even the slightest cuts.

[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/img_1104.JPG]]
->Voiced by: {{Creator/Mako}} (Original), Greg Baldwin (Fusionfall, Season 5), Creator/FredTatasciore (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.
----
* AchillesHeel: Aku is very weak to divine magic as his MadeOfEvil 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 NoSell 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.
* TheAgeless: Immortal. That's pretty straightforward.
* ArchNemesis: To Jack.
* AttackOfTheFiftyFootWhatever: And he is only a ''fragment'' of what he came from.
* BackFromTheDead: The first thing he did when he came back to life in the premier was to attack the town, and TakeOverTheWorld.
* BadassBeard [[BeardOfEvil of Evil]]: That's a pretty stylish goatee of flame.
* BadassBoast: ''Who dares to summon the Master of Masters, the Deliverer of Darkness, the Shogun of Sorrow, Akuuuuu?''
* BadBoss: You're probably safer as one of his victims than one of his minions.
* BewareTheSillyOnes: Aku is a lovable goofball... and utterly evil.
* BigBad: 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.
* 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 - resulting in old-fashioned TV static.
* BreathWeapon: Can breathe fire in both his normal form and whenever he turns into a dragon.
* 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. He ''does'' remember them, he just chooses not to help - since he's the one who stole their oceans.
* CardCarryingVillain: 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.
* CharacterizationMarchesOn: In the pilot episodes, he's actually quite a fairly serious, ominous antagonist, lacking a lot of the dark sense of humor that would characterize him later on.
* ChronicBackstabbingDisorder: See StupidEvil. He nearly always betrays anybody he works with, even when he has nothing to gain from it.
* CombatTentacles: Whenever he's in octopus form (one of his favorites) or reverts to formlessness.
* TheComicallySerious: He's always funnier when he's trying to be serious. As Creator/GenndyTartakovsky stated, he's meant to have a serious personality but humorous at the same time.
* 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. 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.
* TheCorruption / TheVirus: 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.
* ADayInTheLimelight: "Aku's Fairy Tales", which focuses on his attempts to win over a group of children. Jack only appears in his stories.
* DarkIsEvil: In addition to being mostly black, his primal form is nothing but a billowing dark mass.
* DeadpanSnarker: 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.

!!Titular Character

[[folder:Samurai Jack]]



* 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: 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.
* 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, inspired by a group of bikers who called him "Jack" the same way one would call someone "dude" or "pal".
* NotQuiteFlight: He learns to "jump good" from a tribe of apes. After their training, he can jump so good that Aku mistakes it for flight.
* OddFriendship: The Scotsman is pretty much his closest friend. They're about as different as they come.
* OlderThanTheyLook: 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.
* OneManArmy: 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.
* 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.]]
* OOCIsSeriousBusiness: 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 has him using guns, bombs, and even a motorcycle. It's a pretty good indicator of just how BAD things have gotten, [[spoiler: he lost his sword]]. Even bigger indicator is when he sees smoke of a burning village and refuse to go there twice before his guilt of fifty years of failure forces him back.
* PapaWolf: 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.
* PerpetualFrowner: 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.
* ProtagonistTitle: Subverted. "Jack" isn't his real name, it's just an alias he picked up when he was sent to the future.
* TheQuietOne: Usually speaks only a few lines each episode; there are even a couple in which he appears, but has no dialogue at all.
* RedOniBlueOni: The calm, stoic blue to the Scotman's boisterous red.
* {{Samurai}}: Technically, Jack is a "ronin", as he is a Samurai with no liege.
* SamuraiPonytail: Jack fits pretty clearly into the first variation of the trope with his noble attitude.
* SanitySlippage: He's begun suffering from hallucinations in season 5, due to the guilt of having failed to stop Aku for decades.
* SetRightWhatOnceWentWrong: His primary goal is to find a way back to his own time so he can destroy Aku before the BadFuture comes to pass.
* ShirtlessScene: Not so much during the first season, increasingly as the show goes on, almost qualifies as a WalkingShirtlessScene at some points.
* TheSilentBob: 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 ''[[LargeHam never]]'' [[EvilIsHammy shuts up.]]
* SignificantBirthDate: As shown in "The Birth of Evil," he was born the very same day that his father originally defeated Aku.
* SlipknotPonytail: Also a magnet for this after season one (not as much as the ClothingDamage example, but it does happen).
* SpoiledSweet: Jack is very ''noble'' in both senses of the word, being an aristocrat by birth, and also a heroic man with high morals.
* TheStoic: [[NotSoStoic 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 [[LargeHam the]] [[VitriolicBestBuds Scotsman]].)
* 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.
* StrongFamilyResemblance: As an adult, Jack looks near identical to his father.
* SuddenlyAlwaysKnewThat: 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 TykeBomb.)
* SugarAndIcePersonality: Jack is reserved, stoic, and serious. He also is a genuine NiceGuy who goes out of his way to help those in need. He's also [[FriendToAllChildren good with kids.]]
* SuperReflexes: 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.
* TheTeetotaler: Every time he enters a bar or a canteen, he orders tea or water (sometimes used to make tea).
* ThrowingYourSwordAlwaysWorks: It's come up in a couple of desperate situations.
* TookALevelInCynic: In Season 5, due to spending 50+ years unsuccessfully trying to escape a BadFuture.
-->'''Jack''': There's no way home! There's nothing to fight for!
* TrueCompanions: 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 [[MoreHeroThanThou rowing the boat off the island]]. The fact Jack humored his challenges without complaint and was [[OutOfCharacterMoment uncharacteristically]] [[GrinOfAudacity 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).
* 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: The son of an Emperor, and trained in the arts of war.
* WhatMeasureIsANonHuman: Likely as a result of fighting them for so many years, Jack has developed this mindset in Season 5; he doesn't consider any of the robots that he's fought to be sentient beings, just "nuts and bolts" in his own words.
* TheWisePrince: He's actually a prince, and the day Aku appeared signaled the end of his sheltered childhood.
* WorldsBestWarrior: 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, [[spoiler: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 [[EvilKnockoff Mad Jack]].
* WouldHitAGirl: As shown when fighting [[DarkActionGirl Josephine, Princess Mira, and the Daughters of Aku]], Jack won't hesitate to attack women.
[[/folder]]

* DespairEventHorizon: 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.

* {{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 HeroicBSOD and saying, "It always seems bad at first, but then I find a way," before starting to kick ''serious'' ass.
* DepartmentOfRedundancyDepartment: 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''.
* DoubleWeapon: One of his Season 5 weapons is a [[RetractableWeapon retractable]] [[ProngsOfPoseidon trident]] with [[ShockAndAwe an electrified rod on the other end]].
* TheDrifter: He doesn't stay in one place for long in his never-ending quest to return to the past.
* EmpoweredBadassNormal: 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 TheAgeless.
* EverythingsBetterWithSamurai: He is a samurai, he is TheHero, and he kicks tons of ass.
* EvilKnockoff: Mad Jack, a being that was created from Jack's negative emotions.
* FishOutOfTemporalWater: 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, now riding a CoolBike and using guns.
* ForceAndFinesse: The Finesse to the Scotsman's Force. While both are MasterSwordsmen, Jack is the faster, more skilled, and cunning of the two, while the Scotsman is stronger, tougher, and better with modern weaponry.
* ForegoneConclusion: 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'' [[spoiler: eventually return to his own time]].
* FreeRangeChildren: Flashbacks of his childhood before Aku entered, showed that Jack was free to roam in his home despite being a prince.
* FriendToAllChildren: 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.
* FutureBadass: Shown briefly by the Guardian's time portal. Not that we needed ''any'' confirmation, but season 5's trailer has ''[[https://www.youtube.com/watch?v=VSrv_n4tw7w&t=3s proof]]''.
* GoodIsNotDumb: While he's not being hindered by ChronicHeroSyndrome, he's shown he can be very clever.
* GoodIsNotSoft: A sworn protector of the innocents and the biggest threat to all evil villains.
* HatDamage: Whenever he wears one, it's usually the first thing to go.
* HeroicSelfDeprecation: The fifth season pilot shows him sinking heavily into this and doubting his purpose, only to claw himself back up and regain it.
* TheHero: He was designed to be a very simple example of the classic hero.
* HonorBeforeReason: Which makes sense, since honor pretty much defines what a samurai is all about.
* HopeBringer: He's given the oppressed masses someone to rally behind against Aku.
* HumbleHero: 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.)
* IdiotBall: 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.
* InASingleBound: An episode has Jack going through TrainingFromHell 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.
* IncorruptiblePurePureness: Not Jack himself: one terrifying incident had him fighting TheCorruption 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.
* 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: 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 LikeCannotCutLike, the other was created by a race of Yeti in the hopes of defeating Jack. They fail.
* KnightErrant: He wanders the land, dispensing justice and hope.
* LanternJawOfJustice: The jaw's half the length of his face, and the man it's attached to is decisively [[ChronicHeroSyndrome 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.
* LightIsGood: 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 EvilKnockoff, naturally, replaces the white and darker grey in his robes with RedAndBlackAndEvilAllOver.
* LimitedWardrobe: Always appear to be wearing the same white gi - it's even unlimited in its limited-ness, because he keeps suffering ClothingDamage!
* MadeOfIron: 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.
* MartialPacifist: 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!"
* MasterSwordsman: While Jack is talented at many things, nothing compares to his swordsmanship, with which he can slice through bullets with ease.
* MosesInTheBulrushes: 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.
* MrFanservice: Oh so much. He's even got some fangirls in-universe!
* TheMusketeer: 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.
* 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: 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.
* 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, inspired by a group of bikers who called him "Jack" the same way one would call someone "dude" or "pal".
* NotQuiteFlight: He learns to "jump good" from a tribe of apes. After their training, he can jump so good that Aku mistakes it for flight.
* OddFriendship: The Scotsman is pretty much his closest friend. They're about as different as they come.
* OlderThanTheyLook: 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.
* OneManArmy: 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.
* 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.]]
* OOCIsSeriousBusiness: 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 has him using guns, bombs, and even a motorcycle. It's a pretty good indicator of just how BAD things have gotten, [[spoiler: he lost his sword]]. Even bigger indicator is when he sees smoke of a burning village and refuse to go there twice before his guilt of fifty years of failure forces him back.
* PapaWolf: 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.
* PerpetualFrowner: 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.
* ProtagonistTitle: Subverted. "Jack" isn't his real name, it's just an alias he picked up when he was sent to the future.
* TheQuietOne: Usually speaks only a few lines each episode; there are even a couple in which he appears, but has no dialogue at all.
* RedOniBlueOni: The calm, stoic blue to the Scotman's boisterous red.
* {{Samurai}}: Technically, Jack is a "ronin", as he is a Samurai with no liege.
* SamuraiPonytail: Jack fits pretty clearly into the first variation of the trope with his noble attitude.
* SanitySlippage: He's begun suffering from hallucinations in season 5, due to the guilt of having failed to stop Aku for decades.
* SetRightWhatOnceWentWrong: His primary goal is to find a way back to his own time so he can destroy Aku before the BadFuture comes to pass.
* ShirtlessScene: Not so much during the first season, increasingly as the show goes on, almost qualifies as a WalkingShirtlessScene at some points.
* TheSilentBob: 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 ''[[LargeHam never]]'' [[EvilIsHammy shuts up.]]
* SignificantBirthDate: As shown in "The Birth of Evil," he was born the very same day that his father originally defeated Aku.
* SlipknotPonytail: Also a magnet for this after season one (not as much as the ClothingDamage example, but it does happen).
* SpoiledSweet: Jack is very ''noble'' in both senses of the word, being an aristocrat by birth, and also a heroic man with high morals.
* TheStoic: [[NotSoStoic 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 [[LargeHam the]] [[VitriolicBestBuds Scotsman]].)
* 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.
* StrongFamilyResemblance: As an adult, Jack looks near identical to his father.
* SuddenlyAlwaysKnewThat: 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 TykeBomb.)
* SugarAndIcePersonality: Jack is reserved, stoic, and serious. He also is a genuine NiceGuy who goes out of his way to help those in need. He's also [[FriendToAllChildren good with kids.]]
* SuperReflexes: 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.
* TheTeetotaler: Every time he enters a bar or a canteen, he orders tea or water (sometimes used to make tea).
* ThrowingYourSwordAlwaysWorks: It's come up in a couple of desperate situations.
* TookALevelInCynic: In Season 5, due to spending 50+ years unsuccessfully trying to escape a BadFuture.
-->'''Jack''': There's no way home! There's nothing to fight for!

* BatmanGrabsAGun: 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. [[spoiler: This is because he lost his magic katana so he's forced by necessity to use ''any'' weapon he can get his hands on.]]
* BeardOfSorrow: 50 years wandering the future with no success will do that to you.
* BecauseDestinySaysSo:
** [[spoiler: It's heavily implied that he '''will''' be able to go back to the past... eventually. But for some reason the PowersThatBe have decreed it will be a very long time before that actually happens.]]
** [[spoiler: 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.]]
* BerserkButton: Put simply, evil sets him off.
* BewareTheNiceOnes: 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.
* BigGood: As the polar opposite of [[BigBad Aku]], of course he is.
* 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. As of Season 5 however, Jack plays this trope very, ''very'' straight, due to the series becoming DarkerAndEdgier and premiering on Creator/AdultSwim's Creator/{{Toonami}} block.
* CharacterDevelopment: 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 taken its toll on him.
* 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: Revealed to the viewers, but not known to Jack.
* CharlesAtlasSuperpower: He does many astounding, even 'impossible' things, all as a result of his training. For example, he learns to "jump good" by training with the contents of a small avalanche as training weights.
* 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.
* TheCoatsAreOff: The ClothingDamage 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 combatants to get their ass handed to them soon.
** SubvertedTrope in "Jack versus Mad Jack", where his robe gets torn but he keeps it on throughout the fight. It fits with him [[spoiler: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]].
* CombatPragmatist: Seems to have become this by Season 5, which is in stark contrast to his HonorBeforeReason 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 BadFuture for decades. And of course, there's the small matter that he's [[spoiler:lost his sword.]]
* 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 topknot. Once that pin's gone, you get some long, flowing locks [[{{Hammerspace}} that couldn't possibly fit into his tied-up hairstyle]].
* ConsummateLiar: He frowns on deception, but he can be a pretty good liar when he needs to be.
* CoolHelmet: Wore one in the pilot and another one in Season 5.
* CoolSword: His sword is made of the magic that can hurt those who have evil in them.
* DarkAndTroubledPast: 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.

this, on occasions when he is so perplexed that a simple confused stare wouldn't be enough.
* AtopAMountainOfCorpses: He ends up standing atop a mountain of robot corpses after defeating them.
* BackToBackBadasses: He and The Scotsman ever since the first time the two started working together.
* BadassAdorable: 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.
* BadassBack:
** 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.
* BadassBeard: In Season Five, he sports a prominent beard.
* BadassBiker: A [[https://www.youtube.com/watch?v=EkMFVV4jv8c Season Five preview]] shows him as one, with a ''bitchin''' CoolBike that he uses to dismantle Aku's MechaMooks.
* BadassBoast: "I am the lost son of the land you have pillaged. I am here to reclaim it."
* BadassLongRobe: He is a samurai, so he always wears a long white robe. [[{{Headscratchers}} How he cleans, fixes, or replaces his robe after getting it dirty or torn up from so many battles is unknown]].
* BadassNormal: Jack has fought all kinds of high-tech or supernatural villains with nothing but his skills and his divinely-forged blade.
* BadassPacifist: While Jack usually handle fight via violence, there have been moments where he defeats his enemies without said violence.
** Jack defeats Mad Jack simply by 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 ''tickling'' Sumoto.
** A flashback into his childhood has a young Jack dealing with a trio of bullies who took his toy from him by scaring a group of pigeons that to distract them long enough for him to retrieve said toy.
* BarbarianLongHair: He always had long hair, but the fifth season replaces his SamuraiPonytail with an unkept mane.
* BashBrothers: With The Scotsman.

[[caption-width-right:300:[[labelnote:Click here to see Jack as of Season 5.]][[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/samuraijackold_4.png]][[/labelnote]]]]
->Voiced by: Creator/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.
----
* HundredPercentAdorationRating: 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.
* TheAbyssGazesAlso: While fighting his EvilCounterpart 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.
* TheAce: He's seen learning more and more, and as the show progresses, he's always getting better at things.
* TheAgeless: He hasn't aged during the fifty year TimeSkip, a side effect from traveling through time.
* AloofAlly: 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.
* AppropriatedAppellation: 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.
* AsideGlance: He's somewhat prone to this, on occasions when he is so perplexed that a simple confused stare wouldn't be enough.

* WouldHitAGirl: As shown with the Daughters of Aku, Jack won't hesitate to attack women.

* HeroKiller: In "Birth Of Evil", he [[OneManArmy slaughtered]] [[RedShirtArmy 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.

* KnightOfCerebus: 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 [[LaughablyEvil complete clown with some hilarious lines]]. Basically, depending on the episode, he can make you laugh or scream. [[MoodWhiplash Sometimes both in the same episode]].

* 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.

[[folder:Jack's Father]]

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.

* BadassMustache: He has a moustache.
* BadassNormal: "Birth of Evil" shows Jack's Father taking on the shapeshifter Aku and winning.
* CoolOldGuy: '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.
* CreateYourOwnVillain: 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.

[[folder:Jack's Mother]]

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.

* OneManArmy: Aku tests the Minions' skills by setting them against a whole battalion of his own [[MechaMooks robotic soldiers]]. [[CurbStompBattle Obviously, the Minions gain victory in a matter of seconds]].

[[caption-width-right:300:Click [[labelnote:here]][[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/samuraijackold_4.png]] [[/labelnote]] to see Jack as of Season Five.]]

* OurDemonsAreDifferent: 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).

* Really700YearsOld: Aku (as a sapient being) has existed for centuries or even millenia.

** He does get his comeuppance in regards to this at times. One example being his deal with the Imakandi[[labelnote:*]]Aku made a deal to have them hunt down Jack, and they agreed to do it without any compensation. This ends up biting Aku back as the Imakandi garnered so much respect for Jack that they decide to let him go free instead[[/labelnote]], and his Hermit disguise[[labelnote:*]]Where he lured Jack into summoning a powerful Titan to destroy him, only to find out that Jack planned for this, sabotaged his efforts, and nearly destroys Aku in the process[[/labelnote]].

* TakeOverTheWorld: He already has, but apparently it's not enough.

!!Other Characters

[[folder:Homeslice, Cole Lampkin, and Brobot]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/a_kezdetek_2_gyerektv.jpg]]
->Homeslice voiced by: Creator/PhilLaMarr
->Cole Lampkin voiced by: Creator/RobPaulsen
->Brobot voiced by: Creator/KevinMichaelRichardson

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.

* AllThereInTheScript: Their names are only shown in the end credits.
* AmazingTechnicolorPopulation: Homeslice is magenta, Cole Lampkin is pale green, and Brobot is blue.
* AmbiguouslyHuman: As humans of natural skin color appear in the series, it's not known if they're humans or aliens that look human.
* JiveTurkey: In addition to calling the samurai "jack", their dialogue is just filled with urban slang.
* SmallRoleBigImpact: 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.

[[folder:The Canine Archaeologists]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/the_dogs.jpg]]
->Rothchild III voiced by: Creator/RobPaulsen
->[=McDuffy=] and Dreyfuss voiced by: Creator/JeffBennett

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 Animal}}s: They're descended from dogs that somehow evolved to become sapient.
* MyInstinctsAreShowing: 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.
* MrExposition: 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 Guy}}s: They're all very friendly, helpful and polite.
* {{Non Action Guy}}s: 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.

[[folder: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.

* DefeatEqualsExplosion: 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.
* RedEyesTakeWarning: 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.
* RedAndBlackAndEvilAllOver: 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.
* ReplacementMooks: InUniverse, 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.
* ZergRush: 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.

[[folder:The Woolies]]
->Voiced by: Creator/KevinMichaelRichardson, 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.

* AndIMustScream: The Black Sphere forced the Woolies into walking like animals and prevented them from speaking.
* MadeASlave: Their entire race was enslaved.
* SpaceJews: They even wear yarmulke-like hats in the flashback to their golden age.
* TookALevelInBadass: After being released by Jack, they stomped the Chritchellites easily.

[[folder:The Chritchellites]]
->Voiced by: Creator/TomKenny

A race of diminutive conquerors who enslaved the Woolies and took over their civilization, claiming it as their own.

* FauxAffablyEvil: 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.
* KickTheDog: Their treatment of the Woolies.
* LaserGuidedKarma: Once the Black Sphere is destroyed, their weapons become useless, and the Woolies use their superior size to drive them off.
* ANaziByAnyOtherName: Enslavers of SpaceJews.
* {{Sadist}}: They tortured the Woolies, as well as enslaving and ordering them around.
* ShockAndAwe: They use electrified spears as weapons (and "encouragement" to their slaves.)

[[folder:The Astronauts]]
->Frederick and Sergei voiced by: Creator/JeffBennett
->Technician voiced by: Creator/JenniferHale
->Idealist and Analyst voiced by: Creator/TomKenny

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.

* AllThereInTheScript: They are not named on-screen and their designations are only given in their episode's end credits.
* DoomedContrarian: 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.
* LudicrousPrecision: The guy with the calculator, calculating the odds of survival. [[NeverTellMeTheOdds Jack doesn't trust the math]].
* ShoutOut: The Astronaut in the green helmet looks very similar to George Jetson.

[[folder:The Three Blind Archers]]
->Voiced by: Creator/KevinMichaelRichardson, Creator/PhilLaMarr, and Creator/JoeAlaskey

Three incredibly skilled archers who guard a magical well at the top of an old tower.

* AnnoyingArrows: Subverted. These are some serious, robot-puncturing, tank-demolishing arrows.
* BeCarefulWhatYouWishFor: 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.
* BottomlessMagazines: 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.)
* HandicappedBadass: The three archers are blind, but still wipe out an entire army with no problem.
* OneManArmy: 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 ([[NinjaPirateZombieRobot that also look like vikings]]) in the space of a [[MadeOfExplodium very explode-y]] minute.
* SuperSenses: 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.
* VisualPun: 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 [[https://en.wikipedia.org/wiki/Three_Blind_Mice the Three Blind Mice]].

[[folder:Mad Jack]]
[[quoteright:179:http://static.tvtropes.org/pmwiki/pub/images/250mad_jack_5997.png]]
->Voiced by: Creator/PhilLaMarr

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.

* AnAesop: Jack does much better at containing his anger after the Mad Jack incident.
* ArrogantKungFuGuy: As if being an evil JerkAss wasn't enough, he's also very arrogant and rude.
* AxCrazy: He has shown to be unhinged, violent, and rather psychotic, and even attacks Jack when the latter meditates to seal him off for good.
* EnemyWithout: He's a manifestation of Jack's negative emotions.
* EvilCounterpart: Take a guess.
* EvilMeScaresMe: As Jack struggled with his dark half, he saw the reflection of his own eyes in his sword and to his horror saw they bore great resemblance. Finding his peaceful center, Jack stepped back and calmed himself, causing all of his negative emotions to fade away.
* HairTriggerTemper: Since he was born of regular Jack losing his temper.
* JerkAss: Possesses none of Jack's nobility or manners.
* PsychoticSmirk: Gives a rather unsettling smirk when he's about to attack Jack.
* RedEyesTakeWarning: Has red eyes that represent his nature.
* RedAndBlackAndEvilAllOver: He wears a dark version of Jack's robe with red trim. Oh, and he sports [[RedEyesTakeWarning blood-red eyes]] that represent his AxCrazy nature.
* {{Samurai}}: Physically, at any rate, although he has none of the discipline of ''bushido.''
* SheatheYourSword: How Jack ends up defeating him.
* VillainousBreakdown: After Jack saw the reflection of his own eyes in his sword, he backed out. Jack then claims the fight was over, stating that the negative emotions that formed Mad Jack were gone, meaning Mad Jack didn't exist. Refusing to let Jack look down on him, Mad Jack boasted that he was real and charged toward Jack to deliver the final blow, but Jack remained in a meditative position, not even bothering to defend. As he was to strike Jack down, Mad Jack was instantly in Jack's control, able to do nothing except scream in impotent fury and defeat before he was sealed off by Jack.

[[folder:The Triseraquins]]
->Connery voiced by: Creator/JeffBennett
->Guiness voiced by: Creator/MarkHamill
->Ringo voiced by: Creator/JessHarnell

An alien tribe who live in a floating city. Their city is menaced by Aku, who demands a simple price for sparing them...

* AllThereInTheScript: They are only named in the episode's end credits.
* AtlantisIsBoring: At least, until Aku showed up.
* CrazyPrepared: They have an army at the ready in the event that Aku betrays them. It doesn't work.
* EasilyForgiven: Jack doesn't hold anything against them, knowing that Aku can manipulate anyone with a deal just too good to pass up.
* EtTuBrute: They aren't inclined toward villainy, but they're being blackmailed.
* HorribleJudgeOfCharacter: 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.
* NoCelebritiesWereHarmed: Their names and voices are most likely references to UK celebrities Sean Connery, Alec Guinness, and Ringo Starr.

[[folder:The Lava Monster]]
[[quoteright:314:http://static.tvtropes.org/pmwiki/pub/images/the_lava_monster.png]]
->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.

* BloodKnight: 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.
* DeathCourse: 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.
* DeathSeeker: 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''.
* DuelToTheDeath: The only way to be free of his curse is to ''lose'' one.
* IDieFree: His ultimate goal is to die in battle so that he can be free of Aku's curse. Jack grants it to him.
** DyingAsYourself: Just prior to his death, he becomes human again.
** GoOutWithASmile: As he dies, he smiles due to being happy that he's finally free of the curse.
* EasilyForgiven: Once Jack learns his backstory, he quickly forgives him for all the warriors he killed.
* ForcedToWatch: Rather than killing him, Aku burned his kingdom to the ground. That was before cursing him.
* ProudWarriorRaceGuy: Dying in battle is the only true death for him.
* LightningBruiser: He's a stone giant who's quick enough to keep up with Jack in a swordfight.
* RapidAging: Upon being freed from the curse he rapidly ages from a young man to an elderly one as he dies.
* WorthyOpponent: Sets up a DeathCourse to find one strong and skilled enough to beat him.

[[folder:The Gangsters]]
->Boss voiced by: Creator/MauriceLaMarche
->Mr. Pibbles voiced by: Larry Cedar
->Mr. Shine and Knuckles voiced by: Creator/KevinMichaelRichardson
->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 ThePerilsOfPenelopePitstop.

* {{Expy}}:
** The gangster's boss, "Don", is clearly based on gangster characters played by actor Edward G. Robinson: not only do they [[http://vignette2.wikia.nocookie.net/samuraijack/images/5/59/Don_1.png/revision/latest?cb=20100615083610 look]] [[http://image.toutlecine.com/photos/p/e/t/petit-cesar-1931-05-g.jpg alike]], but they also share the same verbal tic (peppering their speech with heavily accented "yeah!" and "see?" for emphasis).
** Mr. Shine bears a striking resemblance to [[TheThreeStooges Larry Fine.]]
** The entire gang is clearly based on the Ant Hill Mob from ''WesternAnimation/ThePerilsOfPenelopePitstop'' and ''WesternAnimation/WackyRaces''.
* GoldfishPoopGang: 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.
* HeelFaceDoorSlam: 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. [[VillainDecay At least they decided to stop blowing up animal shelters]].
* HiddenDepths / OffscreenMomentOfAwesome: 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.)
* IOweYouMyLife: Jack interrupts an assassination attempt on them, earning their respect and a position in their gang.
* KarmaHoudini: 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.
* KickTheDog: 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.
* TheMafia: Played for laughs.

[[folder:The Goddess of Water and the Elementals]]
->Fire Creature voiced by: Music/GreyDeLisle

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.

* DefeatingTheUndefeatable: The Goddess and her creations are among the very few who've ever been able to repel Aku.
* ElementalRockPaperScissors: How Jack manages to dispatch all the elementals is playing their powers against each other.

[[folder: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.

* AudienceSurrogate: They tell Aku what the audience is thinking, particularly when they start to pick at the flaws in his stories.
* ChildrenAreInnocent: Aku attempts to exploit this to garner sympathy and respect from the children.
* HeroWorship: 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.

[[folder:Tribe]]
->Monkey Man voiced by: Creator/JeffBennett

A tribe of round little white-furred apes (and a wild man who lives alongside them).

* ActualPacifist: Until Jack trains them; then they become {{Martial Pacifist}}s.
* AllThereInTheScript: The Monkey Man isn't named onscreen.
* CharlesAtlasSuperpower: The White Apes have an incredible ability to jump enormous distances due to a regimen of training that they go through.
* NotQuiteFlight: Not flight, [[InASingleBound jump good]]!
* RaisedByWolves: 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.
* 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.

[[folder:The Two-Headed Worm]]
->Voiced by: Creator/TimCurry and Creator/PhilLaMarr

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

* BlatantLies: When one of them tells you that one head only tells the truth and the other only lies, ''it might be lying.''
* FinishingEachOthersSentences: Some of their sentences have one another interrupt to say the rest.
* KnightsAndKnaves: The story kind of demonstrates the biggest flaw of that old riddle.
* ObviouslyEvil: Its a giant, scary, too-headed worm with huge teeth that hisses when it talks. Kind of makes one wonder why ''anyone'', much less Jack, trusted it.
* OnlySmartPeopleMayPass: Their riddle consists of Jack guessing which one is truthful, and which one is a liar. They grant him exactly one question to ask. Ultimately, Jack [[AwesomenessByAnalysis correctly deduced who is really truthful by forcing the lying worm to indicate he is the truthful one, which is in fact false.]]
** ShaggyDogStory: And then Jack discovered that both worms are liars. The End.

[[folder:The Metal Eating Family]]
->Woman voiced by: Creator/JenniferHale

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.

* BitchInSheepsClothing: They were nice to Jack at first. Then they start to get violent and try to eat his blade.
* MonstrousCannibalism: 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.
* TomatoInTheMirror: The family are robots, but don't seem to be aware of it.

[[folder:The Gargoyle]]
->Voiced by: Creator/JeffBennett

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

* DieLaughing: Jack may had defeated him, [[TheBadGuyWins but he had the last laugh.]]
* EvilBrit: A sort of Yorkshire accent.
* TheBadGuyWins: He laughs as he crumbles to dust, because he knows that Jack and the fairy are doomed without him.

[[folder:The Wishing Fairy]]
->Voiced by: Creator/JenniferHale

* BenevolentGenie: With a rather major drawback - only one wish, ever.
* DamselInDistress: Her tale starts when she's somehow captured by the gargoyle.
* TakingAThirdOption: Unable to break from her prison, and Jack's hand being stuck, Jack opts to wish for their freedom instead.

[[folder:Dome of Doom Champions]]
->Gordo voiced by: Creator/KevinMichaelRichardson
->Aqualizer voiced by: Creator/PhilLaMarr
->Sumoto voiced by: Creator/KevinMichaelRichardson
->Ganeesh voiced by: Creator/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: Exterior shots of the Dome of Doom are reminiscent of Thunderdome.
* 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 arena to face Gordo.
* EverythingsBetterWithMonkeys: Gordo is a simian-like alien.
* IceCreamKoan: ''Everything'' that Ganeesh says.
* 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.
* ScrewThisImOuttaHere: Reptor hightails it out of the arena after Jack has cut off his extensible tongue and killed the other champions.
* ShoutOut: The Aqualizer is one to Blaster from MadMax. Underneath his helmet, Aqualizer is actually a harmless, weak sluglike creature who can't fight on his own.
* TheToothHurts: Jack disables Miotis by cutting out his fangs.
* UnstoppableRage: Gordo goes into a state like this when he's been hurt. It still doesn't do much to help him.
* WeaksauceWeakness: Sumoto, the most formidable of the champions, has one: [[spoiler:he's ticklish.]]
* WolverineClaws: The Claw's signature weapons.

[[folder:The Scotsman's Wife]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/3d6c13e6f17fac79b2eb196a8deac48a.png]]
->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).

* ActionGirl: When properly enraged, she can turn into butt-kicking OneWomanArmy.
* AffectionateNickname: The Scotsman gives her a variety of cute nickname, such as "Muffin".
* BadassNormal: She may not have any powers herself, but she's not afraid to fight anyone who's powerful.
* BerserkButton: Refer to her size and you perish.
* BirdsOfAFeather: She is just as [[BoisterousBruiser boisterous]] ([[BruiserWithASoftCenter with an equally soft heart]]), [[fieryRedhead fiery]], and [[BraveScot gutsy]] as the Scotsman is.
* BruiserWithASoftCenter: 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 [[SickeninglySweethearts (and she's not afraid to show it).]]
* ComplainingAboutRescuesTheyDontLike: 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 [[BerserkButton "fat,"]] Jack and the Scotsman, who were being worn down by a massive ZergRush would have been killed, and she would have been "sacrificed."
* DamselOutOfDistress: 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 [[{{Headscratchers}} is anyone's guess]], but it was likely due to the RuleOfFunny.
* DeadpanSnarker: She throws around sarcasm and sardonicism like no tomorrow.
* EyeScream: Pokes several of the demons' eyes out.
* FatBitch: She's fatter than her husband, and has an even worse temper. Just don't ever mention her weight in front of her.
* FieryRedhead: Stereotypical Scottish temper.
* FloweryInsults: 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).
* GroinAttack: Responds to the Master of the Hunt calling her fat by punching him right in the clock schpiel.
* HairTriggerTemper: 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.
* HappilyMarried: Rarely shows it, but it's there. But we'll ''never'' understand it.
* InformedAbility: According to her husband -- who is [[SickeninglySweethearts hardly an impartial judge]] -- she sings "like an angel". Her voice isn't actually pleasant though. Then again, [[FridgeBrilliance considering what the Scotsman's idea of a "beautiful voice" is...]]
* InsistentTerminology: "I am not fat! I'm stout!"
* JerkWithAHeartOfGold: 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.
* NoNameGiven: Like her husband, her name is never brought up.
* OneWomanArmy: Defeated the whole drone army which Jack and The Scotsman, who are BackToBackBadasses, were not even able to defeat together with their swords!
* ShockwaveStomp: She can create one of these by punching the ground.
* {{Stout|Strength}} SuperStrength: She's a powerhouse much like her husband.
* TinyGuyHugeGirl: The Scotsman may be huge but she is ''bigger'' and ''taller'' than him.
* {{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.
* UnstoppableRage: Destroys the entire demon army holding her captive with her bare hands (and feet, and teeth, and forehead...)

[[folder:The Celtic Demons]]
->Voiced by: Creator/PhilLaMarr and Creator/JeffBennett

A clan of demonic robots, or possibly robotic demons, serving the Master of the Hunt

* AmbiguousRobot: They're demons! With robot insides!
* BehindTheBlack: When Jack tosses a pebble to the gates of the Castle of Bone, five demons pop out of nowhere with guns at the ready.

[[folder:The Ultra-Robots]]
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/250px-ultra_robots_6600.png]]
->Voiced by: KevinMichaelRichardson

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.

* AIIsACrapshoot: ''Intentional'', seeing as Aku is their power source.
* CurbStompBattle: Deal one to Jack in their first fight thanks to his sword being unable to cut through them. When he gets the PowerFist 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.
* FamousLastWords: The lead bot can only think of one word when Jack cleaves him in half, with some {{divine intervention}}.
-->'''Lead Bot:''' [[ThisCannotBe Unbelievable]]...
* FlamethrowerBackfire: The robot with the flamethrower arms is destroyed when Jack cuts off one arm and ignites the robot's remaining 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.
* KatanasAreJustBetter: The leader droid has a katana meant to simulate Jack's.
* {{Magitek}}: Their power source is actually Aku's essence.
* MoreDakka: The robots that uses projectiles for weapons uses this style of attack.
* NoSell: 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. [[spoiler: 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]].
* RedEyesTakeWarning: They have red eyes and they are ''very'' dangerous.

[[folder:Extor]]
->Voiced by: Creator/JeffBennett

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.

* TheAtoner: The robots he created are invincible mechanical monsters; helping Jack destroy them is his effort at atonement.
* {{Expy}}: His name recalls Genndy's previous creation, {{WesternAnimation/Dexter|sLaboratory}}; his voice is a homage to Creator/JerryLewis in ''Film/TheNuttyProfessor'' (probably now better-known for another expy, [[WesternAnimation/TheSimpsons Professor Frink]]).
* MyGodWhatHaveIDone: His realization once Aku betrays him.
* PowerFist: Extor creates a powerful mechanical gauntlet for Jack's arm; it augments Jack's strength significantly and allows him to slice through the admanatium body of the robots. Shame it runs out of power when there's one bot left.
* YouSaidYouWouldLetThemGo: Unsurprisingly, Aku did not keep his word and Extor's attempt to protect his village was all for naught. Aku's betrayal motivated Extor to redeem himself by crafting a strength-enhancing gauntlet, [[NiceJobFixingItVillain which is the only thing that allowed Jack to defeat the robots]]... Well, [[DivineIntervention mostly]].

[[folder:The Three Monks]]
->Monk #1 voiced by: Creator/CoreyBurton
->Monk #2 voiced by: Creator/KevinMichaelRichardson

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.

* ComicallySerious: 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.
* HeroicSecondWind: When Jack is down, the monks speak to him telepathically, testing his resolve.
* MaybeMagicMaybeMundane: 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?
* NotSoStoic: 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.
* TheQuietOne: They're not talkers.
* TheStoic: They don't show much emotion.

[[folder:The Farting Dragon]]
->Voiced by: Creator/ClancyBrown

A dragon with a massive intestinal problems whose daily expulsion of gas plagues a nearby city.

* ApologeticAttacker: She would ''love'' to stop inundating the nearby town with rancid vapors.
* BiggerOnTheInside: A rare case where this applies to a living creature. When Jack crawls down her throat to deal with the problem, he finds a WombLevel 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.
* SamusIsAGirl: Her voice seems masculine at first, until Jack discovers that the problem is [[MonsterIsAMommy a partially-hatched baby dragon]] in her womb.
* VisualPun: To the Bruce Lee film, ''Film/EnterTheDragon.''

[[folder:The Imakandi]]
->Voiced by: Creator/KevinMichaelRichardson

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

* CatFolk: Lion folk.
* DidYouJustFlipOffCthulhu: When Aku comes to take Jack, they tell him to his face that they are letting Jack run free before making their exit.
* HuntingTheMostDangerousGame: The samurai is worthy prey.
* PantheraAwesome: They have lion-like heads, adding more to their appeal as a race of hunters.
* PlanetOfHats: A whole world of TheHunter.
* ProudWarriorRace: Their leader gives a laconic speech that explains this very succinctly. Aku was willing to pay them very, very well. They don't want the money, they want the hunt.
* WorthyOpponent: They love it whenever their prey gives them a real challenge. So much that when they finally catch it, they'll let it go out of respect. [[GenreBlindness Aku must be kicking himself for not seeing this coming as soon as they said they didn't want money]] (it's #44 on [[EvilOverlordList the list]] for a ''reason'', Aku).

[[folder:Demongo]]
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/250px-demongo-1_9260.jpg]]
->Voiced by: Creator/KevinMichaelRichardson

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

* AssholeVictim: 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.
* BadassBoast. "I am the dealer of destruction, the merchant of doom! And I seek you, Samurai Jack."
* BladeOnAStick: The Samurai Warrior has one of these.
* {{Catchphrase}}: "My Mastaaaah".
* TheCollector: In this case, he collects and enslaves 'essence'.
* CurbStompBattle: 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.
* DarkIsEvil: Just like Aku, he's a ruthless black demon.
* DirtyCoward: Without his enslaved warriors, Demongo is a sniveling coward who begs and pleads for his life.
* HeroKiller: 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.
* InformedAbility: 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.
* 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.)
* KilledOffForReal: Is killed by Aku for failing to kill Jack.
* LargeHam: Much like his master.
* NobleDemon: He seemed very loyal to Aku, calling him his master and even seeking forgiveness from him.
* NoodleIncident: 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.
* OurDemonsAreDifferent: A demonic collector of essence.
* PsychopathicManchild: Demongo has shades of this, including sticking out his tongue and making silly taunts.
* 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 ComicBook/MarshalLaw.
* SquishyWizard: His essence-stealing powers make him nearly unbeatable, but as he cheerfully admits, he has basically no fighting skill of his own.
* YourSoulIsMine: Anybody killed by him or his imprisoned warriors joins them in his collection.
* YouHaveFailedMe: Aku destroys Demongo for his failure.

[[folder: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.

* {{Determinator}}: Their response to the very real threat of a ForeverWar? HoldTheLine.
* ProudWarriorRace: They realize that they are doomed, and they are committed to dying well. The King mentions that he is the ''fifth'' king to fight in the war.
* RoyalsWhoActuallyDoSomething: The Spartan King leads his men from the front lines. His son does as well.
* WarIsHell: Especially one that can't be won.

[[folder:The Mechanical Beast and Minotaur Robots]]

An insane AI who's conquered all the lands surrounding its lair aside from the Spartan Kingdom.

* AIIsACrapshoot: 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.
* ZergRush: The minotaur robots are simply sent in en masse, over and over. This isn't WeHaveReserves, though: after each defeat they drag their fallen comrades or their own lost body parts back for repair.

[[folder:Caccitore]]
->Voiced by: Bob Joles

A sleazy slob who takes advantage of Jack's temporary BalefulPolymorph to climb to the top of his particular field - making animals fight to the death for the amusement of scumbags.

* AllThereInTheScript: His name is only shown in the end credits.
* BadBoss: His prize-fighting chicken doesn't receive medical care, or adequate food, or anything.
* FatBastard: He's very portly and clearly not a very pleasant person.
* ItsAllAboutMe: Carried to a comical extreme. When it looks like he's going to feed Jack, he just noshes on lasagna and continues starving Jack.
* JustAStupidAccent: Even when he's alone, he doesn't actually speak Italian - only broken English with a comically thick accent.
* KarmicTransformation: He happens to bump into the same ''extremely'' cranky wizard who cursed Jack, and... well...
--> '''Chicken with a stupid accent:''' Bock-a, bock-a!
* MeaningfulName: His name comes from an Italian dish containing chicken.

[[folder:DJ Salvatore]]
->Voiced by: Creator/KevinMichaelRichardson

A rave DJ whose magical rhythm hypnotizes the children of a town Jack passes through into becoming "children of Aku".

* BaldOfEvil: He's completely bald.
* CoolShades: Wears a pair of neat-looking shades. They get destroyed after Jack beats him.
* DanceBattler: For the first part of the battle, allowing him to match Jack blow-for-blow.
* EvilSoundsRaspy: He has a guttural, raspy voice.
* ForTheEvulz: Possibly the only reason why he has the kids raid the village is for the hell of it.
** Considering how he works for [[EvilIsPetty Aku...]]
* GatlingGood: When using his PoweredArmor.
* GoldTooth: [[ImprobableWeaponUser Which can shoot lasers!]]
* JiveTurkey: 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:''' What''ever!''
* LeanAndMean: He's rail thin.
* MusicalAssassin: A DJ who uses hypnotic music to brainwash kids into raiding villages. Seems about right.
* PoweredArmor: Uses a special wristwatch to create this from his DJ equipment.
* RedHerring: 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.
* RhymesOnADime: 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!
* WhatHappenedToTheMouse: 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.

[[folder:Olivia and her Father]]
->Olivia voiced by: Creator/KathSoucie
->Olivia's father voiced by: Michael Patrick Bell

Two of the townsfolk affected by DJ Salvatore's dance beats.

* BrainwashedAndCrazy: Olivia is mind-controlled by DJ Salvatore to become a thief.
* InelegantBlubbering: Olivia's father incessantly bawls over his daughter leaving him and being controlled by the DJ's music.
* {{Ruritania}}: Their village is vaguely Bavarian.
* TearsOfJoy: Both Olivia and her father cry with joy after they reunite at the end of the episode.

[[folder:Josephine and Ezekiel Clench]]
->Josephine Clench voiced by: Music/GreyDeLisle
->Ezekiel Clench voiced by: Creator/JohnDiMaggio

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

* BountyHunter: Zeke has quite a reputation: Josephine's success relies on ''not'' having one.
* ChronicBackstabbingDisorder: Hinted at with Josephine.
* DistractedByTheSexy: 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.
* HollywoodRestrainingOrder: Hilariously, ''he'' took out a restraining order on ''her.'' It requires her to be no less than 150 feet from him.
* HugeGuyTinyGirl: Ezekiel is taller than Josephine.
* ImprobableWeaponUser: Zeke's gauntlets. Which turn out to be very multifunctional: pistols, DualWielding knives, bola launchers, tasers, and - of course - clenching.
* LikeAnOldMarriedCouple: Hell, they ''were'' married for a while.
* NiceJobFixingItVillain: 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.
* NoodleIncident: It's never said just what caused them to break up in the first place, [[ChronicBackstabbingDisorder but Josephine's actions]] at the end give the viewers something of an idea.
* ParasolOfPain: Josephine uses one, its barbed ends used to restrain a victim, and a grapple concealed within to hook one.
* PlayingCardMotifs: 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.)
* RevolversAreJustBetter: Josephine's weapon of choice.
* UglyGuyHotWife: Ezekiel's not exactly what one would call handsome, while Josephine is a complete knockout.
* TheVamp: Josephine. She seduces Jack to try and capture him.

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

* MadeOfPlasticine: Most of them are reduced to powder with a single swing. But there are a ''lot'' of them.
* OurZombiesAreDifferent: Necromancy variety.
* ZergRush: They attempt to swamp Jack with sheer numbers over and over. It gets pretty harrowing.

[[folder:The Minions of Set]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/setminionsof_1871.jpg]]

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.

[[caption-width-right:350:Unmasked]]

->Voiced by: Creator/GreyDeLisle and Creator/TaraStrong

A coven of assassins under Aku's command that have been trained for one purpose: kill Samurai Jack once and for all.

* AbusiveParents: Their Mother and the older members of the cult made spend every waking moment of their lives training and had them punished if they do anything else or show any signs of weakness.
* AlwaysIdenticalTwins: They all have different hairstyles, but aside from that they're damn near impossible to tell apart.
* AmazonBrigade: They are part of an all-female clan of assassins that appear to serve as Aku's most elite warriors.
* BeatThemAtTheirOwnGame: Essentially Aku's intent for them. Jack was so powerful, skilled, and nigh unstoppable because he was raised from childhood to be the WorldsBestWarrior. So Aku did the same with his own group of assassins.
* BrainwashedAndCrazy: Part of the training they receive is psychological molding done by cruel overseers; they start to see Aku as a benevolent entity and Jack as the destructive force.
* DarkActionGirl: In the Season 5 trailer, they are shown to be Jack's most deadliest foes to date, even managing to wound the samurai in one of their encounters.
* EvenEvilHasLovedOnes: The Daughters do have some semblance of compassion for each other, but this is discouraged by the rest of the cult. It would appear that they do seem to love their mother too, albeit they don't realize how toxic it is.
* EvilCounterpart: Samurai Jack was raised from an early age to defeat Aku, and spent his young life travelling the world and receiving exotic training so that he could one day accomplish that goal. The Daughters, meanwhile, are Aku-worshipping ninjas who have spent most of their lives being trained specifically to kill Jack.
* KnightOfCerebus: While Aku's robots are clearly just as pathetic as ever, ''these'' gals mean business, able to wound and frighten even Jack.
* LaserGuidedTykeBomb: They've been trained their entire life solely to kill Jack. They will not back out. They will not stop. They will either kill him or die trying.
* MalevolentMaskedWomen: All of them are shown to be wearing [[https://en.wikipedia.org/wiki/Noh Noh]] like masks when they are sent on their mission to kill Jack.
* MassiveNumberedSiblings: There are seven of them and they [[UpToEleven were all born at the same time.]]
* NoNameGiven: The main Daughter is named Ashi, so presumably, the others have names too.
* QualityOverQuantity: There's only seven of them compared to the ''armies'' of mooks, bounty hunters, and assassins Aku has thrown at Jack over the years. However, each of them were trained their entire lives with the sole purpose of killing Jack, making them a much greater threat than the rest of Aku's forces.
* ReligionOfEvil: The Daughters are part of a cult that evidently worships Aku, and their lair prominently features a stone altar over which looms a statue of their master.
* RuleOfSeven: The Daughters are part of a cult with a seemingly large membership, but it seems there are seven actual assassins, trained to work in a near-perfect synchronization.
* TragicVillain: As big of a threat they are to Jack, the first episode makes it abundantly clear that they're just as much victims as anyone else. They were born to an Aku-worshipping cult leader who raised them from birth to be how they are, complete with brutal punishments and beatings. They never had any choice from the moment they were born.
* TrainingFromHell: From an early age, the Daughters were subjected to brutal, one-sided pit-fights against adult members of the Aku cult, and were punished for showing any sign of cowardice or weakness. By the time they're fully grown, however, the Daughters are able to easily defeat lesser members of the cult.
* TykeBomb: Each daughter goes through training to kill Samurai Jack since childbirth.

[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/ashi_9.png]]
[[caption-width-right:200:Adult Ashi]]
The only named Daughter thus far, and also the one with the most CharacterDevelopment thus far. (As of now, all Tropes that apply to her sisters also apply to her.)

* DaddysLittleVillain: For now, she's completely loyal to Aku, possibly more than the others.
* {{Expy}}: She looks like a black haired [[WesternAnimation/SymBionicTitan Princess Ilana]]
* TheLeader: She seems to be the head of the assassin group, possibly meaning she's better skilled and has more potential than the others.
* WhiteSheep: While the others seem to have little personality or emotion, Ashi stands out, being curious, inquisitive, and possibly even suspicious, running off on her own and questioning her surroundings.
* VillainousWidowsPeak: Her hairstyle.

[[folder:High Priestess]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/img_1115.PNG]]
->Voiced by: Creator/GreyDeLisle

The mother of the seven Daughters of Aku and the leader of the cult worshiping Aku.

* AbusiveParent: She subjects her children to TrainingFromHell and has them beaten for any failures (such as '''look''' outside).
* AxCrazy: Was the fact that she is the leader of a cult that worships the evolved form of a primordial darkness who abusively trains her seven daughters to be assassins of said evolved form of a primordial darkness any indication?
* BadBoss: She's more than willing to maim or torture her children if they don't preform to her expectation.
* CleanPrettyChildbirth: Despite the dark and evil nature of the temple, she pulls this off and then some, managing to stand and conduct the ritual after ''giving birth to septuplets'' with minimal aid. Most real mothers wouldn't have survived without heavy sedative medication and surgery.
* TheFaceless: Her face is shrouded in darkness while giving birth to her daughters. While the Daughters' are bare-faced before graduating, the High Priestess has not revealed her face.
* FauxAffablyEvil: Again, towards [[AbusiveParents her own children]]. The best example has to be Ashi is caught looking outside. She calmly and motherly explains why she wants Jack dead...before grabbing the girl by the throat, throwing her across the room and having her beaten.
* KnightOfCerebus: Her first scene marked the point where the season's {{Darker and Edgier}} atmosphere made itself known. Every scene with her in them had some of the darkest moments in the series, to date. Not even ''Aku'', at his absolute worst, compares to her.
* OffingTheOffspring: While she doesn't plan on killing her daughters, she once tried to drop Ashi with the end of her staff instead of helping her daughter out.
* ReligionOfEvil: Leads a cult that worships Aku as a benevolent deity.
* TheSocialDarwinist: She encourages her children to abandon any one of them who falls behind, seeing this as a sign of weakness that should be punished by death.
* WouldHurtAChild: Makes an entire practice out of this when training her children, to the point where she's willing to have Ashi brutally beaten simply for looking outside.

[[folder:Scaramouche the Merciless]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/image_488.png]]
->Voiced by: Creator/TomKenny

A robot assassin capable of controlling objects with a flute and his voice.

* AffectionateParody: He's basically a sendup of the goofier opponents Jack had faced off against in the previous seasons. He serves as a lead-in for the [[KnightOfCerebus Daughters of Aku]] that Jack would have to face an episode later.
* AintTooProudToBeg: After Jack does a number on him [[spoiler:by using his tuning fork sword's ability against him]], he tries to plead with Jack for his life. See HalfTheManHeUsedToBe below to see how far ''that'' got him.
* AssholeVictim: As amusing as Scaramouche is, he's still a murderer of innocent men, women, and children. After Jack already defeated him in combat, he deserved to be [[KickTheSonOfABitch summarily executed]].
* AxCrazy: He slaughtered an entire village just to get Jack's attention.
* BewareTheSillyOnes: That said, he still completely slaughtered a whole village solely to draw Jack out, and was able to hold his own against Jack for longer than most bounty hunters.
* BunnyEarsLawyer: He's a silly, jovial scatting robot who casually calls Jack "babe" and contacts Aku on a smartphone. He also massacres an entire town and gives Jack a truly impressive fight through the use of supernatural musical abilities and dagger fighting.
* CardCarryingVillain: Refers to himself as the "Pied Piper of Ruination", "Crooner of Carnage", and "Ambassador of Annihilation", among other titles.
* CellPhonesAreUseless: Averted. He's easily able to call Aku from the middle of nowhere.
* CoolSword: Two. A dao that he can control telekinetically, and one that can split its blade into a tuning fork to make other weapons vibrate until they explode. [[spoiler: After being killed, Jack takes the latter for himself.]]
* {{Expy}}: Android, skull like head, Aku's top assassin, and has a thing for jazz music? Sounds alot like X9.
* FaceDeathWithDignity: Downplayed. He's clearly terrified of his incoming death at Jack's hands, but his final words are a resigned "That's all, babe."
* FauxAffablyEvil: He chats quite amiably with Jack... and he also slaughtered an entire village just to draw Jack out.
* GenreSavvy: Quickly realizes that Jack doesn't have his sword, and then (correctly) assumes that Jack must have lost it. After that, the first thing he does is try to inform Aku about this. He also attacks a town and burns it down, knowing it would lure Jack to him. It took longer than he expected, but it turned out to work.
** He assumed he was going to face Jack's sword, so his fighting style involved using a rock golem and flying rocks to keep his distance between him and Jack. When his magic flute was destroyed, he still could use his voice to control his sword and keep fighting Jack at a safe distance, and even then he still had a special dagger that could shatter swords on contact as a final resource against Jack's mighty sword.
* HalfTheManHeUsedToBe: Jack destroys him by slicing him in two.
* HoistByHisOwnPetard: Jack uses his tuning fork sword against him by letting him use it on one of his knives...then throwing it in his face right as it explodes. He then proceeds to bisect him with his own sword.
* IncomingHam: "SAH-MUH-RAI JAAAAAAAACK!"
* KilledToUpholdTheMasquerade: Once he found out Jack lost his sword, there was no way Jack could let him live.
* KnifeNut: Uses both conventional ones and an odd combination of a butterfly knife and tuning fork.
* KnowWhenToFoldEm: After Jack uses his tuning fork sword against him, damaging him badly in the process, he realizes he's beat. Unfortunately for him, Jack quickly finishes him off before he can act on it.
* LargeHam: He goads and taunts Jack while boasting of his own skills. Jack is clearly ''not'' amused.
* LaughablyEvil: He's rather goofy and hammy for a mass murderer; personality traits that he shares with his boss Aku.
* MeaningfulName: Named after the [[https://en.wikipedia.org/wiki/Scaramouche stock play role]] to emphasize his nature as a comical braggart.
* MindOverMatter: He basically uses telekinesis to manipulate rocks to form a {{golem}}, or to move around his knives and swords.
* MoreTeethThanTheOsmondFamily: As the above picture shows, he's got a big grin full of the ol' pearly whites, despite probably not actually needing them for eating given he's a robot.
* MusicalAssassin: He uses flute that can animate rock and cause it to fight like a giant {{golem}}. On top of that, his singing can control one of his swords, and another one of his sword acts as a tuning fork that can make Jack's weapons explode ([[MegaManning which Jack takes for his own use after destroying him]]).
* NiceHat: Wears a conical straw hat, much like the type Jack had in previous seasons.
* NoCelebritiesWereHarmed: He is clearly inspired by Creator/SammyDavisJr, right down to his speaking mannerisms, vocal range, and verbal scatting.
* OhCrap: When Jack throws his about-to-explode knife in his face.
* OneManArmy: Destroys an entire settlement by himself, no {{Mook}}s required.
* OverdrawnAtTheBloodBank: After Jack slices him in two, a massive amount of black oil sprays out the side of his body (continuing the series' proud tradition of censoring blood while still showing gratuitous amounts of its substitute).
* RapidFireFisticuffs: Is immediately subjected to this by Jack when Scaramouche calls Aku.
* RoboticPsychopath: An AxCrazy android who remorselessly slaughtered an entire village, just to drive Jack to him.
* SissyVillain: For one, he dresses in a purple dress-coat and high-heels, and constantly refers to Jack as "babe".
* SmallNameBigEgo: He boasts that he's "Aku's Favorite Assassin", which is likely a lie, as Aku has had ''much'' better minions in previous seasons, and doesn't even seem to recognize Scaramouche's phone number when called. (That said: it's possible that he was actually telling the truth in that he's Aku's ''current'' favorite assassin, given how Jack has eliminated most of his competition at one point or another.)
* VibroWeapon: His tuning fork sword doesn't vibrate to increase cutting power but it does audibly resonate with whatever it cuts until they violently explode. It takes out a large chunk of a stone pillar.
* WarmUpBoss: The first villain this season to be a significant threat to Jack.

[[folder:"The Horseman"]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/horseman.jpg]]

A mysterious figure who haunts Jack's mind. He and Jack apparently met at one point, and seems to have delivered a major blow to Jack's sanity.

* BladeOnAStick: His main weapon, as a warrior on horseback, is a lance / spear.
* CoolHelmet: Wears a stylized armored helmet with a crown of antlers sticking out of it.
* TheDreaded: Whatever occurred between him and Jack is enough to make Jack scream in terror at the sight of him.
* GlowingEyesOfDoom: A harbinger of Jack's despair, with glowing yellow eyes.
* KnightOfCerebus: Shares this spot with the High Priestess. Let's just say that his scenes are ''terrifying''.
* MysteriousStranger: Nobody knows who or what it is, only that it... ''watches.''
* MultiMeleeMaster: Is equipped with at least long double ended spear and two swords.
* SicklyGreenGlow: The Horseman's stands against a backdrop of foggy green light, as he's usually accompanied by visions of the rotting corpses of those Jack believes he failed to protect.
* SinisterSilhouettes: He first appears as a nothing but a black silhouette, with only his glowing yellow eyes standing out from the rest of his outline.

!!Comic Characters

[[folder:Soule the Seer]]

An elderly seer who resides in a scorching desert. He sent Jack on to find the Rope of Eons to return to the past. Later, he would use Jack's sword in ritual to try and send Jack back, but his ailing body couldn't handle it and the ritual's failure caused the sword to be destroyed right before he died.

* CoolOldGuy: A helpful seer.
* HeroicSacrifice: [[spoiler:He knew that the ritual will kill him regardless of whether or not it succeeded, and did not inform Jack of this for fear of Jack backing down for the sake of his health.]]
* ISenseADisturbanceInTheForce: Reality was altered when Aku sent Jack to the future and Soule has felt the universe's misalignment in his bones all his life.
* IncurableCoughOfDeath: During his last appearance, he's showing symptoms of this, and [[spoiler: is dead by the end of the chapter.]]
* [[{{Seers}} Seer]]: He has intimate knowledge of mystical objects and rituals and can show visions of past events using smoke.

This page focuses on characters from the original seasons. For characters in [[WesternAnimation/SamuraiJack2017 Season 5]], go [[Characters/SamuraiJack2017 here.]]

* 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. As of Season 5 however, Jack plays this trope very, ''very'' straight, due to the series becoming DarkerAndEdgier and premiering on Creator/AdultSwim's Toonami block.

** 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.

* TheCoatsAreOff: The ClothingDamage 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.

* OOCIsSeriousBusiness: 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 has him using guns, bombs, and even a motorcycle. It's a pretty good indicator of just how BAD things have gotten.

A rave DJ whose magical rhythm hypnotizes the children of a town Jack passes through.

-->'''Aku''' ''(on the phone):'' I ''think'' I'm in the computer... Oh! Yes, Extra thick. ''(Evil Laugh)'' Yes! Thirty minutes or it's free!

* DystopiaJustifiesTheMeans: Subverted. The entire world ''could'' be reduced to uniform misery and despair, but he'd rather it present some occasional beauty, hope, and peace... [[DoubleSubverted so that he can ''crush it like a bug.'']]

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.

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.

* CoolHelmet: Wore one in the pilot.

* BreakoutCharacter: His popularity, along with being one of the only people capable of matching Jack, brought him back for three encore episodes.

** Any money he acquires in his journeys is probably spent on replacement robes.

* CharlesAtlasSuperpower: He does many astounding, even 'impossible' things, all as a result of his training.

* FishOutOfTemporalWater: 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 [[https://www.youtube.com/watch?v=VSrv_n4tw7w&t=3s trailer]] riding a CoolBike and using guns.

* OOCIsSeriousBusiness: 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.

* CombatPragmatist: Seems to have become this by Season 5, which is in stark contrast to his HonorBeforeReason 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 BadFuture for decades.
