* AlternativeCharacterInterpretation:
** Is Mugen's and Fuu's bickering BelligerentSexualTension or just companions getting on each other's nerves?
** Sara: unfortunate AntiVillain or boring, overpowered VillainSue?
** Also Kohza, whose exact motives aren't revealed. Money, companionship, both? Or was she just confused?
* SugarWiki/AwesomeMusic: With Nujabes' involvement in the soundtrack, it's no surprise. There's also the haunting song that Sara sings as part of her traveling performer act, and the one by Ikue Asazaki that plays over Mugen's flashbacks to his youth with Koza and Mukuro.
* BizarroEpisode:
** The zombie episode ("Cosmic Collisions"). It starts off with Jin and Mugen eating rare mushrooms, and ends with [[spoiler:a nuclear explosion and the villain leaping out of his grave]], and it is ''never mentioned again.'' The operative word here is {{mushroom|Samba}}.
** The Baseball episode ("Baseball Blues"), as the bizarre plot involves the gang playing baseball against a bunch of Americans intending to invade.
** Episode 9 ("Beatbox Bandits"), at least towards the end, where the conflict is resolved... by a burning field of weed, which gets the anatagonists all chummy with each other while completely forgetting about whatever they were supposed to do.
*** To be fair, it ''is'' a burning field of weed. The fumes probably made half the prefecture high.
* CompleteMonster: The bloodthirsty pirate Mukuro raided a ship for gold, while ordering all of the sailors aboard murdered. [[TheCorrupter Corrupting Mugen]] into becoming hired muscle, Mukuro later abandons Mugen on a cargo ship after he himself makes off with the goods. Slaughtering an entire village with his gang, Mukuro keeps the young men alive to use in the raid of a gold-bearing government vessel. During the raid, Mukuro uses his followers as CannonFodder for his trap, before trying to use explosives to kill [[BadBoss friend]] and foe alike, [[{{Greed}} just so he can keep all the gold]]. Even his own family is not safe from Mukuro, who [[{{Matricide}} killed his mother]] and constantly abuses his sister.
* CrazyAwesome: Mugen's nonsensical style of fighting works perfectly for him, and is pretty damn impressive to watch.
* EarWorm: Several. Nujabes' "battlecry" (the opening theme), MINMI's "Shiki no Uta" (the closing theme), tsutchie's "pretending to…" and "sincerely", Nujabes' "mystline" and FORCE OF NATURE's "vagrancy" are some select choices. Nujabes' "Counting Stars", which concludes "Gamblers and Gallantry", appears only on a compilation for his record label and not on the soundtracks, making it one of the most sought after songs of the show. Many ''Champloo'' fans have even stated that they thought the worst of hip hop music before this series came along and changed their minds about the entire genre.
* EnsembleDarkhorse: Several characters are quite popular despite their brief appearances and are prone to crop up in fanfiction. This includes Sara (due to her intense arc), Yatsuha (due to her hilarious appearance and manipulation of Mugen, whom she's shipped with), Yukimaru (a significant figure from Jin's life, also often shipped), and Shino (due bringing out Jin's softer and more romantic side in her bittersweet appearance, again frequently shipped).
* EvilIsSexy: Hotaru, a very attractive antagonist who successfully gets Mugen's attention and nearly manages to poison him by seducing him.
* FandomBerserkButton: "Hey guys, who would win in a fight, Mugen or Jin?" Cue intense arguments all around.
* HilariousInHindsight: In a world full of dangerous swordfighters, Fuu is... decidedly not one of them. A little over a year later, however, her [[Creator/AyakoKawasumi voice actor]] would go on to play [[VisualNovel/FateStayNight one of the most famous swordswomen in all of anime]].
%%* HollywoodHomely: Shino and Yuri.
* HoYay:
** Actually played straight (no pun intended) by the Dutchman, who comes from a sect that believes enlightenment can be obtained through homosexuality.
** The Jin/Yukimaru subtext. Even though Jin has sex with women on multiple occasions and actually falls in love with a sex worker in one episode, he appears to be emotionally affected by Yukimaru's reappearance, who is essentially upset because Jin didn't take him with him. Given the Edo period's lax attitude towards bisexuality, it's entirely possible that they were, in fact, lovers.
** Mugen and Jin, bordering on FoeYay. One such example is the very first episode, when Mugen dreams of Jin being naked in a bathtub during their fight, and he doesn't fail to point out "his dong hanging out" when he recalls the dream to him.
* IronWoobie: Mugen. The "Misguided Miscreants" two-parter revealing his backstory gives him plenty of reasons to feel sorry for himself, on top of being betrayed by his childhood friend/possible love interest and nearly dying. But at any point does he let it get him down? No. He lets it make him ''[[RoaringRampageOfRevenge angry]]''. The man simply does not give a fuck.
--> '''Mugen:''' "I don't give a rat's ass about going to hell. I guess it's because I feel like I'm already there."
* JerkassWoobie:
** Mugen, who is rude a good chunk of the time. Despite that, he doesn't remember having any parents and appears to have lead a life of crime since young. In particular is him being once tricked into a life of piracy in the past by Mukuro who betrayed him.
** Fuu. As bossy as she may be, her mother died a year ago and [[spoiler:the two were abandoned by her father (aka the Sunflower Samurai), hence why she's so desperate to find him]]. And by the end of the series, [[spoiler:said father's sick, revealed to have left in order to save his family from Christian persecution, and dies at the hands of Kariya]], leaving Fuu overwhelmed.
* MoralEventHorizon: Umanosuke chased down Fuu, [[spoiler:molested her, knocked her out, then [[RuleOfSymbolism tied her to a cross]] and beat her in the semi-final episode]].
* NightmareFuel:
** The zombie episode, especially the [[https://www.youtube.com/watch?feature=player_detailpage&v=kFy8AiSEPX0#t=1378 credit ending]] which includes a JumpScare.
** The way the counterfeiter was going to torture the secret police in Episode 15 ("Bogus Booty"). It involved molten gold and a funnel. TruthInTelevision in case you were wondering.
*** Hell, Bogus Booty starts out pretty nightmarish too, panning in on [[TheLostWoods a dark, mist-shrouded forest]]. A young man, clearly terrified and running for his life, pursued by ninjas from what seem to be several different clans working in tandem. There’s no music, either tense or cheerful, and the ninjas [[AmbiguouslyHuman clearly aren’t all human]], especially the ones with [[GlowingEyesOfDoom yellow eyes]] and glowing red fingernails.
* NightmareRetardant: The zombie episode, while still frightening, loses a fair bit of its edge when you realize that they were most likely just having a [[MushroomSamba very, very bad trip]].
* OneTrueThreesome: The main three, due to their VitriolicBestBuds dynamic, especially with Fuu quite possibly having feelings for both guys, and Jin and Mugen admitting at the end that they consider each other their first friends.
* {{Reconstruction}}: There are those who see ''Samurai Champloo'' as a reconstruction of the JidaiGeki genre.
%%* TheScrappy: Kawara Sosuke
* StoicWoobie: The ever-so-stoic Jin, who killed his kendo master (his one parental figure) prior to the story.
* SugarWiki/SuperlativeDubbing: The English and French dubs have been very well received, the latter being considered the best French anime dub EVER, especially considering France's history of dubbing anime in general REALLY BADLY.
* UnintentionallyUnsympathetic: "Hellhounds for Hire" involves a yakuza gang trying to take over a town by cheating the residents at dice. While the gang is ObviouslyEvil, it's kind of hard to feel bad when all the residents know that they're cheating, and all they have to do to stop their take over is to NOT GAMBLE WITH THEM!
* WhatAnIdiot: Mugen gets called an idiot and a fool by many viewers for actually trusting Mukuro again.
