History Characters / YuYuHakushoMainVillains

* EvilCounterpart: To Yusuke; whereas Sensui is Yusuke's exact opposite, Toguro is more what Yusuke would become if he decided to abandon his good tendencies and love for his TrueCompanions and gave in to his inner BloodKnight. Even his coat is olive green, a darker shade to Yusuke's usual outfit. Not to mention they also share a DeadpanSnarker trait. Yusuke also acknowledges this during their final battle, noting that he found himself respecting Toguro for his strength and wanting to be like him.

* LightningBruiser: Unlike most beings of his stature, Toguro is every bit as fast as he is strong and muscular, even at his maximum level. He can easily speed blitz his enemies but mainly just tanks their attacks to show they cannot harm him.

* NormalFishInATinyPond: As powerful as Toguro is by the standards of the human world, he's considered only above average by the standards of Demon World's major fighters. Unfortunately for him, neither he or any other demon powerful enough to challege him could get past the barrier between the worlds, so he was left in complete boredom. He joined Sakyo because his plans would create a portal large enough to allow him passage to Demon World in hopes of finding a real challenge again.

* PersonOfMassDestruction: Though nothing is totally concrete, Sensui as well as Koenma have implied that S-Class-level fighters can wreck entire planets. Very likely the reason why no S-Classes ever fought on Earth at full power. And guess what, Sensui was the weakest one. Sensui himself claims that he would only use about half of his true power as any more would start wrecking the Human World with various disasters.

* SerialEscalation: He can manipulate an energy ball that he uses in various, deadly ways, [[spoiler: has seven personalities, each with a deadlier power]], which is good for a ClimaxBoss, but reaches ridiculous levels of power with Sacred Energy, which can level the planet with its mere presence and shape itself into various kinds of armor.

* WorldsStrongestMan: Sensui is the strongest human in the setting and one of the strongest beings ''period'', by his own admittance holding back out of a belief his true power alone would devastate the planet upon being released. He managed to defeat all of the heroes with ease while still holding back his true power, killed Yusuke, and when Yusuke came back stronger, Sensui was ''still'' winning the fight. His defeat only came because Raizen took over Yusuke and powered him up, and even then, Sensui didn't bother to dodge the final attack. He also was already slowly dying due to illness, meaning he was not as strong as he could have been.

* VillainousGlutton: Gonzo Tarukane is fat, ugly, and has a satisfying death scene.

* {{Gonk}}: Discussed in this exchange when the Heroes see an image of him for the first time.

* {{Sadist}}: He's not as blatant about it as Elder Toguro, but he's shown to greatly enjoy torturing Yukina far beyond just making money off her.

* UnwittingInstigatorOfDoom: His founding of the Black Book Club ends up having far reaching consequences. Not only does it enable Sakyo's rise to power, which ends up leading directly to Tarukane's death, but Sensui's {{Start of Darkness}} was kickstarted by seeing the BBC torture several demons to death. The end result is several deaths of both humans and demons alike, including himself and the entire BBC, and the world almost being overrun by demons ''twice'' thanks to Sakyo and Sensui's separate plans to open a portal to the demon world.

* UnskilledButStrong: Doctor is able to fight in close quarters with Yusuke post-Dark Tournament arc, and even found him, by using his territory to adjust his bodies make up to give himself more speed and power, as well as reducing his sense of pain. However, he's not actually a fighter, meaning whenever Yusuke and him directly fight head on, Yusuke almost always overpowers him quickly, forcing Kamiya to retreat and avoid a head on fight when possible. Yusuke even nearly outright kills him after deciding to get serious.

* AssholeVictim: Thanks Sakyo and Toguro for giving him what he deserved. Even the other Black Book Club members don't care about his demise and even mocked him shortly before his death, in contrast to their horrified and pissed reactions to finding out about Butajiri's demise.

* GutturalGrowler: His voice in the English dub is very snarly and deep, fitting his vicious personality.

* BigBadWannabe: While he is dangerous thanks to his wealth and his connections (being the founder of the Black Book Club, and hiring various demons and humans to do his dirty work), he overestimates his chances of winning, loses everything when Younger Toguro is defeated, and doesn't compare well to most of the antagonists in the series. [[spoiler: It doesn't help that The Toguro Bros were actually working for the real Big Bad, who had caused him to lose his money, and that they end up killing him after this is revealed.]]

* CruelMercy: Hiei spares his life at Yukina's request, but only after beating him to a bloody pulp and leaving him dirt poor with no money or any way of gaining it. He's eventually put down like a dog by Toguro under Sakyo's orders as a mere after thought.

* BigBadWannabe: While he is dangerous thanks to his wealth and his connections (being the founder of the Black Black Club, and hiring various demons and humans to do his dirty work), he overestimates his chances of winning, loses everything when Younger Toguro is defeated, and doesn't compare well to most of the antagonists in the series. [[spoiler: It doesn't help that The Toguro Bros were actually working for the real Big Bad, who had caused him to lose his money, and that they end up killing him after this is revealed.]]

* HateSink: Tarukane is easily one of the most hateable antagonists in the series, due to being a cruel bastard who tortures Yukina for her pearl tears despite ''already being filthy rich'', and being [[SmugSnake an annoying and overconfident asshole]]. The anime's english dub even further adds to this by having him be the founder of the Black Black Club and thus being both being directly and indirectly responsible for the terrible atrocities that group has committed. His death is brutal but very well-earned.

* {{Jerkass}}: Is a greedy and selfish asshole who cares about no one but himself and tortures demons for profit. He's also a massive prick to everyone except for the Toguro Brothers, and he attempts to trick his fellow Black Black Club members into betting money on a partially rigged match.

* VillainousLegacy: Though he isn't around for long and only appears in the Spirit Detective Saga for a few chapters/episodes, his actions via the founding of the Black Black Club and its [[SlaveryIsASpecialKindOfEvil Demon trafficking operation]] puts into motion much of the series and also leads Sensui to believe that [[HumansAreTheRealMonsters Humans must be destroyed]].

* Fiction500: He is able to stake the equivalent of ''Japan's entire national budget'' like it was ''pocket change'' when betting on the victory of Yusuke and Kuwabara over the Toguro brothers with Torukane Gonzo... [[spoiler: but then again, he KNEW Toguro would throw the fight for him and more importantly LIVE to report it.]] The dub ups the ante by keeping the figure 66 trillion+, but implying that it's US dollars, as opposed to Japanese Yen, which increased the figure by two orders of magnitude to more than the annual economic output of the entire planet (noted by two members of the Black Black group: one says, "That's more than Japan's Gross National Product," and another adds, "It's more than any nation's product").

* KnightOfCerebus: The Sensui Seven mark one of the darkest turns in the series. While there have been innocent humans threatened before, the only on-screen deaths (other than Yusuke's in the opener) were the members of the [[AssholeVictim Black Black Club]] at the hands of Toguro. Even with Sakyo we never actually see his death as he's BuriedAlive as the Dark Tournament stadium collapses around him. However Doctor [[spoiler:murders several doctors and mutilates a nurse on screen, while nearly killing an entire hospital]] and Gourmet [[spoiler:''eats'' Murota. ''[[{{Squick}} on screen]]'']]. [[spoiler:To say nothing of how Shinobu outright manipulates Yusuke and his friends into nearly killing Doctor had it not been for Genkai resuscitating him, and ''actually'' killing Sniper and Gamemaster, the latter of whom ''is an 11-year-old boy''.]]

* BloodBathVillainOrigin: To be fair, the [[AssholeVictim Black Black Club deserved it]].

* DrivenToVillainy: Thanks to that [[HumansAreTheRealMonsters damn Black Black Club]], though it's also kind of his own fault as well. Sensui's [[BlackAndWhiteInsanity inability to accept morality outside of absolutes]] is what made him unstable; if his ideals hadn't been coiled so tightly in his head to begin with, he wouldn't have snapped like he did in the first place.

* TheJuggernaut: Spends the majority of his screentime being utterly implacable by even the strongest of fighters. Even Yusuke during the final round of the tournament is thoroughly outclassed during most of the fight despite two power-ups, though the third finally pushes him to Toguro's level. Besides Sensui and the foes faced during the final arc, Toguro is one of the single strongest beings in the story. For Yusuke to win, he had to train and be given Genkai's powers and even that was just barely enough.

* {{Jerkass}}: He's smug, rude and loves mocking others, and though he's usually more childish than nasty he does still do and say some dickish things to people just because he thinks he's better than them (Seaman being a good example). This is ultimately shown to be the result of ignorance rather than malice, however.

* SevenDeadlySins: As one of the Sensui Seven, he represents {{Sloth}}.

* VillainousBreakdown: Kurama [[spoiler: reveals that he is going to die]] [[ShootTheDog in order to invoke one of these in him and unnerve him enough to cause him to lose the game]]. It works, and it's heartbreaking.

Karasu is a Quest class demon. He is able to use his aura to create bombs undetectable by lower-level demons, as well as create bombs within his victims. He wears a mask over his mouth which restricts his unstable powers. He is also able to use his entire body as an explosive. [[DepravedHomosexual He takes quite a liking to Kurama.]]

* SmugSuper: Constantly gloats about his superiority over his enemies, how pitiful and flawed they are, and how futile their attempts to stop him from murdering them are -- like a cat playing with a caught mouse. Even when he faces off against an opponent who far outstrips him, he retains his smug sense of superiority until forced to abandon it. As a result, he actually managed to [[spoiler: overcome Yoko Kurama, who effortlessly killed an S-Class demon later on, to the point where he reverts back to his human form, albeit very weakened]], so his overconfidence is not unjustified. However, that very overconfidence [[spoiler: proves to be his downfall, when he ignores the results of a seemingly failed attack by Kurama, then assumes he too weak to pose a threat or possibly have a plan that could harm him]]. Despite this, Karasu is still extremely powerful and intelligent; he came much closer to killing Kurama than any other enemy, and technically won Team Toguro's [[spoiler: ''only'' ]]victory.

** [[spoiler: He becomes so composed when he loses his mask, being more prone to actively sadistic moments]].

* BecameTheirOwnAntithesis: Half a century ago, Younger Toguro (along with his weaker older brother) was a fellow student of Genkai's martial arts school devoted to protecting humanity and ''hunting down'' demons. Driven mad with grief at the loss of his students, he became the very demon that he devoted his life as a human to destroy.

* BecomeTheirOwnAntithesis: Half a century ago, Younger Toguro (along with his weaker older brother) was a fellow student of Genkai's martial arts school devoted to protecting humanity and ''hunting down'' demons. Driven mad with grief at the loss of his students, he became the very demon that he devoted his life as a human to destroy.

* HanicappedBadass: As is revealed near the end, Sensui was suffering from [[spoiler: incurable cancer]]. [[spoiler: In spite of this, he's the most powerful human]] up until his death.

* BigBadDuumvirate: He forms this with Younger Toguro. However Younger Toguro is far more dangerous than him and is more involved with Team Urameshi.

* VisionaryVillain: Averted in the manga, but his portrayal in the anime invokes this. See ForTheEvulz above for details.

* EvenEvilHasStandards: Even he still finds some actions completely distasteful, especially those of his older brother. Notably, he becomes exceptionally irate whenever Elder Toguro mocks Genkai. He also ''despises'' cowards.

* EvenEvilHasStandards: It is a poor taste for a gambler to cheat, and Sakyo [[TranquilFury does NOT tolerate poor taste]] gracefully. He's also noticeably disapproving of Elder Toguro's cruelty, though more because of [[StupidEvil how pointless it is.]]
