History HateSink / YuGiOh

** Keith Howard, more commonly called Bandit Keith, qualifies for this trope. To wit, he has his goons kidnap Jonouchi (Joey) to duel Ghost (Bonz), traps our heroes in the same cave the duel took place, steals Jonouchi's entry card, and cheated in their duel in the Duelist Kingdom finals. His thuggish SmugSnake personality serves as a [[{{Foil}} counterpoint]] to BigBad Maximillion Pegasus' cultured MagnificentBastard, and accordingly it's Pegasus who gets to serve LaserGuidedKarma to Keith, flat-out killing him in the manga and quite literally ejecting him from the tournament in the anime.

** In contrast to the BigBad of the Battle City arc, that is both incarnations of Marik, their father has absolutely no redeemable qualities that make him likeable or sympathetic like the normal Marik nor is he entertaining to watch like Yami Marik; instead, he is shown to be a completely {{Abusive Parent|s}} who sees protecting the Pharaoh's memories as more important than the well-being of his children or his wife to the point that he is willing to put Marik through intense pain during the Tombkeeper's Initiation against his will, treating his adopted brother Rishid as nothing more than a servant. As a result, [[AssholeVictim nobody was sorry to see him go when]] [[KickTheSonOfABitch Yami Marik stabbed him to death with the Millennium Rod]].

** [[TheRival Jun Manjoume]]'s eldest brothers, who do not feel any bit of sympathy or attachment towards their sibling. The only thing that they need him for is for winning, to avoid besmirching their precious family name. It's really cathartic when Judai defends his rival after the brothers berate him for losing.

** Placido. During his duel with Yusei, he casually summons a thunderstorm and throws lightning and tornadoes around a heavily populated city for [=LOLs=]. When the sheer scope of the destruction is actually shown, you can't help but wonder how many lives the bastard took, and unlike the Dark Signers, there is no reset button in sight.

** Takasu is a [[WardensAreEvil corrupt warden]] who sadistically abuses the inmates in the Detention Center, confiscating their decks as well as lying and cheating to get his way. Rex Godwin orders him to observe Yusei's Mark of the Signers when he is arrested and sent to the Detention Center, but Takasu goes out of his to make things as unfair to Yusei as possible, challenging the latter to a duel despite his deck being confiscated, inflicting ElectricTorture on Yusei whenever he loses Life Points ([[DirtyCoward while ensuring he doesn't get the same treatment]]), and having his men use the security cameras to look at the cards in Yusei's hand.

** Insector Haga (Weevil Underwood) is even worse. He was the one that threw Yugi's Exodia cards off the deck of the cruise ship on the way to Duelist Kingdom, after all. In his duel against Yugi in Duelist Kingdom he manipulated Yugi into dueling in an arena that gave him an advantage (and still lost); he flat-out ''cheated'' in his duel in Battle City (and still lost); and in the Doma FillerArc, the moment where he pretends to rip Yugi's soul card in half to torment the poor Pharaoh (and then mocks him for his subsequent breakdown) is one of the most despicable moments of any character in the franchise.

* The anime-only Doma arc featured a BigBad named Dartz, formerly the king of Atlantis. While at first he was obeying the stones of Orichalcos in hopes of saving his civilization, being told to summon the Great Leviathan that could destroy the world and re-create it free of the corruption that had swept Atlantis, Dartz soon fully embraced the stones corrupting influence and led his civilization to it's destruction instead. Leading an army of undead beastial warriors, he fought against the three guardian dragons in the battle that led to Atlantis' sinking. He also gave the dragon Timaeus it's scar, and he's also implied to have killed his own father and daughter. Living for centuries under the influence of Orichalchos, Dartz grew to resent the entire planet and see human beings as wicked beings in need of eradication. Now completely far gone from his well-intentioned roots, he plotted to revive the Great Leviathan in order to raze the world and wipe out humanity, after which he could create a new world order where he'd have control of the souls of all that lived. Human souls were also required to revive the Leviathan, so Dartz started harvesting souls as he worked on his Evil Plan for 10,000 years. Aside from mass soul stealing, his crimes included corrupting players of Duel Monsters with the Seal of Orichalcos so that their souls were susceptible to being taken away, war profiteering under the guise of Gozaburo Kaiba and causing the deaths of several innocent casualties including Alaister's little brother (all so that Alaister could join him), sinking a ship full of people including Raphael's family (so that Raphael could join him), burning down a nunnery and killing everyone inside including Valon's caretakers (so that Valon could join him), many attempts at murdering Yugi and his friends, and sacrificing his own self to merge with the Leviathan and complete his efforts that put the entire world at great risk. While his soul ended up cleansed and redeemed after he and the Leviathan are destroyed, Dartz was shown to be hopelessly lost in his self-righteous delusions and malice while he was alive. He was such a monster that he could only ever find any sort of redemption after he was already dead.
