[[AC:[[Manga/YuGiOh Manga]] and [[Anime/YuGiOh Second Series Anime]]]]
* [[TheChessmaster The Spirit]] of the [[SoulJar Millennium Ring]], known as [[BigBad Dark Bakura]], or [[KillerGameMaster Yami Bakura]], was the [[OverarchingVillain longest running antagonist]] of the series, and one of its worst, though his actions between the manga and anime were different.
** In the manga, Dark Bakura was with [[NiceGuy Ryo]] [[SixthRanger Bakura]] for a long time before he moved to Domino City. Whenever any of Bakura's friends tried to play games with him, Dark Bakura would trap them inside of RPG figures, putting them into comas. When Yugi and his friends came over to play the Monster World RPG game that Bakura himself created, Dark Bakura trapped them inside over the course of the game and tried to kill them. After this, he fakes a HeelFaceTurn and gets the gang to believe that he's trying to help them--although they don't trust him-and then kills Pegasus and steals his Millennium Eye behind their backs. During Battle City, he stabs himself in the arm and then reverts back to normal Bakura so that Marik can gain the groups trust and then murders Ghost Kozuka after a Duel to take his Puzzle Card. In the final arc, Dark Bakura is revealed to have manipulate his host into constructing an RPG of Atem's final battle, in which the RPG figures are implied to be sentient, to summon Zorc Necrophades, who will then proceed to destroy the world, again if he wins the game against Dark Yugi. He Duels Jonouchi and Yugi at two separate occasions and nearly kills them both.
** In the anime, the Spirit of the Ring was [[DemonicPossession possessing]] [[TheHero Yugi's]] friend [[NiceGuy Bakura]] for almost the entire duration of the series. During the Duelist Kingdom arc he traps Yugi and his friends within the card game, resulting in their being sent the graveyard if defeated. He subsequently tries to bodyjack Mokuba Kaiba, and [[EyeScream rips Pegasus's Millennium Eye out of his eye socket]], leaving him in a coma. During Battle City, he infiltrates the tournament and sends Bonz, Zygor, and Sid to the Shadowrealm, then tries to do the same to Yugi and Yami. Failing, he returns in Season 5 as TheBigBad. Outing himself as an agent of [[GodOfEvil Zorc Necrophades]], The Spirit of the Ring repossesses Bakura, and sets in motion a plot to bring about TheEndOfTheWorldAsWeKnowIt. He kidnaps Mokuba to force Kaiba into a Shadow Game, then traps the cast in the Memory World, where he can control their lives, possessing Tristan and his own past self, Thief King Bakura, in the process. Eventually pulling a YouHaveOutlivedYourUsefulness on his own past self, The Spirit of the Ring unleashes Zorc in the past, while taking on Yami in his final Shadowgame in the present, with the intent of making the world bow down to his dark god.
* [[SuperpoweredEvilSide Dark Marik]], or [[SealedEvilInACan Yami Marik]], is the twisted split personality who drove the real Marik off the deep end in the first place. Seizing control of Marik's body during [[EnfanteTerrible his childhood]], he killed their [[AbusiveParents abusive father]], and then tried to kill their adoptive brother, who had [[SealedEvilInACan been keeping Dark Marik locked up]]. This failed, and Dark Marik bided his time, gaining strength, and driving Marik to further and further acts of cruelty in his quest to kill Yugi and/or TakeOverTheWorld including, but not limited to, kidnapping, MindRape, brainwashing, and attempted murder. Resurfacing when Marik's adopted brother was defeated in the Battle City semifinals, Dark Marik exiled his better half from their shared body, and then decided to personally screw with everyone for no reason. He engaged Mai Kujaku/Mai Valentine, the aforementioned Dark Bakura, and Katsutya Jonouchi/Joey Wheeler in a series of sadistic Shadowgames, with Mai experiencing imaginary but extremely painful wounds/losing memories whenever a monster was destroyed, the Bakura/Spirit of the Ring lost parts of his body, and Jonouchi/Joey felt extreme pain when a monster was destroyed/lost life energy. The games eventually saw Mai trapped in her own mind slowly dying, Bakura completely vanishing, and Jonouchi/Joey in a coma; in the dub, all three were sent to the Shadowrealm. He also made several attempts on the lives of his sister and comatose adoptive brother. This all culminated in a final battle against Dark Yugi/Yami, during which he arranged for any damage the two of them incurred to be suffered by their better halves, Marik and Yugi, nearly killing them both. An AxCrazy CombatSadomasochist with [[OmnicidalManiac omnicidal designs on the cast and/or world]], Dark Marik left the cast in shellshock.

''[[AC: YuGiOhGX]]''
* [[Anime/YuGiOhGX Anime]]: [[KnightOfCerebus Brron]], [[EvilOverlord Mad King of Dark World]], is [[AxCrazy demented]] and {{sadist}}ic, ruling the [[AnotherDimension Spirit World]] as its vile dictator and being responsible for its deplorable state and the oppression of its denizens. His [[TheDragon right-hand man]], Zure, oversaw Brron's will, detaining anyone who defied him in internment camps while killing Duelists who could be threats to him. The executions occurred at his fortress and involved releasing monsters at disarmed Duelists while Brron himself and his minions watched the spectacle. After learning of Jaden's presence in his domain, Brron orchestrated a plot that involved turning Jaden evil by sacrificing all of his friends one by one with his set of "Wicked Doctrine" cards to create the "Super Fusion" card. After his defeat, Brron, before dying, mocked Jaden by saying that he would never see his friends again before dying.
* [[Manga/YuGiOhGX Manga]]: [[BigBad Tragoedia]] was formerly a human from the village of Kul Ena. After the village was annihilated, Tragoedia was trialed by the malice inside of his heart, resulting into him becoming a ''ka'', or Egyptian Spirit Monster. After trying and failing to kill the priests, he's [[SealedEvilInACan sealed away for thousands of years]]. Once released, Tragoedia has his spirit either possess or corrupt Duelists to Duel others in pain-inducing shadow games where the loser will be [[AndIMustScream trapped in a dimension of darkness for eternity]]. Just [[ForTheEvulz for the sheer fun of Koyo being harmed by what he loves doing]], Tragoedia gives Koyou Hibiki a special punishment, where his life will slowly and painfully deplete with every passing Duel Koyo has. While [[DemonicPossession possessing Principal MacKenzie]], Tragoedia manipulates the American students into draining the energy of other students through Duels to restore his body, [[YouHaveOutlivedYourUsefulness only to drain their life energy when they've fulfilled their purpose.]] Once Judai/Jaden and Manjoume/Chazz confront him, he reveals that the only reason he sent hundreds of people into the dimension of darkness was [[ForTheEvulz to kill his boredom]], throwing away any possible sympathy for him about [[FreudianExcuse his village being massacred]]. He then Duels the two for the sole reason of seeing them in pain during their Shadow Duel. Willing to [[BadBoss inflict Penalty Games on his own minions]] if [[YouHaveFailedMe they fail him]], Tragoedia is a {{sadist}} who only takes pleasure in causing people suffering.

''[[AC: Anime/Yugioh5DS]]''
* [[BigBadWannabe Sayer]], known as Divine in the Japanese version, is the leader of a group of Duelists training to control and harness their psychic abilities in order to turn them into soldiers of war against the rest of humanity. His earliest Duelist, Toby Tredwell, was unable to withstand the procedure meant to test his abilities. Believing him to be weak and useless, Sayer ordered [[ElectricTorture the intensity of the electric shocks to be amplified]], causing the young boy's death. He also does his best to keep his prized Duelist Akiza secluded from anyone outside the Arcadia Movement to keep her full of hate and resentment at the world for his goals, as well as to hide his own secret motives. To this end, he gasses Luna, Leo, Yanagi and Bolt Tanner when they come to him for aid against the Dark Singers. Then he threatens Leo's life in a Psychic Duel to test if he has powers like his twin sister Luna. Later that day he has another Psychic Duel with and murders Carly Carmine by [[DestinationDefenestration sending her through a window]] with a direct attack, [[StartOfDarkness beginning her rebirth into a Dark Signer]]. He then returns from his DisneyDeath at the hands of Carly, posing as a security agent to attack Yusei and Mina. Sayer states that anybody who falls prey to him will simply follow his orders and nothing more, as he takes full advantage of that individual's weakness, just like he did with Akiza.
* [[{{Jerkass}} Lawton]], known as Lotten in the Japanese version, is a tyrant lording over a small western style town called Crash Town, who forces those he's defeated to join him or face slavery in the mines. He gets into a match with Yusei while Yusei and the gang are trying to escape the mines, but before it can be decided, he throws a stick of dynamite at Yusei, Kalin, West and Nico that results in a cave-in; Yusei and Kalin fall off the mountain, while Nico and West are unconscious on the ground. Lawton takes them back to Crash Town, renaming it Lawton Town after Barb and he [[TheStarscream double-cross his brother Malcolm]]. Later, not satisfied with the number of workers in the mines, he and Barb begin forcing their henchmen to Duel for their survival, which is stopped by Yusei and Kalin. Once he does start to lose his 2-on-1-handicap match against Yusei and Kalin, he quits the Duel and tries to run away, but not before [[DirtyCoward he abandons Barb to her fate and sets off explosives in the town]].

[[AC: ''Anime/YuGiOhArcV'' anime]]
* [[ControlFreak Jean-Michel Roger/Roget]], the ArcVillain of the Synchro Arc, is the director of Security for the Synchro Dimension. Originally a member of [[AcademyOfEvil Academia]], Roger betrays the academy and attempts to [[AmbitionIsEvil take over the Synchro Dimension for himself]]. He creates a device that allows him to brainwash the security force into mindless drones for his future attempt at [[TheStarscream overthrowing the executive council]], and conducts experiments on the [[AxCrazy dangerous]] criminal [[CombatSadomasochist Sergey]] to turn him into an even more aggressive cyborg, with intention of having him crush Jack Atlas, thereby crushing the hopes of Tops and Commons alike. When Selena duels Yugo, to ensure she wins, he repeatedly alters the track for Selena to get action cards instead of Yugo, not caring that it puts Yugo in danger of falling off the track and dying. Later on during Yuya's duel against Crow, he activates a chip he installed in Yuya's helmet, [[WouldHurtAChild painfully electrifying Yuya]] to force him into a more aggressive state, shrugging it off when told that Yuya could die from this. When his attempts to overthrow the council and dethrone Jack Atlas fail, he blows up the security headquarters, disables all elevators except for one he has himself and Yuzu take, [[BadBoss leaving his other subordinates to die]], and decides to take Yuzu to the fusion dimension in hopes that this will cause him to be forgiven by Academia. When Jack and Crow stop this from happening, [[TakingYouWithMe Roger attempts to open up a wormhole to suck himself and everybody in the city in it]], [[FateWorseThanDeath trapping them in dimensional limbo]] purely out of spite, telling everybody that [[ItsAllAboutMe if they won't obey him, everything in the world should disappear]].

* ''VideoGame/YuGiOhForbiddenMemories'': [[BigBad Heishin]] is an EvilChancellor and EvilSorcerer of Ancient Egypt. As soon as he gets the ancient power of the Millennium Items, he attacks the palace with his soldiers, killing various people, including the Pharaoh and his wife, and mortally wounding Simon Muran, the Prince's tutor. When the Prince tries to escape, he threatens to kill him if he doesn't give him the Millennium Puzzle. The Prince shatters it, and is transported inside of the puzzle to the present day. When he returns, he finds that Heishin has destroyed much of Egypt and Simon Muran has died from his injuries. After defeating Heishin's top mages, he finds Teana has been kidnapped and is having her life threatened in an attempt to lure the Prince into a trap to kill him, but this is stopped by Seto, Heishin's own henchman, who sets her free and ends up being TheStarscream. Heishin obtains the Millennium Puzzle and summons the Dark God, Darknite, and commands him to destroy the world and make him {{a god|Am I}}, to which Darknite responds by [[EvilIsNotAToy killing Heishin]]. Petty, selfish, and so obsessed with power that he'd attempt to murder underage teenagers in his pursuit of it, Heishin was a monstrous individual.
