History Monster / YuGiOh

* [[SmugSnake Divine]], known as Sayer in the dub, 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 Lola/Toby Tredwell, was unable to withstand the procedure meant to test his abilities. Believing him to be weak and useless, Divine ordered [[ElectricTorture the intensity of the electric shocks to be amplified]], [[WouldHurtAChild causing the young boy's death]]. He also does his best to keep his prized Duelist Aki Izayoi 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 Luca, Lua, Yanagi and Jin Himuro when they come to him for aid against the Dark Singers. Then he threatens Lua's life in a Psychic Duel to test if he has powers like his twin sister Luca. Later that day he has another Psychic Duel with and murders Carly Nagisa 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 Mikage Sagiri. Divine 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 Aki.
* [[DragonInChief Lotten]], known as Lawton in the dub, is a tyrant lording over a small western style town called Crash Town, where he 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, Kyosuke Kiryu, West and Nico that results in a cave-in; Yusei and Kiryu fall off the mountain, while Nico and West are unconscious on the ground. Lotten takes them back to Crash Town, renaming it Lotten Town after Barbara and he [[TheStarscream double-cross his brother Malcolm]]. Later, not satisfied with the number of workers in the mines, he and Barbara begin forcing their henchmen to Duel for their survival, which is stopped by Yusei and Kiryu. Once he does start to lose his 2-on-1-handicap match against Yusei and Kiryu, he quits the Duel and tries to run away, but not before [[DirtyCoward he abandons Barbara to her fate and sets off explosives in the town]].

* [[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 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, 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.

-->--'''Yami Bakura''', while possessing the real Bakura, to Yami Yugi, [[Anime/YuGiOh Anime Series]], "[[Recap.YuGiOhAnimeS1E13EvilSpiritOfTheRing Evil Spirit of the Ring]]"

* [[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.

** Anime: The Spirit of the Ring was [[DemonicPossession possessing]] hero Yugi's friend Bakura Ryou for almost the entire duration of the series. During the Duelist Kingdom arc, he traps Yugi Muto and his friends within the card game, resulting in them being sent the graveyard if defeated. He subsequently tries to kidnap Mokuba Kaiba, and [[EyeScream rips Maximillian Pegasus's Millennium Eye out of his eye socket]], leaving him in a coma. During Battle City, he infiltrates the tournament and kills Bonz, Zygor, and Sid before trying to do the same to Yugi and Yami. Failing, he returns in season 5 as the BigBad. 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 Seto Kaiba into a Shadow Game, then traps Yami in the Memory World, possessing his own past self, Thief King Bakura, in the process. Eventually possessing Tristan Taylor as well and 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 Shadow Game in the present, with the intent of unleashing the apocalypse upon the world.

* ''[[VideoGame/YuGiOhTheFalseboundKingdom The Falsebound Kingdom]]'': [[MadScientist Scott Irvine]] traps Yugi, his friends, and the Kaiba brothers in a [[TheMostDangerousVideoGame multiplayer RTS game]] in an attempt to feed their souls to [=DarkNite=], a wicked spirit, who will then TakeOverTheWorld. When the virtual villain Emperor Haysheen is defeated, Scott deletes him from the game and assumes his position, brainwashing Yugi's friends into attacking him or attempting to kill everyone in the game; if the player fails to free Tea or Joey, everyone is destroyed or Scott forces Joey to kill himself, gloating all the while. He additionally steals Mokuba's soul to blackmail Kaiba into fighting Yugi, adding that he'd [[WouldHurtAChild kill Mokuba]] if Seto doesn't do as he says. When the heroes finally reach him, Scott reveals his plan and attempts to tribute their souls, and succeeds in killing everyone should the player fail. He also deletes other sapient [=NPCs=] from the game, and a prequel campaign reveals he was toying with an NPC version of Marik by manipulating him and making false promises of power. Cruel, merciless, and arrogant, Scott does everything in his power to achieve his goals and [[ItsAllAboutMe cares nothing for anything else]].

** 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 sapient, 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 SplitPersonality 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, 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 psychotic CombatSadomasochist with [[OmnicidalManiac omnicidal designs on the cast and/or world]], Dark Marik left the cast in shellshock.

* [[EvilOverlord Brron, Mad King of Dark World]], from season 3, is demented and sadistic, 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 [[POWCamp 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 [[HeroKiller 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, spitefully mocked Jaden by saying that he would never see his friends again.

* ''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.

* [[TheChessmaster The Spirit]] of the [[SoulJar Millennium Ring]], known as [[BigBad Dark Bakura]] ([[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 (though 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.

* [[SuperpoweredEvilSide Dark Marik (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: Anime/YuGiOhGX]]''
* Brron, Mad King of Dark World, is 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.

* Divine/Sayer 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 the intensity of the electric shocks to be amplified, which caused 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 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, kick-starting 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.
* Lotten/Lawton 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 cave-in. When it explodes, 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 he abandons Barb to her fate and set off explosives in the town.

* ''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.

* [[TheChessmaster The Spirit]] of the [[SoulJar Millennium Ring]], known as [[BigBad Dark Bakura]] ([[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.

''Franchise/YuGiOh'' has several [[CompleteMonster especially heinous]] villains.

* [[TheChessmaster The Spirit of the]] [[SoulJar Millenium Ring]], known as [[BigBad Dark Bakura (Yami Bakura)]], was the show's longest running antagonist, and one of its worst, [[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 rips Pegasus' Millenium 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 Shadowgame, 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.
