History Characters / YuGiOhSupportingCharacters

* [[ArrogantKungFuGuy Arrogant Gamer Guy]]: In the manga.

Kaiba is a rival of Yugi Mutou and Dark Yugi. He's the head of the gaming company "Kaiba Corporation" and was first introduced as a prodigal, cold-hearted gamer who stopped at nothing to achieve his goals, even resorting to torturing or killing his opponents. Following his second battle with Yugi during his Death-T games (where he acted as a main antagonist), he was left in a coma, where he reconstructed his heart and emerged less evil. Since then, rather than a villain, he merely attempted to reclaim his title and challenge Yugi again - retaining his arrogance, but shares compassion for his younger brother, Mokuba. Basically, he's initially a FauxAffablyEvil SmugSnake before CharacterDevelopment changed him into a SmugSuper {{jerkass}} BreakoutCharacter with much more involvement with the plot as a anti-hero. Even though he's a supporting character, he appears with a lot of prominence in the second series anime adaptation - in manga canon, he has an ambition to destroy Kaiba Corporation's past as a weapons company under his father's ownership, and this subject takes up the majority of two FillerArc sagas of the second series anime and is a vital subplot of a third. He is the reincarnation of Seto, one of the Six Priests who protected the Pharaoh Atem, Yugi's past life, and his monster Blue Eyes, is the reincarnation of his lover, Kisara.

* AgentScully: In the dub, where his insisting that everything supernatural around them is some sort of trickery comes across as him trying to convince himself. In the original, Kaiba didn't disbelieve in magic, in fact his Dark Game with Yami Yugi was his inspiration to develop his virtual projectors. He just didn't have much interest in the magical chaos occurring around him because most of the time it wasn't his problem.

** BadassNormal: The most powerful Duelist in the series to lack a Millennium Item (the only other contender is Joey, and that's only [[AdaptationalWimp in the manga]]). His only losses in the manga were from wielders, his only losses in the anime were from Noah (who cheated) and Dartz ([[SNKBoss who basically cheated]]), and he's one of the few Duelists to beat an Item-wielder without being one himself.

* CharacterizationMarchesOn: Before he was the SmugSuper JerkAss we all know, he used to be FauxAffablyEvil, even more so during the Death-T saga. He obtained all of his Blue Eyes White Dragon cards through blackmail (possibly involving their owners committing suicide) and subjected Sugoroku (Yugi's grandfather) to realistic holograms which almost led to a heart attack. Along with his all-me personality, he was willing to kill his Yugi and his friends (and a baby) with his amusement park of death involving trained killing professionals and a known axe murderer, all because Yugi beat him in a card game and gave him a karmic Penalty Game, and was willing to give a Penalty Game to Mokuba for losing to Yugi. He gets better after his Mind Crush, though, to the point where he was disgusted by Marik's methods of having Yugi and Joey duel to the death and threatening to make Tea ingest a cyanide pill during Battle City, even though he used to be just as bad, and arguably worse.

** Maybe he's the reason why the anime makes it a point to make Joey less badass and take away Bakura's screentime from the manga. Perhaps the staff are Kaiba fans?

* KickTheDog: Does this a few times. Usually to Jonouchi. In the anime, exemplified by all those times they put him in a dog suit... (Joey, not Kaiba.)

* RedOniBlueOni: The blue to Joey (one of two) and Dark Yugi's red.
* RefugeInAudacity: Constantly pesters Joey during Battle City, especially during the four-way duel, for not being able to hold his own as a duelist (in spite of evidence to the contrary), and insists that he has to stand up on his own. Moments later during the latter, when Joey counters a move from Dark Marik, Kaiba interferes with one of his own cards, effectively helping Marik and screwing over Joey, with the former's monster surviving the battle after all. Of course, it's more likely than anything that Kaiba is either [[CombatPragmatist playing the entire field in order to ensure his opponent will be Yugi]], or he's just being a gigantic {{troll}} towards Jonouchi.

** During anime {{FillerArc}}s: When he tried to use it against Lector, it was destroyed, since Lector had assumed the appearance of Jinzo. During his duel with Willa Mette, Mette used a spell card to prevent Kaiba's Crush Card from activating. Thus, the only times Crush Card actually worked is in his duel with Joey and Alister, the first was an anime filler match and Joey ''still'' put up a good fight, and the second it only helped because he fused it with [[DeusExMachina Fang of Critias]], in the meantime Alister still stopped him from using it and it remained on the field useless. Given the consequences when it DOES go off though, it's understandable that people want to counter it so effectively.

He gets better after his Mind Crush, though, to the point where he was disgusted by Marik's methods of having Yugi and Jonouchi duel to the death and threatening to make Anzu ingest a cyanide pill during Battle City, even though he used to be just as bad, and arguably worse.

** Maybe he's the reason why the anime makes it a point to make Jonouchi less badass and take away Bakura's screentime from the manga. Perhaps the staff are Kaiba fans?

* FreudianExcuse: Adopted by an [[AbusiveParents abusive father]] who taught him that being a failure in anything, even losing games, means you don't deserve to live. Lost everything but his brother in unknown circumstances before that.
* FriendToAllChildren: Shockingly. Moukba explains the reason Seto works so hard for [=KaibaCorp=] is to achieve his dream of a Kaiba Land to bring happiness to children. N'aww.
* GoneHorriblyRight: Gouzaburo wanted Kaiba to be as ruthless as him, and view everyone as a possible threat. You have to wonder how he saw that working out, although he probably didn't expect Kaiba to oust him before leaving high school.

* ItsAllAboutMe: Because it's all about Seto Kaiba.

* KickTheDog: Does this a few times. Usually to Jonouchi. In the anime, exemplied by all those times they put him in a dog suit... (Jonouchi, not Kaiba.)
* [[KingOfGames King of Card Games]]: As previously stated, the story [[InformedAbility informs us]] of his powess in gaming which rivals Yugi (a straightforward KingOfGames), with his high scores on every arcade machine at the Domino Arcade, which are connected to every arcade machine in Japan. But even then, the game that he takes the most interest in and shows the most skill is ''Magic & Wizards''/''Duel Monsters'', in spirit of that game defining his introductory chapters of the manga.

* OrphanageOfFear: May not have been that bad, but he ''did'' feel compelled to win his way out in a game of chess (in the manga, he even cheated to do so). Odds were that the others weren't very friendly towards him or his brother.

* PerpetualFrowner: When he's not a SmugSmiler, which is an improvement to his StepfordSmiler and SlasherSmile he used to put on.

* RedOniBlueOni: The blue to Jounouchi (one of two) and Dark Yugi's red.
* RefugeInAudacity: Constantly pesters Jonouchi during Battle City, especially during the four-way duel, for not being able to hold his own as a duelist (in spite of evidence to the contrary), and insists that he has to stand up on his own. Moments later during the latter, when Jonouchi counters a move from Dark Marik, Kaiba interferes with one of his own cards, effectively helping Marik and screwing over Jonouchi, with the former's monster surviving the battle after all. Of course, it's more likely than anything that Kaiba is either [[CombatPragmatist playing the entire field in order to ensure his opponent will be Yugi]], or he's just being a gigantic {{troll}} towards Jonouchi.

* SelfMadeOrphan: Killed his adoptive father in the manga. In the anime Gozaburo manages to escape and makes a comeback as a FillerVillain...and is killed when Kaiba and the others leave him trapped in his self-destructing virtual world.

* TrashTalk: He seems to do this to a lot of people. Specifically, to those he particularly dislikes.
* TroubledButCute: He really wants to be more sociable, but due to his belief that "every single one of us is alone in this world", he's unable to do so. He also claims that he never needs help from anyone. A certain somebody must've planted all that in his head.

* UnstoppableRage: He really has no control over his rage when he's playing Duel Monsters, especially when he's facing off against Yugi. Often, this renders him vulnerable, since he's unable to think straight. And whenever someone tries to make him feel better, he doesn't pay any attention to ''anything'' anyone has to say.

* VillainousBSOD: Following the first episode of the Duel Monsters anime adaptation, after his defeat to Yugi he starts to question his motivations and goals as he realizes power alone isn't enough to beat him - enough for him to idiotically leave his company and his little brother unattended (in the manga, he was in a coma at the hands of Yugi's "Mind Crush" Penalty Game during Death-T).
* TheWorfEffect: His Shadow Game duel against Pegasus is to remind fans just how severely Pegasus' Millennium Eye rigs the match in his favor, turning Kaiba's moves against him left and right. The cast lampshades this in the English anime, noting Pegasus likely had them watch the duel as intimidation.

* {{Narcissist}}: In appearance only. In reality, creator Kazuki Takahashi claimed in an interview he presents this image to try and combat his severe self-hatred after Gozaburo's death.

** During anime ((FillerArc))s: When he tried to use it against Lector, it was destroyed, since Lector had assumed the appearance of Jinzo. During his duel with Willa Mette, Mette used a spell card to prevent Kaiba's Crush Card from activating. Thus, the only times Crush Card actually worked is in his duel with Joey and Alister, the first was an anime filler match and Joey ''still'' put up a good fight, and the second it only helped because he fused it with [[DeusExMachina Fang of Critias]], in the meantime Alister still stopped him from using it and it remained on the field useless. Given the consequences when it DOES go off though, it's understandable that people want to counter it so effectively.

* StrawNihilist: Especially in the manga, has a couple of Nietzsche-themed [[HannibalLecture lectures]] to anyone whom doesn't share his mentality and is seen reading Nietzsche's ''Also Sprach Zarathustra'' in the first episode.

* TheSmartGuy: Whenever he sides with the gang in the anime's ((FillerArc))s.

* SchoolUniformsAreTheNewBlack: Wore his school uniform during his first appearance, before it was replaced with his Kaiba Corporation white-collared outfit for the Death-Y arc. Averted in the present (unlike a certain rival of his),

-->"''Reluctantly, I cut short the episode with Priest Seto and Kisara [due to editorial deadlines], which is something I still regret, because, as all of you guessed, it is the defining episode for the relationship between present-day Kaiba and his Blue-Eyes White Dragon.''" [[note]]The rest of the liner notes are too long to post, but basically he describes how Kisara's death at the hands of Aknadin would have led to a subplot where Seto betrays the pharaoh and goes off on his own with the intent to avenge her demise. But apparently the series was starting to get less popular and the editors wanted Kazuki Takahashi to rush to finish the story, so his grand plans for the above were cut short.[[/note]]

** Heavily averted in Jonouchi/Joey's case, as he makes it clear how much he despises him for his actions during the arc. When Pegasus defeats Kaiba and traps his soul in a card, Joey personally voices his opinion that he got what he deserved.

** His infamous dragon obsession is also largely an anime thing. In the manga, the only dragons he really uses are Blue-Eyes and its fusions, and the majority of his other cards are Warriors, Fiends, and Beast-Warriors - Swordstalker, Judge Man, Battle Ox, Vorse Raider, Rude Kaiser, La Jinn, Ryu-Kishin, etc. His Deck was focused on brute force, rather than any given archetype. The filler arcs add a lot more Dragons to his Deck - Spirit Ryu, Different Dimension Dragon, Luster Dragon, Chaos Emperor Dragon, Spear Dragon, Clone Dragon, Paladin of White Dragon...

* CharacterExaggeration: The 4Kids dub of the anime takes Kaiba's rivalry with Yugi and contempt for Jounouchi and turns them UpToEleven. In the Japanese version, Kaiba makes it clear that he respects Yugi as a talented duelist and WorthyOpponent, while his dub counterpart is much more psychotically obsessed with defeating Yugi no matter the cost. Similarly his Japanese counterpart says it was a mistake to duel Joey to test his Duel Disk since it killed his motivation, while in the dub he calls him a worthless dog and spends the duel sneering at him. The dub also makes him a FlatEarthAtheist completely in denial of all the magical phenomena going on around him, no matter how obviously real it is. Japanese Kaiba doesn't deny the magic, he just doesn't care (in fact, in the manga, ''Dark Yugi's Shadow Games are what inspire him to create the Duel Boxes/Duel Disks'').

** JerkassHasAPoint: In her first duel with Joey, she points out that even if he and Yugi are friends, there can only ever be one champion, and they'd have to face each other in order to win. He also has to learn to step out from Yugi's shadow and duel on his own, and hopes that his defeat teaches that to him. And she's completely right except about the "defeat" part since he beats her.

** During the harbor deathmatch between Yugi and Jounouchi, he noted a disgust with the proceedings, claiming in the manga that "even at my worst, I would never have done this." This was because all the Death-T challenges, even the really lethal ones, were all possible to win without anyone dying (in fact, he bet that Yugi would make it through all of them), while there was no way to win the harbor deathmatch by its rules [[MortonsFork without someone dying]]. While he viewed Death-T as merely a high-stakes test, the harbor deathmatch was nothing more than a deathtrap.

** EmpoweredBadassNormal: He may not be an Item-wielder, but he does have some untapped mystical abilities, letting him wield Obelisk and Critias.

** BadassNormal: The most powerful Duelist in the series to lack a Millennium Item (the only other contender is Jounouchi, and that's only [[AdaptationalWimp in the manga]]). His only losses in the manga were both from wielders, and he's one of the few Duelists to beat an Item-wielder without being one himself.

** EmpoweredBadassNormal: He is one of Japan's top-level gamers who does not possess a Millennium Item or some other form of magical enhancement to his skills. In fact, all of his onscreen losses have come against Millennium Item-wielding opponents (most commonly Yugi, though not on account of said powers) and he evens owns one victory over the Millenium Item wielders (against Ishizu during the Battle City finals). That said, he also has a connection to the Millennium World background story/RPG via his ancestry. Then of course, there's also the fact that he owns the best and biggest collection of [[PowerEqualsRarity rare and powerful cards]].

* WorldsStrongestMan: Shortly before Death-T in the manga, Yugi and Jounouchi go to an arcade and check the high scores on a number of machines. Every single one has the top scorer's initials as "KAI." In fact, in the manga, it's a plot point that Kaiba's reputation as the world's best gamer was a big reason for how he held so much sway in his company.

** Last Turn was actually more about breaking through to Mokuba by showing him the Blue-Eyes. Had he used his Different Dimension Dragon instead, he would have tied with Noah in the anime adaptation (and had Noah not cheated earlier, Last Turn wouldn't have been neccessary.)

* ImprobableWeaponUser: Keeps the hammer from dropping on a gun with a Duel Monsters card in the manga, throws them at people to disable them in the anime.

** JerkassHasAPoint: In her first duel with Joey, she points out that even if he and Yugi are friends, there can only ever be one champion, and they'd have to face each other in order to win. He also has to learn to step out from Yugi's shadow and duel on his own, and hopes that his defeat teaches that to him. And she's completely right [[spoiler: except about the "defeat" part since he beats her.]]

* ActionGirl: In the anime, Manages to play the part by the end of her duel with Soichiro Ota.

* HeroicSacrifice: Played the special NPC Hasan during the Shadow RPG, and ended up shielding Atem and his priests from Zorc's Inferno.
