In the Yu-Gi-Oh! manga In his introduction, Kaiba discovers that the grandfather of his classmate,
Yugi Mutou, owns the rare Blue-Eyes White Dragon card, and takes it from him. Dark Yugi emerges from within Yugi's Millennium Puzzle to challenge Kaiba to a Shadow Game to reclaim it. Kaiba is ultimately defeated, suffering Dark Yugi's Penalty Game: . Afterward, he plots to take revenge against Yugi and acquires the other three Blue-Eyes White Dragon cards through extortion and blackmail and builds "Death T," a "theme park" made up of deadly games designed to kill Yugi and his friends. He defeats Sugoroku and tears up his Blue-Eyes White Dragon; he also subjects him to an artificial Penalty Game, forcing Yugi to participate in Death-T or else he will kill him. Yugi once again defeats him and uses the power of his Millennium Puzzle to subject Kaiba to a Penalty Game, leaving him in a coma. Later on, Duel Monsters creator and Millennium Eye wielder
Maximillion Pegasus schemes to take control of from Seto by conspiring with its board of directors, the Big Five, and abducting his brother Mokuba. After Kaiba awakens from his coma, he learns of Pegasus' plans and his kidnapping of Mokuba and travels to Duelist Kingdom, where he regains his deck and briefly battles Katsuya Jonouchi (Joey Wheeler in English versions of the
Duel Monsters anime). Kaiba and Yugi later play the game atop the castle parapets, and Kaiba is nearly defeated until he endangers his life by balancing on the edge of the turret. Dark Yugi nearly kills Kaiba, but Yugi forces him to forfeit the game so Kaiba is not killed. Kaiba goes on to duel Pegasus, but is overcome by the power of his Millennium Eye and is defeated. Pegasus gives Kaiba the
Mind Card Penalty Game, sealing his soul into a card; when Dark Yugi defeats Pegasus in a Shadow Game during the final round of the tournament, both Kaiba and his brother are freed from their Penalty Games. In the Battle City arc, Kaiba is summoned to the Domino City museum by Egyptologist
Ishizu Ishtar, where he is shown an ancient stone tablet that depicts a battle between what appears to be his past self and the Pharaoh. He is interested in her tale of the God Cards – three powerful one-of-a-kind cards that Pegasus had entrusted to her. However, two of them were stolen by her brother
Marik and his Ghouls organization, and she gives the third –
God of Obelisk – to Kaiba, encouraging him to hold a tournament to lure in Marik and his organization. Seeking to obtain the remaining two God Cards for himself and eliminate Marik and his organization, Kaiba agrees and begins his "Battle City" competition. During the tournament, Kaiba teams up with Dark Yugi to rescue Mokuba and Yugi's friends from Marik's clutches. Afterward, Yugi, Kaiba and Jonouchi enter the finals, unaware that Marik has made a deal with
Dark Bakura, and he, along with Marik and Marik's stepbrother
Rishid, are registered as well. Kaiba trumps Ishizu's prophecy of defeat and claims victory. Kaiba faces Yugi in the semifinals, and the two unleash their God Cards against the other. Yugi manages to defeat Kaiba and go on to the final battle against Dark Marik. Kaiba gives Yugi the card
Fiend Sanctuary prior to the duel, and with it, Yugi is able to hold off the attacks of Dark Marik's
Sun Dragon Ra and defeat him in his Shadow Game.
In the Duel Monsters anime Shortly after his return from the Duelist Kingdom, the Big Five attempt to appease an outraged Kaiba by revealing they have finalized his virtual reality game software, and invite him to test it out for himself. However, this is actually an attempt to eliminate Kaiba, but Yugi and his friends manage to rescue him. The Big Five log into the virtual world in an attempt to stop them from escaping, but they are defeated in a duel and their minds become trapped in the virtual reality program. Some time later, in the midst of the Battle City tournament, the Big Five's digital consciousnesses are discovered stranded in cyberspace by a mysterious boy named
Noah, who recruits them for a revenge campaign against Kaiba. Noah admits to being Gozaburo Kaiba's biological son, and claims his mind exists as a computer program after he was fatally wounded as a child and later digitized. After Noah is defeated, Gozaburo reveals himself to be alive inside the Virtual World and sets a series of orbital missiles to launch and destroy the world. While Kaiba stops Gozaburo, a reformed Noah reprograms one of the satellites to attack the main computer database and helps Yugi and his friends escape. In Season 4 of the anime, Kaiba, along with Joey and Yugi, is one of three duelists chosen to fight the brainwashed
Atlantean King
Dartz. During the season, Kaiba meets
Alister, a man whose brother and parents were kidnapped by KaibaCorp-owned military forces under Gozaburo's command, though Gozaburo is actually Dartz in disguise. During the arc, Kaiba flips out upon learning Yugi lost to a duelist other than himself. Kaiba and Dark Yugi eventually duel Dartz, and although Kaiba loses, Dark Yugi defeats Dartz and Kaiba is restored, taking part in the battle against the Great Leviathan. In the first half of season 5, KaibaCorp's stock prices are at an all-time low as a result of a failed takeover by Dartz, and when Kaiba hosts a tournament to restore the company's reputation,
Zigfried von Schroeder (Kaiba's arch rival and enemy) infiltrates it and hacks Kaiba's computer systems. Upon catching Zigfried, Kaiba dispatches him in a duel. However, Zigfried has his brother
Leon duel Yugi in the finals. During the duel, Zigfried tricks Leon into activating
Golden Castle of Stromberg, releasing a computer virus into Kaiba's system and forcing Leon to attack, thus forcing his hand. However, Yugi prevails while Kaiba, who anticipated such a plan, had his computer systems backed up. Kaiba's only appearance in the original manga version of the Millennium World arc is in the last chapter. Although he does not take part in the Shadow RPG during the Millennium World arc of the manga, in the anime,
Yami Bakura gives him the Millennium Eye, which begins to show him visions and convinces him to fly to Egypt to determine if they are real or not. During the final battle, he is able to hold his ground against Zorc. In the original Japanese anime, Kaiba eventually acknowledges his past and the events that occurred within the Memory World Shadow RPG.
Yu-Gi-Oh! (1999 film) Kaiba is the main antagonist of the
Yu-Gi-Oh! movie, which was produced by
Toei Animation in 1999. In this film, he learns about
Shougo Aoyama's Red-Eyes Black Dragon and organizes a tournament where strong duelists are invited and attendance is mandatory. Shougo and Yugi are later pursued by Kaiba's henchmen from KaibaCorp, with Kaiba's henchmen overpowering them and stealing Yugi's Millennium Puzzle. Yugi enters Kaiba's tournament to show Shougo that one can have both the potential and the power to become a true Duelist. After the game, Kaiba tells Yugi that their battle is not over yet and informs him he is the only one in the world worth fighting as he leaves the arena.
Yu-Gi-Oh! The Movie: The Pyramid of Light Kaiba appears in
Yu-Gi-Oh! The Movie: The Pyramid of Light. In the wake of his defeat at the Battle City Tournament, he begins to suggest a means of defeating the three Egyptian God Cards that Yugi now holds to defeat him and reclaim his title as world champion. His quest leads him to Pegasus, as he theorized that he would not have created the Egyptian God Cards without creating a means of destroying them. After wagering his three Blue-Eyes White Dragons against the card that Pegasus promised him, Kaiba succeeds in winning their duel, only to find
two cards within Pegasus's deck that could accomplish what he sought. Kaiba challenges Yugi to yet another duel in his Duel Dome, and puts the first of the two cards into play – the enigmatic "Pyramid of Light," which prevents the Egyptian God Cards from participating in the battle. As the duel proceeds, however, it is revealed that Kaiba had been used as a puppet for the ancient Egyptian sorcerer, Anubis, who placed the Pyramid of Light card in Pegasus's deck. The Pyramid's powers drain the lifeforces of Yugi and Kaiba as the duel progresses, eventually resurrecting Anubis, who dispatches Kaiba and takes his place in the duel. With Kaiba's aid, however, Yugi puts the second mighty card into play – the "Blue-Eyes Shining Dragon", which is able to destroy any card in play. The Shining Dragon destroys the Pyramid of Light and later wipes out Anubis.
Yu-Gi-Oh! The Dark Side of Dimensions Kaiba appears in
Yu-Gi-Oh! The Dark Side of Dimensions, in which he commissions an excavation to retrieve the disassembled Millennium Puzzle from the ruins of the Millennium chamber. The item had previously housed the spirit of his longtime rival, Pharaoh Atem, whom he hopes to "return to life" in order to settle their ancient score. The excavation is interrupted by Diva, who faces Kaiba in a game of Duel Monsters and steals two pieces of the recovered Puzzle. He keeps one fragment and gives the other to his younger sister Sera, who passes it on to Yugi, as he is the only one who can reassemble the Puzzle, having been the host of Atem. Kaiba has a computer that rebuilds the Millennium Puzzle and discovers the last two pieces are missing. He abducts Diva and approaches Yugi so he can have the two partake in the showcasing of his updated Duel Disk virtual reality technology. He intends to duel both Diva and Yugi, while gambling their pieces of the puzzle. However, Yugi is furious with Diva over what he did to Bakura and insists he duel him instead, which Kaiba agrees to. Yugi defeats Diva, resulting in Bakura's return to reality, and while dueling Kaiba, he re-completes the Millennium Puzzle, revealing that the spirit of Atem is no longer inside it. Diva becomes corrupted by the evil powers of the Millennium Ring, and duels both Yugi and Kaiba. Kaiba sacrifices himself during the Duel and makes a final plea for Yugi to call forth Atem. Yugi succeeds in doing so, and he and Atem defeat Diva. Atem and the Millennium Puzzle then fade away, and Kaiba and everyone else return to reality. The film concludes with Kaiba using his technology in conjunction with the Quantum Cube to transport his own consciousness to the afterlife and face Atem.
