Seto Kaiba (Japanese: 海馬 瀬人, Hepburn: Kaiba Seto) is a fictional character in the manga Yu-Gi-Oh! by Kazuki Takahashi. As the majority shareholder and CEO of his own multi-national gaming company, Kaiba Corporation, Kaiba is reputed to be Japan's greatest gamer and aims to become the world's greatest player of the American card game, Duel Monsters (Magic & Wizards in the Japanese manga). In all mediums, his arch-rival is the protagonist of the series, Yugi Mutou, who is also a game player while Zigfried Von Schroeder is also his arch-rival. He is the modern day counterpart of Atem's cousin son of Aknadin nephew of Aknamkanon and one of the Pharaoh Atem's Six High Priests, "Priest Seto", who appears in the manga's final arc. Kaiba has also appeared in related anime and feature films. His signature monster is the Blue-Eyes White Dragon.
Seto Kaiba originates from one of the stories Takahashi heard from a friend involving a selfish card collector. Like the card collector, Kaiba is obsessed with gaming, but Takahashi also gave Kaiba a calmer demeanor when developing his relationship with his rival. He was first voiced by Hikaru Midorikawa in Japanese, with Kenjirō Tsuda replacing him in the sequel Duel Monsters. Eric Stuart voiced him in all of his English appearances.
Critical reception to Kaiba has been mixed; he has been compared to simplistic anime rivals based on his multiple attempts to defeat Yugi and become the superior Duel Monsters player. While his development in the film Dark Side of Dimensions was praised for being a major focus in the narrative, critics still felt Kaiba's obsession with Duel Monsters and focus on his original goal made him come across as a one-dimensional character. Nevertheless, the character has become popular amongst fans of the series, who felt that his motives made him more enjoyable despite lacking substance.
