- Nicknamed as Bandit Steve Keith, is an American Duel Monsters champion and a "Card Professor", hunting big prizes at tournaments.[1] Keith first appears as one of many entries in the Duelist Kingdom arc of the anime/manga. In flashbacks, it is revealed that he was once the champion of Duel Monsters in America, until he dueled Pegasus at the American Championship tournament (taking place some time before the Death-T arc of the manga). Keith, shocked and humiliated at being defeated, became depressed over the defeat and seeks to defeat Pegasus and reclaim his lost glory. It's through Pegasus' match with Keith that Kaiba found out about Pegasus' ability to read minds. After he cheats in his duel against Joey in the Duelist Kingdom semi-finals, Pegasus inflicts the "Hand and Gun" Penalty Game on him, turning his hand into a gun and forcing him to play Russian Roulette, effectively killing Keith. In the anime, Pegasus instead sends him through a trap door into the ocean. He survives when he is picked up by Marik Ishtar's ship, with Marik then controlling his mind and using him in his first attempt to defeat Yugi and take the Millennium Puzzle.
