AKA: Maximillion Pegasus (English dub)
Chairman of Industrial Illusions and creator of the card game Duel Monsters in Yu-Gi-Oh! Duel Monsters. The core antagonist of the Duelist Kingdom arc, but was not a villain afterwards.
As the creator of the card game Duel Monsters and also the discoverer of their ancient Egyptian roots, Pegasus often plays a key role throughout the anime due to his extensive knowledge of the game and its mysterious origins. He has a habit of calling Mutou Yuugi "Yugi-boy" and Kaiba Seto "Kaiba-boy" in the Japanese and edited English versions of the anime and manga. Despite his age, he has an obsession over cartoons, which inspired him to create his iconic Toon World cards.
