Maximillion Pegasus, the super-rich American who designed the Duel Monsters game, forces Yugi to compete in a tournament on Duelist Kingdom; however, Yugi's grandfather's fate is at stake and Yugi hopes to win against the power of the Millenium Eye.
Yugi battles Bakura in the pharaoh's empty tomb for Yu-Gi-Oh's forgotten Egyptian name, while massive earthquakes threaten the World of Memories and unleash the undead armies of Zorc Necrophades.
Yugi faces stronger opponents in even stranger games. Monster Fight takes on a whole new meaning when Yugi put his soul in the figure. Then, a classmate challenges him to Dragon Cards, a magical card game.
Yu-Gi-Oh fights the original Dark Magician, Mahado, in a three-thousand-year-old battle, unaware if changing the past will change the present; meanwhile, Yugi, Anzu, Jonouchi, and Honda battle an enemy who has been with them all along.
When the third and most powerful of the Egyptian God Cards is released, Jonouchi must battle the terrifying Sun Dragon Ra, while Marik faces off with Mai Kujaku.
As the game's greatest duelists gather for the Battle City tournament, the Rare Hunters, pawns of the mysterious Marik, stalk the tournament, stealing valuable cards and forcing Yugi to find a way to beat an unbeatable combo in order to win.
As the Battle City tournament draws to a close, Yugi must use all his skills and weapons to ensure his victory, even if it means destroying the tiny island and all it holds.
