The Duel between Yami Yugi and Yami Bakura took place during Battle City. It was determined by an Ultimate Bingo Machine developed by KaibaCorp. It was the first duel that happened in the semi-finals. Before the duel took place, Yami Yugi noticed Bakura's expression was vicious, and realized the evil Bakura (Yami Bakura) had taken over. When they got to the top of the blimp, Marik Ishtar, pretending to be an innocent duelist named Namu, asked Joey (Jonouchi) about the Millennium Ring and Bakura's possession. Then, the duel started.
