The Mystery Duelist, Part 1, known as Challenge from the Past - The Terrifying Zera in the Japanese version, is the fifty episode of the Yu-Gi-Oh! anime. It first aired in Japan on April 10, 2001, and in the United States on November 16, 2002.
Yugi Muto now has changed his Millennium Puzzle brown rope to a chain to keep his Millennium Puzzle safe. Yami explains that this change is vital since the Millennium Puzzle connects the two and that faith has more in store. Then Yugi Muto and Téa Gardner are rushing to the soccer game when they come across a fortune teller who Yugi beileves can help him see what is in the future for him. The fortune teller asks for a personal item and suggest the Millennium Puzzle which, once in hand, he steals it. Téa runs into Yami Bakura who wants the Millennium Puzzle and uses his Millennium Ring to find the Millennium Puzzle. The fortune teller then alarms Yugi the only way to get the puzzle is to win it in a Duel. But the catch is since the Millennium Puzzle isn't close or on Yugi then he would have to do this Duel without Yami Yugi's help. During the Duel Yugi realizes that only one person has a lot of machine cards and that is Bandit Keith. His guess is right but it is not truly Keith since he is now the host of someone else, Marik Ishtar.
- Keith is under the control of Marik Ishtar, who cheats during this Duel.
- Whoever wins this Duel gets to keep the Millennium Puzzle, which Keith stole earlier disguised as a fortune teller.
- Yugi is forced to Duel without Yami. In the English version, this is because the Puzzle is not within Yugi's reach, weakening his bond with Yami. In the Japanese version, Marik staged the Duel so Yami would take over to protect Yugi, giving Marik a victory over the pharaoh as well as possession of the Puzzle. However, Yami senses the trap and holds back.
