Yu-Gi-Oh! Duel Monsters season 1

The first season of Yu-Gi-Oh! Duel Monsters, based on the manga by Kazuki Takahashi, premiered in Japan on April 18, 2000, and concluded on April 3, 2001, on TV Tokyo. The season was directed by Kunihisa Sugishima, and written by Junki Takegami, Masashi Sogo, and Shin Yoshida. The English version of this season premiered in the United States on September 29, 2001 on Kids' WB, and concluded on November 9, 2002.

The season follows Yugi Mutou and his friends - Katsuya Jonouchi, Hiroto Honda, and Anzu Mazaki (renamed to Joey Wheeler, Tristan Taylor and Téa Gardener in the English adaptation) - to Duelist Kingdom, a tournament on the island of the same name, to free the soul of his grandfather, Sugoroku (renamed Solomon Moto in the English adaptation) from imprisonment by Pegasus J. Crawford (renamed Maximillion Pegasus in the English adaptation). The last ten episodes deal with the aftermath of Yugi's duel with Pegasus, including several filler episodes featuring original storylines not seen in the manga.
