Mutou, Sugoroku

武藤双六

Sugoroku Mutou is Yugi Mutou's grandfather. He gave Yugi his famous Millennium Puzzle as a gift, having recovered it from the tomb of the Pharaoh Atem in his youth. He owns the Kame Game shop, where Yugi and his friends obtain several of the games they play. He also taught Katsuya Jonouchi how to play the Duel Monsters card game. His fondness for games is evident in his name: "Sugoroku" is a Japanese game similar to Backgammon. Sugoroku is the reincarnation of Siamun Muran, an Ancient Egyptian vizier and right-hand man to the Pharaoh Atem.
In the original manga, Sugoroku’s ownership of the rare Blue Eyes White Dragon card led Seto Kaiba to target him. Kaiba stole the card from him and dueled Yugi with it. Yugi reclaimed the card, but Kaiba, seeking revenge, forced Sugoroku onto the dueling stage of his KaibaLand amusement park and defeated him, tearing up his precious Blue Eyes White Dragon card. While the Toei anime simply held the character hostage, the original manga depicted Kaiba taking his revenge further by subjecting Sugoroku to virtual reality torture. This was done to force Yugi to enter "Death-T," a series of games and amusement park rides intended to kill him, in exchange for Sugoroku's life. In the end, Yugi defeated Kaiba and Sugoroku was saved. The Duel Monsters anime reimagined and combined these two separate events into one. In this version, Kaiba did not steal the Blue Eyes White Dragon; instead, he kidnapped Sugoroku as his first move and defeated him in a duel, refraining from any further torture.
Things only got worse for Sugoroku when Maximillion Pegasus removed his soul from his body to force Yugi into competing in his tournament. In the original manga, Pegasus trapped Sugoroku’s soul in a video camera, while in the Duel Monsters anime, he imprisoned it within a Duel Monsters card. Sugoroku was freed when Yugi defeated Pegasus at the conclusion of the tournament. He continued to dispense support and advice for Yugi in his subsequent battles and duels.
The Duel Monsters anime gave Solomon Muto the chance to get back into the action during the KaibaCorp Grand Prix, which he participated in under an alias. In the Japanese version, he uses "Mask of Rock," while in the English dub of the series, he uses the alias "Apdnarg Otum," which is "Grandpa Muto" backwards. He duels Joey using an ancient-themed deck with a lot of rock monsters; Joey defeats him.
Sugoroku reappears in episode 75 of Yu-Gi-Oh! GX, where he is kidnapped by Thunder (Ikazuchimaru) and Frost (Kourimaru).
