Solomon Muto AKA Sugoroku Mutou in the original Japanese anime and manga, is the grandfather of Yugi Muto. It was Solomon who gave his grandson the Millennium Puzzle; since he discovered it on an expedition in the Valley of the Kings in Egypt when he was a young man. Solomon currently owns a game shop and is the only person in the world to own a Blue-Eyes White Dragon card besides Seto Kaiba.
In the English dub version of the anime by 4Kids Entertainment, Solomon was voiced by Maddie Blaustein. In episode 199 in a flashback a younger Solomon Muto was voiced by Marc Diraison.
In a lesser known English dub by Odex Ltd Solomon was voiced by Chuck Powers.
For the English dub of Yu-Gi-Oh! 3D: Beyonds Beyond Time, the character is voiced-matched by Wayne Grayson to the late Maddie Blaustien.
