One of Yugi's classmates and closest friends. He has been with the main group throughout the series, although has only dueled once as himself. He was once briefly possessed by the Big Five to duel Yugi and Joey.
While duelling as himself he uses a mixed deck with monsters displaying weapons or military-themed designs. His ace monster is Super Roboyarou which really doesnt do much and lacks power. Although he does have Sengenjin, which is a much better monster.
