- A minion of Amiba's who was given the strength of the bull. He goes around challenging men to arm-wrestling promising them a month's worth of food if they win. Gyūki arm-wrestles a man on a table saw and sliced the man's arm off. Kenshiro then takes Gyūki's challenge and stunned everyone present by beating Gyūki and cutting his arm in the process.
