Sumo-Man stands at 12 meters (40 feet) tall and weighed 30 tons.
Dr. Eggman sent Sumo-man to interrupt the race between Sonic the Hedgehog and Sam Speed. Despite of his seemingly immense strength he was too slow to hit either of them. Feeling guilty of his failure, Sumo-Man took it out on himself, hitting himself in the face. Underestimating his own strength, Sumo-man was sent flying and crashed into Eggman's Egg Fort II.
