E-45 Sumo-Man

Eggman sends Sumo-man, an extremely strong, but unintlligent robot, to stop Sonic from winning a race with Sam Speed. Too big and slow to catch Sonic, Sumo-man takes it out on himself, hitting himself in the face. Underestimating his own strength, Sumo-man is sent flying and crashes into Eggman's base. Sumo-man was 12 meters (40 feet) tall and weighed 30 tons.
