E-45 Sumo-man is an extremely strong but unintelligent E-Series robot.
Doctor Eggman sent Sumo-man to interrupt the race between Sonic the Hedgehog and Sam Speed in episode 21 of Sonic X. Despite of his seemingly immense strength he is too slow to hit either of them. Feeling guilty of failure, 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 Egg Fort II. Sumo-Man stands at 12 meters (40 feet) tall and weighed 30 tons.
