Sumo the Samurai was a Japanese super-villain during World War II.
During the 1940s he fought against Wonder Woman and later her colleagues in the All-Star Squadron. He was the best pupil of a martial arts master named "The Enlighted One", and was selected to drink the "Potion of Power", vastly increasing his strength, speed, resistance and senses.
