Sumi was an enormous man of thick build, his head shaved apart from a topknot. He wore an eyepatch over his left eye and a green loincloth.
"Dragons of Ashida"Edit
The hulking servant of Dr. Ashida, Sumi is the one who trained Ashida in the art of Judo and Karate, a wrestling champion who retired without ever losing a match. Sumi looked after Ashida's dragons, and was the only human that the giant lizards feared. Despite his indispensibility, the cruel Ashida treated Sumi harshly, subjecting him to multiple beatings whenever he displeased him and constantly threatening to feed him to the dragons. Eventually, Sumi grew tired of Ashida's brutal treatment of him. He threw Ashida into the pit with the dragons, where the reptiles devoured the evil scientist.
Afterwards, it is assumed that Sumi remained living on Ashida's island.
