Sumo is one of the three main characters in Clarence. He is one of Clarence's friends. He loves to do all sorts of crazy things so that he can enjoy having fun with Clarence and Jeff and the other kids. He is voiced by Tom Kenny.


Sumo is a scrappy, streetwise kid who grew up on the right side of the wrong side of the tracks. When problems arise, Sumo's solutions are unorthodox and often messy. A wild card and fearless to a fault, Sumo is unpredictable, independent and often acts without thinking things all the way through. Sumo is fiercely loyal to his friends and always available. Jeff and Sumo are polar opposites, but Clarence bridges the gap between them. Sumo is the instinctual third of this trio.


Sumo used to have long golden hair but asked Clarence to cut it, as shown in the Pilot. He currently has no hair at all, except for several strands. He has a big forehead, small and somewhat crooked teeth, with spaces inbetween some, and has big eyes and big pupils aswell. Sumo wears a black t-shirt, blue jeans, and dark red shoes.
