Super Duper Sumos (Korean: 으랏차차 삼총사) is an animated series co-produced by DIC Entertainment, L.P. and Ameko Entertainment. It was created by Kevin O'Donnell and Vincent Nguyen.

Three crimefighting sumo wrestlers — the brothers Booma, Kimo, and Mamoo — go on adventures and fight using their enormous size and gigantic hindquarters.

A typical episode consisted of "Bad Inc" trying to destroy Generic City in numerously themed ways, although almost all of their plans involved giant monsters. The head of Bad Inc, Ms. Mister, usually assigned the in-house mad scientist Stinger to create these evil monsters. At the end of each episode, Ms. Mister fires Stinger for failing to create an unstoppable monster (although he always appears employed in the next episode and is never actually fired). Every episode contained gratuitous use of the word "butt".

In every episode, the three wrestlers use "Sumo Size". This makes them stronger, more muscular, and considerably larger. Each sumo has a characteristic move they use when "Sumo Sized", usually the three sumos initiate their attack one after another in the same order. Often in times of trouble, the sumos undertake a flashback remembering something Wisdom San (their teacher) taught them. They also may get advice from Prima, who is the sumos' friend and encouraging sidekick who often follows them and acts the most sensibly. Throughout the whole series, each sumo fights for their own cause (they draw their abilities from a force known as 'P.H.A.T.', standing for Peace, Honor And Truth).
