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, Honour And Truth).
