Kinnikuman

Kinnikuman wants to be treated as a great superhero, but his cowardice, clumsiness, and terrible reputation make that difficult. His life changes when the tiny Meat reveals that he is actually Suguru Kinniku, the missing prince of Planet Kinniku, and that he must prove himself worthy of his royal blood.

That path leads him into professional Choujin wrestling, where absurd comedy sits beside increasingly serious battles. Kinnikuman faces ruthless villains and powerful rivals in tournaments that test far more than strength, gradually earning allies among former enemies and learning what being a hero means when the people beside him are truly at risk.
