Kinnikuman

Kinnikuman is a superhero...a bad one. The one day a person named Meat tells Kinnikuman that he is the prince of an alien planet. Kinnikuman must save the day numerous times fighting evil chōjin and competing in tournaments to prove himself to his family and to gain respect and money.

Kinnikuman has proven himself worthy to be crowned the next king of Planet Kinniku. But at the ceremony, five other Kinnikuman's arrive, all claiming to be the true prince of Planet Kinniku. Now, a Royal Survivor Tournament is being held to decide the true successor to the throne, and with the help and support of his friends and with his recently acquired knowledge of the Ultimate Technique (The Muscle Spark), Kinnikuman fights for what is rightfully his.
