Kinnikuman: New York Kikiippatsu!

Meat has been kidnapped by Iron Mask. In order to save Meat, the treasure of Inmora Island is needed. Furthermore, the treasure is hidden in the Seven Story Tower, which is guarded by the brutal Warrior Choujins. When Kinnikuman asks Terryman and the Justice Choujin to help him, for some reason they all refuse. Alone, Kinnikuman heads to Inmora Island to fight the Warrior Chōjin and is overwhelmed by their great numbers.

Mari and Kinnikuman's Championship Belt are stolen by the Octopus Dragon and his minions. Now Kinnikuman and the other Justice Choujins must travel to Planet Metro and compete in a tournament in order to win them back.

As the whole world watches the Choujin Rugby game on TV, the "Underground Space Emperor" Hydra King has his Underground Space Supermen kidnap Robin Mask. Their aim is to lure out the Justice Choujins and then attack them using the Robin Memo, which contains info on all of the Justice Choujin's weaknesses. Watching on TV all over the world, Kinnikuman and the Justice Choujins get together and head for Planet Hydra.

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 chiyojins and competing in tournaments to prove himself to his family and to gain respect and money.
