Kinnikuman: New York Kiki Ippatsu!

A major Justice Choujin tournament brings fighters such as Terryman and Robin Mask to New York, only for a new enemy calling himself Akuma Shogun to crash the event. He defeats the fighters one after another and absorbs their powers, building their combined strength into his own body.

Kinnikuman escapes the initial attack for the most ordinary of reasons: he arrives late after stopping for gyuudon. With every other Justice Choujin already beaten, the responsibility falls entirely on him. To save his friends, Kinnikuman must face an opponent armed with the very abilities that once made each of them formidable.
