Kinnikuman is about a young Choujin, by the name of, well, Kinnikuman. While most Choujin are well respected, Kinnikuman himself was not so fortunate, having to fight just to get even a shred of dignity for himself and his reputation. But despite that he never gave up, never stopped trying to prove himself, and trudged on. There are many different Choujin and monsters in the universe, some good, some bad, but one thing is guaranteed is that matches between choujin tend to be serious and quite devastating in nature. All competing for a great prize or to prove that they are the best.
Kinnikuman would eventually reach his highest goal, becoming the recognized King of Planet Kinniku, as well as de facto leader of the choujin world. However, the Evil Gods that attempted to thwart his ascent to the throne, in miserable defeat, were forced to find ways to persist after their avatars were defeated and/or killed. They, along with other threats in the Choujin world, would not make King Kinniku's reign a peaceful one if they had anything to do with it.
