This is the first generation Kinnikuman BEFORE the one that came to America and a lot better. It stars King Kinnikuman in his struggle for humanity. That's right. This is the show where we see Mantaro's father before Mantaro was even born. If you still don't know what show I'm talking about, I'll quote one of the most famous songs from the show:
    "Gyuudon only 300 yen per bowl; it tastes very good; it's fast and cheap"
    Anyway, this is one of the greatest shows from Japan and can sadly only be viewed if imported. It was also a bigger success here, which is odd because America never got this dubbed. Unlike the slightly less popular Nisei, every character has his own theme song. That has to account for something. Anyway, here's a more accurate summary if you want it:
    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.
    I hope that this is very informative.
