Character Profile: Hercule

Mr. Satan is a physically strong human who is famous among the Earth beings for being "the strongest fighter in the world" and a hero, but he is really nothing but a coward. He even paid Krillin's wife, Android 18, for beating up people for him. He's mostly just kind of there through most of the shows.

Hercule's status is world martial arts champion. He brags about it constantly after the Cell Games.

He did help save the universe, though. When Goku was charging up the spirit bomb, the people of Earth wouldn't have given there energy if Hercule haldn't talked them into it. And, because he said it, they thought he destroyed Kid Buu.

When Goku needed Energy for the Spirit Bomb, it was Mr. Satan that got the inhabitants of Earth to give up their energy. But that is not why Goku says that Mr. Satan helped, it was because when Goku needed to throw the Spirit Bomb at Kid Buu, Vegeta was still in the way and Goku refused to kill Vegeta, so Mr. Satan ran out and pulled Vegeta away so Goku could throw the Spirit Bomb at Kid Buu in good conscience.
