Used in place of
Mr. Satan in the dragonball universe for censorship purposes. He became the world martial arts champion while the Z fighters were off doing other things. He is partially responsible for the defeat of Cell and Majin Buu, but instead of being modest he takes full credit for their defeat. He is the (overprotective) father of Videl.
Along with the Supreme Kai, Pan,
Fortuneteller Baba, and
Uub, Mr. Satan is one of the only characters out of the main cast who is never killed during the course of Dragon Ball Z and Dragon Ball GT.
Although weak compared to the majority of the cast, Mr. Satan is a skilled martial artist, and his strength exceeds that of most humans.
Akira Toriyama revealed in the Super Exciting Guide interview that Hercule first name is Mark (γγΌγ―, Maaku), a rough anagram of Akuma, which means "Devil" or "Demon" in Japanese, keeping in line with his family's naming scheme.
