Mister Satan

His name in the original Japanese version media is Mister Satan. It was changed to Hercule in FUNimation's English dub and Viz Media English version of the manga. In the U.S. edition of Shonen Jump it is explained that Hercule is the real name of the character while Mr. Satan was his stage name though no such explanation was present in the original. He is voiced by Daisuke Gouri in the original Japanese version, Chris Rager in the FUNimation version and by Don Brown in the English version from the UK and Canada. ~!Even though he has never directly saved the world he is highly responsible for defeating Kid Buu as he convinced everyone on earth to give power to Goku's Genki Dama, along with his direct role in defeating Majin Buu. A common point of humor after his first appearance in the Cell Saga is his extremely inflated ego, arrogance and craving for the spotlight which the Z Fighters find annoying at best. Interestingly enough, he never lost any World Tournament that he attended in the series, nor has he died, making him one of the few characters not to have done so along with Pan, his granddaughter. He has a daughter named Videl who dates/marries Son Gohan. A reference to this is made in the video games Dragon Ball Z: Budokai Tenkaichi 2 and Budokai Tenkaichi 3. If the player matches Adult Son Gohan and Mr. Satan the opening dialogue starts with Mr. Satan saying "If you want to go out with my daughter, you'll have to go through me!" Gohan replies, "Wait, it's not like that!" The fight then begins.!~ Source: Wikipedia
