Mr. Satan (also widely known as Hercule in Western localizations) is one of the most prominent comedic and surprisingly impactful supporting characters in the Dragon Ball Z franchise. While he is introduced as a flamboyant, arrogant showboat who fraudulently takes credit for the heroic deeds of Goku and the Z-Fighters, his genuine bravery, charisma, and compassion later morph him into a legitimate savior of Earth.
