Hercule Satan is a human character in Dragon Ball Z, GT, and AF, and is a member of the Z-Fighters. Originally, Hercule was portrayed as a weakling, due to his complete ignorance of Ki, thus making him substantially weaker then Goku and the rest of the Z-Fighters. Because he so frequently was compared against the Z-Fighters and their adversaries, Hercule usually came off looking completely helpless. He is actually a genuinely skilled martial artist when compared to the average human; it is only against the Z-Fighters and those at that level that he found himself completely out of his league. However, this later changed after he trained with Gohan, and ultimately became one of the strongest non-Saiyan members of the Z-Fighters, able to go toe to toe with Goten in his base form.
