Hercules
One of the greatest heroes of classical mythology, he is supposed to have been the strongest man on earth. He was renowned for completing twelve seemingly impossible tasks—the Labors of Hercules. One of these labors was the cleaning of the Augean stables; another was the killing of the nine-headed Hydra. Hercules was a son of Zeus.
