Hades

Hades (Saint Seiya) is the god and emperor of the Underworld. At first, Hades judged the souls of the dead fairly and justly, but he became more and more cruel as his discontent with humanity increased. It was then that he set his eyes on Earth, the domain of her niece Athena of hers, which would lead him to face off against it and hers knights in a succession of holy wars throughout history.
