The god of sleep, also a close servant of Hades and the twin brother of Thanatos, who has fought against Athena's Saints since the ages of myth. Hypnos was more cautious than his brother and stayed out of the way from Athena's Bronze Saints. He did however act when the Saints gained a higher form of power as he thought them to be dangerous to the gods themselves, as he was witness of the power of the God Cloths in the ages of myth. In his effort to stop Pegasus Seiya he was however halted by the other Bronze Saints as they each successfully resurrected their God Cloths and severely wounded the god. Hypnos lived long enough to sense the moment when Hades true body was awakened, but succumbed to his injuries soon after.
