Thanatos

Serving as a ruthless antagonist in the Saint Seiya universe, this personification of death acts as a powerful subordinate to Hades. As the twin brother of Hypnos, he possesses a volatile, hateful temperament and a deep disdain for humanity. After being imprisoned for centuries by Athena, he resurfaces to aid the resurrection of the Underworld's ruler. Distinguished by his silver hair and eyes, this merciless deity seeks to enforce mortality upon all living beings during the climactic battle for Earth.
