Minor Greek god of death, known as the Reaper of Souls because of his job of collecting the spirits of the dead and taking them to the Underworld. He's Hades must trusted servant and one that never fails his missions [until he encounters Vergil that is 😅]. Thanatos is sent-- along with Alecto and Cerberus-- to kill the Chosen One before she gains more power.
