Thanatos

Thanatos was the Greek god of death. Thanatos was the son of Nyx (Night) and brother of Hypnos (Sleep), as well of Moros (Doom), Nemesis and Fates.

At Troy, Thanatos and Hypnos carried the body of Sarpedon home in Lycia, when Patroclus killed Sarpedon.

When Alcestis was fated to die in her husband's place, Heracles restored her to Admetus by wrestling with Thanatos.

Heracles probably wrestled with Thanatos again in the Underworld during Heracles' twelfth labour. Heracles only spared Thanatos at Persephone's request.
