Thanatos Sightings

The Iliad by Homer 800BC - 600BC
Thanatos and his brother Hypnos were big-time heroes when they took the body of Sarpedon peacefully away from the battlefield in Homer's epic poem about the Trojan War.
Alcestis by Euripides 438BC
In this play, Thanatos is totally humiliated when Heracles beats him in wrestling, allowing Alcestis to avoid death. (Yeah, this is definitely not Thanatos's favorite play.)
God of War Series 2005
In this gory video game, Thanatos is eventually slain by the mighty Kratos. Ouch.
The Incredible Hercules 2010
Thanatos shows up to do some major psychopomping in this Marvel comic book.
The Son of Neptune by Rick Riordan 2011
In this installation of the Heroes of Olympus series, Thanatos ends up chained to a glacier, which causes all kinds of problems. (You'd think Thanatos wouldn't let himself get chained again after that embarrassing Sisyphus incident…)
