Origin: Greek

Meaning: Immortal

Thanos is a boy’s name of Greek origin and flows from the name Athanasios, meaning “immortal.” Thanos is known in Greek mythology as a shortened name for the Greek god Thanatos. But if you’re into Marvel movies and comics, there’s so much more to Thanos than the part he plays on Mount Olympus. Avengers: Endgame might tell you that The Mad Titan and his glory were short-lived, but the legacy of your little one will live on and on!
