Thanos

Thanos originated as a short form of Athanasios, a Greek name meaning "immortal." It is composed of the elements a, a negative Greek prefix, and thanatos, meaning "death." St. Athanasius, who used the Latin spelling of the name, was a bishop of Alexandria and known for his opposition to Arianism.

Though this is a perfectly respectable Greek choice, be aware that Thanos the Mad Titan is a sinister Marvel Comics villain.

Pronounced THAN-os.

As of October 2026, Thanos ranked #13966 in US births in 2023 SSA, peaked at #5318 in 2019.
