Abaddon

An uncommon biblical name, Abaddon is the name of an angel of abyss in the New Testament. A totally cool name for a fictional character perhaps, though on a child it might be too reminiscent of the phrase "a bad 'un" or the word "abandon".

Pronounced uh-BAD-uhn.

As of October 2026, Abaddon ranked #10817 in US births in 2023 SSA, peaked at #8736 in 2020.
