User blog comment:ImperiexSeed/The oldest being, archangel or leviathan?/@comment-4011543-20111222122718

Well, Lucifer had no trouble killing the gods, but only because the gods were created by Eve and not by his Father. I personally think an Archangel would lose to a Leviathan because the Leviathans were created by the Lord Himself.

Anyhow, in terms of demon hierarchy, this is how I see it: Lilith (the White-Eyed Demon) > Azazel (the Yellow-Eyed Demon > Archeri > Raksasha > Red-Eyed (Crossroads) Demons > Black-Eyed Demons (Ruby, Meg and Tom)
