User blog comment:ImperiexSeed/The oldest being, archangel or leviathan?/@comment-86.140.130.217-20120512145216

both death and frank have stated that leviathans are older than angels, humanity and souls so i don't think their can be any real doubt that leviathans are older than all angels, especially seeing as edgar says he personally new eve who is older than angels as well. it has been proved by edgar that leviathans are stronger than angels as he killed two of them with ease. also (like eve) they are immune to angelic powers probably because they know what makes angels tick. and it appears that their black goo is poisonous to angels. assuming that they are immune to the powers of an archangel ( which being older they probably are) it seems that high level leviathans would probably defeat the archangels.
