User blog comment:ImperiexSeed/The oldest being, archangel or leviathan?/@comment-99.188.173.199-20130627004928

this is a silly question, if sam and dean can take out a laviathan (or temporaily disble them at anytime) an archangel would have not a shadow of a doubt in wining a fight with a leviathan. Even if the archangel didn't have the "weapon" needed to make the leviathan flounder he could easily decapitate it and cast the head off into oblivion.
