Archangels would anahalated them easily, they are the most powerful force in the universe(aafter god and death ofcourse). Michael is strongest in term of natural power and lucifer is sightly behind him. as we all saw it ALL Levathians could only slowly overtake Castiel who was pumped with all them souls but if it was one, it couldn't do anything. I always believe archangel could defeat Eve and other beings as archangels can only be killed by their sword, another archangel or angelic sibling pumped with vast amount of souls, nothing else outside that can harm them.
