User blog comment:ImperiexSeed/The oldest being, archangel or leviathan?/@comment-5110811-20150606210717/@comment-5110811-20150610235307

I find it hard to believe that a leviathan, even the top ones like Dick and Edgar, can negate an Archangel's power. Knowing that the Archangels were made to help God win the war against the Darkness. They should have a far greater resistant to the leviathan's negation ability. If not near-immunity.

Take a look at Cain, for example. He is the demon equivalent of archangels. He's by every definition an archdemon. Cain is virtually immune to all demon weaknesses. Not even a Devil's trap can hold him for long. He's even capable of using his full super-strength and telekinesis while in it. The demon-killing knife doesn't even make him flinch or wince in pain. It has zero effect.

When you take away the one power the levaithans possess which is power negation, they've got nothing going for them, just by judging their feats on the show.
