(normal) Angels vs Leviathans, or at least high ranking ones.

Tendencies/powers of such classed based Leviathans:


 * Super strength, to which they can disembowel, rip apart of simply overpower humans, demons and apparently even angels.


 * Regeneration, and in spite of their immortality, the body they use can get injured, of which is responded by healing.


 * Basic true immortality, they can only be killed by Bone of a Righteous Mortal Washed in the Three Bloods of the Fallen.

Superhuman perception, more attentive than humans, and can tell if a human's possessed by an angel.

Now on to Angels, however as it will be too lengthy, I will not list their powers, if one doesn't know their powers set, look on their pg:

I still don't get how Edgar destroyed two angels. It just proves their poise, how threatening they really are. However, I'm sure an angel like Castiel could beat one, especially given his psychotic, delicate  state.
