Eve couldn't be a Leviathan, for one think Leviathan can't cut off angels powers, there just immune to all but there physical ones, if you disagree, think this, Castiel still possed his superhuman strength and teleportaion when confronting the building, as well as Dick Roman, if the strongest Leviathan couldn't do it, then why could one that the others considered a mutt, do it?

Also Eve was weaker than Leviathans, and more varried in powers, Eve couldn't kill demons, if she could she wouldn't have needed to recruit Sam and Dean, which she tried to do, the Leviathans could wipe out the demon race in a heart beat, as said by Dick himself. Also Leviathans powers were all physicall, they couldn't do things like move a super speed, fly, read minds, turn others into monsters by a touch or those sort of thing, otherwise, they would have used them in several events.

In my opinion, if she was one, she was most likely a hybrid between a Leviathan and a very old pagan god, maybe these questions will be answered bfefore the seris ends in hopefully about three years.
