Here is what Ive always thought about a creatures true form:

God-Giant

Horsemen-Possible giants

Angels-Possible giants(remember Zach said he had five heads and one was a lion so that hints he isnt some person with wings and a halo)

Eve-Possible giant, we've seen her face, it would make sense for the mother of monsters to be as big as Godzilla, if not bigger)

Leviathans-Again since they are the truly first monsters, they are probably as big as Godzilla if not bigger, even if they were seen in the lake after they exploded from castiel)

Pagans-Some are possibly giants

Demons-Possibly giants

Some monsters-Some are possibly giants(like phoenix, it takes human form but probably a gigantic bird like creature)
