Mutations

I think Zodiarts have the human body is inside the Zodiarts in some sort of scifi cosmic energy way.
Basic Zodiarts don't need the human body at all at the end.
The Horoscopes Scorpion, Cancer, Leo, Aquarius, and especially Pisces have all changed there bodies in some way that I don't think there's a human body inside. And I'm willing to bet the other Horoscopes' change act in the same way
