Yeah, Galatea herself fits the myth background perfectly. I don't consider them "the obligatory sexy [category]", because every Promethean is tragic in different ways. The Galateids were still created and abandoned, still hated by humanity, still cold stone animated by blood and Pyros.

I'm not a huge fan of how their Disquiet generally takes a sexual tint, but it's somewhat fitting, since they partially express the theme of people created specifically to act as lovers or sex objects. No matter what they try to do, they can't get away from the fact that this is what they're for, this is how everyone sees them. Rather maddening.
