I don't think Curie would go out of her way to raise the level of a Metang to evolve into a Metagross. It also defeats the visual purpose of it already somewhat resembling a Mr. Handy by being a floating metal body with arms.
Chimeco is a floating white ball that is kind in nature and harmless. Like Curie.
Feraligator is similar to death claws in visual design, I felt like Curie would have no problem befriending vicious wildlife.
Very correct about Ratata c: Especially because of the vault you find her in.
As in, finding the original? lol. It's so old!! I'm seeing it get looked at a lot more recently tho!
