So that's how she's always been. yeah, i've thought about that part, and there are a lot of different theories (albeit there isn't really anything to go off of in canon when it comes to that) about why she would have prosthetics when gems can regenerate. some people think her gem could have maybe gotten damaged and she can't regenerate her limbs properly, as well as some other more complex theories.

idk, i find the possibilities of why she would have prosthetics very interesting, but i guess there's a pretty big chance we might never know for sure!
