Amy got a shattered variation which is where she is missing a piece of her gem which injures her and how did that happen is when she refused to follow Alex's orders so he had to shatter a piece of her to make a prototype and then dispose of her(as in just throwing her away and does not kill her) since she's no use to him since she rebels against villainy and she's only useful for the dark amethyst powers... but since she won't use her powers for evil, he had to take a piece of her and created Project Abyss and make him completely stronger than her... though she still got her powers but she got hurt and weaker... meanwhile Abyss is a prototype dark amethyst combined with the Shadow Obsidian fragments Alex found which is Shadorix's Fury and he's filled with pure malice
basically shattered is her injured form
