(Okay, big backstory for Katrina i just thought up. Her parents had been the rulers of the humans before the robots killed them. She was just a baby when it happened,and her arm was injured. The robots found her, switched her arm with a robot one, and gauged out her eye, replacing it with a robot one. She never forgot her parents, because the robots kept showing her clip after clip of them dying. They had erased all info on her, and she escaped them. Now she lives in. World where no one knows her.)
