If I apped Rin, would she get to keep her robot body? This would not give her any significant advantages in killing, but it would give her advantages in not being killed - basically it would narrow down the ways you can kill her. Drugs and poison wouldn't work at all, stabs would not cause her to die from bleeding so they'd only be effective if they pierced something important (like a motherboard, or if they cut a fuel tube or whatever BS we wanna make up.) Bullets and fire would be super effective. I'm imagining her to be about as durable as a car.
