Robot Arms

If I ever lose my hands or my whole arms, I want to get robot arms (or hands) similar to Jax's from Mortal Kombat. Ideally, I would also be able to launch my fists or fingers as projectiles and remote control them, then reattach them. I think it would be cool to get some palm mounted repulsor rays and some kind of grappling cable launcher similar to the batclaw too. Or a different idea is to have magno locks like War Machine had when he lost his arms and legs and half of his face looked like a Terminator.
