Terror Inc. (Marvel) showing several "acquired" limbs
Attach the body parts of others in place of your own
The power to replace one’s missing appendages with those of another.
The user can replace parts of their body with same organs from outside sources, gaining the powers they'd had before the connecting, such as an eye with night vision would give the ability to see in the dark, a hand taken from a plasma blaster could allow them to fire plasma blasts from that hand.
Users may have a place to keep multiple organs and limbs, this way they can remove what they have and replace it with something they need, or to replace a lost limb and couldn't replace it in case they couldn't find one.
