This character is a cyborg.
A cyborg is a being with both biological and artificial (e.g. electronic, mechanical or robotic) parts.
Fictional cyborgs are portrayed as a synthesis of organic and synthetic parts, and frequently pose the question of difference between human and machine as one concerned with morality, free will, and empathy.
Real cyborgs are more frequently people who use cybernetic technology to repair or overcome the physical and mental constraints of their bodies.
