S1LV3R or Silver is the Ultimate Cyborg. Even though he is just a cyborg, he actually is able to act very much like a human still. He was experimented a lot as a child as people tried to build the perfect being with all the knowledge in the world while still being human. He is able to speak and feel just as a normal human. As much as he doesn't want to though, he acknowledges himself as the cyborg he is, only wishing to be human again. His voice sounds like the average male. Dull, boring, and just normal.
