cyborg

This guy looks just like any other high school graduate. Except he says he's got cybertronic legs and a robot brain. Also. He claims he was sent to earth by a "higher civilization" to save us from the Matrix.

This has to be the most terrifying soldier even put on the field. I'm not sure how other armies are going to survive or escape when this beast of a killing machine gets released onto the battlefield. It's lightning quick reflexes, it's deadly aggression, it's horrifying appearance...this is the stuff of nightmares!
