Part man, part machine. Nathan is a violent fusion of a experimental robot structure and a skinny scientist. His body is littered with metal, wiring and other parts. His bodily hair burned in the accident that created him, and it never grows back. Nathan is not completely covered in metal. His torso, neck and parts of his head and face took the most of the blast from the accident, causing these areas to be covered in metal, while his arms and legs are mostly unaffected. His blue eyes have two pupils, almost merged together.
