Centipede Soldier 2

Centipede Soldier 2 is one of the enhanced men the Centipede Project puts into the field. He came out of the United States Armed Forces before the project recruited him and fitted him with its hardware: a Centipede Device, a blood filter of Chitauri metal that feeds a mix of Extremis, gamma radiation, and elements of the Super Soldier Serum into him, and a backscatter x-ray implant in place of an eye that lets him see through a wall with his eyes shut. He can block a punch and crush the bones of the arm that threw it, he takes a beating without slowing down, and he heals fast. The serum does not hold, though. After a mission he is spent, and another injection is never far off.
