History
Over ten years ago, John Corben was in a terrible auto accident that nearly ended his life. Fortunately for him, he was discovered by scientist Emmett Vale who brought him back to his laboratory. Vale replaced all of Corben's skin, bone and internal organs with cybernetic components and covered the frame in a Plastex sheathe. He also replaced his heart with an artificial pump powered by Kryptonite. When Corben awoke on the operating table he was horrified.

He further told Corben that the Kryptonite within his chest cavity emitted waves of radiation that were deadly to members of Superman's alien race. read more
