Small-time conman John Corben was nearly crushed in a car accident, but robotic specialist Emmett Vale rescued Corben, transplanting his still-functioning brain into a robotic body powered by kryptonite. After Corben's operation, Vale told Corben he had to destroy Superman; fearing an invasion from Krypton. Corben instead snapped Vale's neck and embarked on a career as a rampaging, homicidal nightmare who desired nothing less than the death of Superman.
