After years in a prison camp, scientist Karl Keller discovers a cache of dangerous Kryptonian chemicals—jettisoned into space long ago—and uses them to gain super-powers. Fueled by resentment, he heads to Metropolis to confront Superman, whom he blames for never rescuing him.
Meanwhile, during a battle gone wrong, Lex Luthor is accidentally killed by Supergirl. In a desperate bid to make things right, she journeys to Atlantis and then into space to bring him back to life. Upon his resurrection, Luthor is outraged—declaring he now hates Supergirl even more than Superman, furious that she made him a laughingstock by saving him.
Low to mid-grade estimate.
