“The Mighty Annihilator!”

In "The Mighty Annihilator!", scientist Karl Keller, long imprisoned in a remote Iron Curtain-like regime, stumbles upon a hidden cache of dangerous Kryptonian chemicals. With their power, he gains incredible abilities and sets his sights on Metropolis, determined to confront Superman for failing to save him—turning the hero’s greatest adversary into a man who might just be beyond even Superman’s reach. Written by Leo Dorfman and illustrated by Wayne Boring, with a striking cover by Curt Swan and George Klein, this 1967 classic delivers a chilling twist on the classic hero-villain dynamic.

Karl Keller, a scientist in an Iron Curtaun country, has been held in a prison camp for years when he discovers a cache of Kryptonian chemicals that were shot into space because they were too dangerous. He experiments with them and then uses them to gain super-powers, traveling to Metropolis to challenge Superman, whom he blames for never rescuing him from captivity.
