Showcase Presents: World's Finest #3

In "Batman, Son of Krypton," a reimagined origin flips the script: Kal-El loses his powers to gold Kryptonite en route to Earth, while Lex Luthor uses a serum to become Superboy—and eventually Superman. Clark Kent, mourning the death of his foster father, takes up the mantle of Batman in a world where the roles of hero and villain are reversed. Written by Cary Bates and illustrated by Curt Swan with inks by George Klein, this alternate tale features a striking cover by Swan and Klein.
