“King Superman Versus Clark Kent, Metallo”

In "King Superman Versus Clark Kent, Metallo," a mysterious alien machine sets off a chain of strange events when it predicts that Supergirl’s powers will be influenced by the letter "LL." As she encounters words containing that sequence—some helpful, others oddly disruptive—her usual confidence is tested in ways she never expected. With dynamic art by Jim Mooney and a striking cover by Curt Swan and George Klein, this 1964 classic blends whimsy and suspense in a uniquely personal challenge for the Girl of Steel.
