Justice League of America #191

In "The Key Crisis of the One-Man Justice League!", the mysterious Key intercepts Amazo adrift in space and uses his unique power-siphoning abilities to strip the Justice League of their superhuman abilities, leaving them vulnerable. With the team weakened and the villains on the rise, even Zatanna notices an unexplained loss of her own magic—though she’s unsure if it’s tied to the crisis. Written by Gerry Conway and illustrated by Rich Buckler, with inks by Pablo Marcos, colors by Carl Gafford, and lettering by Gaspar Saladino, the issue features a cover by Rich Buckler and Dick Giordano.
