Justice League of America, Vol. 1 #136 (1976)

Crisis on Earth-S
With the powers of the gods inactivated, Shazam's magic lightning no longer transforms Billy Batson, Mary Batson, or Freddy Freeman into the Marvel Family, so the newly recruited heroes of the JLA, JSA. and Squadron of Justice must act in their stead to save Earth-S. Batman and Robin of Earth-Two and Mr. Scarlet and Pinky overcome the Earth-Two Joker and the Weeper, while Hawkman and Hawkgirl team with Bulletman and Bulletgirl to defeat Dr. Light and the Shade.
