Story featuring Superman,
Story featuring Challengers of the Unknown
Storyline: At the Daily Planet, the Challengers of the Unknown seek help to contact Superman to help them solve the mystery of a card with a Kryptonian letter. Superman uses his mind-prober ray to recall Zo-Mar, a Kryptonian criminal shot into space before the discovery of the Phantom Zone, and his mind-slaving card. Superman and the Challs find Zo-Mar, but he enslaves them all with his card. The card, however, inhibits Kryptonian super-powers, and when Superman and the Challs trick Zo-Mar into grabbing the card, they make him weak enough that Superman can knock him out and send him to the Phantom Zone.
