Doom of the Star Diamond !

An alien named Carthan, exiled from his homeworld Dryanna and unable to speak clearly, arrives on Earth. He activates three powerful, dangerous machines across the globe and takes Green Arrow hostage — hoping the Justice League will locate and disable the devices, breaking his curse and setting him free. The team splits up: Flash & Aquaman head to Australia, Green Lantern confronts threats near Italy, while Superman & Batman find Carthan’s hidden ship and rescue their teammate. Together they shut down all machines, understand Carthan’s plight, and help him return to space. A classic Silver Age tale of teamwork, mystery, and cosmic adventure.

The Menace of the “Atom” Bomb !

A brilliant villain creates a weapon only the Atom can stop, testing the League’s smallest member.

Riddle of the Runaway Room !

A mysterious, moving chamber traps the heroes in a shifting, deadly puzzle.
