Synopsis:
Although the Atom is elected as the Justice League’s newest member, no one can remember exactly who he is, or why votes were cast for him. After Green Lantern consults his power ring for the information, J’onn J’onzz is sent to inform the Atom of this strange circumstance, and the meeting adjourns. Meanwhile, in Ivy Town, the entire citizenry, including the Atom himself, forgets about him, and the Tiny Titan is trapped, a victim of amnesia in a world of giants.

The power behind these happenings is a mystery mastermind calling himself Mister Memory, who has invented a De-Memorizer weapon. He recruits Hector Hammond (who uses his evolution-meteor to transform himself into a man of the future), the Pied Piper, the Sea-Thief, the Angle-Man, and Dr. Davis to help him capture Green Lantern, Flash, Aquaman, Wonder Woman, and Green Arrow. Mr. Memory captures the Martian Manhunter, just as the hero is about to confront the Atom. Stunned by the appearance of J’onn J’onzz, Atom accidentally shrinks into a sub-atomic world, and the shock restores his memory.

Trailing Mr. Memory to his hideout, he is captured and used as a weapon against the captive JLA members, but he escapes using his own abilities and Green Lantern’s ring. The League then unmasks Memory, who turns out to be an amnesiac Batman manipulated by the true villain. By tracking the frequencies of the villain’s electronic spy devices, J’onn J’onzz and the Flash are able to capture Professor Amos Fortune.

With the villains jailed, the team returns to the Secret Sanctuary, and the full membership officially welcomes the Atom to their ranks.
