Justice League of America Vol 1 #200 - CGC 9.8

A powerful post-hypnotic suggestion turns the seven original Justice League members into mind-controlled pawns, who are forced to reassemble the seven Appellax meteorites in which the alien foes of their first adventure came to Earth.^[1] The later members of the League are alerted to the plight of their comrades when J'onn J'onzz battles Firestorm to reclaim the first meteor fragment in the JLA satellite. Former member Green Arrow, brought to the meeting by Firestorm and Black Canary, recalls the others' memories of that first case, and the new members set out to battle their teammates. The Phantom Stranger intervenes to give Aquaman a victory over the Red Tornado; Wonder Woman escapes from Zatanna on Paradise Island; Green Lantern overcomes the Atom; the Flash defeats the Elongated Man; Batman evades both Green Arrow and Black Canary; and Superman uses a robot to trick Hawkman, who is rescued from death in space only by Adam Strange's Zeta-Beam. While the other members are battling old comrades, the charter members, having no memory of the years since the League's formation, see their former teammates as unknown villains, and thus are not held back in their efforts to battle them. While the defeated members rendezvous with Firestorm and Snapper Carr aboard the satellite, the mesmerized original members meet at the site of their first headquarters, only to have the gathered meteorites erupt with the seed-clone duplicate forms of the villainous Appellax aliens.

Their memories restored by shock, the JLA combats the aliens, but is soundly beaten. They then join forces with the other members to seek out and destroy the seed-clones in teams: Batman, Black Canary, Green Arrow, Hawkman, Superman, Wonder Woman, and Zatanna overcome the wooden, crystal, and mercurial creatures; Aquaman, Elongated Man, Flash, and Red Tornado battle the glass and fire beings; and Atom, Firestorm, Green Lantern, and the Martian Manhunter take on the stone giant and the rock successfully. With the menace ended, Snapper Carr and J'onn J'onzz take their leave, and Green Arrow reconsiders his earlier decision, rejoining the team as a regular member.
