Synopsis:
On the occasion of their third anniversary as a team, the Justice League celebrates with a party, and the original members narrate for newcomers Snapper and Green Arrow the details of the adventure that resulted in the formation of the team.

In the flashback tale, aliens from the planet Appellax came to Earth inside meteors to compete for the throne of their world, and in doing so, changed humans into weird copies of themselves. The Martian Manhunter encountered and defeated a stone giant, Aquaman battled a glass being, Wonder Woman saved Paradise Island from a mercury creature, Green Lantern combated a golden bird-like menace, and the Flash snuffed out a flame creature.

With five of the seven meteors accounted for, the super-heroes met at the sixth, only to be transformed into tree-like creatures by a wood-being – a plight from which they escaped through teamwork. Together, they traveled to Greenland, where Superman and Batman had teamed up to fight the final invader, a diamond humanoid.

In the aftermath of this adventure, the seven champions united permanently as the Justice League of America.
