J'onn J'onzz, who now was fighting crime in his green-skinned form, wanted to become a 'full-time' member of the newly formed Justice League. To do this successfully, he needed to be freed from his alter-ego John Jones. He decides to fake his death and join the Justice League.

This initial Justice League lineup was also the same as the Earth-One universe. It included seven of the Leagues most prominent members: Aquaman, Flash, Green Lantern, Martian Manhunter, Wonder Woman, Superman and Batman.

Mid 1970's

Sometime in the mid 70’s, the Super Friends faced their greatest “challenge” when they encountered a collaboration of villains known as the Legion of Doom. Led by criminal mastermind Lex Luthor, these super-villains sought for nothing less than total domination of the planet Earth. To accomplish this objective however, they first had to vanquish the Super Friends. They also brought in another hero unique to this reality, Apache Chief.

Luthor and his allies, which included such notable villains as Brainiac, Bizarro, Grodd and Sinestro, often used highly advanced weapons and devices to capture the Super Friends, but invariably, the heroes always triumphed. By 1979, after countless battles, the Legion of Doom eventually dissolved.
