The Justice League and Justice Society each had a large membership roll, second only to their fellow fearless friends of other eras, the Legion of Superheroes and the All-Star Squadron. In their pre-crisis histories, they each had exactly twenty-two members, however there were others affiliated with these teams. For the Justice League, among those twenty-two were the Phantom Stranger, who never officially accepted membership. Stranger's counterpart was Spectre who was a founding member of the Society. The Stranger would visit the parallel world known as Earth-Five, while Spectreventured to Earth-One for a few years aiding that world's League before returning to his native world during the Crisis on Infinite Earths to once more aid the Society.
Sargon became an honorary member of the League just prior to the Stranger's inclusion as a member. Two other honorary members were Snapper Carr and Edmund Blake. Carr as Star Tsar had a doppleganger in Society member Sylvester "Star-Spangled Kid" Pemberton, while Blake's counterpart was fellow youth Charlie Parker. Blake had revealed that his long association with the Society during the 1950's culminated in his being awarded honorary membership status, while Parker's was more brief. Other heroes who aided the League in an honorary capacity were Adam Strange and Metamorpho. Those who aided the Society though not in an offical capacity were the original Red Tornado (Ma Hunkel) and the Thunderbolt. While the golden age Superman and Batman were honorary Society members in the 1940's, the silver age versions were irregular attendees in the League's early days.
Some members departed each team only to return later, such as the Martian Manhunter, Wonder Woman, Hawkman, Batman, Green Arrow and Hawkgirl of the League as well as the Flash, Green Lantern, Hourman, Sandman, Starman, Doctor Fate and the Spectre of the Society. There were also the parallel phases on each team, with the original seven of the League and first ten of the Society, followed by their initial recruits Green Arrow and Johnny Thunder. Some were recruited for emergency cases such as the League's Metamorpho and Sargon and the Society's Wildcat and Mister Terrific. As the years rolled along, more members would join these prestigious paragons of protectors. Then a new generation of heroes in the League's Detroit team of Steel, Vibe, Vixen and Gypsy and the Society's All-Star Super-Squad of Star-Spangled Kid, Robin, Power Girl and the Huntress. Regardless of who joined, the goal of each team...Justice... never falted nor failed! Nothing less would be expected from their Worlds' Greatest Teams!
