Untold Teamup Tales of the Justice League & Justice Society

As evidenced by the existence of an unaffected future for the Legion of Super-Heroes, Brane "Batman" Taylor, Bilbat"Captain Marv", and a Kamandi... there were multiple 30th century timelines set apart from one another. These heroes' realities remained separate and distinct from one another. Their realities... Earth-One, Earth-Two, Earth-S and Earth-A.D... where each their own unique location within the Mulitverse. As previously ascerted, this proves that a future timeline existed and was thus spared from the cross-contamination of a merged post Crisis on Infinite Earths singular universe, which itself would repeatedly reboot and readjust itself.

With this in mind, we can hypothesize additional untold tales of those 20th century heroes, including several annual teamups between the Justice League of America and the Justice Society of America. These involved additional teams, on both their own worlds and alternate Earths. This harmonizes with the pattern they set for decades, when the JLA and JSA encountered the Crime Syndicate of Earth-Three, the Lawless League of Earth-A, the Seven Soldiers of Victory of Earth-Two, the Freedom Fighters of Earth-X (and formerly of Earth-Two), the Squadron of Justice of Earth-S, the Legion of Super-Heroes of Earth-One, the New Gods of an adjacent Earth-One reality, and the All-Star Squadron of Earth-Two.

What were some of these teamups? Thanks to the inventive mind of Multiverse historian David Stepp, we get a glimpse into some of these amazing adventures:

• The League and Society teamup with Sentinels of Justice of Earth-Four to defend that world against an incursion by the Crime Champions, a gang of villains originally consisting of Earth-One's Chronos, Felix Faust and Doctor Alchemy and Earth-Two's Icicle, Wizard and Gambler. Evidentally, this sinister six expanded their roster to include Sentinal adversaries the Ghost, Doctor Spectro, Punch and Jewelee. To combat this, JLAers Batman, Green Arrow, and Red Tornado as well as JSAers Atom, Hourman and Starman are joined in the fight by Sentinal members Captain Atom, Nightshade and Blue Beetle as well as their ally the Son of Vulcan. The result of this confrontation undoubtedly proved better for Earth-Four than had the Crisis' "Villain War", which left portions of that world in environmental chaos unleashed by the costumed criminals and their mammoth sentient toxic weapon of war, Chemo.

• The Justice Society journeyed to Earth-One to assist the Justice League and the League's next generation protégées, the New Teen Titans, versus the malevolent Brother Blood and his Church of Blood from the nation of Zandia. Sebastian Blood possibly snatched the Powerstone, prompting the intervention of the JSA. Thanks to the intervention of these three titanic teams, led by New Teen Titans' leader Dick "Robin" Grayson and Justice Society member Dick "Nightwing" Grayson (although why the younger Dick reverted to his Robin alias rather than remain as Nightwing is unknown).

• Sinestro uses his ability to mentally manipulate others (which he has formerly used in a Brave and Bold tale when he controlled the Oan Guardians of Earth-One’s Universe while disguised as one of their own... and later when he exerted mind-control over his fellow Korugarians) to coerce select members of the Green Lantern Corps into becoming his second Sinestro Corps. Apparently, he sought to succeed where he had years earlier failed, when cloning himself a dozen time into the first incarnation of the Sinestro Corp when he and his minions invaded Earth-Two. The Justice Society's involvment in this tale indicates that Sinestro brought over these Corps men and women to Earth-Two for a repeat incursion into that world, one thwarted by the JLA and JSA led by Green Lanterns Hal Jordan and Alan Scott of those respective teams.

• In a two-part crossover, the Time Trapper recruits fellow temporal thieves the Lord of Time of Earth-One and Per Degaton of Earth-Two to ensnare the majority of the Justice League and Justice Society in a time trap in the 30th century of Earth-Two. In part two, the remaining Leaguers and Socialites journey to the 30th century of Earth-One to recruit the aid of the Legion of Super-Heroes from that era in helping them battle their old foe Trapper and his cronies, but end up settling for the Legion of Substitute Heroes who help them after defeating the Legion of Super-Villains sent by the Time Trio to thwart them.

• Finally, the Justice Society individually face off against the Crime Society, a version of the Crime Syndicate but from a different world than that of Earth-Three. This Crime Society is modeled off the Justice Lords, a team of renegade superheroes who took the law into their own hand, administering their perverted form of authoritarian justice upon President Lex Luthor and his criminal minions on their world. This Crime Society would undoubtedly have invaded Earth-Two, just as the Crime Syndicate had invaded that world and Earth-One several years earlier. Perhaps the Justice League later became involved, aiding the Society as they had versus the Syndicate.

• These are just a few examples of potential probable plotlines involving the Greatest Heroes of Earths One and Two in a future unobstructed by the calamity that fell upon the Multiverse during the Crisis on Infinite Earths!
