In the DCAU Justice League cartoon series, the two-part episode "Legends" paid tribute to the old JLA/JSA team-ups of yore when a battle with one of Lex Luthor's robots causes Green Lantern (John Stewart), the Flash (Wally West), Hawkgirl, and Martian Manhunter to be shunted into a parallel earth. There, they meet its resident heroes, the Justice Guild of America, analogues to the Justice Society of America (and a bit of the early Silver Age Justice League). *SPOILER ALERT* The League members, after helping the Guild thwart the schemes of the villains of this world, later discover that the real Guild was killed when this Earth's Cuban Missile Crisis escalated into a nuclear war that devastated the planet forty years prior. The lone mutate of the fallout, Ray Thompson (a pastiche of Snapper Carr and Rick Jones), used his new psionic reality-warping powers to recreate the world of his youth, including his heroes in the Guild (where he disguised himself as their 'mascot'). Both teams unite to stop him, and he dies under the strain of maintaining the illusion. The people of this earth then thank the Leaguers before they return home. This is my vision of what happened to this alternate Earth afterwards.
"Following the departure of the Justice League members, the residents of the parallel Earth once home to the Justice Guild of America--who made sure to make a record of the end of their forty-year 'purgatory'--began rebuilding their world. All across the world, within the span of three years, Earth-JGA finally managed to catch up chronologically and culturally with most of its counterparts in the multiverse. Sometimes the forces that shape the universes work in mysterious ways, and once that Earth was rebuilt, those same forces sought to restore the power balance left vacant by the JGA's demise. As a result, a new generation arose to restore the team's legacy:
-CID specialist Gary Alden, while investigating a crime scene at a chemical plant in Seaboard City during a storm, is splashed with a variety of chemical mixes that were struck by a bolt of lightning, giving him super-speed abilities. Inspired by the heroic sacrifice of The JGA, he becomes the second Streak, with a costume similar to a race car driver's.
-Stuntman Al Garman finds himself called to the resting place of Scott Mason, the Green Guardsman. There, Mason's long-dormant ring awakens and places itself on Garman's finger, turning him into the second Green Guardsman, only with a new weakness: the color violet.
-Circus acrobat Mick Damon, while taking shelter during a rainstorm, finds himself in the well-preserved lair of Catman. Deciding to bring the notion of nine lives to the mantle, Damon takes up the fight against crime by adopting the Catman persona.
-Jay Walter, an African-American engineer with a physics degree, finds a second lab belonging to the late Tom Turbine, challenges himself with rebuilding and streamlining his equipment, and creates the identity of Turbonaut.
-Martial artist Dana Nance, granddaughter of Donna Nance, the original Black Siren, takes up her mantle to honor her memory. It is then she discovers her gene-born sonic scream power.
When a large and intelligent alien slug by the name of Molor the Tyrant, with the ability to control.minds via an army of smaller copies of himself, arrives in an attempt at world conquest, these five disparate heroes band together to send him packing. Realizing that even with a world fresh from rebirth, threats still come in multiple forms, they decide to reform the Justice Guild of America, to act as a counter force.
Meanwhile, on the Earth Home to the Justice League, John Stewart learns that a new volume of the Justice Guild comic book is coming out....."
1. The new Guild members' back stories are loose pastiches to those of Barry Allen, Hal Jordan, Ray Palmer, Dick Grayson, and Dinah Laurel Lance respectively.
2. The story of them joining together is a pastiche to Brave and the Bold #28, the first appearance of the Justice League, with Molor being a homage to Starro.
3. Since the original Guild's members are pastiches of Golden Age heroes, I decided to make their successors homages to Silver Agers.
