Black Siren

The Justice Guild of America is a superhero team featured in the Justice League animated series two-part episode Legends, a homage to the Golden Age Justice Society of America, and to a degree the Silver Age Justice League of America.

At the climax of a fight between the Justice League and a giant robot remote-controlled by Lex Luthor, it falls over, threatening to crush The Flash, Green Lantern, Hawkgirl, and J'onn J'onzz. The Flash tries to stop the damaged robot falling onto the other Leaguers by running so fast that he creates a tornado-like vortex just as the robot's energy core explodes. This causes them to accidentally end up on a parallel Earth existing in a different vibrational frequency from the Justice League's own. They end up in Seaboard City, an idyllic 1950s locale, that more than a little resembles Pleasantville or other such havens. It also bears more than a passing resemblance to The Village of The Prisoner and features an ice cream van which plays "Pop Goes the Weasel", a tune regularly employed on that show.

There they meet the Justice Guild of America members - Tom Turbine, The Streak, the Green Guardsman (not to be confused with Green Guardsman of Amalgam Comics), Black Siren, Catman, and their sidekick / mascot Ray Thompson. They first fight when Green Lantern and the Flash stop a robbery by Justice Guild enemy the Music Master, and the Guild mistakes them for the thieves. However, after the Streak sees Flash save Ray from pieces of a falling building, he realizes the League aren't criminals and stops the fight. The Guild were comic book characters on the Justice League's Earth about whom Green Lantern read as a child. He claims without them he may not have the ring today, as the comics taught him to be a hero. J'onn J'onzz hypothesizes that the JGA writers were psychically tuned in to their Earth during flashes of "inspiration"; this is a nod to the explanation Gardner Fox provided for the JSA/JLA link in his September 1961 story Flash of Two Worlds in which the Barry Allen Flash of Earth-One encounters Jay Garrick, his Earth-Two counterpart. They help the JGA fight a group of their enemies, the Injustice Guild of America, who are based on Golden Age DC supervillains. The IGA engage in a scheme to pull off a series of crimes based on the four elements of earth, air, water, and fire.
