Several once prominent adventurers found the need to assemble in order to overturn the malevolent machinations of Vandal Savage. Assisting Superman in protecting Earth-One from Savage, these heroes formed the core of the team known in the press as the Forgotten Heroes.
Consisting of Cave Carson the subterranean explorer, Congo Bill the explorer and his Congorilla alter ego, Rip Hunter the Time Master, Rick Carson the military mastermind, Dolphin the mystery maiden of the seas, and Animal Man... they were led by the enigmatic Immortal Man. Little did they know that their evil counterpart, Forgotten Villains, would cause them more problems.
Enchantress gathered her crew of cronies together in order to conquer the entire universe under a sinister triad of evil headed by herself, Kraknow and a living planet named Yggardis. When Atom-Master realized he, Poseidon and the Hunter had been duped, he quickly switched sides and usurped control of Ultivac in order to defeat his former teammates. This allowed the Heroes to swoop in for the victory after traveling through time and space, and in the course of action meeting other heroic comrades patrolling space ways in their own ways.. As had been the case with Atom-Master who joined the Forgotten Villains, his twin on Earth-Two known only as Funny Face created his fellow felons from scratch. To combat this threat, Superman and Lois Lane recruited a team of heroes who battled these crooks, in the comic strips that came to life using Funny Face's Bio-Ray projector! Much like the Bizarro projector, the creatures spawned were not living yet had the motivation and drive of those whom they were designed to imitate, as were thus cosmic twins to these imperfect duplicates spawned by Lex Luthor. While there were counterparts to both the Heroes and Villains on Earth-Two, counterparts to the former were the Freedom Fighters who soon left their world for Earth-X and the latter's dopplegangers were Villany Inc. which battled the golden age Wonder Women once.
