The Justice League of Earth are fictional characters, a supervillain team of the 31st Century in the DC Comics universe. They were created by Geoff Johns and Gary Frank and first appeared in Action Comics #859 (January 2008) as enemies of the Legion of Super-Heroes. Fictional team history The Justice League of Earth is a group of super-powered humans living on 31st Century Earth. They all auditioned for the Legion of Super-Heroes, but were rejected due to their powers being judged to be ineffective in battle. It was later revealed that they were actually rejected as telepathic probing revealed deep-rooted psychosis issues that would have made them potential threats. Over the time their powers mutated turning them all into considerable threats. These individuals fell under the sway of Earth-Man and his xenophobic claims that Superman was a native of Earth who worked hard to protect the planet from alien threats, in which purportedly one of Superman's greatest achievements is protecting the planet from the dreaded Martian Manhunter. The Justice League of Earth spread their ideals of distrust and hatred against aliens across Earth and were able to successfully convince the planet's inhabitants into believing them, resulting in the planet falling under the dictatorship of Earth-Man, seceding from the United Planets, and a massive persecution of aliens among Earth's people. The Legion of Super-Heroes were also branded as fugitives for perpetuating the "lies" of Superman's true origins in which the Justice League of Earth was tasked into hunting them down. The Justice League of Earth captured many Legion members and this allowed them to have their powers absorbed by Earth-Man, and he used the Legionnaire Sun Boy to turn many of the suns in the galaxy red. The Legion was being hunted by Earth-Man and his villainous cohorts, who had dubbed themselves the "Justice League of Earth". After telling the Legionnaires that Brainiac 5 sent him here, Superman, Dawnstar, Colossal Boy, and Wildfire head to his likely location: an alien holding camp. Superman and the others encounter two more Legionnaires: Night Girl and Shadow Lass, who lead them to an improvised underground headquarters from which over ten thousand extraterrestrials have escaped to their home planets. Timber Wolf and Lightning Lass are revealed to be running the interstellar "underground railroad". After a short reunion, Superman and his Legionnaire friends are discovered by Earth-Man and are attacked by the Justice League of Earth.
