Biography
The Justice Lords are an alternate version of the Justice League from a parallel Earth. The roster of the Justice Lords was the same as the original DCAU Justice League — an alternate Batman, Green Lantern, Hawkgirl, Martian Manhunter, Superman, and Wonder Woman — with the exception of The Flash, because the Flash from their universe had been killed.
The Justice Lords' world diverged from that of the Justice League when their Lex Luthor was elected President of the United States. The Flash was executed personally by Luthor for unknown reasons, and Luthor's policies eventually resulted in the country "being on the brink of a war that could destroy the whole planet" according to Superman. The alternate Batman, Superman, and Wonder Woman decided to try to stop the impending war, storming the White House and confronting President Luthor, who threatened a nuclear launch. After Luthor goaded the alternate Superman, that no matter how many times Superman sent him to prison Luthor would find a way back into power all over again in an unending cycle, the enraged Kryptonian targeted Luthor with heat vision and killed him. This decision led to far-reaching consequences, as Superman decided he liked this new brand of "justice". Soon, the other Lords lost faith in humanity's ability to do what was right, as well as their own moral compasses.
The initial act of staging a coup eventually led to the Justice Lords taking over the world's governments and ruling with an iron fist. Using their satellite base for global surveillance, the Justice Lords went on to suppress free speech, outlaw elections, impose curfews, and eliminate all crime by lobotomizing all criminals and supervillains (to the point of having a man arrested for complaining about the food quality and incorrect calculation of cost at a restaurant). Although they justified their behavior to the masses as "temporary," and to each other as for the good of the people, it amounted to tyranny in the eyes of the Justice League.
