History: (JLA #9-12, 14, 15) - Lex Luthor used the Philosopher Stone to brainwash Jemm and made him nudge the minds of a number of villains so that they would be willing to work for Luthor as the Injustice Gang. He told them they wouldn’t be having another brawl with the JLA, they would defeat the heroes using corporate strategies like gathering information, recruitment and shaking their confidence in their leader. Lex designed the JLA Revenge Squad, hard-light duplicates, and sent them to wreck havoc in Star City. The Revenge Squad gathered information about the JLA and their team fighting style before being recalled. The Gang lured Superman and Martian Manhunter to a duplicate of the Injustice Gang satellite hq, and trapped them in a maze that was a manifestation of Joker’s mind. Circe then approached Green Arrow and tried to lure him away from the JLA, bringing him to the Gang’s hq. Lex Luthor patched in a transmission to the Watchtower, revealing himself as Aztek’s Q Foundation’s benefactor. The Gang teleported nuclear warheads aboard the Watchtower, and Luthor told Aztek he’d start working for the Gang or die. Aztek refused and disarmed the bombs. The JLA found the Injustice Gang satellite, thanks to Arrow, who’d only pretended to betray the JLA, and Mirror Master, who was working for Batman, who’d paid him more than Lex. The JLA defeated the Gang and blew up their satellite. Joker was got the Philosopher’s Stone, and prepared to use it on the JLA, but Martian Manhunter temporarily turned him sane. Lex convinced Joker to use the Stone to undo the deaths the JLA Revenge Squad caused in Star City, ensuring that Lex couldn’t be charged with any crime.
