tower is rigged with bombs that will detonate if he moves too fast. He then tries to force Superman to kill himself so that Prometheus will allow civilians to leave, on the grounds that Superman was too powerful for him to devise a means of killing. Prometheus is then caught off guard by the anti-hero Catwoman, who had also infiltrated the tour group, allowing the heroes time to recover. Steel infects Prometheus's systems with a virus. Admitting he lied about the bombs, Prometheus escapes to the Ghost Zone before he can be captured. Prometheus appears briefly during an encounter between the JLA and the Avengers and skirmishes with Captain America while using Batman's skills, but Captain America easily defeats him. Prometheus returns as a member of Lex Luthor's second Injustice Gang. During the confusion caused by the arrival of the weapon Mageddon, Prometheus is able to use a White Martian space vessel abandoned in the Ghost Zone to infiltrate the Watchtower and attack Oracle. Oracle escapes, with Prometheus's helmet being damaged in the process. The villain retrieves his original helmet (lost during the first battle with the JLA) and battles Batman once again. Prometheus is neutralized when Batman sabotages his helmet, overriding the information on the disc Prometheus uses to upload his combat skills and replacing the data with the physical skills and coordination of Professor Stephen Hawking. Batman prevents fellow member Huntress from killing Prometheus. Batman and Martian Manhunter take Prometheus into custody and arrange to reduce Prometheus's brain to a mentally disabled state in order to permanently end his threat, reasoning that his skills and training mean that no jail could hold him under conventional circumstances. Upon Martian Manhunter's death at Libra's hands, Prometheus's mind was restored and he tracked down Chad Graham, killing his would-be protégé and maiming/murdering members of the Blood Pack super-hero team. Cry for Justice A spate of superhero deaths (Freedom Beast, Gloss, and Tasmanian Devil) and attacks on others (Barry Allen, Batwoman, and Crimson Avenger) is revealed to be the work of the true Prometheus. The villain impersonates Freddy Freeman and gains access to the JLA satellite, which in turn allows Prometheus to place teleportation devices in the home cities of various heroes which will "strand" them in various places in the past and future, as revenge for the years that he spent with his mind damaged. Prometheus also maims Roy Harper after
