Superman #271

In "The Man Who Murdered Metropolis!", Superman faces a chilling threat when Brainiac unleashes a mirror image of Metropolis from the sky, threatening to obliterate the real city upon collision. With the help of WGBS reporters Clark Kent, Steve Lombard, and Melba Manton—and the reluctant aid of media mogul Morgan Edge—the Man of Steel must outwit the alien villain’s twisted logic before the city is destroyed.
