Superman/Batman: Public Enemies

United States President Lex Luthor uses the oncoming trajectory of a kryptonite asteroid to frame Superman and declare a $1 billion bounty on the heads of the Man of Steel and his "partner in crime" Batman. Super heroes and super villains alike launch a relentless pursuit of Superman and Batman, who must unite - and recruit super help - to stave off the action-packed onslaught, stop the asteroid, and uncover Luthor's devious plot to take command of far more than North America.
