Fan CastingSuperman vs Batman: Injustice

the Joker and Harley Quinn kill Jimmy Olsen, kidnap Lois Lane, and steal a nuclear weapon, which they connect to a heart rate monitor surgically attached to Lois' heart. Upon hearing of Lois' capture, Batman calls in all Justice League members to find her. The Flash finds the Scarecrow dead in his lab and his supply of fear toxin missing, before being killed by a trap laid by Joker. Superman eventually finds the Joker and Harley hiding on a submarine, but is attacked by Doomsday upon confronting them, and proceeds to punch the monster into space. As the other heroes arrive and apprehend the Joker and Harley, Batman realizes that they have mixed the fear toxin with Kryptonite, and used it to make Superman hallucinate that he is fighting Doomsday; in reality, he has beaten Lois to death. Batman tries to warn Superman, but it is too late; Lois' heartbeat stops, and the nuke detonates, destroying Metropolis and killing millions of people
