Meanwhile, the United States government becomes concerned that Superman will interfere in their operations, and have Mirror Master and his soldiers kidnap his father, Jonathan Kent, as leverage against him. The Justice League is left divided over Superman's actions with some embracing his new methods, while Green Lantern, Aquaman, Shazam, and other members refuse to support them and leave the Justice League. While Green Arrow takes Harley to his hideout to protect her from Superman's wrath, Superman reveals his secret identity before the United Nations and announces his intentions to bring peace to Earth, by force if necessary. Aboard the Watchtower, as the world reacts to his actions, Superman resolves to take a firmer stance on preventing death, which is supported by Wonder Woman but disavowed by Batman, believing that he will throw away his and the Justice League's ideals. Moments later, a grieving Superman crashes the interrogation, killing Joker by impaling him with his fist, ripping out his heart, much to Batman's horror. Joker is apprehended and brought to Arkham Asylum, where he reveals to Batman that, frustrated with being unable to break him, he turned his sights on corrupting Superman instead.
Before Superman can be warned, Lois' death triggers the detonation of the warhead, destroying Metropolis and killing millions of people. As the other heroes arrive and apprehend Joker and Harley, Batman realizes that they have mixed the stolen fear toxin and Kryptonite, using it to make Superman hallucinate that he is fighting Doomsday in reality, he has killed Lois. Superman eventually finds the Joker and Harley hiding on a submarine, but is attacked by Doomsday upon confronting them, and flies the monster into space. While searching the city, Flash finds the Scarecrow dead in his lab and his supply of fear toxin missing, before being killed by a trap laid by Joker. Upon hearing of Lois' capture, Superman and Batman call upon the other members of the Justice League to find her. Alongside Harley Quinn, Joker kills Jimmy Olsen, kidnaps Lois, and steals a nuclear weapon, which they connect to a heart rate monitor surgically attached to her heart. Simultaneously, Batman arrives in Metropolis in pursuit of the Joker, who has stolen Kryptonite from S.T.A.R. On Earth Twenty-Two, Superman hears a second heartbeat coming from his wife, Lois Lane, and realizes that she is pregnant.
