Batman 4: Injustice

With liberty, injustice for all

Batman, Tim Drake, Black Lightning, and Wally West investigate a string of crime lab thefts in Gotham, Central City, San Francisco, and Metropolis. Jack Napier has become the Joker once more, and even more unhinged than ever. He has kidnapped Lois Lane as well as Scarecrow and Poison Ivy, broken into crime labs and is developing a new toxin that will trick Superman into attacking the woman he loves more than life itself. His actions against Lois and the Joker will trigger a bitter rift with Batman - who ends up protecting the Joker from the Man of Steel's wrath - that will reverberate violently throughout the superhero community and the country. In the end, Joker/Napier agrees to be placed in a newly reorganized Arkham Institute, headed again by Huge Strange but, as the post-credits scene shows, Harley Quinn enters the room and immediately kills him and (because he threatened her and Ivy) plans her own revenge on Joker.
