Fan Casting The Joker in Batman And Owlman: Mystery of The Batwoman

In the final battle, Jack Luthor faces off against Superboy, Supergirl, and later Superman, while the Joker teams up with Batzarro to face Batman, Owlman, and Batwoman. When the Joker is about to kill Bruce Wayne, however, that is when Kate Kane kills Batzarro, and Thomas Wayne, Jr. tackles Dexter Dent, eventually kicking him off the roof of Lexcorp Industries. And so, Dexter falls to his death, landing on top of a car on the way down, and marking the end of his reign as the Joker.
