Intro. This Bruce Wayne not only lost his hometown, he also lost his Butler Alfred Pennyworth due to a plan that The Joker carried out. This plan consisted of the Joker making Batman believe that he had murdered Alfred, all thanks to the Scarecrow's Fear Toxin. The Joker made Bruce believe that he had killed Alfred, but in reality Alfred was still alive and Bruce killed him believing that he was The Joker. And with Alfred, Gotham City would perish due to a Nuclear Bomb that destroyed everything. Bruce Wayne lost a lot that day, his butler, his city and some friends............ That day. The Joker achieved what he was looking for, he managed to corrupt Batman But of course, the Joker was not spared the consequences, because Bruce, full of hatred and anger, killed the Joker in front of Kal El and Diana of Themisyra. That day, only Batman was left and Bruce Wayne was lost forever ............
