Jerome and Jeremiah Valeska
A cult which worships Jerome Valeska finds his body and uses a machine they stole from mad scientist Hugo Strange to bring him back to life. When it doesn’t work, the cult leader cuts off Jerome’s face and wears it like a mask. Then Jerome comes back to life, kills the cult leader and takes the mask back. Then Jerome shuts down all the electricity in all of Gotham City and people start rioting. Jerome then kidnaps Bruce Wayne and takes him to his circus which he took over to kill him. And Jerome tells Bruce what he wants is to prove that everyone is evil and that “there are no heroes in Gotham”. Jerome also tries to have Alfred Pennyworth murdered. Bruce manages to fight Jerome and beat him but he refuses to kill him even after Jerome loses his face in the fight. The police send Jerome to a hospital where he gets plastic surgery to get his face back and then put him back in Arkham Asylum.
