  • Obsession: Jeremiah is obsessed with Bruce Wayne, seeing him as the brother that he never had. To this end, he hoped to bring the darkness in Bruce out so they could be the same.
  • Described as "Proto-Jokers",[1][2] Jeremiah Valeska and his twin brother Jerome are the precursors to the Joker. According to Gotham executive producer John Stephens, "Joker is somewhere out there, anonymous and unformed, and he's watching the actions of Jeremiah, Jerome and possibly even another one and he's adopting them as inspirations as the person he'll one day become."[3]
