  • Unique Physiology: Since being driven insane and his chemical bath, Jeremiah has shown considerable strength and immunity to pain. Even with a batarang piercing his palm straight through, he only laughed.
  • Cheating Death[1]



  • 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.
  • Deluded: Since his chemical bath and subsequent decade without Bruce Wayne, Jeremiah began to lose touch with reality. He began confusing his memories with fantasy; he couldn't even remember his own name.

The showrunners have since remained vague as to whether Jeremiah becomes the Joker later on or inspires him.[5]
