Jane Doe makes her live-action debut in the Gotham episode "Nothing's Shocking," portrayed by Sarah Pidgeon. This variation of the character, named Jane Cartwright, is a woman who made a testimony about her mother Victoria shooting her abusive husband. While incarcerated at Arkham Asylum, she was taken below to the Indian Hill facility and experimented on by Hugo Strange, gaining her shapeshifting powers. Under the psychological delusion that her real face had been hideously disfigured by the experiments, she wore a mask at all times. After escaping, Jane sought revenge against the police officers who had put her mother away, and started by killing detectives Boggs and Lewis at the Sirens while posing as Dix. When James Gordon and Harvey Bullock questioned Dix at his home, Jane arrived and attempted to kill him, fleeing after Bullock removed her Dix disguise. Gordon and Bullock initially suspected Basil as the killer. When hiding out at her family home, Jane ambushed and posed as a police officer that accompanied Gordon and Vanessa Harper. When Gordon attacked her, Jane regressed back to normal as she didn't want Gordon to see her face. At the Gotham City Police Department, Jane stated her side of the story and how she got her powers while stating that Jane Cartwright had "died in Arkham." When Gordon stepped out, Jane used her powers to free herself from her restraints. She killed Dix while posing as Bullock, and escaped the precinct while disguised as Barbara Kean. Bullock confronted Jane at her house. After being persuaded to remove her mask by Bullock, Jane stated that only one of them would leave the room alive, and raised her gun. This forced Bullock to put Jane out of her misery.
