Jane Doe

"Jane is a cipher. She's incomplete. Her life is empty, so she covets the lives of others. She takes their lives so she can have their lives."

- Jane Doe

Jane Doe is a supervillain in the DC Comics universe. She is an enemy of Batman and The Great White Shark (Warren White). Jane Doe is a serial killer who constantly tries to kill people and takes their identities until she is satisfied with the one she is currently using.

History
Jane Doe makes her first appearance in Arkham Asylum: Living Hell #1 - Chapter 1: Whole in the Head as Warren White's psychiatrist, Dr. Anne Carver. When she meets Warren in Arkham Asylum, he tries to bribe her to transfer him to a minimum security prison due to the abuse he is taking from the other inmates. However, he is unaware that his psychiatrist is Jane Doe. She had already destroyed Dr. Carver's paperwork and half-heartedly agrees to Warren's demands. During this time, Jeremiah Arkham (the second Black Mask) knows about Jane's activities and orders her to drive Warren even more insane. Jeremiah's reasoning for this is later revealed that he lost his pension due to Warren's corrupt business practices at his brokerage firm. Jane would eventually capture Warren and place him in Mr. Freeze's subzero temperature cell and locks it to ensure that he won't escape. She then plans on using Warren's identity to steal his funds but fails when Warren survives her attempt to kill him and becomes the Great White Shark. Great White Shark would get his revenge and takes his identity and would leave Jane Doe with severe third-degree burns.

Jane Doe, Firefly and Victor Zsasz are sent by Black Mask (Jeremiah Arkham) to attack James Gordon and destroy the Gotham Police Department in Battle for the Cowl. She is able to shoot James three times in the chest but he survives due to wearing a bulletproof vest. Jane Doe would later reappear in House of Hush when she meets withManhunter. Manhunter bargains with Jane that if she testifies against Two-Face's insanity plea in exchange her sentence will be reduced to life imprisonment instead of the death penalty. However, Jane Doe says to Manhunter that she will have to think about it due to receiving a counter offer from Two-Face the night before the meeting took place. She would later be visited by Hush at Arkham Asylum disguised as Bruce Wayne. Hush is able to convince the parole board at Arkham to release Jane Doe in order to manipulate her against Batman. However Hush's plan doesn't work out when she escapes due to her realizing what would happen to her when she would be of no further use to him.

Jane Doe would then kill Jeffrey Carter, who was a hostage Hush was going to use against Batman. She deduced that if she imitated as Carter, she would be captured and therefore let her get near to Hush and steal Hush's persona as Bruce Wayne. Jane planned to become Bruce Wayne and take control of his multi-billion dollar industry Wayne Enterprises. Unfortunately, Batman arrives and puts an end to her plan but is unable to stop her from severely maiming Hush's face to the point that he could no longer disguise himself as Bruce Wayne or anyone else ever again.

New 52
In this version, Jane Doe encounters Batman for the first time where she is found trying to steal assets from Vivian Wenner, a rich Gotham socialite who had been dead for a week. Jane Doe is able to escape Batman with the aide of Wrath (DC). Wrath then offers her a job as his inside man on the Gotham Police Department. Jane accepts and later kidnaps Harvey Bullock and uses his identity while forcing him to watch her actions on a television set up in his cell. She would become infatuated with the new G.C.P.D. psychologist Abigail Wilburn and as a result tries to kill Abigail and take her face. However, she is stopped and defeated by Batman. Jane Doe is then sent to Arkham Asylum where she plans to become Batman.
