Jane is the dominant alternate personality of Kay Challis, who suffers from multiple personality disorder. As a result of exposure to the alien Dominators' "gene bomb", each of her 64 alternate personalities have a different super-power.
Kay Challis was molested by her father since she was five years old. The first time her father molested her, she was putting a jigsaw puzzle together. Kay eventually withdrew completely and was replaced by an alternate personality answering to the name "Miranda." One Easter Sunday, Miranda was the victim of an attempted rape in a church, which triggered flashbacks of her former abuse and lead to the destruction of the "Miranda" personality and the completion of her massive personality fragmentation. Kay is transferred to a mental hospital after this happened.
When the gene-bomb went off, Jane and all of her personalities were affected; each personality gains a different power. Cliff Steele was staying in the same institution as Jane when Will Magnus asks Cliff to look after her. Cliff approaches her and she is in the rain painting. He went over to talk to her and the painting jumps out of the picture and melts in the rain. This was done by one of Kay's personalities named the Hangman's Beautiful Daughter.
In Doom Patrol, Jane's first appearance, reveals that she is not the dominant personality. Kay is the dominant one but she hasnt been out since she was five.
Jane plays a key role in stopping the Fifth Horseman. She takes control of it with the help of the Doom Patrol and the Brotherhood of Dada. However, this leaves her in a coma. Robotman succeeds in waking her up by visiting the Underground.
One of Jane's personalities, Liza Radley, tries to integrate all the personalities. Jane goes back to her childhood home, where it was the first time she was molested. While there she faces her fears and overcoms them. All her personalities become one and she loses all of their powers. She then goes to live in Danny the World, formerly Danny the Street.
Crazy Jane and Danny the Street have joined the latest incarnation of the Doom Patrol.
