- I haven't finished my jigsaw. I haven't.
- — Kay Challis src
Kay Challis was molested by her father Arthur since she was five years old. The first time her father molested her, she was putting a jigsaw puzzle together; this would be an important symbol in her future. Kay eventually withdrew completely and was replaced by an alternate personality answering by the name "Miranda." One Easter Sunday, Miranda was the victim of an attempted rape in a church, triggering flashbacks to her former abuse, the destruction of the "Miranda" personality and the completion of the massive personality fragmentation. Kay was committed to a mental institution soon after.
When the Dominators' gene-bomb went off during Invasion!, Jane and all of her personalities were affected. Each of her personalities gained a different power (e.g. Black Annis has retractable claws, Flit can teleport, etc.). Cliff Steele was staying in the same institution as Jane when Will Magnus asked Cliff to look after her, which led to Jane becoming a member of the Doom Patrol.
Eventually Jane made a pilgrimage back to her childhood home, facing her own traumas and overcoming them. This brought peace to her inner turmoil, and for the first time in her life she finally felt like she could live a happy, productive life with her condition. After this incident, Jane believed that none of her alters had retained their superpowers.
Upon returning to the Doom Patrol, Jane was attacked by the Candlemaker and thrown into another dimension, similar to the real world, where she was interned as a schizophrenic and treated with shock therapy. Cliff eventually rescued Jane from the other dimension and lived with her on Danny the World.
It was later revealed that Jane's alters still had possession of their powers despite Jane believing otherwise, and as a result Cliff left her and returned to Earth. The two separated due to constant arguments, mostly Cliff's fault, and because Cliff felt afraid of her.
Danny later found himself subjected to mandatory gentrification at the hands of a group of pan-dimensional gentrifiers, reconfiguring himself into Danny the Brick to escape them. He and Jane sought refuge with the Doom Patrol, now resident on Oolong Island, but were followed by the gentrifiers, who saw the brick as their rightful property. Danny assumed a new form as Danny the Bungalow, and the brick was returned to the gentrifiers, who promptly departed. Jane remained on Oolong Island with Danny the Bungalow.
- Multiple Personalities: Kay Challis has 64 personalities, each with its own unique ability. Crazy Jane's personalities are organized in a mental subway grid called the Underground. Each personality has its own 'station,' which appears to serve as home when they are not in control. In the lower section of the Underground is the Well, where the personalities go to destroy themselves; this is where Miranda was killed and where Jane attempted to destroy herself. The Well houses the Daddy persona of Jane's mind.

- Multiple Personalities
- Misandry: While reminded of her trauma of being raped twice, Jane can sometimes experience an episode of uncontrollable hatred of men, which lead to her killing a male police officer in a church for even talking to her. 
- The name Crazy Jane comes from a Victorian era painting by Richard Dadd, created shortly before his death. The in-universe explanation for this is that Challis was a graphic designer, and naturally took inspiration from the artwork. Interestingly enough, at the time he painted it, Dadd was confined to a mental institution for the paranoid schizophrenia that plagued him most of his adult life.
- There is also a series of poems written by William Butler Yeats featuring Crazy Jane as the title character, and Kay Challis is shown to be aware of these. Although she seems to have them memorized, how much influence they've had on her is unclear. They include Crazy Jane and Jack the Journeyman, Crazy Jane and the Bishop, Crazy Jane Grown Old Looks at the Dancers, Crazy Jane on God, Crazy Jane on the Day of Judgment, Crazy Jane on the Mountain, Crazy Jane Reproved, and Crazy Jane Talks with the Bishop.
