She is the wife of Thomas Wayne and the mother of Bruce Wayne.
In the original timeline she and Thomas got shot by Joe Chill when the Wayne family decides to cut through an alleyway after a night at the movies. This was changed when The Flash crated a temporal boom when running back in time to save his mother. In the new timeline, her son, Bruce, was shot and killed instead of her and Thomas. This seeing her son die in front of her twisted and broke her mind, leading her to become the Joker of this timeline. She, with the assistance of her sidekick Yo-Yo, kidnapped Judge Harvey Dent and was holding him in their funhouse. This timeline is eventually erased when The Flash managed to again go back in time, this time to stop his past self.
