She is the wife of Thomas Wayne and the mother of Bruce Wayne.
Joe Chill murders Bruce Wayne, rather than the boy's parents. Martha Wayne was so traumatized by the event she cuts open her cheeks to create a faux smile. Months after the murder, Martha tracks Chill down and murders him with a hammer. Her husband Thomas wished to gain revenge for his son's murder and becomes this reality's version of Batman. She is working with her own version of Harley Quinn called Yo-Yo. She becomes the archenemy of her husband, Batman.
She kidnaps the twin children of Judge Dent. She tricks Chief Gordon into shooting Dent's daughter by taping her mouth shut, guns to her hands, and disguising her as the Joker. Before Batman confronts her, she slashes Gordon's throat. After Gordon's murder, Batman turns-up to face his Estranged wife. 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 Judge Dent and was holding him in their funhouse.Batman tells her he has discovered a way to rewrite history so Bruce was never killed. He told her about Barry Allen and how he helped him restore his powers. Martha with this knowledge is shocked to learn her son will become the Batman, she runs to her death off a cliff near Wayne Manor. This timeline is eventually erased when The Flash managed to again go back in time, this time to stop his past self.
