Katherine "Kate" Kane is Renée Montoya's former lover and heiress to one of the wealthiest families in Gotham City, owning that which the Wayne family does not. Renee refers to her as "Katherine the younger" and asks Kate to help find the connection between the Kanes and the address 520 Kane Street. While still upset from their breakup, Kate agrees to help Renee, but punches her after Renee mentions their prior relationship. Renee suggests they once loved each other, and Kate tells her to leave. Not long after that, Batwoman is shown to be observing Montoya from the rooftops as Renee converses with the Question (in his guise as "Charlie") in an alley. Kate meets with Renée and Charlie in Gotham Park and confirms that the warehouse was being leased by Ridge-Ferrick until six weeks ago. Renee refuses to tell Kate what's going on saying that she doesn't owe Kate anything, which shocks Kate and prompts her to tail them as Batwoman. When Renee and the Question break into Ridge-Ferrick's Gotham offices, they are attacked by Whisper A'Daire's shapeshifting minions, and Batwoman arrives to rescue them. Making quick work of two monsters, Batwoman stops Renee from shooting the third, instead kicking the monster out a window. Batwoman informs them the police are coming, asks that she not be mentioned, and leaves. After Renee learns that the Book of Crime, a sacred text of Intergang, contains a prophecy foretelling the brutal murder of the "twice named daughter of Kane," she and the Question return to Gotham. They contact Kate by flashing a Bat-Signal, and the three join forces to avert Intergang's plans. As Kate continues the case, she is joined by Nightwing, who has recently returned to Gotham and becomes infatuated with her. On Christmas Eve, he gives her an 'official' Batarang. She also celebrates Hanukkah with Renee, and the two kiss shortly before Christmas. Intergang realizes that the image of Batwoman in the Crime Bible and the cited "twice-named daughter of Cain" were one and the same, and ransack Kate's apartment, kidnapping her with the intention to sacrifice her. Renee finds her, seemingly too late to save her, as during the fight, Kate pulls the knife out of her own chest to stab Bruno Mannheim and then collapses in Renee's arms. Kate survives her wounds after Renee stops the bleeding in time, however, and as she recuperates in her Penthouse, Renée, dressed as the Question, shines the batsignal into her apartment and asks "Are you ready?" One Year Later One year after the start of 52, the Penguin suggests Batman bring a date to the opening of his club, asking, "Why don't you bring that new Batwoman? I hear she's kind of hot." Batwoman has most recently appeared in Countdown 39. She appears after Renee Montoya confronts Trickster and Pied Piper, having trailed them from Penguin's Iceberg Lounge nightclub. In her civilian identity as a socialite, she is acquainted with Bruce Wayne and is friends with a doctor named Mallory, who treats the Question's cancer and later Kate's stab wound. Kate is also Jewish, and celebrated Hanukkah with Renee. Her familial relationships are unknown. It is unconfirmed whether or not Kate Kane is related to the New Earth versions of Kathy Kane and Bette "Flamebird" Kane, although Montoya alludes to there being an older Katherine Kane in Kate's family.
