Catwoman is a fictional character appearing in American comic books published by DC Comics, commonly in association with the superhero Batman. Created by Bill Finger and Bob Kane, the character made her debut as "the Cat" in Batman #1 (June 1940). Catwoman, whose real name is Selina Kyle, has been Batman's most enduring love interest and is known for her complex love-hate relationship with him. As a Gotham City burglar, Catwoman typically wears a tight, one-piece outfit and uses a bullwhip for a weapon.

In 2011, DC Comics relaunched all titles, deemed the New 52, which rebooted the DC Universe continuity. Catwoman's monthly title now focused on Selina's earlier days as Catwoman, but not her origins. The series begins with Selina frantically escaping from unknown masked men who are invading her apartment. After flitting from rooftop to rooftop, Selina looks back just in time to see her apartment blown apart by explosives. She turns to her informant, Lola, who often supplies Catwoman with information and various jobs. In this instance, Lola tips Selina off to an unoccupied penthouse where Selina can lay low for a few weeks, as well as a job stealing a painting from Russian mobsters. For this job, Selina infiltrates a Russian club by posing as the bartender. There, she recognizes a man who murdered a friend of hers, and she takes her revenge. Once her cover is blown, Selina dons her Catwoman outfit and fights her way out of the club. It is revealed through Selina's inner monologue that she and Batman are lovers, and the premiere issue ends with the first sex scene between the two. Her revised origin in Catwoman #0 draws from Batman Returns.  Catwoman is later confronted by Steve Trevor, who offers her a spot on Amanda Waller's new Justice League of America. Selina initially refuses, but accepts the offer after Trevor promises to help her track down a woman who has apparently been posing as Selina. It is later revealed that Catwoman was chosen specifically to take down Batman should the JLA ever need to defeat the original Justice League. The teams eventually come into conflict in the publisher's "Trinity War" crossover.  In the Earth-Two continuity, Selina Kyle and Bruce Wayne are married, and their daughter, Helena Wayne, is that universe's Robin. In this universe, either Selina has reformed or was never a supervillain in the first place. It is revealed in issue #0 of Worlds' Finest that this Selina was killed while trying to stop what she believed was a human trafficking ring.
