Background: 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.
Context: In June 2016, the DC Rebirth event relaunched DC Comics' entire line of comic book titles, in which Catwoman has a prominent role in the third volume of Batman. In December 2017, DC Comics ended the Rebirth branding, opting to include everything under a larger "DC Universe" banner and naming, and Catwoman continues to be featured in the third volume Batman. The series reveals Selina's origin through a series of flashbacks and letters exchanged between Bruce and Selina. Her parents died when she was young, and she hardly remembers them. She is sent in the Thomas and Martha Wayne Home for the Boys and Girls of Gotham, and even after being placed in various foster, she would escape to return to the orphanage.  Eventually, Selina becomes Catwoman. During one of her heists, she is approached by the Kite Man to aide the Joker in a gang war against the Riddler, which she refuses. She later aides Batman, with whom she already has a romantic relationship, to spy on the Joker. She is shot from a window, but is unharmed. At some point in the future, her childhood orphanage is bombed by a terrorist group called the Dogs of War. Batman reluctantly arrests Catwoman after all 237 of them are killed, despite Catwoman's insistence on her guilt.  Her first appearance is in Batman #9, where she is revealed to be imprisoned in Arkham Asylum for the alleged murders of the Dogs of War. Batman is determined to prove her innocence, and makes a deal with Amanda Waller to get her off death row in exchange for her help on a mission to Santa Prisca. The mission to find Psycho Pirate is a success, and Batman and Catwoman return to Gotham City. Before Batman can return her to custody, she escapes. Batman investigates the murders of the terrorists that she has been charged with, and deduces that it was in fact Holly Robinson who committed the murders after the terrorists burned down the orphanage she and Selina were raised in. After being attacked by Holly Robinson, Batman is rescued by Catwoman.  Bruce proposes to Selina in Batman #24. In issue #32, Selina asks Bruce to propose to her again, to which she says, "Yes."  The two leave Gotham for Khadym, where Holly Robinson has fled to, to clear Selina's name.  Batman Annual vol. 3, #2 (January 2018) centers on a romantic storyline between Batman and Catwoman. Towards the end, the story is flash-forwarded to the future, in which Bruce Wayne and Selina Kyle are a married couple in their golden years. Bruce receives a terminal medical diagnosis, and Selina cares for him until his death.
