While most of Batman's romantic relationships tend to be short in duration, Catwoman has been his most enduring romance throughout the years. The attraction between Batman and Catwoman, whose real name is Selina Kyle, is present in nearly every version and medium in which the characters appear. Although Catwoman is typically portrayed as a villain, Batman and Catwoman have worked together in achieving common goals and are usually depicted as having a romantic connection.
Alfred summons Thomas Elliot to remove skull fragments from Bruce's brain. Batman recovers and pays a trip to Blackgate Penitentiary to interrogate Bane on the whereabouts of the money. Bane eventually escapes and Batman strikes a deal with Amanda Waller, who allows Bane's escape so Batman can track him. Bane leads Batman to Poison Ivy's now abandoned greenhouse where Catwoman is. Waller captures Bane and returns him to Blackgate Penitentiary.
After the introduction of DC Comics' multi-verse in the 1960s, it is retroactively established that stories from the Golden Age star the Earth-Two Batman, a character from a parallel world. This version of Batman partners with and marries the reformed Earth-Two Catwoman, Selina Kyle (as shown in Superman Family #211) and fathers Helena Wayne, who, as the Huntress, becomes (along with the Earth-Two Robin) Gotham's protector once Wayne retires from the position to become police commissioner, a position he occupies until he is killed during one final adventure as Batman. Batman titles however often ignored that a distinction had been made between the pre-revamp and post-revamp Batmen (since unlike The Flash or Green Lantern, Batman comics had been published without interruption through the 1950s) and would on occasion make reference to stories from the Golden Age. Nevertheless, details of Batman's history were altered or expanded through the decades. Additions include meetings with a future Superman during his youth, his upbringing by his uncle Philip Wayne (introduced in Batman #208, Jan./Feb. 1969) after his parents' death, and appearances of his father and himself as prototypical versions of Batman and Robin, respectively. In 1980 then-editor Paul Levitz commissioned the Untold Legend of the Batman limited series to thoroughly chronicle Batman's origin and history.
