At some point, Catwoman entered into a romantic relationship with Batman. This allowed her to steal some of his nanotechnology and weave it into her whip, making it indestructible.[1] Catwoman was eventually defeated and arrested by Batman.[2]
In the DC comics, Catwoman is Selina Kyle, a morally ambiguous character who has been an anti-hero, acting as an adversary, a crime fighter, and a love interest for Batman. She was created by Bill Finger and Bob Kane, first appearing in Batman #1. (1940)
It is currently unknown if Arkham Asylum patient S. Kyle and Catwoman are the same character.
