Selina Kyle aka Catwoman

Catwoman is Selina Kyle, a morally ambiguous character who has been an anti-hero, acting as an adversary, a crime fighter and also a love interest for Batman. Years of training have made her stealthy and agile as a world-class criminal, and her mastery of the martial arts makes her a formidable physical opponent. Although she began her career as a burglar, she has since then reformed and begun protecting Gotham City in her own style. This has led to her being almost completely accepted as a regular member of the Batman Family. She has also been a member of the Birds of Prey, the Outsiders, the Gotham City Sirens, the Injustice League and the Secret Society of Super-Villains. Her close friend Holly Robinson also acted as her successor for an extended period when Selina was out of commission. Catwoman was created by Bill Finger and Bob Kane, first appearing in Batman #1.
