Katherine “Kathy” Kane was a Gotham socialite who first appeared in comic books in 1956. Kathy, a character created by Edward Hamilton and Sheldon Moldoff, was an heiress who was abducted by the caped crusader. She chose to combat crime in Gotham on her own, and she did it by disguising her bat-accessories as common goods. She disguised her equipment as lipstick, hairnets, and beauty compacts in a utility purse instead of a belt. ¹⁾

Kathy Kane was originally obsessed with Batman, which inspired her to replicate his crime-fighting abilities. When Batman discovered the lady beneath the mask's identity, she became an extension of the Bat Family. Kathy and Bruce were once in a relationship, but it didn't last. Despite the fact that she hadn't appeared in a comic for years, Catwoman remained the more popular love interest.²⁾

Barbara Gordon may be the most well-known Batgirl these days, but when authors were intent on expanding the Bat Family, another Bat-Girl came first. Kathy's cousin Betty came to see her. When she did so, the younger girl discovered her aunt was a superhero. Rather of merely attempting to persuade Betty to maintain her secret, Kathy educated her. Kathy assumed that if Betty realized how tough the job was, she would be disinclined to pursue a career as a cop. Betty proved her aunt incorrect, becoming Bat-Girl and her aunt's first official sidekick.
