Batgirl is the name of several fictional characters appearing in comic books published by DC Comics, frequently depicted as female counterparts to the superhero Batman. Originally created by Bill Finger and Sheldon Moldoff, a character that is (arguably) considered by some to be the first incarnation of Batgirl, the "Bat-Girl" Betty Kane, debuted in Batman #139 (April 1961) as the Robin-like sidekick to Batwoman. Following the promotion of Julius Schwartz to editor of the Batman-related comic book titles in 1964, the Bat-Girl character was removed from publication (along with Batwoman) and replaced by the "new" Batgirl Barbara Gordon, police commissioner James Gordon's daughter, in late 1966. This version of Batgirl was introduced in Gardner Fox and Carmine Infantino's Detective Comics #359, entitled "The Million Dollar Debut of Batgirl." After Gordon was shot in the spine by Joker, she became Oracle and the new Batgirl was Cassandra Cain. After awhile, Barbara recovered from his injury and she returned to her old alias as Batgirl.
