|Barbara Gordon, the niece and adopted daughter of Police Commissioner Jim Gordon, graduated summa cum laude from Gotham State University with a degree in Library and Information Science. After graduating, she became the head reference librarian at Gotham Public Library.
The librarian transformation into Batgirl happened one night on her way to the policemen’s masquerade ball. Dressed in a homemade “Batgirl,” costume, she accidentally encountered the villain Killer Moth and foiled his attempt to kidnap wealthy Bruce Wayne. Barbara enjoyed the thrill and risk of crime fighting, and after modifying her motorcycle to create the Batcycle, Batgirl was born.
