Barbara Gordon

The first Batgirl. She quit being Batgirl when she was shot by the Joker and paralyzed from the waist down. She then became a new hero known as Oracle, fighting crime behind the scenes, and organized a crime-fighting team along with Black Canary called the Birds of Prey. However, DC Comic's reboot in 2011 has put her back into action as Batgirl. She's one of the smartest heroes in the DCU, and served as a mentor for Stephanie Brown and Cassandra Cain, the two other Batgirls.
