Barbara Gordon used to be Batgirl, but then she was shot in the spine by the Joker to give Batman ANGST. Now she's a genius computer hacker in a wheelchair who is the mastermind behind the worlds greatest heroes. The fact none of the crazy science/magic in the DCU hasn't restored her legs is a plot device.
Babs is the leader of an all female crimefighting team called Birds of Prey and despite her disability, she can still physically kick your ass. While drinking a cup of coffee. She might spill a little.
