“What makes the runaway success of the Oracle character more remarkable is that it began during an era where bleak heroes with big guns were ruling the day. Without much fanfare, Barbara Gordon has become the most popular handicapped character since Charles Xavier. In fact, Oracle’s nature as a handicapped superhero and a role model is almost never mentioned by the company or fans…There WAS some idea of her being a role model, I think… We wanted her to cope with what had happened to her and becoming, in many ways, more effective as Oracle than she ever was as Batgirl. And we knew that others with disabilities might look at her and feel good reading about her…I don’t think people ‘dance around’ her disabilities as they don’t want to focus on them, but on her character. These shouldn’t be stories about a disabled person; they are stories about a compelling fascinating character who HAPPENS to be in a wheelchair and I think that’s correct. Barbara isn’t her handicap; there’s more to her than that.” - John Ostrander
“Well, the story where Barbara was shot and crippled, she was really nothing more than a prop, a common treatment of female characters at the time. Again, there was a belief that there was no such thing as a female comics reader…people like you and I didn’t exist in their minds.
But the brilliant Kim Yale and John Ostrander picked up the character and made her into a brilliant master computer operator and one of the most fascinating characters in comics. From there, Chuck Dixon did wonderful things with her in his Birds of Prey run.
She’s fantastic because even just sitting in a chair in a dark room by herself, she’s tremendously compelling. The DCU without her would be a much less interesting place.” - Gail Simone
