In the Comics “A Killing Joke”
The Joker shot Barbara Gordon, AKA Batgirl, right in front of her dad.
This attack paralyzes her and made her lost the ability to walk. She also Mentally suffered from trauma of this experience.
It is one of the darkest stories in Batman history but also the most hopeful. Barbara has no choice but retires the mantle of Batgirl. She becomes paraplegic, but it didn’t stop her from fighting crime.
She have genius level of skills in various sciences and she is a very prolific hacker. She had assisted multiple superheroes on their missions while contacting her via earpiece and a headset on her computer. Do not underestimate her just because she sits on a wheelchair. She still have her prolific combat ability. The Oracle can still fend for herself. Barbara goes with the new mantle, Oracle. Oracle is first adapted into live action at the Birds of Prey Tv series.
The third season of Titans will focus on how Nightwing AKA Dick Grayson left the Bat family. That is when Oracle will enter the story. Savannah Welch got casted to play Oracle in Titans. She is a real life amputee so she can tell the story of the Oracle in a more genuine way because she experience the same struggle. At certain point of the story, Barbara will be able to walk again so that could be a problem, but it won’t because Savannah can just simply wear prosthesis if we will get to that point of the story. There will be flashback scenes when can still walk and Savannah will be able to pull off those scenes.
Savannah is currently going through Combat training as a preparation for the role. Expect a fight scene while she is riding a wheelchair.
