2. Barbara Gordon (Batgirl/Oracle)

Barbara!!!!! Barbara is the double best. She’s so great.

Babs was born to Roger and Thelma Gordon, but when they were killed in a car crash, she was taken in by her Uncle James, who adopted her as his daughter. Having moved to Gotham, Barbara immediately became entranced with the concept of The Batman. Using her photographic memory, she learned criminology and trained in self-defense. Eventually, she was ready to make her debut, and faced off against Killer Moth, my favorite underrated Batman Villain.

From that point on, she was one of Gotham’s protectors, operating on her own until Batman took her in. She would later be tragically paralyzed by the Joker, but that didn’t stop her from being a hero. She took on the identity of Oracle, and worked with the Suicide Squad and the Justice League of America before helping to form the Birds of Prey, her longest-lasting legacy.

She’d later regain her mobility and go on to reclaim the identity of Batgirl, presently keeping Burnside safe from Gotham’s spillover.
