Batgirl

Batgirl is a main character throughout the series. Her civilian identity is Barbara Gordon, a former member of the IT department at Super Hero High School and a student of Gotham City High School. She is the daughter of Commissioner Gordon and the BFF of Supergirl. Batgirl is very smart, in fact, she’s so smart that she got into Super Hero High based on her brain power alone, not her superpowers (similar to her mentor Batman, she doesn't have any actual superpowers, though she has plenty of skills to make up for it). When she’s not honing her detective skills, she’s figuring out cool new ways to use her incredible gadgets.
