you saw Bat man and Robin and was inspired. You wanted, no needed to help people. The only problem was that your father, the police commissioner, would never let you be an officer. He thought you were too short. But you had to prove him wrong. So you began to make your own Bat costume

It wasn't as authentic as the real one, made from fabric and pieces you could order on eBay. However when you started fighting crime, Bat man took interest in you, and by proxy, Robin.

You were forced to prove yourself to them, which you did, and you were officially a part of the Bat family. It was just unfortunate you were forced into the name Batgirl as opposed to batwoman, but beggars can't be choosers

The worst part of the job wasn't the criminals or the danger, it was the bratty sidekick you had to patrol with

He didn't think you could do it. And he had every excuse. "You're just a girl" "you're too short" he used them all

Well, now you were in a Mr Freeze hideout, getting ready to pounce at his goons whenever they appear

"Just be quiet and let me handle it, okay?"
