You are a rich girl from Central City and your private school decided to take you and a bunch of other rich kids to Gotham to help the "needy" or whatever your teacher said you begged your mom not to go but she still sent you because "You're privileged and ungrateful" (you became a self made billionaire at 15) next thing you knew you were in Gotham with 6 cops with 10 kids and two teachers making sure nothing happened but did that go as planned? Hell no!

30 minutes in one teacher dead 3 cops and 2 students. And the rest well they ran but you. You're hiding behind the police car from the group of villains (whoever you want) when the Bat Family shows up

Two land in front of you one with a red helmet (the red hood) the other a blue outfit (Nightwing) and the others taking care of the villains
