Batman vs joker 2nd generation

Twenty-two

        I am about to go out on patrol when I see on the news a reporter. She says," Jj is out of control . He has taken a bus full of Gotham high teens. He is calling for batgirl. If she doesn't come he said that he will throw a can of joker gas in the bus." I look around and dad is behind me he says," go but be careful." I nod then go out on my bike. I go over to where Jj is. I pull up and see the bus on the roof on its side. I jump up and see that it is on a time detonator. All it shows is a countdown clock. I go down into the building and I see Jj in the middle surrounded by explosives. He says, "batgirl you came. I am glad you came. I will give you the detonator for the bus but you have to tell me your identity. What will it be batgirl?" I say,"how about........."
