Batgirl, Vol. 3 #1 (2009)

Batman: Reborn - Batgirl Rising, Point Of New Origin, Part 1
The new Batgirl trying to make sure she's noticed in Gotham City while trying to prove she can fill former Batgirl Cassandra Cain's impressive shoes. The issue starts with a scene out of Fast and Furious with some illegal street racing until Batgirl shows up and bursts up the scene. She's sloppy, as Batman and Robin watch her from afar. Damian notes that this isn't the former leader of the League of Assassins. No, she's "not as good as the other Batgirl", states Dick. Whether Dick means Barbara Gordon or Cassandra Cain is unclear, but we soon learn who she is.
