New Batgirl in town!

So far, there have been five characters that have dawned the Batgirl costume. In chronological order, they were: Betty Kane, Barbara Gordon, Helena Bertinelli, Cassandra Cain and Charlotte Gage-Radcliffe. The Batgirl's I'm most familiar with are Barbara and Cassandta... more so Cassandra as I've always known Barbara to be Oracle. It looks like there's going to be a new Batgirl in August written by Bryan Q. Miller.
