Barbara Gordon aka Batgirl aka Oracle. Of all the of the members of the Bat-Family, I think she's has the potential to succeed Batman and also the smartest (second to Batman).
Sure.. I guess. So long as you like the supers. Anyways do you just dislike all other members of the batfamily or select members? Where does it end? Dick? Jason? Alfred? Tim? Helena? Kate? Luke? Heck.. Carrie? Etc
