If batgirl makes an appearance in Margot Robbie's movie (I ask this because she's mentioned wanting to have batgirl appear in some capacity), would you want it to be Barbara Gordon, Cassie Cain, or Stephanie Brown?

I would say a tie between Barbara and Cass. Barbara is an easy explain, she’s Gordon’s daughter. Cass requires a bit more set-up, and Stephanie even more. But the absolute stone-cold COOLNESS of Cass would be great onscreen.
