Re: What Bat females do you want?
Harley Quinn, for me. She is a great character in her own right: a victim of sentimentality and girlish naivety, perhaps Gotham's most tragic character given her abusive relationship with The Joker. She illustrates a side of his character that has yet to be seen in a movie; the daemonically charismatic seducer of souls. I can imagine a movie following them treating Gotham as a fairground in the craziest first date of all time.
Difficult, difficult, lemon-difficult.
