Talia (Batman Begins)
Talia was the latest of Ra's al Ghul's four-hundred and fifty daughters. Talia showed a maturity beyond her years as a young child, once accusing her father of having a "messiah complex." While she meant it as an affront, Ra's took it as a compliment and simple truth.
While Ra's al Ghul was training Bruce Wayne, Talia was conducting business for her father in in Switzerland. Ra's considered introducing her to Wayne when his training was complete and marrying them off, but Wayne betrayed him.
Talia did not appear at all in the film itself, but was referenced in the novelization by Dennis O'Neil. She has appeared in the second sequel The Dark Knight Rises in the guise of Wayne Enterprise executive Miranda Tate.
