Talia al Ghul
From LEGO Batman Wiki
Talia al Ghul is Ra's al Ghul's daughter. Talia carries a sword and is very skilled at using it. She is in love with Batman but her loyalty for her father keeps her and Batman from being together. Though typically a rival of Batman, Talia's love for the Caped Crusader can sometimes lead her to help him when he really needs it.
She can be bought for 60,000 studs. She is not in any levels or Villain Hunt. She wears a white shirt and black pants. She is also very acrobatic and can use acrobat points and walk on tightropes.
