Talia al Ghul

Talia al Ghul (b. 1983) is the daughter of Ra's al Ghul and a member of the League of Assassins. When Bruce Wayne went to Nepal in 1991 and trained underneath her father, Ra's decided that he would be his successor as leader to the League and wanted to betroth him to Talia. At the time, Talia was a child and nowhere near presenting, which led to Bruce leaving the League out of horror and disgust.
Bruce's departure did not stop Talia from wanting to fulfill the role that Ra's had wanted to give her. In May of 2003, she came to Gotham to talk with Bruce and try to convince him to become her father's successor and all that entailed, proposing that she and his husband, Tony Stark, would be co-spouses to him. When her attempt failed, Talia left, but not without warning Bruce that her family would get what they wanted regardless in the end.
