Version 7
A new and mysterious female D.A. emerges Talia Head and sparks the interest of Bruce Wayne and she is secretly Talia al Ghul (Despite not appearing in Batman Begins, where Ra's al Ghul is the main villain, she is mentioned in the novelization when Ra's writes to his daughter in Switzerland and al Ghul's character biography in the DVD special features.) She is a complex character, not quite heroine nor villainess but more of an anti-hero. Talia has brought a team of the remaining League of Shadows Warriors to Gotham City to hunt down the Batman and force him to join them or pay for her father’s death. The League is fully aware that the city has been under siege from the Black Mask and his False Face Society for years.
The Joker was used by the Black Mask who wanted to move in on the mob families in Gotham, to tear apart the structure built up by Sal Maroni and at the same time destroy the influence of Batman. The Black Mask is an older man, very rich, and a rogue member of the league of shadows. After leaving the League he formed the False Face Society who recruited the Joker. Black Mask's most important weapons are fear and intimidation. He is known for his brutal and sadistic torture techniques, especially on the face. He sees the Joker’s purpose was served as he drove the Batman from hero to vigilante in the general public eye, and needs to dispose of the Joker before his identity is revealed. The Black Mask is secretly also a wealthy business man and has the pull to push around Bruce Wayne and also fabricate documents and information. His Intel is unparalleled, he nearly completes a hostile takeover of Wayne Enterprises, and he is a master criminal strategist with vast amount of resources. He was the crime lord of Gotham city for many years as an undercover businessman and was the original target of Ras al Ghul. Black Mask also uses his connections to gather information on his enemies, and then hits them at their weak points, such as family and friends. (ties to Thomas Wayne, and his death) The Black Mask infiltrates Wayne Enterprises and in an attempt to take over the building kills Lucious Fox. Black Mask commits a series of murders disguised as Batman. This plan is complicated by the escape of Joker. Joker finds and seeks revenge on the Black Mask exposing his true identity and scarring him in the process. The False Face Society and the League of Shadows Hunters led by Talia go to war in the streets of Gotham.
Climax would be Joker now destroying what’s left of the mob and taking over the reins of The False Face Society. He holds the city for ransom by revealing he has a plan to detonate another bomb similar to what destroys Wayne enterprises.
