It was outed by Entertainment Weekly during Comic-Con 2011 that Talia al Ghul will be making an appearance in Batman: Arkham City. The daughter of the villain Ra's al Ghul will be voiced by Stana Katic (Castle). If you're not familiar with Talia from Batman lore, she played a love interest of Batman's and became the eventual mother of the caped crusader's son, Damian. Here's a picture of Talia's character design in Batman: Arkham City.
I must admit that after seeing Harley Quinn and Catwoman's designs, I was a bit disappointed with Talia's. What do you think? Also, don't forget to check out the news that Solomon Grundy will also be making an appearance in Arkham City. It seems like just about everyone can make it into this game. Who do you want to see next?
Batman: Arkham City will be out for the PlayStation 3, Xbox 360, and PC on October 18.
