Alvin and the Chipmunks Wiki

Thalia Al Ghul (voiced by Andrea Bowen) is the recurring villain in the 2008 superhero television series Batman: The Brave and the Bold and also one of the secondary villains in Alvin and the Chipmunks: House of the Bloodthirsty Assassin. She is the estrange daughter of Batman's deadly enemy Ra's Al Ghul (Peter Woodward). Most importantly, she is also the estrange mother of Damian Wayne, through an unexplained relationship with Batman. Like her estrange father, Ra's Al Ghul, she was completely unaware that Batman's real name is Bruce Wayne. In Batman: The Brave and the Bold, her occupation is a mass murderer instead of a biker.


Little is known of Thalia Al Ghul before her first encountered with Donald Walls, but it is known that she was leader of a group of female bikers, and two of her members were the Cheetah/Priscilla Rich (Morena Baccarin) and Poison Ivy/Pamela Isley (Jennifer Hale).

In the summer of 2000, Thalia, Poison Ivy, and the Cheetah stop at small convenience store at Monterrey Park, California. Both Poison Ivy and Thalia held Jeanette and Eleanor hostage while the Cheetah/Priscilla was making trouble for Brittany Miller (Christina Applegate). When she Jeanette Miller's thrown wallet, she wants Brittany to ask her politely for the wallet back and address her as Priscilla, so the Cheetah/Priscilla does. Both Thalia and Poison Ivy let both Jeanette (Anna Faris) and Eleanor (Kaley Cuoco) go. While they and Brittany get ready to leave, Thalia was outside in front of the store drinking a can of root beer as she sees Brittany, Jeanette, and Eleanor inside the car. When Jeanette starts the car, Thalia begins smashing the windshield of a car that Jeanette was driving. However, due to her clumsiness, Jeanette runs over their motorcycles as revenge for troubling her, Brittany, and Eleanor, causing Thalia to fume and shout in anger while Brittany and Eleanor praised Jeanette as they drive away.

The three female bikers stops at Riverside suburbs. Thalia goes to the haunted house across from Ashley Grey's house and discovers Poison Ivy/Pamela Isley dead. When she sees Donald Walls (posing as Theodore Seville) jumping down, she grabs a meat cleaver, hoping to defend herself from the bloodthirsty killer. Theodore/Donald continues his scope out of the haunted house, only to have Thalia appear and starts attacking him with a meat cleaver. Theodore/Donald counter-attacks by hitting Thalia with a tennis racket. While Theodore/Donald is trying to kill Ashley Grey (Bella Thorne), she runs into the haunted house. She is suddenly met by Thalia, who survived the earlier fight with Theodore/Donald. Enraged, Theodore/Donald turns his attention to Thalia by using a meat cleaver to chops off her left hand. Ashley Grey continues running in fear as Thalia screams in horror after Theodore/Donald chops off her left hand and hacked her to death with a meat cleaver. Thalia's one-handed corpse, however, was later found and eventually taken away by the paramedics.
