The 2008 video game "" features a character known as the "Doppelgänger." She is a clone of protagonist Lara Croft, created by antagonist Jacqueline Natla to break into Croft's mansion and unlock a safe containing an important artifact. As the safe is protected by a retinal scanner, it requires someone with the same DNA as Croft to unlock it. The Doppelgänger ends up killing Croft's friend and researcher Alister Fletcher, and burning down the mansion. She would then go on to become a major antagonist and boss in the game. In a 2009 DLC expansion pack called "Lara's Shadow," Croft takes control of the Doppelgänger, and she becomes the player character for this level.
