Agent 47 is a fictional character and the main bald protagonist in the Hitman video-game series. Created by IO Interactive, the character was developed around David Bateson, who also provided the in-game voice. 47 has appeared in all four installments of the Hitman series, in the novel Hitman: Enemy Within, as well as the film adaptation in which he was dramatized by Timothy Olyphant. A genetically-enhanced bald clone trained to assassinate targets, the agent's name is derived from the last two digits of his assigned barcode which is tattooed on the back of his head, reading 640509-040147.
