Atlas is a character in the BioShock video game series created by Ken Levine, published by 2K Games. He first appears in the first title of the series, where he sets himself up as a benefactor of Jack, the game's player character, upon his arrival in the underwater city of Rapture. During a pivotal scene later in the game's narrative, Atlas discloses that he is actually the crime lord Frank Fontaine in disguise, the main antagonist of the game, and that he had been manipulating Jack to act against the city's founder Andrew Ryan. It is also revealed that he is responsible for orchestrating Jack's mental conditioning during his infancy and later a chain of events that led to his subsequent arrival in Rapture. Atlas/Fontaine also appears in the sequel BioShock 2 through audio diaries, and more prominently in BioShock Infinite: Burial at Sea, a prequel which sets up the events of BioShock.
