GLaDoS is a bounded and gagged woman[]
According to this fan theory, GLaDos, the video game's antagonist, is actually a human that was bound and gagged for unknown reasons. According to the theory, one of the writers of the game explained that GLaDoS was originally based upon the famous Botticell painting, "The Rise of Venus," and that they had ultimately chosen a delicate mechanical body that would define GLaDoS' feminity and power.
