Sigma's face features a pair of scar-like marks run down both eyes, resembling a snake bite. While these forms are drastically diverse, his humanoid design remains fairly consistent.

Although he has been destroyed countless times, Sigma's programming always survives and builds himself a new form. Sigma appears as a tall, bald humanoid in most of his forms.

His primary enemies are X, Zero, and more recently, Axl. It is implied that he grows more insidious and vengeful with each transformation, with each successive plan becoming more and more desperate and aggressive. Sigma instigates many of the destructive Maverick Wars, with the Maverick Hunters existing to crush Sigma and his minions.Īlthough he has been destroyed countless times, Sigma's programming always survives and builds himself a new form, ready to menace the world once again. Under Sigma's command, the Mavericks grow into a legion dedicated to the extermination of the human race. He defects to the Mavericks and assumes the role of their leader. Although he was once honorable, Sigma unexpectedly goes Maverick in the beginning of Mega Man X and rebels against humankind. Sigma was considered the finest of the Reploids and was the first leader of the Maverick Hunters peace-keeping Reploids who defend humans against their renegade counterparts known as Mavericks. He serves as the final boss in all games in the series except Mega Man X: Command Mission (where he makes no appearances) and Mega Man X8 (appearing as the final boss if the game is played on easy, and as the penultimate boss if the game is set to normal or hard difficulty, since Lumine is fought on normal or hard). Sigma ( シグマ, Shiguma ?) is a character and main antagonist of the Mega Man X series.
