Zero, having suffered a programming flaw from his creation, was uncontrollable, unleashing wanton destruction wherever he went. It is here that Sigma encountered Zero, the last product of Dr. Sigma then left to confront it alone, in order to prevent other Reploids' deaths at the hands of the Maverick. While investigating, Sigma, along with his unit, tracked it down to an abandoned laboratory. One day, the Maverick Hunters received reports of an overwhelmingly powerful "Red Maverick" that has destroyed an entire squadron of Hunters (the Gamma unit). He was placed in charge of the 17th Elite Unit of the Maverick Hunters, and led them to victory multiple times. Cain implanted the latest circuitry designs into Sigma, which were theoretically supposed to prevent him from going Maverick. His primary enemies are X, Zero, and more recently, Axl.Īs the former leader of the Maverick Hunters, Sigma was originally the most advanced Reploid of his time. 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. Cain, 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.
