Story
Doppler was a Reploid and researcher. He watched the war between the Maverick Hunters and Sigma, and hoped he could do something to stop this war. He created the utopian Doppler City, where all reploids who were tired of the Maverick Wars gathered, with Dr. Doppler as their ruler. He studied the Sigma Virus, and successfully developed a anti-virus vaccine that he soon distributed among the denizens of his city. However, the anti-virus was a fake, and the reploids start to go maverick in the city. Doppler gathers an army of Mavericks and starts a full-scale attack against the Maverick Hunters base. X and Zero rush to the base to intercept the attack. X enters the base and finds Mac, who was a Maverick Hunter. He traps X and capture him, telling that he now worked for Doppler. Zero destroys Mac and rescue X, so the both of the goes to Doppler City to find Dr. Doppler and stop him. Doppler hires two police reploids, Bit and Byte, and also revives Vile to hold off X and Zero. X defeats Doppler's Mavericks and proceeds to his lab along with Zero. After defeating the fused Bit and Byte, as well as Vile, X finds Doppler and fights him. As x defeats the doc, he recover his consciousness, revealing that he was being used by Sigma all along, having built a new and more powerful body for him. X then goes after Sigma and defeats him. When the viral form of Sigma tries to possess X, Doppler intervene by trapping Sigma within his own body, which contained the true anti-virus that he developed. X manages to escape while the lab explodes, as Sigma's code starts to vanish due to the anti-virus effects.
