The most secret and most powerful of Dr. Wily's projects. So secret and so complex in fact that he's not even close to completion by the time he's released from stasis. Even though this prototype robot has no weapons, this mysterious newcomer quickly proves himself far more than a match for Megaman, easily batting aside every single one of his attacks. The mysterious yet powerful robot is none other than Zero but in an unfinished, prototype state and is easily prone to malfunctioning.
