Break Man

Break Man is the nickname Proto Man is called in Mega Man 3. He is not a character, but it seems that initially Proto Man was prepared to have a special transformation called Break Man in Mega Man 3 that was removed before the game release; he instead appears without making a transformation. In this transformation, Proto Man's helmet covers all his head, taking a form near the same of the Sniper Joe's helmets (even the single eye). Its unknown what this "transformation" would change in Proto Man, but it probably would increase his defense or power.

Proto Man will only appear as Break Man when all four Doc Robot stages are finished. After his defeat, Mega Man will return to Dr. Light's Lab, where Dr. Light says that Wiley (Dr. Wily) stole Gamma.
