Break Man

Break Man is a nickname of Proto Man used in the first part of Mega Man 3. It seems that initially Proto Man was prepared to have a animation, which he transformed into Break Man, in Mega Man 3 that was removed before the game release; he instead appears without making the transformation. In this form, 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 probably it was just an disguise.

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.

In the ending, Dr. Light recognize his whistle, reveling that Break Man is in fact Proto Man, brother of Mega Man.
