Robot Master No. 1: Doc Robot
Okay, ignore his derpy art for a second and trust me when I say that Doc Robot is the sneakiest boss in any Mega Man game. He is also my favorite aspect of Mega Man 3. Whenever you battle him (or one of his clones, since it is never said if he is rebuilt or not) you never know what you’re gonna face. Doc Robot steals the “souls” of fallen bosses from Mega Man 2 and uses their powers. The big difference? He’s much bigger and tougher than the originals, and you face him without the particular weaknesses that bested them in the past. This made Doc Robot a fantastic boss, and one I’m proud to have as Number 1!
