One question I ask myself since I am a kid:
Is Mega Man left or right handed?
(I am confused each time he turns left or right)
UPDATE: I am adding a bounty for whoever finds me some official press release documents or interviews showing that the character designers of Mega Man wanted him to be left handed, right handed, or .. both at the same time.
Well, after looking at official box art, Megaman uses either hand for his arm cannon. For example, here’s some Japanese promo art from Megaman 3 depicting the cannon on his left arm.
While here’s some Japanese promo art from Megaman 2 depicting the cannon on his right arm instead.
If you check more of the images and box art, there’s no real rhyme or reason as to which hand the arm cannon appears on. So, since he uses either hand just as often in the images and in the games, the only conclusion I can draw from this is that he is indeed ambidextrous.
