4. Proto Man

Put Him In: Marvel vs. Capcom 3
There was a vocal group of fans who decried it blasphemous to not include the blue bomber, Mega Man, in MVC3. Consider us the Proto Man fans in the back of the room and we're protesting to get him in instead. Robots aren't supposed to have the swag humans thirst for. Proto Man, however, breaks that rule. The shield, the blaster, the red and gray get-up, plus his iconic whistle tune made us love the guy. If Proto Man could make Mega Man his bitch in the middle of a stage, imagine how much he could humble Zero in MVC3. Oh, and his shades are sweeter than Wesker's.
