Mega Man appears as an unlockable character with the same moves from the previous game.
Mega Man appears on a poster in the Days of Future Past stage along with other cast that were in Marvel vs. Capcom 2, with all but Mega Man with the label of either "Apprehended" or "Slain", which is also homage to the Marvel Comics' Uncanny X-Men storyline Days of Future Past.
His other appearance in the game is that of a card in the "Heroes and Heralds" mode, as an "S Rank" card who's primary ability is halving the time used to charge attacks for characters with his secondary ability increasing the chance to gain rare cards of characters belonging to Capcom.
