The giant poster in the dystopian stage "Days of Future Past" is an homage to the cover of The Uncanny X-Men #141 and features a band of characters who appeared in MvC2 but were left out from MvC3. Cyclops, Colossus and Iceman retain their respective places and statuses since they were both in MvC2 roster and the comic cover. Mega Man is shown to be still at large, possibly as a response to the fans craving for him to be playable in the game.
