Guys... it just occurred to me.
Among the potential Capcom names that have circled around within the dlc speculation cycle (Dante, Phoenix Wright, Morrigan, Jill, Leon, etc.), what if... they were to go with X, as in Mega Man X (thus him simply being X in the roster). Sure, at first many might think "but he'd be Mega Man's echo", however X, despite having similar gameplay in his games to that of Mega Man, X has more mobility. Aside from having more mobility, unlike Mega Man, X can charge the weapons acquired from Mavericks (thanks to glove enhancements). His Up B would be completely different from Mega Man's since he doesn't have a pet sidekick like Rush. He would depend on one of the many Maverick weapons he's acquired throughout the games (and boy there's a LOT to choose from). Perhaps the charging of his X Buster would be similar to MegaMan's (Forward Smash), but considering X being a more advanced robot (a reploid), I believe it'd be best to assign his X Buster to Neutral B (so he may charge while running). I'd say let's add his name to the pool of Capcom characters that could make it through Ultimate's DLC.
