>>20114825Call me delusional, but if the Fire Emblem reveals told us anything, it's that the roster will be quite big, and that cramming franchises with random and unnecessary reps is the game now.
Mewtwo has been playing an important role in the Pokémon franchise lately, going as far as having two Megas for the launch of X and Y alone. Shit, X's Mega is even completely fit for the role of Mewtwo's Final Smash!
Who knows? Maybe the guy is back and we don't know it yet for it won't be revealed pre-launch, à la Brawl's Ness and Cpt. Falcon.
