Mewtwo may return in Smash Bros., possibly with his new X and Y form.
During last week’s Pokémon X and Pokémon Y Developer Roundtable at E3 there was a Q & A session with Tsunekazu Ishihara, President and CEO of the Pokémon Company, and Junichi Masuda, Director at Game Freak. I was fortunate enough to ask the men the following question:
“Can you go into more detail on how Mewtwo changes forms, and would you like this new form to appear in the new Smash Bros.?”
Upon asking this question the audience burst into laughter. Both Tsunekazu Ishihara and Junichi Masuda also had a surprised look on their face and appeared to not know how to safely answer the question. Sakurai was also in the audience and looked as if he were thinking, “Oh man, not this again!” after the question was asked.
After a brief moment of silence, Ishihara and Masuda answered by saying they don’t have anything to announce about the new Pokémon (Mewtwo’s new form) today, and that they can’t speak on its appearance in other games. Sakurai then shouted out, from the audience, “We are thinking about it.”
