If you haven’t heard yet, Mewtwo is coming to Super Smash Bros Wii U and 3DS as a DLC. According to director Masahiro Sakurai, that DLCs is “pretty much done!”
Back in October, Nintendo announced that Mewtwo would be a playable character but come into the roster after the release as a downloadable character. While no date was given at the time, director Sakurai said at an event in Japan that the DLC is “pretty much done,” and it is coming “pretty soon.”
Mewtwo will be free for owners of both Smash WiiU and 3DS; however, he will be available for a price for owners of only one version of the game. That price has not yet been revealed yet.
