Last week, what looked like a new form of Mewtwo was announced for Pokémon X & Y by the Japanese TV show Pokémon Smash. However, it wasn't exactly clear if it was in fact Mewtwo or a completely different 'mon altogether and a massive debate ensued.
Thankfully the latest edition of CoroCoro has emerged in Japan and has confirmed it is a new form of Mewtwo so we can all now rest easy. The pull-out movie poster within the magazine explains that Mewtwo has awakened and has taken on this new shape.
A bit more information was also revealed for the Wii U eShop title Pokémon Rumble U - known as Pokémon Scramble U in Japan. Apparently there will be special abilities - some of which can be set manually - and shiny Pokémon are making a return. The game will also use a password system to obtain some 'mon.
