This year’s Pokémon Movie has debuted in Japan today. At the end of Pokémon The Movie: Everyone’s Story, there was a teaser for next year’s Pokémon Movie. Pokémon The Movie: Mewtwo Strikes Back Evolution will premiere next year. There have been reports in Japan that the original voice actor for Mewtwo, Masachika Ichimura, did the voiceover for the post-credit teaser with the lines “Who am I? Where am I?”
The Logo for the movie is the same for the original Mewtwo Strikes Back but with the inclusion of the words “Evolution” in English. No more information has been shared at this time and the teaser has yet to be published online.
