I'm not sure about the new form really. I'm not sure how it will all turn out in terms of how it makes it more powerful, but the storyline behind it in the movie will be amazing for sure. So you watch anime? I've watched the Mewtwo movie a number of times its one of my favorite pokemon movies, if not my most favorite. If you wanna discuss anime then you can do so here:Pokemon Anime
Also if you want to discuss the new mewtwo form or anything else relating to X/Y, this would be the place:Pokemon X & Pokemon Y
If you decide to get more into Spinoffs, then that would be found here: Spinoff Games
