There's a new, mysterious Pokémon that looks suspiciously like Mewtwo. We don't know much about it, though judging by appearance alone, it's hard to fault anyone for thinking the Pokémon is a new Mewtwo form. And if that's the case, I hope Mewtwo transforms into the new Pokémon like in this short video by alypkm. Amazing.
For some context: the video uses a magical girl transformation sequence, like that of Sailor Moon:
Unfortunately we'll probably have to settle for something a lot less magical in the anime/games.
