(since i ranted on about nazo might as well do the same with mewtwo XD)
now, i love mewtwo, i alwayed played leafgreen just to catch him, and when i saw him in X and Y it gave me a whole another reason to buy the game, but then i saw the movie Genesect and the Legend Awakened, were mewtwo returns, but you can clearly hear mewtwo has a new voice, and doesn't remember ash or pikachu, it's odd
did the scientists who created mewtwo make 2? i know they were trying to create a clone of mew, and failed many times (i believe the ditto are mew clones theory btw) but when they successfully made mewtwo, did another form or not, in the first movie, you see mewtwo destroy the lab and kill all the scientists, so what happened?
another interesting question
