I'll explain. The ultimate weapon, used in Kalos' great war, separated the Pokémon timeline. One with, and one without, meteorites that cause Pokémon to mega evolve. Since Mewtwo was created by Giovanni, he could've manipulated the meteorite to a Mega Mewtwo. Also it wasn't called Mega Mewtwo, it was called Mewtwo Awakened or something like that. I could go on about how Mewtwo's life story and emotions and thoughts contribute to that, but that's your own work. Additionally, in this universe, there are mega stones, in the other, they're aren't. Maybe Mewtwo had a different upbringing in these parellel universe, causing it to take upon a new voice. Btw Ash himself is voiced by a women, just saying...
