"Mewtwo is a Pokémon that was created by genetic manipulation. However, even though the scientific power of humans created this Pokémon's body, they failed to endow Mewtwo with a compassionate heart."
Mewtwo is one of the most popular Pokemon ever, not the least of which was because of his antagonist role in Pokemon: The First Movie. But beyond that, Mewtwo is just an epic Pokemon. It was created by Team Rocket scientists to become the worlds most Pokemon, "and we succeeded..." and it was so intelligent and powerful that not only could it speak English, but defeat numerous Pokemon easily, and even control humans. To this day, Mewtwo is still revered and was even a big focus in the first Pokemon GO trailer.
Mewtwo's Basic Attacks are Confusion and Psycho Cut, while its Special Attacks are Psychic, Shadow Ball, Hyper Beam and Focus Blast
