Pokémon the First Movie: Mewto Strikes Back

In a Team Rocket lab located near Cinnabar Island, a few prestigious Pokémon genetics scientists create from the DNA of Mew, the mythical Pokémon, a new creature whom they called Mewtwo. Mewtwo would be, according to them, the improved version of Mew, the singular Pokémon. Once the "experiment" is finally created, the scientists explain to him why he is more powerful than Mew, Mewtwo feels a kind of uncertainty about what will happen to him. They answer that now the real tests will begin and Mewtwo realizes that they only want to use it as a mere instrument to capture Pokémon. However, despite the scientists creating a powerful Pokémon, they forgot to give Mewtwo a good heart. Filled with hate, Mewtwo destroys his creators and decides to take down the world. But first, it will gather the best Pokémon trainers in the world for an epic battle in which coaches must unite all their power to prevent the destruction of the world. Among the coaches are Ash, Misty and Brock who, along with Pikachu, will face the fearsome Mewtwo.
