Pokémon: The First Movie - Mewtwo Strikes Back

Team Rocket uses a fossil from the Legendary Pokémon Mew to produce its first successful clone: Mewtwo. Created by human hands and shaken by the circumstances of its birth, Mewtwo turns on its makers and is soon drawn into Sakaki’s schemes, pushed toward increasingly cruel deeds.

Disgusted by humanity’s deception and the suffering it has endured, Mewtwo withdraws from the world while searching for meaning and a reason to exist. Taking on the guise of an unbeatable Pokémon Trainer, it lures top challengers into a confrontation. With disaster looming, Satoshi, Takeshi, and Kasumi step forward to face Mewtwo and stop its plans before they threaten humanity itself.
