Ash Ketchum dreams of being the world's greatest Pokémon trainer, and ends up partnered with a strangely-overpowered Pikachu by Professor Oak. Meeting new friends and rivals along the way, Ash and Pikachu soon find themselves on the most-wanted list of the notorious Pokémon-kidnapping crime gang Team Rocket, who are after Ash's Pikachu. On top of this, Ash and his friends are invited to a Pokémon tournament by a mysterious lab-born Pokémon named Mewtwo, which leads them to investigate the mysteries behind both Professor Oak and Team Rocket's past.
