When the Genesect begin rampaging in the city, Ash is protected by the sudden appearance of a familiar Pokémon Mewtwo. Despite sympathizing with the plight of the Genesect, Mewtwo attempts to convince them to leave New Tork City and go somewhere else where artificial Pokémon can belong, only to get into a conflict with the Red Genesect that leads the team.
