The first Pokémon feature-length special was aired on Japanese
TV on December 30th, 2000, under the title Pocket Monsters: Mewtwo Lives.
It went direct-to-video in the US and hit shelves on December 5th, 2001 under
the title Pokémon: Mewtwo Returns.
This special follows on from Pokémon: The First Movie (Mewtwo Strikes
Back), the first theatrical Pokémon release.
Deep in a remote area of the Johto Region is a place with crystal clear waters,
forbidding mountains and a secret. Mewtwo and his fellow super-clone Pokémon
have finally found a home where they can live and thrive, far from the prying
eyes and harsh judgements of the humans.
In Pokémon: The First Movie, Mewtwo removed all traces of his battle
with Mew, of the clones, and even of his very existence! Everyone's memory
was
erased except for Giovanni's, the evil force behind Mewtwo's creation.
Now the devious Team Rocket leader has discovered Mewtwo's idyllic hideaway. And
as luck would have it, so have Ash, Pikachu, and their friends.
Soon Giovanni confronts Mewtwo with an agonizing challenge: submit to his human
authority or stand by as the super-clones are sacrificed. An all-out battle
seems certain, but the startling effects of their unique environment suddenly
come into play... leaving the fate of Mewtwo in Ash's hands!
