What subtitle does Pokémon: The First Movie use in its full English title?

Pokémon: The First Movie uses the subtitle “Mewtwo Strikes Back” in its full English title.

The complete title is Pokémon: The First Movie – Mewtwo Strikes Back. The Japanese animated film was directed by Kunihiko Yuyama and first released in Japan on July 18, 1998. Its story centers on Mewtwo, a genetically engineered Pokémon who challenges the humans involved in his creation.

The film was the first theatrical Pokémon anime movie. In English-speaking markets, Warner Bros. released the English-language adaptation in 1999. The movie was accompanied by the short film Pikachu’s Vacation in theatrical screenings.

The subtitle is sometimes confused with Mewtwo Strikes Back—Evolution, a 2019 computer-animated remake. That later film retells the first movie’s story but is a separate release and not the title of the original 1998 film.
