During each season of the main series, a Pokémon Feature Film (劇場版ポケットモンスター Gekijōban Poketto Monsutā?, Pocket Monsters Movie) starring the main characters from the TV series has been released. As of 2013, there have been 16 movies and one feature length TV broadcast (released outside Japan as a direct-to-video movie titled "Mewtwo Returns"). The plot of every movie has involved an encounter with a Legendary Pokémon, although some may not conform to a strict definition of the word. The movies are also used to promote new Pokémon that appear in new versions of the game and series.
