Pokémon the Movie 2000

When Lawrence III's scheme to capture the Legendary Pokémon Lugia upsets the balance of nature, it is up to Ash Ketchum and his friends to save the world. The film follows Ash as he discovers three legendary bird Pokémon - Articuno, Zapdos, and Moltres - with the power to awaken Lugia, which proves dangerous for the legendary Pokémon, Lugia, and Ash himself. As the weather starts to change, Ash and his Pikachu are brought by boat to Fire Island, where they find Moltres' treasure, but they are interrupted by Team Rocket. With the prophecy seemingly coming true, Ash is the actual Chosen One, and Lugia, revived when Melody plays the festival song on her conch, explains telepathically only Ash can restore harmony to the world by retrieving Articuno's Treasure.
