Pokémon 4Ever

In the past, a Celebi is rescued from a Pokémon Hunter by a young boy named Sammy. Using its time-traveling abilities, Celebi transports itself and Sammy forty years into the future. There, Ash, Misty, and Brock encounter them and learn of Celebi's need to reach a healing lake. However, an evil Team Rocket member known as the Iron Masked Marauder, Viscious, attempts to capture Celebi with his technology. Jessie, James, and Meowth also seek to capture the legendary Pokémon. Ash and his friends must evade Viscious and the other Team Rocket members while guiding Celebi and Sammy back to the forest. The fate of the forest, and their own safety, depends on Celebi's well-being.
