Pokémon: Giratina and the Sky Warrior

The legendary renegade Pokémon, Giratina, meets the temporal Pokémon Dialga near a lake and pulls it into its own world-a separate dimension from the normal one. But a small green Pokémon is also caught in the struggle. Though it manages to escape, Dialga seizes the chance to break free too, stopping Giratina from chasing after it. After accidentally disrupting Satoshi and his friends' picnic, the green Pokémon is taken to the Pokémon Center for treatment and identified as Shaymin, the mythical Gratitude Pokémon. Using telepathy, Shaymin insists that Satoshi, Hikari, and Takeshi help it reach a certain destination. Before they can figure out where to go, however, they're hunted by Giratina and a mysterious man named Zero-both desperate to capture Shaymin. Can Satoshi and his friends safely guide Shaymin to its goal while avoiding these dangerous pursuers?
