Pokémon: Giratina and the Sky Warrior

Giratina, the Renegade Pokémon, clashes with the Temporal Pokémon Dialga at a lakeside and succeeds in pulling it into an alternate dimension cut off from the ordinary world. In the chaos, a small green Pokémon is swept in as well; it manages to slip back out, and Dialga takes the chance to break free—stopping Giratina from giving chase.

Soon after, the same Pokémon disrupts Satoshi and his friends’ picnic and is brought to a Pokémon Center for treatment, where it’s revealed to be Shaymin, the mythical Gratitude Pokémon. Communicating by telepathy, Shaymin insists that Satoshi, Hikari, and Takeshi escort it to a certain destination—but their journey turns dangerous when both Giratina and a mysterious man named Zero begin hunting for Shaymin, forcing the group to stay one step ahead as they search for the place Shaymin longs to reach.
