Pokémon: Giratina and the Sky Warrior
The film begins with Shaymin and Dialga. Giratina then senses Dialga's presence in the Reverse or Distortion World and flies to the Real World to catch him. Just as Giratina's portal opens, Dialga drinks. Then, Dialga is dragged into the Reverse World by Giratina. Also propelled into the Reverse World is Shaymin. Zero sees Dialga and Giratina's combat from his ship. Shaymin absorbs a black gas and uses "Seed Flare" to escape the Reverse World by tearing a hole in it. Dialga launches a laser towards Giratina, trapping her within a time loop and the Reverse World. Shaymin falls into a river while Dialga flees.
