Pokémon: Giratina and the Sky Warrior
Shaymin first appears in the film as Dialga. Giratina then senses Dialga's presence in the Reverse or Distortion World and flies up to the Real World to capture him. Dialga takes a drink as Giratina's portal opens. After that, Giratina drags Dialga into the Reverse World. Shaymin, too, is thrown into the Reverse World. Zero observes the fight between Dialga and Giratina from his ship. Shaymin absorbs a dark gas and uses "Seed Flare," tearing a hole in the Reverse World and escaping. Dialga fires a laser at Giratina, enveloping her in a time loop and trapping her in the Reverse World. Shaymin falls into a river while Dialga flees.
