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