Synopsis

May throws a Poké Ball, then is shown in a spotlight running with all her Pokémon before they jump into the air and Ash Ketchum, Ash's Pikachu, Brock, and Max appear. She then twirls around before her Squirtle shoots an Ice Beam that reflects various images of May. In the final image, she winks at the camera before Munchlax breaks the ice with a Focus Punch. Then she and her Pokémon are shown running across a field with mountains in the background.

May stands in another spotlight, this time alone, and colored spotlights move around her. Images of her Beautifly, Skitty, Squirtle, and Bulbasaur flash by. She looks up, apparently determined. Images of her Eevee, Munchlax, and Combusken flash by.

May poses as Combusken uses Fire Spin, Eevee uses Shadow Ball, Munchlax uses Solarbeam, Bulbasaur forms a heart with Vine Whip, and Skitty uses Blizzard. An image of Ash, Pikachu, Brock, and Max pans across the screen, then May is seen eating bowls of ramen as the rest look on in awe.

The final image is May with all her Pokémon. Ash, Pikachu, Brock, Max, Drew, Harley, and Team Rocket are pictured in the background.
