Katrina (Japanese: カツコ Katsuko) is a character of the day in the episode Lights, Camera, Quack-tion.
While Ash was looking for a place to train for the Pokémon League, he met Katrina, who challenged him to a battle. However, before it could even begin, Team Rocket tried to steal Pikachu and Katrina's Raichu. After quickly defeating them, Cleavon Schpielbunk appeared and offered both Pokémon a role in his movie, Pokémon in Love.
After auditioning, both Pikachu and Raichu landed roles in the movie, as well as working behind the scenes by helping to create a thunderstorm for the movie.
After filming was completed, both Katrina and Ash expressed excitement at entering the Indigo Plateau Conference.
This listing is of Katrina's known Pokémon:
| Raichu is the only known Pokémon Katrina has. It appeared when Ash was looking for somewhere to train for the Indigo Conference. He found Katrina, and they decided to battle. Ash sent his Pikachu out to battle, but before they could start Team Rocket appeared to try to capture Pikachu. However, they caught Raichu instead. Raichu used Thunderbolt and Mega Kick to get out and knock Team Rocket over. It then appeared on stage for Cleavon Schpielbunk's film, where they had to show off their dancing skills.
Later it was seen in the end of the movie with a battle between two sides. Raichu and Pikachu were in the middle using their Electric attacks to create a thunderstorm. However, Team Rocket appeared and captured all the Pokémon except Misty's Psyduck, which freed them using Confusion.
Raichu's known moves are Thunderbolt, Mega Kick and Thunder*.
