Kip. 18: Destination: Coronation!

18

In order to boost his ranking in the World Coronation Series, Ash and Pikachu, along with Goh and Raboot, head out to the Vermillion Gym to face their old opponent Lt. Surge. However, with Lt. Surge away, the gym is now being run by Visquez. Their battle is a two-on-two match, with Pikachu starting out for Ash and Raichu for Visquez. During the battle, Ash recalls Pikachu and sends out Gengar, who defeats Raichu. Visquez sends out Electrode, who defeats Gengar, so it is all up to Pikachu ... and Raboot is watching closely!
