Dorian has his own Gym like A.J. and is a fan of Daisy, Violet, and Lily, and (like them) thought that Misty was a runt. Ash and Misty challenged him to a battle, which proved to be quite a challenge. Team Rocket appeared and took some of the Pokémon, then tied Dorian and Misty up. Ash and Brock rescued them, while Psyduck got bitten on the head and showed off his powers, so Dorian gained respect for Misty for having such a powerful Pokémon.
