Dorian is a Water-type Pokémon Trainer who runs the unofficial Coastline Gym near a beach south of Blackthorn City. Dorian puts on synchronized swimming shows with his Pokémon because he's a big fan of The Sensational Sisters - Daisy, Violet, and Lily. Misty in particular was enraged by Dorian's statement that Lily was prettier than she was. Dorian defeats Ash, but Dorian later respects Misty after she shows off her Psyduck's powerful Confusion attack.
