Lucy is the Frontier Brain and law-keeper of the Battle Frontier's Battle Pike. Her costume is made to look like a Seviper, her signature Pokémon. She is the only character in the games to have the Trainer class Pike Queen. Lucy has a remarkable preference for serpentine Pokémon and uses their tails as the perfect offensive strategy. In addition to serpentine Pokémon, Lucy likes Pokémon with squinted eyes, a preference that was responsible for her crush on Brock.
