Hearing about the trainer with the strongest Pokémon in the world, the heroes came to Anthony, who showed his Pelipper. Ash challenged Anthony to a battle, by sending Treecko, Taillow and Pikachu. During the battle, the heroes were surprised when Pelipper launched Flamethrower, Thunderbolt and Vine Whip, attacks it normally could not execute. Pikachu managed to collide with Pelipper and nearly defeat it; but with the two Pokémon quite hurt, Anthony and Ash canceled the battle. Team Rocket heard of this and made countermeasures against the mighty Pelipper to capture it. Once they grabbed it, Pelipper had dropped Magby, Bellsprout and Magnemite, which Anthony put in Pelipper's mouth to gain advantage. Team Rocket managed to blackmail Anthony and trap him in a room, while they started challenging trainers (by using Pelipper) and take their Pokémon, as an stake for the battle. Once Max found out Anthony was captured and Pelipper accidentally used Water Gun and got Meowth and the Poké Balls out of its mouth, Team Rocket tried to flee, but were eventually defeated. Anthony realized his mistake and stopped his scam, promising to train Pelipper.
Anthony's Pelipper kept Pokémon in its beak so they could use attacks during Pokémon battles that Pelipper couldn't normally learn.
