While on Mandarin Island, Ash learns that Prima, one of Orange Island’s best trainers, is there as well. When they meet, Prima won’t battle. Angered, Ash challenges a passer-by and uses Charizard who, as usual, doesn’t listen. Prima uses Slowbro and brings down Charizard. Finally, Prima agrees to battle Ash, and after he loses she gives him some advice: if he listens to his heart and the heart of his Pokémon, he will be a great Pokémon Master.
