Misty is a 10-year-old Pokémon trainer who journeys with him throughout the first five seasons. She is revealed as one of the four gym leaders for Cerulean City in episode seven. Her dream is to be the world's greatest "Water Pokémon Master," but her means of accomplishing this are never really made clear. She has made several friends and rivals over the course of her journeys and claims she is a better Pokémon trainer than Ash. Her sisters never treated her well, and that story came up from time to time when she was traveling with Ash.
