A stubborn tomboy, Misty is the youngest of four sisters who live in the Cerulean Gym. Fed up with her more glamorous older sisters, Misty left the Gym with the goal of becoming the world's greatest Water Pokémon Trainer. She met Ash when she "caught" him with her fishing line in a river between Pallet Town and Viridian City. She traveled around with Ash, Brock, and Tracey through the Kanto region, Orange Islands, and Johto region. Her purpose was ostensibly to get Ash to replace her bicycle, which he had accidentally destroyed when they first met. However, Misty often seemed to have forgotten about the bicycle, indicating that her real reason for following along was that she simply wanted to remain with her friends.
