The anime follows the quest of one of the main characters, Ash Ketchum, as he and his friends travel around the fictitious world of Pokémon along with their Pokémon partners. Misty is a stubborn tomboy who trains Water Pokémon and has three siblings, Daisy, Lily and Violet, she left the Gym to her three older sisters prior to traveling with Ash in the anime, although she still retained the title of Gym Leader despite this. She first comes across Ash when she accidentally fishes him and his Pikachu out of a river while fishing for water Pokémon. Soon after this incident, Ash "borrows" her bike in an attempt to flee from a flock of wild Spearow. The bike is later charred by an attack from Pikachu. Misty tells Ash she will not leave him alone until he replaces the bike and commits to follow him on his journey, and the two soon become best friends. After retrieving her repaired bike at the end of the Johto League Silver Conference, she returns to the Cerulean Gym and resumes her duties as the Gym Leader.
