Misty is the tritagonist of the original Pokémon anime series. Although Misty is the leader of the Cerulean Gym in the games, she left the Gym to her three older sisters prior to traveling with Ash in the anime. She was Ash's first female traveling companion.
She first came across Ash when she accidentally fished him and his Pikachu out of a river while fishing for water Pokémon. Soon after this incident, Ash borrowed her bike, attempting to flee from a flock of wild Spearow. The bike was later charred by a Thundershock from Pikachu. Misty told Ash she would not leave him alone until he replaced the bike and committed to follow him on his journey, and the two soon became close friends. After retrieving her bike at the end of the Johto League Silver Conference, she returns to the Cerulean Gym and resumes her duties as the Gym Leader.
As such, she is not ever featured as a character in the later seasons, only appearing in a few episodes and specials. She became a central character in Pokemon Chronicles, a spin-off to the Pokémon anime. She maintains her friendship with Ash and once greeted him when he returned to Pallet following a long stint in Hoenn. In the early episodes, Misty is depicted as having a wicked temper, stubborn temperament, and little patience. As the series progresses, however, she gradually shows herself to be kind and sensible. Although she regularly displays a somewhat romantic streak, Misty constantly reins in Brock when he becomes enamored with cute girls (style of Barbie dolls), often pulling him away by the ear. She has a slight rivalry with Ash, and she is also terrified of most Bug-type Pokemon. Misty aims to be a world-class Water-type Pokemon trainer despite her sisters' ridicule.
In the original series, Misty is shown wearing a yellow crop top and jean shorts held up with red suspenders. She also wore red, yellow and white sneakers.
