Misty is a character whose first appearance was in the very first episode of the anime series, Pokémon - I Choose You!.
In the episode, she first meets Ash after fishing him out of the water when he was trying to get away from a flock of Spearow. Ash then takes Misty's bike from her in order to escape the Spearow, which is then wrecked by Pikachu's Thunder Shock. Misty then tracks down Ash and follows him around on his adventures until he can pay her back, although she eventually forgets about the bike and becomes one of Ash's closest friends in the process. However, at the end of their journey through the Johto Region, Misty's bike has been fully repaired, and she departs to return home to Cerulean City to resume as a Gym Leader.
She's currently the Cerulean City Gym Leader, after her elder sisters.
Misty has a slight inferiority complex, mostly due to her three older sisters Daisy (oldest), Violet (second-from-oldest) and Lily (third-from-oldest), who formed the group, "The Three Sensational Sisters" (their synchronized swimming group), and refer to Misty as the "runt" or "weaker one". This complex diminishes over time as Misty grows closer to them. Until Misty resumed her duties as the Cerulean City Gym Leader, her sisters were the ones who directly ran the gym, although when Ash came along to get his Cascade Badge, it was Misty who battled him for it, explicitly referring to herself as being one of the Gym Leaders during this instance.
Misty specializes mainly in Water-type Pokémon, which are her favorite type, but she's had other types, and she also deeply admires Lorelei, an Ice-type Pokémon trainer. Misty aims to become a world-class trainer, and her well-trained Pokémon reflects her aspirations of becoming so. Her least favorite type of Pokémon is Bug-type Pokémon, as she has a deep-rooted fear of them (except for the kinds she sees as "cute" or "pretty"). However, Misty's fear lessens over the course of the series — but not to the point where she's totally gotten over it, as shown in A Real Cleffa Hanger.
As the series continues, she gradually shows herself to be kind and sensible. Sometimes she would restrain Brock from girls, often pulling him away by the ear and reprimanding him for his behavior. This trait continued with the friends who join Ash on his journeys after she parted ways with him, following their journey through the Johto Region.

Misty doesn't appear physically in the School Daze episode "Weekend at Gammy's", but she does appear in a few flashbacks.
Christmas Chronicles 2: Anime Extravaganza Edit
Misty returns in this series. However, does not return to Franklin with Ash and Brock. Instead, she stays behind to assist Professor Oak in his lab and protect the Everfruit found in "Weekend at Gammy's", which was eventually stolen. She also visited the gang on Christmas Day, appeared in a few flashbacks & cameos, and picked them up from Franklin.
School Daze 4: Road to the Omniverse Edit
Misty is teleported to an alternate timeline based on the original Pokemon video games. Eon has erased her memory of meeting or traveling with Ash. However, she got her memory back After Ash destroyed her bike during a Pokemon battle. After rescuing Brock, she helps Ash and the gang defeat Eon before parting ways.
Misty has short, orange hair tied into a side ponytail. She has green eyes and fair skin. She wears red suspenders, a yellow sleeveless tank top that shows her midriff, blue denim shorts that stop at her thighs, and red sneakers with yellow lining and white laces. Her whole midriff is showing, but her belly button is not usually drawn on.
She later maintains her original outfit in her return in Pokémon the Series: Sun & Moon. Beneath her outfit is her strapless two-piece swimsuit which was worn by her counterpart in both games, Pokémon Red and Blue. In SM043, Misty has a Key Stone hidden at the back of her ponytail.
In one episode in Pokémon Chronicles, her primary top is replaced with a yellow sleeveless hoodie shirt but maintains her denim shorts and sneakers from her primary outfit and the color of her denim shorts were purple.
Her new outfit in the Advanced Generation series when she meets up with Ash and Brock in Hoenn, consists of a yellow sleeveless vest with a dark blue button, a dark blue collar, red swimsuit, yellow shorts and orange shoes.
- Despite Misty being a Water-type trainer, she has had some exceptions in the anime — Togepi which is a Normal turned Fairy type, Togetic which evolved from Togepi is a Normal turned Fairy/Flying type, and Azurill which is a Normal/Fairy type.
- Misty is the first victim of the recurring gag in the anime where Ash's Pikachu destroys every main female character's bike. This gag was also transferred to May and Dawn. However, this gag did not affect Iris, Bonnie or Serena, because they did not have bikes.
- Iris and Bonnie were shocked directly by Pikachu, while Serena wasn't shocked at all.
- In the anime, although Misty possesses a fear of most Bug-types, she does make an exception for those she likes (such as Beautifly, Ash's Butterfree, Ash's Heracross and Ledyba), or ones that don't look like bugs (such as Pineco, which looks like a pinecone).
- She also has a fear of Gyarados after crawling into its mouth as a baby (despite it being part Water-type). She overcame this fear and she had a Gyarados of her own that knows the Fire-type move Flamethrower.
- Misty was the one who originated the gag of pulling Brock away by the ear every time he flirted with a pretty woman. This gag transferred to Max in Hoenn, and then Brock's Croagunk in Sinnoh (though Croagunk used Poison Jab instead of pulling Brock's ear, making it easier to drag him away while he was stunned by the poison).
- Misty originally called Ash's Caterpie "ugly" and "disgusting"; Ash later attempted to leave Misty, only to have her secretly following him. Once it evolved to Butterfree, she took a liking to it (thus showing that she didn't dislike all Bug-type Pokémon — just ones that did not fit her view of pretty looks).
- Misty has three things she has a strong dislike for. They are carrots, peppers, and bugs, as she put it in episode 3 of the first series.
- A recurring gag the started in the Orange Islands League is when someone in the show indicated that Ash and Misty were attracted to each other — something both of them denied. In the second Pokémon movie, Misty got jealous after Melody kisses Ash, implying that she truly does have a crush on Ash; although she initially denies it, she changes her mind later and implicitly admits it to be true towards the end of the film. In fact, Misty's Song strongly implies this even more. Previously, in the Orange Island League, Rudy, one gym leader who was attracted to Misty, noticed her feelings for Ash and tried hinting at it to Ash, who was oblivious. In a later episode in the Johto League, Misty even told Ash that one day they would be married, surprising Ash (although it's debatable whether or not she meant that they would end up marrying each other).
- Misty is the only female main character to appear in more than one generation as she appeared in Generation I and II as a main character, while May, Dawn, Iris, Bonnie, and Serena have appeared in only one generation as a main character yet.
- Also, she is the only female traveling companion to appear in more than two series, as she appears in the Original series, Advanced Generation series, and Sun & Moon series.
- Misty adopts a different personality when talking about/interacting with water Pokémon, as noted by Ash in the episode Tentacool & Tentacruel.
- Misty did not actually become Gym Leader in Cerulean Blues, as the Japanese version of that episode had Inspector Joy specifically stating that Misty proved herself well enough to continue running Cerulean Gym. In addition, Misty has also explicitly referred to herself in both versions as the Cerulean Gym Leader in "The Waterflowers of Cerulean City", "Totodile Duel", and "Entei and the Unknown Tower", taking place well before Cerulean Blues.
- Not counting her cameos in flashbacks and photos, Misty currently holds the record for being the traveling companion with the longest "non-appearance gap" in the anime with 573 episodes between "A Real Cleffa-Hanger" and her reappearance in "Alola at Kantō! Takeshi and Kasumi!!"
