Casey (Japanese: ナナコ Nanako) is a nominally recurring Trainer in the Pokémon anime.


Casey first appeared as a novice trainer in The Double Trouble Header, where Ash, Misty and Brock witnessed her capturing a Rattata. Soon after her appearance, Casey battled against Ash. Despite her overconfidence, she was easily defeated by Ash, who used just his Charizard.

After her defeat, Casey was tricked by Team Rocket into believing that Ash had cheated, prompting her to face Ash again, this time battling his Pikachu using her Chikorita. However, the battle was interrupted by Jessie, James, and Meowth, who tried to capture Chikorita and Pikachu. In the end, Ash and Casey united to defeat Team Rocket and became friends.

She appeared in a flashback in The Chikorita Rescue.

She returned in person in The Bug Stops Here, where Ash competed against her in the Bug-Catching Contest. She decided to win at all costs with her Chikorita, which almost caused Ash's defeat. Chikorita evolved to defeat Team Rocket more than once. Before leaving, Ash presented her with the Beedrill he was allowed to keep because he won the competition, because of her admiration for yellow and black striped Pokémon.

Casey catching a Pokémon

Casey returned in Here's Lookin 'at You, Elekid!, where she revealed that her Bayleef had evolved into a Meganium. She also tried to catch a wild Elekid, the pre-evolution of her favorite Pokémon Electabuzz, and with hard work she managed to capture it,

In A Date With Delcatty, she visited Cerulean City in the Kanto region to watch a baseball game with the Starmie team against the Electabuzz team. She met up with Misty and both united to defeat Butch and Cassidy who were trying to steal a Delcatty belonging to Georgio.

Her latest appearance was in Those Darn Electabuzz! where she helped her idol Corey Demario regain his confidence and his Charizard, Don (Jp: ドン Don), regain his abilities to battle and fly.


Casey's team

She and her family are fans of the Electabuzz baseball team, and she loves Pokémon with the team's colors, yellow with black stripes. She started with a Chikorita, which she received from Professor Elm of New Bark Town.

In the original Japanese version, Casey speaks with a Kansai dialect, in which natives to Osaka, Japan speak. Adding to this is Casey's love of the Electabuzz baseball team, an analogue to the real world Osaka baseball team, the Hanshin Tigers. Not only is there a similarity in both Electabuzz and tigers being striped animals, but the Hanshin Tigers are known for having a very loyal fanbase.

Casey has been compared to Ash in his early days of Pokémon training. However, they have different styles of training, and different tastes in Pokémon.

This listing is of Casey's Pokémon as of Those Darn Electabuzz!:

On hand

Casey's Meganium
Chikorita → Bayleef → Meganium
Main article: Casey's Meganium

Meganium is Casey's first and primary Pokémon. She obtained it as a Chikorita from Professor Elm's lab. It first appeared in The Double Trouble Header. It evolved into Bayleef in The Bug Stops Here, and again into Meganium some time before Here's Lookin' at You, Elekid!.

Casey's Pidgey
Casey's Pidgey was seen for the first time in Casey's battle with Ash in The Double Trouble Header, her debut appearance. It was easily defeated by Ash's Charizard. It was also later used to battle against Team Rocket.

It is likely that Pidgey, like Rattata, was chosen as a reflection of Casey being a beginning Trainer at the time. While Meganium, Beedrill, and Elekid are often seen out of their Poké Balls, Pidgey has not been heard of since Casey's debut episode.

Pidgey's only known move is Quick Attack.

Debut The Double Trouble Header
Casey's Rattata
Casey's Rattata was seen for the first time during Casey's debut appearance in The Double Trouble Header as a wild Pokémon. She battled it with her Chikorita and then caught it. Rattata was soon called out during Casey's battle against Ash, where it was quickly defeated by his Charizard. It was also later used to battle against Team Rocket. It reappeared in a flashback in The Chikorita Rescue.

It is likely that Rattata, like Pidgey, was chosen as a reflection of Casey being a beginning Trainer at the time. While Meganium, Beedrill, and Elekid are often seen out of their Poké Balls, Rattata has not been heard of since Casey's debut episode.

Rattata's only known move is Tackle.

Debut The Double Trouble Header
Casey's Beedrill
Main article: Casey's Beedrill

Beedrill was initially caught by Ash in the Bug-Catching Contest in The Bug Stops Here. Ash gave it to Casey afterwards because of her love for yellow and black-striped Pokémon.

Casey's Elekid
Elekid first appeared as a wild Pokémon where it interrupted a picnic that Ash and his friends were having. Casey came by and noticed the Elekid after defeating Team Rocket the second time in the episode. As Elekid is the pre-evolution of her favorite mascot of the baseball team, Casey challenged it to a battle with her Meganium. Even though it put up a great fight, it was no match for Meganium's strength. As a result, Casey was able to catch Elekid. Since Elekid was caught, Larvitar felt sad as it wasn't able to see its newly made friend. Casey promised to take care of her newly captured Pokémon and friend. Elekid appeared next to Casey and Meganium when Casey said goodbye to Ash and his friends singing the song of the Electabuzz team.

Elekid made a cameo in Address Unown! where it was shown in Larvitar's memories. It also appeared in A Date With Delcatty where it battled Georgio's Delcatty and lost, and in Those Darn Electabuzz where it helped Casey and her other Pokémon to try to resolve a phobia of Fire-type Pokémon.

Elekid's known moves are Thunder Shock, Thunderbolt and Thunder Punch.

Casey's Weedle
Casey caught Weedle at the Bug-Catching Contest in The Bug Stops Here. As she didn't win, it was released under the rules of the contest and as such very little is known about it.
