Erika is the Gym Leader of Celadon Gym located in the heart of Celadon City. Trainers that defeat her in a gym battle are awarded the Rainbow Badge as proof of defeating her. She specializes in Grass-type Pokémon as well as selling and making perfumes.
As well as running her gym, she also runs a perfume store nearby where she is the manager. Erika
believes that perfume has the effects of relaxing people's moods, invigorating them and healing their hearts. When Ash Ketchum
entered her perfume store and mocked it as just a means of making guys fawn over girls, he was kicked out of the store and then later out of the Celadon Gym as well. She instructed her subordinates to not allow him to enter the gym because of his perfume remarks.
Essence of Gloom
Team Rocket heard about a legendary perfume that is made in the Celadon Gym and attempted to steal it. They tricked Ash Ketchum
into working with them so they could enter the gym undetected. They ended up destroying the Celadon Gym in a large fire before they stole what they thought was the formula but instead it was Gloom extract which is used as raw material for perfume.
Gym Battle with Ash
Since Ash Ketchum
was banned from the gym, he couldn't challenge Erika
to a battle. He snuck in disguised as a girl and called himself 'Ashley' (Sato-chan). Pikachu
realized it was him and since he was discovered he challenged Erika
to a battle on the spot which she accepted. She setup the battle as a 3-on-3 but the battle was never fully completed. Her Tangela was sent out first and it managed to defeat Ash's Bulbasaur
with a Stun Spore
, which paralyzed it. Realizing that his Grass on Grass battle technique wasn't working against Erika
, Ash Ketchum
sent out his Charmander. Erika
then told Ash Ketchum
she'd give him a Paralyze Heal after the battle which showed her loving and compassionate side. Erika's Weepinbell
was sent out second to counter Ash's Charmander
but its Flamethrower
proved to be too much for it.
In the final matchup, Erika's Gloom
was sent out to battle Ash's Charmander
and Ash's Charmander
couldn't stand the horrid smell of Erika's Gloom
and was recalled. Pikachu
was going to be matched up with it for the final round of the battle but Team Rocket exploded a bomb in the gym and it caught fire. Everyone except Erika's Gloom
escaped safely, so Ash Ketchum
decided to go in after it as he thought he was partially responsible for the disaster. As thanks for rescuing her Gloom, Erika
gave Ash Ketchum
the Rainbow Badge.
