Erika

Erika is the Gym Leader of Celadon City's Gym, known officially as the Celadon Gym. She hands out the Rainbow Badge to trainers who defeat her. She is a serene young woman who specializes in Grass-type Pokémon. She sometimes dresses in elegant kimonos and seems to represent traditional Japanese beauty, and perhaps geisha culture.

Erika has a kindhearted personality and takes on students to teach them about being a good Trainer and perfume manufacturing. However, she also possesses a temperamental side, particularly when her perfume is insulted. In battle, she uses status moves like Stun Spore to overwhelm her opponent's Pokémon.
