Pokémon Red and Green Versions/Features/Gyms

As would become the case for each Pokémon game in the core series to come, there are eight Gyms in Kanto, each with their own type affiliation. The Gym Leaders are: Brock (Rock) at Pewter City, Misty (Water) at Cerulean City, Lt. Surge (Electric) at Vermilion City, Erika (Grass) at Celadon City, Koga (Poison) at Fuchsia City, Sabrina (Psychic) at Saffron City, Blaine (Fire) at Cinnabar Island, and Giovanni (Ground) at Viridian City.
