The Johto League is the regional Pokémon League featured in the Johto region, introduced in Pokémon Gold and Silver games. It consists of eight Gym Leaders, each specializing in different types of Pokémon, whom trainers must defeat to earn Gym Badges. After collecting all badges, trainers can compete in the Johto League Championship, where they face top challengers, including rivals. The Johto League is notable for its diverse Pokémon and the introduction of several new species compared to the Kanto region.
Get all gym badges of Johto and defeat the Pokemon league. Then you have access to the Kanto Region.
