The Johto League is a Pokémon competition that takes place in the Johto region, one of the main areas in the Pokémon world. It is known for its unique Pokémon and diverse environments, including forests, mountains, and lakes. Trainers compete to earn Gym Badges by defeating Gym Leaders in battles, which allows them to qualify for the Pokémon League at the end of the season. To participate in the Johto League, trainers must collect eight badges and then challenge the Elite Four and the Champion. The league is part of the larger Pokémon franchise, which includes video games, trading cards, and an animated series.
