From Bulbapedia, the community-driven Pokémon encyclopedia.
The Alola League (Japanese: アローラリーグ Alola League) is the regional Pokémon League of the Alola region. The Alola League is composed of the Alola Elite Four members, along with the Champion. Recently founded by Professor Kukui, the Alola League does not yet have Gym Leaders. Instead, Pokémon Trainers from Alola recognized for their strength, such as those who have completed the island challenge, are invited to challenge the Elite Four at the Pokémon League building on top of Mount Lanakila, where the final island challenge was once held. The position of Champion is also initially vacant within the Alola League; Professor Kukui himself stands in as the final obstacle challengers must overcome before they can be dubbed Alola's first Champion. The first Champion is then able to defend the title against other challengers.
- The Alola League is the only League with more female Elite Four members than male ones.
- The Alola League is the only League in which any Elite Four members — Hala and Olivia — are battled prior to the player's encounter with them as Elite Four members in the same game.
