Pokémon League Conference

A Pokémon League Conference is an championship tournament that is hosted seemingly annually in several regions in the Pokémon world. Pokémon Trainers must register for the region's Pokémon League, something which they can do at seemingly any Pokémon Center or with a Pokémon Professor, and then must win at least eight of the region's Gym Badges in order to be able to register for the competition. In addition to this method, the Indigo Plateau Conference is known to accept trainers who have passed the Pokémon League Admissions Exam or graduated from Pokémon Tech.

Rules vary from region to region, but generally, championship competitions are divided into three parts: qualifying rounds, preliminary rounds, and final rounds. Highly skilled Trainers will move on to compete with a smaller pool of competitors. The Trainer that defeats all other competitors is deemed the winner of the competition. Losing Trainers who participate in the competition will be ranked accordingly.

In Alola, due to the lack of Gyms in the region and the fact that its Pokémon League was only recently established, no specific conditions need to be met in order to enter its League Conference, and its winner was directly declared as the first-ever Champion of Alola. The newly-crowned Champion subsequently faced the League's founder, Professor Kukui (originally intended to appear as the Masked Royal), in an exhibition match.

Champion League
After winning a Pokémon League Conference, a Trainer may enter the Champion League of the relevant region, where the Elite Four and the League Champion await. Like in the games, Trainers must defeat all members of the Elite Four for the right of challenging the Champion. Once the Elite Four is defeated, Champions are required to defend their title from challengers. If the battle against the challenger is won, Champions hold on to their current status. However, if the challenger succeeds, Champions must relinquish their title to the winning Trainer, who will then be deemed the new Pokémon Champion.
