The setting for the competition
The Lumiose Conference (Japanese: カロスリーグ・ミアレ大会 Kalos League Miare Conference) is the Kalos League general championship competition. All Pokémon Trainers who have earned eight Gym Badges from the Kalos region are eligible to enter. It is held in Lumiose City, but unlike most other League Conferences, the competition is not held there annually, and its location was only revealed shortly before the competition, with the stadium still being under construction at the time of the announcement.
The tournament began in A League of His Own! and concluded in Down to the Fiery Finish!, with the closing ceremony being interrupted by Team Flare, who attacked the city with Z2 and caused massive damage to it and the stadium.
Before the competition starts, a party is held where contestants can interact with one another.
In the opening ceremony, multiple Fletchling are freed from a large-sized Poké Ball while Diantha, the Kalos League Pokémon Champion, welcomes the competing Trainers and delivers an encouraging speech. She observers the entire competition along with Professor Sycamore.
Malva, a member of the Kalos Elite Four, works as a reporter and is shown interviewing participating Trainers and reporting what happens during the competition. She had a disguised Team Rocket working for her as her camera, sound, and lighting assistants for the broadcasts.
The scoreboard for the Full Battles
The preliminary rounds consist of three-on-three matches with random match-ups decided by a computer. When all three Pokémon on one side are deemed unable to battle by a referee, the Trainer is knocked out of the tournament. In the first round, the 64 competing Trainers are reduced to 32 Trainers. This continues with each round until there are only eight competitors left for the quarterfinals.
The quarterfinals begin when only eight Trainers remain out of the 64 competing Trainers. The quarterfinals consist of three-on-three matches, identical to the match set up in the preliminary rounds. When all three Pokémon on one side are deemed unable to battle by a referee, the Trainer is eliminated. The four winning Trainers will move on to the semifinals.
The semifinals consist of Full Battles. When three Pokémon on one side are deemed unable to battle, both Trainers take a short break while the battlefield is changed. When all six Pokémon on one side are deemed unable to battle by a referee, the Trainer is eliminated. The two winning Trainers will move on to face each other in the finals.
