The setting for the competition
The Lumiose Conference (Japanese: ミアレ大会 Miare Conference) is the Kalos League general championship competition.
The conference is held in Lumiose City, but unlike most other League conferences, the conference isn't held there annually, and its location was only revealed shortly before the competition, with the League Stadium still being under construction at the time of the announcement. The conference began in A League of His Own! and concluded in Down to the Fiery Finish!, with the closing ceremony being interrupted by Team Flare attacking the city with Z2 and causing massive damage to it and the stadium.
The opening ceremony consists of two women releasing multiple Fletchling from a large-sized Poké Ball and Champion Diantha welcoming the competing Trainers.
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 quarter-finals.
The quarter-finals begin when only eight Trainers remain out of the 64 competing Trainers. The quarter-finals 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 semi-finals.
The semi-finals 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.
