The Lumiose Conference is the championship competition in the Kalos League, held in Lumiose City.
Competition
Opening ceremonies
The opening ceremony consists of two women releasing multiple Fletchling from a large-sized Poké Ball and Champion Diantha welcoming the competing Trainers.
Rounds
Preliminary rounds
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.
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.
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.
Finals
The finals consist of a Full Battle. When all six Pokémon on one side are deemed unable to battle by a referee, the Trainer loses, and their opponent is declared the winner of the Lumiose Conference.
