By talking to the attendant next to the arena, the player may start a battle challenge to earn Battle Points (BP) and increase their current win streak, which will be displayed on their Vs. Recorder along with their all-time record win streak.
Number of eligible Pokémon
2 per player
A Super version of each format is unlocked when the player first beats the Battle Chatelaine for the format, such as Super Single Battle. The normal battle formats are limited to streaks of 20, ending after battling the Battle Chatelaine.
Battles held in the Battle Maison differ from regular battles in a number of ways. When challenging the Battle Maison:
All Pokémon above level 50 will be set to level 50. Those under level 50 will remain at their current level.
Unlike previous games, the player receives Battle Points (BP) at the end of every victorious match. The number of Battle Points (BP) awarded after a match varies with the length of the current win streak, as shown in the table below.
20 (Battle Chatelaine)
50 (Battle Chatelaine)
Battle Chatelaines are sometimes fought instead of regular Trainers. Unlike regular Trainers who use a set of Pokémon randomly drawn from their roster, Battle Chatelaines have a predetermined team for every battle, although the team order does vary. The Battle Chatelaines also appear in Multi Battles, where they form teams. In Multi Battles, the Battle Chatelaines use two random Pokémon from the parties that match the level of challenge. A victory against a Battle Chatelaine on the 50th consecutive battle on any of the Super challenges will reward the player with a commemorative monument in the lobby of the Battle Maison. There are 5 monuments to be won in total, corresponding to each of the Super challenges, with the color matching that worn by the appropriate Battle Chatelaine (purple in the case of Super Multi Battle). After defeating the Chatelaine, the participants are awarded with a Skillful Battler Ribbon or an Expert Battler Ribbon.

Battle Maison Trainers
The Trainers faced in the Battle Maison challenges will normally have randomly-selected teams from a Trainer-specific roster of Pokémon. Each Pokémon will have a predetermined base stats (i.e. a fixed Nature, EVs and IVs). The gender and Ability will be randomly selected.
In the Multi Battle and Super Multi Battle challenges, the player can choose to partner with a friend or with the AI. Unlike the Battle Tower and Battle Subway from previous generations, the AI partners will always use the same two Pokémon (with the same moves, stats, gender and ability) each time the player registers for a challenge. However, the order that they send out their Pokémon appears to be random.
Pokémon X and Y
In Pokémon X and Y, the default AI partners consist of the player's rivals: Shauna, Tierno, and Trevor. The player can build on the list of available AI partners by registering Friend Codes to their profile. Each Friend Code will have a team of two selected from the set of Pokémon used by the Battle Maison's NPC opponents.
In Pokémon Omega Ruby and Alpha Sapphire, Wally will appear in the lobby to have a rematch with the player after the player achieves 50 consecutive victories. After being defeated for the first time, he will randomly reappear in the lobby, challenging the player with his strongest team. Wally has a 1% chance to give the player an Ability Capsule upon being defeated in a rematch.
A large amount of data from the Battle Maison appears to have been imported from its predecessor, the Battle Subway from Generation V:
Many of the Pokémon species (from before Generation VI) in the Battle Maison share the same movesets as their Battle Subway counterparts in the Super challenges. Additionally, none of the fully-evolved species that have been excluded from the Super challenges in the Battle Subway appear those of the Battle Maison.
Several Trainers from the Battle Maison in Pokémon X and Y have exactly or very similar quotes to those of similar Trainer Classes in the Battle Subway. A few even have the same name. However, almost all of the quotes and many of the names have been changed in Pokémon Omega Ruby and Alpha Sapphire.
