Battles held in the Battle Maison differ from regular battles in a number of ways.
Its background music theme, Battle Maison (also shared with the Battle Chateau), is a remix of Battle Tower (Johto) from Pokémon Crystal, Heart Gold and Soul Silver.
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. Although the player cannot expand the selection via Friend Codes in this game, the AI partners may use Mega Evolutions, potentially making them more useful than the ones available in Pokémon X and Y.
The right attendant deals in held items to be used in battle, adding the Luminous Moss and Snowball that can otherwise be found out on the field in Kalos.
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.
A Super version of each format is unlocked when the player first beats the Battle Chatelaine for the format, such as Super Single Battle.
