Shauna appears in Pokémon X and Y as a friend of the player. Shauna is apparently energetic and curious about her friends' progress in their travels. She also enjoys solving puzzles, and is a friend of Clemont and Bonnie.
After the player becomes Champion, she will trade the player the starter Pokémon which is weak in typing to the one the player originally chose in exchange for any Pokémon owned by the player.
Shauna also appears as one of the player's partners in the Battle Maison when choosing Multi Battle.
