The Gym is designed like a dollhouse, or like a house seen in fairytales, befitting of its designatedFairy type. In order to battle Valerie, the player must go through awarp panel puzzle, much like theSaffron Gym inKanto. After Valerie has been defeated, a one-way warp panel in her room can be used to return back to the entrance.
The table below shows how the Gym's teleporters are interconnected. The colors are meant solely as a visual aid.
The Gym appeared inA Fashionable Battle!. Its exterior appearance is similar to thegames, though it also has a catwalk, which is used for fashion shows hosted byValerie. During one of said shows, Valerie allowedSawyer to have an official Gym battle with her. However, Sawyer was soon defeated, leaving him without aBadge for the time being.
The Gym's battlefield was shown inFairy-Type Trickery!. It is a garden with wall-mounted digital displays, which are used when Valerie is making her entrance.Ash had a Gym battle with Valerie, eventually emerging victorious and earning his sixthKalosBadge.
Spritzee is Valerie's first known Pokémon. It first battledSawyer'sBagon. Bagon'sDragon Breath had no effect on Spritzee. After easily dodging Bagon'sHeadbutt attacks using its agility, it defeated Bagon withDazzling Gleam.
Sylveon was briefly seen in its first appearance with the other Pokémon before Valerie went on the catwalk.
Sylveon reappeared inFairy-Type Trickery!, where it battled Ash. Even though it provided a tough challenge for Ash's Fletchinder, it was eventually taken down with a supereffectiveSteel Wing.
