Poké Fan (Trainer class)
From Bulbapedia, the community-driven Pokémon encyclopedia.
A PokéFan (Japanese: だいすきクラブ Daisuki Club, or (Member of the Pokémon) Fan Club) is a type of Pokémon trainer that first debuted in the Generation II games. They come in two varieties: Middle-aged women with Poké Dolls and middle-aged men with small children dressed in Pikachu outfits.
They raise many different cute Pokémon that usually belong to the Fairy Egg group. Also, their Pokemon are notable in that they always hold a Berry or Oran Berry, depending on the game.
