Idol
From Bulbapedia, the community-driven Pokémon encyclopedia.
An Idol (Japanese: アイドル Idol) is a type of Pokémon trainer that first debuted in the Generation IV games. There is only one proper trainer from Idol class, an Idol Grace, who is found in the Jubilife City TV station. Other Idols can be randomly battled at Battle Tower. They are teenage girls dressed up in elaborate pink pop star outfits with a microphone.
They mostly use cute Pokémon from the Fairy egg group, such as Pikachu and Clefairy, in battle.
