Poké Kid

A Poké Kid is a type of Pokémon Trainer that debuted in the Generation IV games. They are little kids in Pokémon costumes.

In Pokémon Diamond, Pearl and Platinum (including their remakes), Poké Kids appear as children. Outside of battle, they appear to be just an ordinary Pikachu (in the original DS games); this is used to mess with the player on multiple occasions, including a Poké Kid hidden amongst several regular Pikachu. They exclusively use Pikachu, and in Platinum, Pichu and Raichu.

In Pokémon Sword and Shield, male Poké Kids were introduced, who take on the appearance of Pikachu, while girls wear Eevee costumes instead. Unlike before, they do not exclusively use Pikachu.
