Yadon, known in Japanese as ヤドン, is a Pokémon from the Pocket Monsters series. It is a slow, dopey-looking Water/Psychic-type Pokémon originally introduced in the Kanto region. Yadon is famous for its sleepy personality, sluggish movements, and vacant expression, which often make it seem unaware of its surroundings. In the series, it appears as a recurring Pokémon species and is sometimes used for comic relief. It also evolves into Yadoran when exposed to a certain item.
