Psyduck uses a mysterious power. When it does so, this Pokémon generates brain waves that are supposedly only seen in sleepers. This discovery spurred controversy among scholars.

When its headache intensifies, it starts using strange powers. However, it has no recollection of its powers, so it always looks befuddled and bewildered.
