Psyduck is a duck-like Water-type Pokémon from the Pokémon series, known for its perpetual headaches that leave it stunned and standing vacantly, trying to calm itself. When the headache intensifies, its brain cells awaken, enabling powerful Psychic-type moves beyond its usual capability. In the anime, it serves as comic relief, often accidentally released by Misty instead of her intended Pokémon. It evolves into Golduck with enough experience and appears in various media like Pokémon Detective Pikachu as Lucy Stevens' partner.
