Minish Vaati
The true form of Vaati. Once an apprentice to Ezlo, he was interested in the evil within the hearts of humans. Using his Ezlo's wish-granting cap, the Minish Cap, Vaati turned himself into a sorcerer in the world of man.
Quote from The Legend of Zelda: The Minish Cap Minish Vaati figurine: "Before he became a sorcerer, he was a simple Minish. He had always been entranced by the evil that lives in the hearts of men.."
