Minish

The Minish (known to the Hylians as the Picori) first appeared in The Legend of Zelda: The Minish Cap. They are a tiny race the size of a thumb and can only be seen by good, well-behaved children. According to legend, they came from another world; this world can be reached when a door within Hyrule Castle courtyard opens once every century. It is said that when monsters threatened mankind, the Minish gave a legendary sword and a golden light to a courageous man, now known as the Hero of Men, destined to ward off the monsters.

Notable Minish (Picori):
 * Ezlo - Transformed into the Minish Cap in the game of the same name.
 * Vaati - An evil demon from all the Four Sword games; originally a Picori.
