The guardian of the Kokiri is the Great Deku Tree, and their self-appointed "boss" is Mido. All Kokiri are ageless, and while they appear as Hylian children, most have existed for centuries prior to the events of Ocarina of Time. Each Kokiri has a guardian fairy that functions as a friend, parent and teacher. The Kokiri are known as "the spirits of the forest" and were possibly created by the Great Deku Tree, although according to the official Nintendo strategy guide, they were originally Hylian children that wandered into Kokiri Forest and were transformed by the mystical powers of the region. They are well-known for their distinctive and traditional green garb.
The symbol used to represent the Kokiri is reminiscent of the shape of the Kokiri's Emerald, the Spiritual Stone of Forest. This symbol is found on the Deku Shield and as engravings inside the Forest Temple.
