The Horse Clans of the Plain are an unknown number of clans of Na'vi, who, unlike the Omaticaya Clan, live in wide, open plains instead of jungle.
The clans specialized in cavalry, utilizing Direhorses. One or more of these clans are led by an unnamed Horse Clan Leader. When summoned by Toruk Makto, they assisted in the defense of the Tree of Souls during the final battle in Avatar. They played an important role in the conflict as ground cavalry, essentially attempting to halt the advance of RDA AMP Suits and infantry units. They sustained heavy casualties throughout the course of the battle, though the exact number is unknown.
They were supported by Norm Spellman in his Avatar form, and later in his human form, who helped to direct the ground assault by keeping in contact with Jake Sully using a throat microphone.
