The Matoran of Mata Nui have formed the Matoran Guard, seeking to find and protect their fellows who are so often abused and overlooked by stronger, more powerful beings.  They are on good terms with most Toa, and frequently work with them to accomplish their mutual goals.  Though the Matoran lack many of the natural abilities that empower other factions, they more than make up for it in numbers and unswerving dedication to the people of the Great Spirit.

Underestimated by many due to their stature and lack of powers, the Matoran are actually one of the most numerous and adaptable species in the universe - a fact that is reflected in their fighting techniques.  Those who assume that the Guard is nothing but a band of “mere Matoran” do so at their own peril, as many a foe has discovered first-hand.  With the virtue of Unity, the Matoran Guard works and fights as one, though combat was not always a Duty that they had expected to take up, and their Destiny is left unclear in these troubled times.  On the island of Mata Nui, the Matoran learned to live in harmony with the natural world around them, as well as the Rahi beasts that inhabit it; as a result, the Guard’s forces also incorporate the various creatures they have tamed or befriended.  

The Matoran Guard is led by a great number of commanders, many of whom were the heroes of their respective villages prior to the war: Jaller, Onepu, Kongu, Hewkii, Hahli, Nuparu, Matoro, and more are held in the highest regard by their people.  Each commander uses a different set of tactics, catching the enemy off-guard as the Matoran change formations to adapt mid-battle.  The Guard’s noble Turaga elders offer guidance and protection, as well as heralding the arrival of the Toa Heroes for joint operations.
