Matau

Matau was the Toa of Air on Metru Nui.

Toa Metru
Matau was the Toa Metru of Air and guardian of Le-Metru. As a Matoran Matau was a top Ussal Crab driver who loved to see how many speed records he could break-and indeed, he had just finished crash-landing yet another prototype transport vehicle when Toa Lhikan handed him his Toa Stone. Of all the Toa, he was the most excited about being a hero and couldn't wait for all the public acclaim he was sure he would get. He was proud, impulsive, and headstrong, and willing to take a risk to prove to others that he was worthy of being a "Toa-hero." Matau wanted to be close friends with Nokama, but she was not interested in him. He had nothing against Vakama, but thought he would be a better choice for leader of the Toa Metru. As for the other three Toa Metru, Matau felt that they take the whole experience too seriously and should really lighten up. When in his Toa form he frequently collided with objects in various ways.

Matau wore the Kanohi Mahiki, the Great Mask of Illusion, which not only allowed him to create illusions but actually to shapeshift. He could duplicate the voices of those he impersonates, but did not assume their powers. He carried two Aero-Slicers, which were strong enough to cut through energy fields and could also serve as glider wings and rotors. They also channeled his elemental air power.

Toa Hordika
As a Toa Hordika, Matau is the one most eager to seek out Keetongu. His Fang Blades can cut through most substances, and serve to charge his Air Rhotuka. He is willing to do anything to reverse the mutation and become a Toa Metru again. Sickened by the transformation into Hordika, Matau however still retained his funny side. He blamed Vakama for his transformation and often called him "Mask-Melter" or "Smelt-Head". During his time with the others and the incident of the Great Temple, he finally realized what he had done wrong and vowed with the other Toa that they would do whatever to rescue Vakama, who, from their point of view, had given in to his Hordika side. At the last battle against the Visorak, Matau finally understood the meanings of Unity, how hard is it to be leader and no matter how he looks, there is always hope. It was also he who saved Vakama from being plunged into the shadows. Matau contributed to the six elemental spinners which, unknown to them, freed Makuta from his Protodermis prison.

Matau was finally returned to his Toa-hero form by the great Rahi Keetongu. He helped load the Matoran onto airships and take them to Mata Nui.

Matau, along with the other Toa Metru, sacrificed his Toa power to revive the Matoran. This changed him into a Turaga. Fortunately, on their first visit to Mata Nui, the Toa Metru had given a little of their power into Toa Stones and scattered them about the Island. This was a wise move, because the dark times for Matau and his Matoran were just beginning...

Turaga
As Turaga of Le-Koro, he was an Ussal cart driver in Metru Nui. Matau is known for his practical jokes, but is always calm in a crisis and never asks the Le-Matoran to do something he is not willing to do himself. Like all Le-Matoran, he commonly uses "Treespeak" slang. When faced with a fork in the road he always advises going right (as he had some bad experiences with left forks as a Toa Metru). He carries the Kau Kau Staff (named after the call of Brakas monkeys). When Matau and the Matoran returned to Metru Nui, He and the other Turaga learned that Mata Nui was dying.
