Tsu'tey

Initially, Tsu'tey appears to be an aggressive and sometimes ruthless warrior, making no attempt to hide his dislike for humans, whom he considers cowardly and unworthy of respect. However, in the eyes of his fellow tribesmen, Tsu'tey remained a proud and fierce defender of the clan, willing to sacrifice anything for the safety of the Omaticaya. Even after the RDA shuttle's suicidal attack, which left him mortally wounded, Tsu'tey cared more for the safety of his people than for his own injuries.

Despite his upbringing as a future chieftain and his excellent leadership qualities, Tsu'tey was a rather sensitive individual: the destruction of the Tree of Voices grove deeply wounded him, as did Neytiri's choice to marry Jake. Also, while very proud, he was not ashamed to admit his own mistakes and was deeply loyal to those who earned his respect. During the battle for the Tree of Souls, he became a trusted companion to Jake, whom he confidentially called "brother." Na'vi skin is bluish-blue, with a distinctive pattern of dark stripes and spots, as well as bioluminescent markings. The Na'vi have large, golden-yellow eyes, suggesting a nocturnal or crepuscular lifestyle. A long, thin tail helps the Na'vi balance when walking and jumping and serves to express emotions. The Na'vi also have flexible, pointed ears.
