Neteyam te Suli Tsyeyk'itan

Personality - Kind, responsible and possessing strong virtue, Neteyam was the "perfect son” of the Sully family whose example the other children were to supposed to follow, as he held himself to a high standard.[4] Due to resembling the Na'vi physically (lacking eyebrows and having one less finger on each hand), Neteyam did not have to face the same insecurities that Lo'ak and Kiri had to which got to both of their self-esteems. However, he is never seen condescending the two because of their avatar/human DNA.

Inheriting a blend of Jake's and Neytiri's noble and honorable nature, Neteyam carried himself with a strong, confident demeanor and was well-liked by his clan. Even other Clan Leaders, like Akwey and Ikeyni, spoke warmly about Neteyam and praised how much he resembled his parents especially his mother Neytiri and how well he was growing.[5] Neteyam desired to be a great leader and a warrior like his father, but his age, Jake's protective nature, and his siblings' antics undermined his attempts to prove himself.

Neteyam took his role as the eldest son seriously, and was often tasked by his parents to keep an eye on his siblings. Jake and Neytiri viewed him as reliable and would take him on many of their missions. He strove to set a good example for them. When he was older, he was very protective of his siblings and focused more on keeping them safe than having fun with them. In moments of peace, Neteyam let himself joke, tease, and banter with his siblings, such as showing amusement at Lo'ak's poorly hidden attraction towards Tsireya.

Neteyam never complained about the drastic changes that was hurled his way, and seemed to take everything into stride. It was only when he was dying that he showed his true feelings and voiced his wishes about returning home and living a peaceful life. When his memory is visited within the Spirit Tree, he is seen as a child sharing a proud accomplishment with his father in nature. A reasonable explanation for this is that Eywa sensed Neteyam's will to return home and experience a simpler time before the war, hence Jake and Neytiri perceive him as a carefree child within his memory.

However, he also changes to his current age briefly. He is no longer wearing any of his warrior items such as his armguards or even his cummerbund; instead he is only wearing his usual choker that he wore in the forest (instead of the warrior neckpiece he wore at the ocean), making it possible their connection to home is what he wished to share with his father, as well as define his memory.

Neteyam was a natural athlete; he is talented and excelled at all things, being nearly unmatched in hunting prowess among the other young members of the Omatikaya clan. His ikran flying was almost as adequate as his mother's. He was an expert at archery and was the youngest of the Omatikaya clan to make a clean kill on a sturmbeest hunt.

Physical - Neteyam te Suli Tsyeyk’itan has a striking presence that reflects both his Na’vi heritage and his role as the eldest Sully child. Tall and lean, he carries the athletic build typical of the forest-dwelling Omaticaya, his movements fluid and agile from years of training in hunting, climbing, and combat. His skin is a smooth blue marked with darker stripes, and delicate bioluminescent freckles trace organic patterns across his face and body, glowing softly in low light.

His facial features are refined and expressive, showing a clear blend of Jake’s steadiness and Neytiri’s grace. Neteyam has large golden-yellow eyes that convey both warmth and a sense of responsibility beyond his age. His cheekbones are high and sculpted, his ears long and pointed, and his nose broad and feline like that of the Na’vi. His dark hair is worn in traditional braids adorned with beads and small woven ornaments, symbols of family and achievement, with his long queue braid trailing behind.

Neteyam’s clothing is practical and lightly decorated, suited for movement and training. He wears a loincloth, a beaded chest harness, armbands, and utility pieces that show his status as a young warrior in formation. When the Sully family joins the Metkayina reef clan, he incorporates subtle elements of their style as well, including lighter water-adapted accessories, shells, and reef-colored beads. Altogether, Neteyam’s appearance embodies youthful strength, duty, and the quiet nobility expected of the family’s firstborn.
