Metcaine

• Tulkuns: Enormous, highly intelligent, four-eyed cetaceans who surpass many Na'vi in ​​intelligence and emotional development. Each member of the Metkayina clan has a Tulkun "spirit brother" or "spirit sister." Once a year, they reunite to share songs, stories, and grief. Tulkuns are completely pacifistic and never shed blood.
• Ilu: Elegant, plesiosaur-like creatures that are the Metkayin's equivalent of Earth horses or forest direhorses. The Na'vi form a neural bond with them (called sahelu) and use them for speed, fishing, and reef exploration. Ilu are very affectionate, playful, and easily tamed.
• Tsurak: Powerful, aggressive winged fish (crocodilefish) capable of gliding above the water. They are much larger and more dangerous than the illu. Only the most experienced and powerful warriors of the clan ride tsuraks, using them as war mounts.
• Akula: A fearsome apex predator of the reefs, resembling a land shark but with a massive, armored mouth that opens into four sections. An attack by an Akula is deadly, and defeating one is a sign of great valor for a young hunter.

• Skin color: Has a light turquoise or aquamarine hue (as opposed to the deep blue of the forest Na'vi). This provides excellent camouflage in clear water.
• Body structure: Their forearms, shins, and tails are noticeably expanded. Their tail is flat, muscular, and paddle-shaped, which allows them to swim at great speed and maneuver through currents.
• Eyes: Noticeably larger, with a special transparent nictitating membrane (third eyelid) that protects the cornea from sea salt and allows clear vision underwater.
• Breathing: Metkayina have increased lung capacity and are able to hold their breath underwater for tens of minutes. They use a special meditative breathing technique, which they control from the very center of their body.

Culture, everyday life and technology

• Where and how they live: Their original home is the village of Awa'atlu, built on the giant intertwined roots of mangrove trees. Their houses (marui) are woven from durable seaweed and fibers and hang directly over the water.
• Worldview: They believe the sea is the beginning and end of everything. Water gives life and takes it away, connecting them to the Great Mother Eywa. The clan leads an exclusively ecological lifestyle, taking from the ocean only what is necessary for survival.
• Tattoos: Adult warriors' bodies are covered with intricate designs reminiscent of Polynesian (Maori) tattoos. Each tattoo chronicles the hunter's exploits, status, and connection to the sea.• Tulkuns: Enormous, highly intelligent, four-eyed whale-like creatures that surpass many Na'vi in ​​intelligence and emotional development. Each member of the Metkayina clan has a Tulkun "spirit brother" or "spirit sister." Once a year, they reunite to share songs, stories, and grief. Tulkuns are completely pacifistic and never shed blood.
• Ilu: Elegant plesiosaur-like creatures that are the Metkayin's equivalent of Earth horses or forest direhorses. The Na'vi establish a neural link (sahelu) with them and use them for quick travel, fishing, and walking.

• Her chest is covered by an elegant braided top made of fine threads and fibers, decorated with rare beads and small shells.
• On her hips she wears a light loincloth made of cords and seaweed, which does not at all restrict her movements while diving.

Where does he live?

She lives on Pandora, in the coastal village of Ava'atlu, in her family's marui (tree root house), and spends her days among the coral reefs, teaching the forest Na'vi the art of underwater breathing and friendship with sea creatures - the illyu.

Tsireya is an incredibly kind, sensitive, compassionate, and open-minded girl. She has a soft heart and a genuine curiosity about the world.
• Towards Outsiders: From the very first meeting, she showed exceptional friendliness, warmth, and hospitality to Sally's family. While the other reef Na'vi mocked the forest dwellers, Cirea volunteered to teach them Metkayin culture. A deep romantic attachment and mutual sympathy quickly developed between her and Jake's second son, Lo'ak.

• Age: She is approximately 14-15 years old.

Where does he live?

He lives with his family on Pandora, in the reef village of Ava'atlu, spending most of his time in the water, training in illu riding and hunting.

Aonung is a young warrior who is strongly influenced by his peers and strives to establish his authority among the teenagers.
• Towards Outsiders: Initially, he was shown to be arrogant, condescending, and hostile. He openly mocked Jake Sully's children (especially Kiri and Lo'ak) for their anthropomorphic facial features and five fingers, calling them "demons." His mockery led to a fight, and he later played a cruel prank on Lo'ak by luring him over a reef into dangerous waters. However, after realizing his guilt and facing danger, he reformed and became a staunch ally.

• Reef Na'vi Anatomy: He has light, turquoise skin with soft, wavy stripes. Like all Metkayina, he has broader forearms, a flat, paddle-like tail, and thick skin on his feet adapted to water. He does not yet have the massive tattoos of his father, as he is not yet a fully-fledged adult warrior.
• Hair: Dark, styled into neat, thin braids (dreadlocks), which are gathered into a high, tight bun at the top of the head and fall freely onto the neck at the back.

• A wide leather belt with braided elements and hanging cords is fastened around his hips. In his hands he holds a traditional long spear of the Metkayina with a broad tip. Like Ronal, he lives on Pandora, in the coastal village of Ava'atlu, ruling the Metkayina clan in the middle of endless tropical reefs.

Tonowari is the Olo'eiktan (supreme chief) of the Metkayina Reef Clan. He embodies the image of a wise, prudent, and just ruler.
• Towards Outsiders: Unlike his wife, Tonowari is more diplomatic, hospitable, and reserved. Despite his initial wariness of Sally's family, he honors the ancient Na'vi laws of sanctuary and agrees to accept the refugees, urging his clan to treat them as brothers and sisters.
• Towards children: A loving, but strict and demanding father. He expects his children (Cireya and Aonung) to behave exemplary, befitting their status, and severely scolds his son for any misbehavior or disrespect for guests.
• Towards his wife (Ronal): He treats her with the deepest respect and tenderness. He sees her not just as a spouse, but as an equal leader, always consults with her before making important decisions and fiercely protects her in times of danger.
• To the clan: A responsible and selfless leader. His main goal is to maintain peace, security, and the isolation of his people from the wars of the "sky people." For the sake of protecting the clan, he is ready to make difficult compromises.• 9 feet 2 inches (about 280 cm). He is incredibly tall and has a powerful, athletic build.
• Age: He is approximately 35 to 40 years old by Na'vi standards.
• Reef Na'vi Anatomy: He has light turquoise-blue skin, a broad chest, and well-developed, muscular forearms. His tail is paddle-shaped for efficient swimming. Tonowari's face and body are heavily covered with intricate traditional tattoos, emphasizing his status as a great warrior and leader.
• Hair: Black, styled in neat, thick dreadlocks and braids gathered at the back of his head, revealing his face.

• A complex multi-layered skirt made of seaweed, ferns, long cords and grass fibres is attached to the hips.

Ronal is the Tsahik (spiritual leader and high priestess) of the Metkayina sea clan. She possesses an incredibly strong, proud, and warlike character.
• Towards Outsiders: Initially extremely distrustful, suspicious, and stern. When Jake Sully's family arrived seeking asylum, she treated them with open disdain, criticizing their physical features (thin tails and extra fingers inherited from humans). However, upon seeing sincerity in them, she shows mercy and later teaches Neytiri how to be in harmony with the ocean.
• Towards children: A strict, but deeply loving and devoted mother. In protecting her children and her home, she is ready to make any sacrifice.
• To her husband (chief Tonowari): Ronal is a faithful wife and equal co-ruler. There is absolute mutual respect between them; Tonowari always listens to her spiritual opinion and authority.

• Reef Na'vi Anatomy: Unlike the forest-dwelling Na'vi, Ronal has lighter, turquoise-green skin. Her forearms and shins are broader, her tail is flat and paddle-like, aiding in swimming, and her eyes are large, expressive, and a light bluish-green. Bioluminescent dots and traditional tattoos similar to Maori designs are visible on her body.
