The most obvious distinction between an avatar and a genuine Na'vi is the number of fingers and toes. A Na'vi only has four digits, while the avatar body has five due to the human DNA. At the end of Avatar, Jake decides to transfer his consciousness to his avatar body permanently.
While Jake and Neytiri's oldest and youngest biological children, Neteyam and Tuktirey "Tuk", have four fingers, seemingly taking after their mother, their middle child, Lo'ak, has inherited five fingers.
Although Tuk is an avatar/Na'vi hybrid, like Neteyam, she was born with four fingers and toes, and her face is browless, making her look like a full-blooded Na'vi. Due to her age, her hair is still quite short, though her braid is now completely long.
Avatars retain many of their human traits, like eyebrows and five toes. The most notable difference is that the Na'vi have four fingers, whereas the avatars have five.
Despite the mystery surrounding her conception, she is a naturally born Na'vi who was raised in the rainforests of Pandora. Her biological father, if she even has one, remains unknown. Because Grace had an avatar body, Kiri possesses human-like traits such as her eyebrows and five fingers on her hands.
Why does Tuk and Neteyam have 4 fingers? Neytiri passed on her four digit hand to their eldest son and their daughter and Jake passed his five digit hand to their second son. Genetics - as simple as that. Some kids get moms features, some kids get dads features.
It could be an immaculate conception. There's a theory that the film director James Cameron could be hiding a vital feature of the Na'vi. According to that theory, Na'vi could reproduce asexually. Unless that theory is true, Grace was impregnated by someone.
Augustine's colleague Norm Spellman (Joel David Moore) was the father and Grace conceived Kiri before the end of Avatar before somehow giving birth in her Avatar body. However, the more interesting theory is that Kiri is literally the child of Eywa due to some sort of immaculate conception.
Spider's Mother Is Paz Socorro (Revealed In Avatar Comics)
It has been confirmed through Avatar comics that Spider's mother is Paz Socorro. While Avatar: The Way of Water takes place a decade after the first movie, James Cameron's original sequel script did not have as big of a time jump.
The Soul Tree is the heart of Eywa, the goddess that guides all of Pandora. Avatar: The Way of Water illustrates that Kiri has a special connection to Eywa, which means she can wield powers and feel her more deeply than other Na'vi.
During the mating, the couple will connect queues in an act called tsaheylu. This creates a state of unified body consciousness, in which both parties access the physical sensations of the other. A single instance of this act will create a powerful emotional bond that lasts a lifetime.
A deleted scene from the end of Avatar (2009) revealed that Neytiri was pregnant, so Neteyam was born shortly after the events of the original movie. In accordance with the sequel's timeline, Jake and Neytiri's son Neteyam is nearly 15 years old in Avatar: The Way of Water.
Although lifespan data is incomplete, it is estimated Na'vi live 30% longer than the average human. Once born, Na'vi children mature more rapidly than humans, reaching mental, physical, and cultural adulthood between the ages of 15 - 17 Terran years.
He helped save Payakan from the whalers who just tagged him with a tracking device, intending to hunt him down and kill him. Neteyam removed the tracker and swam off with it on an ilu to lead the whalers away. He was shot at with sonar beacons, but he ultimately escaped unharmed. Neteyam killed by the bullet wound.
Aided by a few sympathetic (human) scientists, Jake successfully leads the Na'vi in battle by driving out the predatory humans. In the film's closing scene, the Na'vi transfer Jake into the avatar body permanently, eradicating his disability and neatly delivering him from his original role as a white colonizer.
Kiri is the inquisitive and intelligent adopted daughter of Jake Sully and Neytiri. Not long after Grace Augustine's death, her dormant avatar was discovered to be pregnant, and Jake and Neytiri adopted the child when she was born.
The seizure is believed to have been caused by frontal lobe epilepsy which could also cause the other symptoms Kiri has been having, including visions and the belief that she's hearing Eywa. However, the Metkayina clan believe it's down to something more spiritual and is a result of Kiri's connection to Eywa.
The eldest child of Neytiri and Jake Sully, Neteyam te Suli Tsyeyk'itan is a natural athlete. Noble like his father, he is favored by the clan for his strong and confident demeanor. He cares greatly for his siblings, often being asked to look after them while his parents are gone.
Though there were some theories about Kiri being a reincarnation of Grace, that isn't quite the case. Instead, Kiri's origins are a little more complicated. She was naturally conceived and born of Dr. Grace's Na'vi avatar, adopted by Jake and Neytiri, and raised in the rainforest.
What we do know is that Grace's last moments of consciousness in Avatar are tied to a Tree of Souls. She seemingly died during that ritual, but she also said that she was "with" Eywa, and we now know that while Grace might not be fully alive anymore, something of her essence was preserved in her Na'vi avatar.
How Was Kiri Born? Kiri was born after Grace died following a mortal bullet wound given to her by Quaritch, with her then-empty avatar giving birth to the child despite not having any consciousness.
The sequel introduced us to the extended Sully family, but they'll be missing a member in the third movie, as Neteyam (Jamie Flatters) was shot and killed during The Way of Water's dramatic climax.
“We're into a very hectic two years of post-production right now,” Cameron told Campbell about the third film in his decades-spanning franchise. “So it will be Christmas of 2025.”
(The odds of the Metkayina knowing any English is low and we saw Spider translating the Ta'unui clan's Na'vi to Quaritch.) So, essentially they are kids and are using a slang word that means 'brother,' so it's translated as 'bro.
