Avatars retain the human configuration of five digits on each hand and foot, as opposed to the native Na'vi who possess four digits on each limb. Avatars possess eyebrows, while the Na'vi are hairless apart from their scalp and a small tuft of hair on the tips of their tails.
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.
Using their capability of advanced genetic engineering, humans develop "Avatar" hybrid bodies from genetically distinct modified human DNA and Na'vi alien genetic material. Through psionics, genetically matched humans are then mind-linked to these "Avatars" for remote control operation.
An avatar is a biological shell or clone of a Na'vi-human hybrid, crafted with the combined DNA of a Na'vi and specific human volunteer. Avatars are used to help humans explore Pandora (a moon in the Alpha Centauri star system) without breathing equipment, as the atmosphere on Pandora is toxic to humans.
Neytiri te Tskaha Mo'at'ite is a fictional character in the Avatar franchise, created by James Cameron. She is portrayed by Zoe Saldaña. Zoe Saldaña as Neytiri in Avatar (2009). Neytiri is the feisty, beautiful princess of the Na'vi clan, Omaticaya.

How do avatars reproduce?
Na'vi are monogamous creatures and the process of their reproduction is similar to Terran mammals, as they do possess genitalia; however, though they nurse their young and possess belly buttons where they were once connected to an umbilical cord, the Na'vi are non-placental, thus the details of their internal biology ...
Because Grace had an avatar body, Kiri possesses human-like traits such as her eyebrows and five fingers on her hands. She also lacks the elongated canines common amongst the Na'vi.
The first reason why Neteyam has four fingers while his siblings all have five fingers might be simple genetics. Since an avatar is a hybrid of Na'vi and human DNA, it's easy to imagine the genes that control the number of digits in the body competing with each other.
Shortly after the events of the Avatar, Jake has the Na'vi give his human body a traditional burial and moves the Omaticaya Clan near Hell's Gate to be close to the human allies who were allowed to stay on Pandora.
Jake's story picks up fifteen years after the Battle of the Hallelujah Mountains and the expulsion of 90% of the humans on Pandora, and Jake is now living as a full Na'vi, his consciousness permanently fused into his avatar body.
Pandora's air is unbreathable due to high levels of carbon dioxide and trace amounts of hydrogen sulfide, posing a threat to humans. Humans use exopacks and avatar bodies to survive and explore Pandora's toxic atmosphere, but these solutions have limitations and challenges.
While in the Marines, Jake was promoted to the rank of Corporal and became an elite Recon Marine. He was then assigned to the Marine Corps First Reconnaissance Battalion, but later suffered a spinal injury in an unnamed war while fighting in Venezuela. The injury was severe, leaving him paralyzed from the waist down.
Most of them escape, save for Spider, and it's revealed that Spider's dad in Avatar is none other than the villain Quaritch. Quaritch and Spider suffer a complex dynamic throughout the film, with Spider ultimately saving his life in the end.
While Spider didn't actively do anything to specifically make Neytiri hate him before the sequel movie, saving Quaritch's life at the end of Avatar: The Way of Water certainly justified some of her distrust.
Jake asks why she saved him, and she admits it is because he has a strong heart. Neytiri told Jake that Sky People cannot learn and don't See, and that he should not be here as he does not know the ways of the forest. Dozens of woodsprites land on Jake.
How long do Na'vi live? Landau: The Na'vi age slower than humans, so they have a longer life span. In the burial scene in the film, that woman would be older than the equivalent-looking human.
Neteyam te Suli Tsyeyk'itan, or Neteyam, is a major character in the Avatar franchise, serving as one of the main characters in Avatar: The Way of Water. He is the 15-year-old eldest son of Jake Sully and Neytiri, who is also the older brother of Lo'ak, Tuktirey, and Kiri.
Unless that theory is true, Grace was impregnated by someone. Kiri's brothers joke that the scientist Norm could be her father. The movie does not reveal much information about the birth of Kiri. It is unclear whether Kiri was conceived before Grace died and her avatar carried her to term.
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.
Her father is not a father, her father is another mother, Eywa, the Great Mother, the sentient life force of Pandora itself that exists in all things there, but is rarely understood. So essentially yes, Kiri was born from Eywa just like Anakin Skywalker was allegedly conceived by the Force itself and its midichlorians.
Lo'ak and Kiri are 14 years old in Avatar: The Way of Water, while Tuk is only eight. So, it sounds as if the fourth movie will open with Lo'ak, Tuk, and Kiri at the same ages they are in the third installment, and then they will age six years following the time jump.
Lo'ak is old enough in Pandora to be a warrior and seems to be about 13 or 14 years old in Avatar: The Way of the Water given the time gap between Avatar and its sequel. It also appears that Neteyam and Lo'ak are close in age, so being a young 14-year-old would make sense.
In Cameron's script she's introduced with the descriptor "in human age she would be 18," but that raises as many questions as it answers. As with the math that leads to Jake being 28, Neytiri's birth in the Earth calendar year 2136 and the film's setting in 2154 add up to make her 18, but that's by Earth standards.
