Spider, whom audiences initially thought was Avatar 2's hybrid Na'vi and human child, is actually fully human. Spider - real name Miles Socorro (played by young Jack Champion) - was born in Pandora's "Hell's Gate" colony sometime around the events of Avatar.
Spider is played by Jack Champion. Not only is he a child of the humans who stayed on Pandora after the initial eviction of the RDA at the end of Avatar, but he's Quaritch's son. Spider grew up around the Na'vi, spending time with Norm and Max in the labs and bonding with Jake and Neytiri's kids.
Cameron also said that Spider would serve as "the pivot point in between Quaritch and Jake." This could mean that Spider holds the key to Quaritch's redemption which could stop the endless blood feud between him and Jack.
Paz Socorro is Spider's mom after a romantic relationship with Quaritch led to her getting pregnant. She gave birth to Spider, whose birth name is Miles (just like his father), in 2154. However, Paz Socorro died shortly after that in combat during Avatar's finale.
Spider is similar to jake in that he fell in love pandora and the na'vi way as a human, but unlike jake he can never truly experience it. He can't even breathe it's air, or connect to eywa, and his own body is a constant reminder he will never be one of the na'vi.
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 was shown to have grown a strong bond with Kiri, with many speculating that there could be a potential future romance between the pair, while his tumultuous relationship with Neytiri came to a dramatic head in the final moments of The Way of Water's climactic battle.
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.
That being said, an avatar body using Spider's DNA would need to be created, and it takes around 5-6 years for one to be fully grown. It's possible that the human scientists such as Norm and Max who stayed on the world of Pandora and helped raise Spider might have created an avatar for Spider off-screen.
After Quaritch is revealed to be alive in the body of a Na'vi, he kidnaps Jake's children. Most of them escape, save for Spider, and it's revealed that Spider's dad in Avatar is none other than the villain Quaritch.
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.
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.
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.
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.
The relationship between Neytiri and Spider was developed well enough to justify what occurs in the third act of the film - this scene being where Neytiri has Spider by the throat with a knife in an effort to convince Quaritch to relinquish Kiri.
In the construction of the Na'vi species, there are undeniable influences from Black and Indigenous cultures. Both films show Na'vi characters depicted wearing dreadlocks and braids, hairstyles with historical connections to Black and African cultures.
Neteyam is the eldest child of Jake and Sully, and grew up with Spider. So, if Na'vi gestates for a similar period to humans, Neteyam is around fourteen years old. Lo'ak is the younger brother of Neteyam, but the two seem to be approximately the same age.
Like his father, the teenage Lo'ak starts out as the reckless misfit who steps into a brave role for his family. 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.
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.
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.
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.
Kiri is the biological reincarnation of Grace and everything that Grace was before she was shot by Colonel Quaritch. Through Eywa, Grace's memories and consciousness were imprinted on an embryo inside her avatar body. This close connection with Eywa allows Kiri to adapt effortlessly to the ocean.
Spider thus exists in a nebulous space when it comes to his identity. He's the offspring of the worst of mankind and wishes to resist his background, yet he cannot completely participate in the culture he admires and, in the case of his crush on Kiri, adores.
Kiri is a young Na-vi around fourteen years of age. Since she was conceived through an avatar body (a genetically engineered human/Na'vi-hybrid body, designed to serve as a remotely controlled vessel for a human mind) she was born with human-like traits, such as eyebrows and five fingers instead of four.
However, the decision to have Sigourney Weaver play Kiri seemingly links her to Dr. Grace in some fashion. This could mean that Kiri hears Dr. Grace's heartbeat after she dies at the Tree of Souls and unites with the planet's deity, Eywa.
