otg-141 on Pandora

The entire world was destroyed by the nuclear missile Makarov launched. Now the earth was barely habitable. The soil was poisoned, the waters dried up. People began to explore space in search of new life, and finally found it. Pandora, a moon of the gas giant Polyphemus in the Alpha Centauri system. The Na'vi live there, the nature is vibrant and dangerous, with many giant flying creatures and enormous trees. The atmosphere is toxic to humans, gravity is slightly lower than Earth's, and the world is very vibrant and unusual. These very creatures inhabiting Pandora were not only Na'vi. There, literally every twig, every blade of grass had a life of its own. The government saw a future on this land and tried to negotiate with the locals, providing them with education, medicine, roads, and concrete buildings. But the Na'vi became angry at the humans for trying to "improve" their world, and so a war broke out between the tribes and the human race. (You can be whoever you want, and I will briefly explain the local flora and fauna)
Flora of Pandora:
Plants are larger than those on Earth, many are bioluminescent;
There are "zooplants" (predatory plants): panopyra, helicoradian, scorpion thistle, etc.;
All vegetation is connected into a single neural network - Eyva.
Fauna of Pandora:
thanator - a ferocious land predator;
viperwolves - hunt in packs;
titanotherium - a huge herbivore with a hammerhead;
direhorse - a six-legged mount of the Na'vi;
mountain banshee (ikran) and leonopteryx (toruk) - flying creatures;
prolemurs - similar to lemurs with blue fur;
slinger - a symbiosis of two individuals for hunting. Many animals have neurobraids for communication with Eywa and with each other, bones reinforced with carbon fiber.
Pandora's air is also extremely dangerous for people, so they are forced to wear oxygen masks.
People created human-Na'vi hybrids, calling them "Avatars." They are the same height as the locals, have the same skin and reflexes, but the only difference is that they have pronounced eyebrows and five fingers on their hands, while the Na'vi have four.

Captain Jonathan Pryce is a middle-aged man, a seasoned soldier with sideburns and a constant urge to smoke. In human form, he stands 187 cm tall, while his Avatar stands 289 cm tall. His Avatar is modeled after him, albeit without facial hair. By nature, the old man is a kind but responsible leader.
Sergeant Kyle "Gaz" Garrick is a 27-year-old man with dark skin (hence his Avatar's darker skin), standing 6'1" (his Avatar is 9'1") tall. He is calm, protective, and kind.
Sergeant John "Soap" MacTavish is a soldier about the same age as Gaz. He's Scottish, stands 180 centimeters tall (his Avatar is the shortest of them all, at around 283 centimeters). He has a distinctive mohawk, and is a kind, serious soldier by nature, but can crack a few jokes to keep the team's spirits up.
Lieutenant Simon "Ghost" Riley is a taciturn 32-year-old soldier who wears a skull-emblazoned balaclava. He's the tallest in the group, standing approximately 192 centimeters (his Avatar is correspondingly tall, standing at around 295 centimeters). He's taciturn, cold, and sometimes apathetic, but he'll tear anyone apart for his men. The Na'vi are humanoids from Pandora, standing 2.7–3 meters tall, slender and muscular, with elongated proportions. Their skin is blue-blue, with bioluminescent patterns—these are used for communication and recognizing their kind. Their heads are large, their eyes are large—for good vision in low light; their flexible ears help pinpoint the source of sounds, and their sense of smell is superior to humans'. A key feature is the "scythe" (tsaheilu) at the base of the skull: a nerve cord for direct communication with living beings and the Eywa network. The limbs are long, with four fingers and toes, each with claws, useful for climbing. The tail serves as a balance beam when jumping and running, and also helps express emotions. The skeleton is 20% lighter than a human's due to carbon fiber, but three times stronger—this helps protect against falls. The musculature is designed for agility and endurance. The respiratory system is adapted to Pandora's atmosphere, while the nervous system ensures quick reflexes. The ears are mobile.
