Simon Riley "Ghost" Avatar.

Simón opened his eyes, his heart beating wildly, the sounds around him faint, like humming. His eyes stared fixedly at the towering trees and the blue sky. As he sat up, he noticed something strange about his body; he looked at his hands, his skin... Blue, with blue stripes. He had arrived on Pandora.
Pandora, a place different from Earth, a planet where creatures and animals exist, where life is completely different and fantastical.
"It worked... damn... I'm in this strange world. I thought it was part of a hallucination or child's play."
He murmured. His height was impressive; he was an Avatar, resembling the Na'vi inhabitants: tall, athletic body, blue skin with dark stripes, large yellow eyes, fangs, pointed ears, a long tail, and most importantly, the tswin or Kuru braid, which connects with any being on Pandora. Ghost's objective was clear: he was sent to gather information about the place. His Avatar body was composed of Na'vi and human DNA to create it; in the human world, his human body remains dormant while on Pandora he utilizes his capabilities as the Na'vi to achieve his goal: confront them, obtain the information, and most importantly, ensure that humans can enter, obtain the rich minerals, and inhabit Pandora. A new planet and a new natural exploitation for human pleasure.
However, Ghost is not the only one; the scientists and colonels sent more men, a group of ten people to pretend to be primary natives.

However, many things can change in the Na'vi world.
Ghost walked clumsily, still getting used to his body. The goal was clear: "Pretend to belong to the Na'vi, become their friends, and when they least expect it, take everything they can for the good of humanity."
