In one scene in Avatar, Jake, played by Sam Worthington, after just arriving in Pandora he goes on his first mission on the planet, through the jungle and wilderness. He is getting used to his Avatar and is separated from the group of Weaver's character, Dr. Grace Augustine, and More's character, Norm. This signifies that Jake is different from the other two, and is separated from them. He also finds himself isolated from the other Avatars, which suggests that he is somehow chosen, unique, and special. He is also carrying a gun - a signifier that represents the military aspect of Jake, and his upbringing, experience, and how he acts in the situations he finds himself in. He finds himself amongst a bunch of plants that spiral, and pop and curl up when touched. The plants suggest that Pandora is a generally hidden and closed off place, that is hidden and mysterious to outsiders. But when Jake touches the plants he finds a general pleasure in the movement of the plants, but they end up revealing a large herd of hammer-head-shark-esque rhinos, dangerous animals that defend their territory - a precursor to the Na'vi's hesitation of outsiders because of the dangers that come with unknown entities, such as Jake in Pandora. Jake reacts by pointing his gun at the creature, what he has been trained to do all his life, yet Weaver, who has an extensive knowledge of the planet, tells him the bullets will be useless against the armored skin of the rhinos. This suggests that Jake is ignorant of the world of Pandora and that he still is, for all intensive purposes, still human and carries the knowledge of humans, of Earth. This unearthing, from the plants, of something dangerous, the rhinos, signifies that humans, which Jake is very much a part of still despite being in an Avatar, do not know what they are getting in to, and that they will find a danger and violence on Pandora, which in this case overpowers them. Basically, the mercenaries, the humans, will lose eventually. But the plot thickens as a large, black cat-like creature looms above Jake, signifying the obvious power and killing prowess that the cat wields over Jake. This event reiterates the power and danger hidden amongst Pandora, and thus, the Na'vi. This cat, which hunts down Jake after this scene, wields complete power over the tiny bodies of the three Avatars. Overall, this scene acts as a precursor for what will become of the humans on Pandora in their mission to obtain unobtainium. In addition, its signifiers continue to portray Jake as a special person, whom will be isolated (being alone) and wield power (has a gun, surviving the attack of the rhino and the cat, etc.). The Na'vi are the eventual, unknown danger looming in the futures of the humans, who do not fully understand what is ahead of them, despite the pleasures they find on Pandora (unobtainium).
