In James Cameron’s ‘Avatar,’ the main character Jake Sully, for sake of time, leaves the world of man behind and joins the cause of the Na’vi, an alien race (to us, at least) that are fighting off the militant threat to defend their home world. When it comes to leaving his man body behind via neural transformation or some similar process, it can be seen that he is leaving the Leviathan behind. However, I don’t think this is really the case; instead of exiting the Leviathan for good, it seems to me that he has entered a new Leviathan all together; the world of the Na’vi.
In the movie, Sully initially joins the fight for (lack of a better word) corporate greed, and sees how his services reek havoc on the planet. He then gets uplinked into a Na’vi body, lives among the local inhabitants, and has a change of heart, joining their cause. He fights against the machines of man with the beasts of the planet, and it seems as if he has defeated the enemy and has left the Leviathan.
However, by being exposed to the way of the Na’vi, by integrating into their society, by becoming ONE with the Na’vi. When it comes to the Na’vi, they use their ‘ponytails’ to connect with all living things, to conjoin, to link into a collective consciousness. When he becomes a Na’vi, he literally becomes a part of a larger whole, a piece of society that that literally is a part of a larger being. By forsaking his old body and the Leviathan of man, he becomes a part of a new Leviathan of the Na’vi and becomes a warrior to defend his new family.

Great point on Jake leaving a leviathan only to enter another one. Your title points this out too and it combines well with you argument.
You have interestingly addressed two different views. You do this by first describing how it can be seen that Jake Sully has defeated the Leviathan in way, to then explaining how Jake actually transfers into a “new Leviathan” of the Na’avi people. As you point out exiting and joining one Leviathan to another, creates this bigger question of whether there are multiple Leviathans existing among various realms, or rather there is one great Leviathan ruling all realms though interpreted differently among worlds and cultures. Nice analysis!
Your title is great because it presents your ideas well, Jake is not only abandoning his “humanity” but also his home country. While you explore this pretty well, I think you could really dip down by questioning if the concept of a leviathan is good or evil. Does a leviathan have to be good all the time? Can it be bad? Or can it start the way an infection start- benign and if left unignored, festers into a disgusting more harmful version of itself?
I liked this. The point about Jake “Leviathan jumping” from Earths conventions to Na’avi paints a larger image about the definition of the Leviathan and creating a skewed perception of a moral spectrum. But do you think he still abides from his old Leviathan and old conventions he attained from when he was human? How do you think his instilled skills he gained from when he was a Marine and the memories of the tribulations of being handicapped come into play when considering the Leviathan?
