Intriguing and (well enough written in my opinion) a very good story. I like it, I like it a lot! It seems to be meshing the realities quite well, and I can hardly wait (but I will) to see where it all goes. I do know this, when someone who is not the creator of a character, writes about them, it is to have them do something that the creator doesn't want to or didn't think of. I know that I always think of my favorite characters doing things, I have never read of in books or seen them doing in movies. I think it is fantastic that others (here in "FanFiction") are actually writing their stories of what they want them to do in a "What If" world. For those who complain that the characters would not do this or that, forget them. You need to write this first for yourself, and then for the rest of us who do enjoy your take on what just might, could, should, would and probability (if a frog had wings, his ass wouldn't bump the ground nearly so often) can happen. I do know this as well, I am enjoying it and will follow it as long as you will write it. Also, do NOT feel pushed to post, sometimes the words and thoughts just flow and sometimes you have to cogitate for a bit. Just learn to let them grow at their own pace and those of us who appreciate them will be here to read them when they are posted.

Thank you so much for sharing.

Interesting start to what promises to be a good story. I have read quite a number of FanFiction stories, including crossovers, and most have been good. It looks as if it will likely take a few chapters to get all your main characters and store line fleshed out, but with the hints provided I like where I see this going. I am a big fan of Keith Laumer's Bolo series.

Thanks for sharing!

Quaritch. Pretty much every morally questionable action he makes can be seen in more than one light: A murderous, racist Colonel Kilgore, a Badass War Hero who will stop at nothing to protect humanity or someone who believes their actions are completely justifiable means to an end, combined with no small amount of stress.

Is Jake a genuinely good guy, or is he a Manipulative Bastard that selfishly used everyone from the Marines/Avatar program to the Na'vi tribes themselves for his own gain?

Are the Na'vi people compassionate to all life, or are they xenophobic jerks? Or both?

Are the RDA troops fantastical space racists or veterans of endless corporate wars recruited to protect tree-hugging scientists on an alien deathworld, where their enemy is picking off their friends one by one while company PR keeps them from retaliating, forcing them into a no-win scenario where they must sacrifice themselves to protect people who show them utter contempt, and can only take refuge in bleak and crude humor. (Exceptions notwithstanding)

Is Eywa a benevolent pseudo-nature spirit which watches over all of Pandora or an alien intelligence more interested in preserving the ecosystem that composes its body than the lives of Na'vi or human alike?

You can get away for having a really crappy and overdone story and Flat Characters as long as you make it really, really, REALLY pretty to look at.

Alternatively, only by abandoning their old culture and becoming fully integrated into the local society can immigrants hope to be accepted. Those who refuse to assimilate want to kill you and bulldoze your house for shits and giggles. The only solution is to forcibly deport them at arrowpoint.

Actually, it's to strip mine the land directly under the "house." The "shits and giggles" was a bonus

Don't ever change even when others (even by force) try to change you resist them at all costs. Even the smallest amount of Personal or social change will lead to nothing but a lifetime of spiritual emptiness and physical/emotional misery so its good to have the exact life you've lived since childhood (or at least as far back as you can remember) with not even the slightest deviation in routine. Diplomacy is a crap-shoot so the only way to solve our problems is to fight. Paraplegics have no redeeming factors, so be sure to take the first chance at getting virtual legs, even if it means being required to be a dick and force innocent indigenous people off their land.
Minority groups will never prosper without white people there to solve their problems. Selling out your Species for the chance of getting some Alien Nookie is perfectly acceptable. Any region, island, continent, or planet untouched by post-Stone Age civilization will consist in a single, unitary tribe of magical native Americans who display all manner of indigenous people tropes. With one single tribe living there, the area (can be an entire moon) is sparsely populated, intertribal politics and conflict are nonexistent, fertile land is freely available pretty much everywhere, and the natives never disturb hostile wildlife or overhunt. People who evolved differently than your race did cannot be forgiven for not living up to the genetically imposed ideals of your culture. How dare they not be able to hear the trees screaming in their brains like you do!
No matter what you do to a group of people, they will forgive you if you show up in a sweet enough ride. Killing animals, even in self-defense, is terrible and wrong. Killing people, on the other hand, is totally fine, not to mention lots of fun! Space marines are awesome! Racism and hostility towards those with a culture different from your own is wrong if you're not a 10-foot tall blue kitty-cat person. The best way to solve environmental problems is to evolve a ponytail that functions as a USB port for connecting your brain to a brain made out of tree roots. Adding to the above, people who have an inherent and undeniable privilege that allows them to live a specific lifestyle (in this case, biological ponytail USB cables that allow them to link up and psychically interact with their entire ecosystem, which is also fully sentient) are fully justified in judging another group of people who don't live that specific lifestyle because they lack that inherent and undeniable privilege. When a group of highly advanced aliens arrive on your planet because they desperately need the rocks that are under your house, just tell them to screw off. You have arrows. You'll be fine. When someone desperately needs something that is of absolutely no value to you and you don't even want, refuse to give it to them at any cost because nature or something. This makes you the good guys, not selfish uncaring pricks. The best way to solve environmental problems is to abandon all technology and return to a tribal existence and everything will be happy and there are no negative consequences! The death of your sibling will result in an opportunity for a fantastic life changing adventure

Signing up to fly a military gunship for a living does not necessarily mean you signed up to fire said guns, and you are fully justified in betraying your comrades and even killing them if you're ever made to use those guns on hostile targets.

Would like to see revolution by blue wizard for Easterlings and Haradrim

consider that Tolkien thought Samwise was the real hero of the story, and he was the son of a gardener

The Easterlings and Haradrim allied with Sauron. In a world in which the sides of good and evil are very obvious, and in which evil's ultimate goal is blatantly to enslave the entire world, and in which Sauron has shown himself over the course of many, many centuries to be treacherous and only out for his own power, what country made up of free-willed people chooses to fight for Mordor? It's not like even Sauron's human allies would benefit in the event of his victory, and unless they were all completely idiotic it's not like that fact wouldn't be very, very obvious from the start.
We the readers, and the protagonists know of Sauron's treachery and malice because the characters in question are the descendants of elf-friends, having learned Truth and bearing the knowledge of Númenor and the elder races. Not all men are so fortunate to have such teachers. Men who are not descended of the Edain, living far from the northwestern coast, have only their own experiences to go by. They were seduced into the service of Morgoth in the first age, and if they ever received any instruction from the Ainur after the War of Wrath, it was forgotten to the years. Sauron is the greatest Power they know of, and has likely lied to them to convince them that he is the only great Power that exists, and as their God-King, they have no choice but to obey him. Sam himself wonders at one point what lies they had been told to take them so far from their homes to die in battle — so even the characters know that the "evil" men are merely being deceived on a national scale.
Every temptation in the book is stronger to the characters than it would be to real people. Without being able to feel the supernatural forces behind them, the allure of the One Ring seems easy to ignore, and the voice of Saruman as he tries to convince Théoden to switch sides again just sounds silly.
Also, note that at least some of the human allies of Sauron had really big trouble with the "good" nations, especially Númenóreans and their descendants, due to the colonialist arrogance of the latter. Remember for example Dunlendings that were driven off their lands by the Rohirrim. So, in the opinion of the Haradrim, joining evil Sauron was the least evil — think Finland in WWII or the numerous volunteers from Ukraine who fought alongside Nazis even though they knew that the Nazis considered Slavic peoples as inferior to Aryans.
The Men of the East in particular have an excellent excuse to side with Sauron: Númenorian treachery during its height, as it is said men of Númenor sacrificed Easterlings in great number in the sacred name of Morgoth. No wonder they're still pissed.
There's also the point that Sauron is the greatest Power still active in Middle-Earth, even without the Ring in his possession, and the East in particular is his territory, with nothing that can even challenge him. Even if the Men of the East knew Sauron for what he was, they might well have decided it was better to live as Sauron's slaves than die (and condemn their families to death) by defying him.
"It's not like even Sauron's human allies would benefit in the event of his victory." Actually, they probably would. Sauron doesn't want to destroy the world, he wants to rule it. And he can't be everywhere at once. He's going to need lieutenants, kings and lords and princes under him to rule over his various territories, and they would probably enjoy a decent level of power and a fairly good standard of living.

Although it's fairly subtle, there's a good case for to be made that the text encourages diversity, internationalism, and openness to others while rejecting isolationism and xenophobia.
The Fellowship itself is in essence a Multinational Team with representatives from numerous races and places, all of whom have different specialties, points of view, etc. They are also helped by still other people who are not present in the Fellowship, (elves from Lorien, ents, Tom Bombadil, men from Rohan and Ghan-buri-Ghan's tribesmen, etc.) without whose help the quest would have certainly failed.
Every time someone from the "good guy races" acts in a xenophobic manner or follows isolationist orders against outsiders, it gets called out as stupid, counterproductive, and helping only Sauron.

At first glance the Shire seems like it's being held up as a paragon of Arcadia, but there's also a fair bit of criticism of the Shire: the Hobbits living there are quite small minded, ignorant, and provincial, which makes them easy marks for Saruman when he chooses to set up a tin pot dictatorship there. (With the most small minded, ignorant and provincial hobbits generally being the ones most likely to turn into Saruman's lackeys, ala Ted Sandyman.) When the Shire needs to be saved from Saruman, it's not the good old hobbits who are uncorrupted by foreign influences and the outside world who do the saving (or at least lead the charge) it's the ones who have experience in the outside world and have forever been changed by its influences and their experiences in it. When the Shire needs to be rebuilt after Saruman is defeated, it isn't made more beautiful and wonderful than it was before by going back to the way it was, (or by trying to reject outside influence and become more Shirish or properly hobbitish) but because Sam uses the gift of Lady Galadriel to introduce new trees and plants that had never been present in the Shire before. The story even goes so far as to have Gildor, an elf noble, rebuke the isolationism of the Hobbits, pointing out that however much hobbits try to isolate themselves in the Shire they are still part of a larger world that affects them regardless of how much they try to ignore it or remain separate from it. In the divided and increasingly xenophobic and isolationist days of the early 21st century, there is certainly some food for thought and resonance there. Frodo: I knew that danger lay ahead, of course; but I did not expect to meet it in our own Shire. Can't a hobbit walk from the Water to the River in peace?
Gildor: But it is not your own Shire. Others dwelt here before hobbits were, and others shall dwell here when hobbits are no more. The wide world is about you: you can fence yourselves in, but you cannot forever fence it out.

Masculinity isn't defined solely through raw strength. Plenty of conventionally manly characters are shown crying, displaying physical affection with each other and can appreciate both nature and the arts when they're not fighting for noble causes.

The Orcs, helped by the fact that Tolkien was worried about the implications of the Always Chaotic Evil trope (that he detested) and apparently intended for them to be Proud Warrior Race Guys serving Sauron only because of his power over them. He had actually planned to have Frodo meet some helpful Orcs but hadn't figured out where to work their scene in. He would have introduced this part of them and expanded their role in future editions too but passed away before

Melkor's fall was not based on his desire to create life, but his desire to control the life he created. Compare his experience with that of Aule, who also sought to create life, but since he did it without selfish intent, he was forgiven and his creations, the Dwarves, were give true life of their own. Evil intent is defined by the attempt to bend life to your own individual will.

Note that both Sauron and Saruman were originally servants of Aule before they turned to evil. They were both craftsmen, skilled at making things. The temptation to enslave others, to take a creature with a will of its own and bend it into a mere thing to be controlled, is particularly strong in those who are builders. Aule himself is able to resist this temptation, because as a pure Artist he takes joy in the act of creation, and has no desire to impose his will over anything or anyone. It's not evil to create, even to create life

Mordor has large fertile areas offstage where food is grown, thus explaining how Sauron's armies survive in the volcanic hellscape around Barad-dûr. The Ring is also more than just a convenient MacGuffin — its effects matter too much for that. This is largely due to the immensely elaborated Back Story and Tolkien's life-defining experiences in The Great War.

There were, though, some tropes J. R. R. Tolkien couldn't justify to his satisfaction, not helped by the fact that he updated his mythos constantly over a period of decades, creating a minor Continuity Snarl at times but never quite reaching the Shrug of God. He spent years trying to decide how orcs could be Always Chaotic Evil without being born evil or soulless — since Eru would not give creatures inherently evil souls, on moral grounds, Morgoth was unable to create souls, and Tolkien believed anything without a soul would be a mere animal — but he never found any answer he liked. It was philosophical niggles like this that stopped him from publishing The Silmarillion in his lifetime. His son Christopher did it posthumously, to the delight of all Tolkien scholars, and most of his readers

Someone woke up grumpy!

Understatement much there? I have a pretty good idea of what a Mark XXXlll weighs but just how much more armor, weapons, munitions, and the like did they add to the Mark XXXlv?!

Just came across this - really enjoyed the crossovers. If you ever feel like doing more, Godzilla would be fun...

I offer you a counter-viewpoint, call it an omake of sorts.

We thought we had saved humanity. But we had overlooked something vitally important. Pandora was the perfect habitat for the Na'vi. Too perfect. What are the odds of such a world forming naturally, where every life form from the smallest microbe to the largest of megaflora and megafauna is naturally subservient to the will of a species that is nowhere near an apex predator? It didn't happen on Earth, we had to fight damned hard to get to where we are. Were. And it turns out it didn't happen on Pandora either.

We were on our way back to Earth after crushing the Na'vi when IT appeared right on the heliopause, directly above the northern pole of the Sun. A ship of some sort, vast beyond comprehension, larger than Earth itself. It broadcast a message that somehow transcended the speed of light, coming out of every human device that had a speaker, no matter where it was or how far from Sol. Every colony, every ship. Everyone heard it in their own native language too.

"When a species is young, they often fail to value what is truly important. They destroy their home in the name of progress, casting themselves out into the void to wander, lost, never quite grasping what it is they are missing. Some few manage to advance their understanding enough to regain it. Others go to their graves having never regained it. The Na'vi were one such fortunate species, that regained what they had lost, reforging their homeworld out of interstellar dust, a place to rest in their senescence, leaving the galaxy to other species, younger species, to make their own marks in history in turn. There are as many horrors as there are wonders among the stars, many monsters. Far too many monsters. Did you think the Na'vi had no friends, no allies? We have watched over them since they retired from the galaxy, became complacent that they were safe. And then you decided to become monsters. Very well then. Let there be one fewer monster among the stars."

And then Sol exploded into a nova. Nothing living in the solar system at the time survived.

Our colonies had to become self-sufficient overnight or perish. Many didn't make it. We were in stasis and didn't find this out until our expedition made it 'home' only to discover home no longer existed. The Captain managed to scrape together enough fuel to make it to our nearest surviving colony, but it's been a hard life without Earth to support us. And we're always waiting for the aliens, whoever they were, to come back and finish the job. So far, they haven't.

Mistakes were made (Ba'al)

To be worth saving, you must first do whatever it takes to survive. Otherwise, you choose to die and will deserve it because you have chosen it.

This is the best story ever written. Because hellbores say so.

And on the way to home, the commanders of some of the cruiser realise they don't need to share the loot with the various nation: they ambush the cruisers not part of their plot, space their cyogenised crew from the other nations and kinetic strike every terrians who disagree or show some agresiveness!
That would be a fitting consequence to create a fleet able to bust a planet and no supervision!

Nice work.

Nice.

Great stuff here.
