Nausicaa takes place on an obscure planet in the Star Wars universe.Commerce with other systems has been basically nonexistent for centuries, possibly because the planet was already mined out and after its ecological collapse, contains nothing of value. Nausicaa herself is Force sensitive, explaining her ability to communicate with the ohmus.
Nausicaa is the far future of the Blue Gender universe.Well, they're both environmentalist stories involving monstrous insects.
- Jossed in the manga, where the insects (& pretty much everything else, including some of the architecture) are revealed to be the result of genetic engineering.
Ashitaka from Princess Mononoke was the first Blue Clad One.Ashitaka wears a blue costume and fights for peace between humanity and nature, just like Nausicaa. He may, in fact, be the origin of the legend of The Blue Clad One. After he saved everyone from The Nightwalker, he was deified by certain Shinto sects; his legend survived to become part of the bizarre mashup of Eastern and Western faiths that formed the native Dorok religion.
- Makes sense, seeing as Ashitaka and San are inverted versions of Nausicaa and
Sam Witwickithe Pedjite prince respectively.

Nausicaa takes place after the other Ghibli filmsExcept Kiki's Delivery Service, which takes place in Howl's Moving Castles alterna-Europe. Going in chronological order, the woods in Princess Mononoke are eventually inhabited by humans, who transform it into My Neighbor Totoros town, which is "modernized" into the Tama New Town/Green Hill of Pom Poko, where Chihiro's family moves to in Spirited Away.
Alternatively, Nausicaa takes place before the other Ghibli films.The Sea of Corruption succeeds in purifying the Earth. Mankind somehow avoids going extinct in the interim, and we figure out how to bio-engineer ourselves back to humanity's original form on our own. (Humans are stubborn.) Things return to normal except for remnants of previous civilizations: ancient weapons such as The Castle in the Sky; bioengineered creatures like Totoro, the talking animals, Yubaba, and her clients; and descendants of Nausicaa and Selm's children who have inherited their superhuman abilities, such as Howl and Kiki.
Similarly, Nausicaa is the direct descendant of Ghibli's leading ladies.In rough order, the genealogy would be San (Princess Mononoke), Fio (Porco Rosso), Kiki, Satsuki (My Neighbor Totoro), Taeko (Only Yesterday), Rikako (I Can Hear the Sea), Shizuku (Whisper of the Heart), Chihiro (Spirited Away), the unnamed angel girl (On Your Mark), and Sheeta (Castle in the Sky). Tales of Earthsea and Howl's Moving Castle, being adapted works of Western authors, don't fit into the timeline/genealogy. All the girls have defining characteristics that Nausicaa displays; Fierce independence, practicality, nature loving, deep loyalty and commitment, insatiable wanderlust and a love of flight, to name a few. This genealogy can also serve as a timeline for the films, although it gets a little fuzzy with the ones that take place in modern Japan. They aren't necessarily directly related, but their bloodlines get passed down to the end. The world gets more and more industrialized, leading to the scenario in On Your Mark, causing people to take to the skies to get away from the damage being done to the planet (some of the airships in Castle in the Sky's opening sequence bear a striking resemblance to the airships in Nausicaa).
Alternately, Nausicaa is the reincarnation of Chibli's leading ladiesReincarnation seems more likely than descent to explain similar personality characteristics
The God Warriors weren't always giant radioactive cyborgs.In the final volume of the manga, it's more or less confirmed that the God Warriors weren't originally intended as weapons, but rather were an attempt at some kind of robotocracy. Why, then, would their creators give them bodies capable of such indiscriminate destruction? Answer: They didn't always have those bodies. They were originally just supercomputers, but they judged humanity to be beyond saving and created new bodies for themselves to wipe out civilization.
Alternately, the God Warriors were created to save the environment and, in their creators' opinion succeeded.All the God Warriors' rhetoric about judging mankind was simply a falsehood programmed into their AI by their creators to make sure they played into their scheme. Their role was planned all along. The scientists calculated that the environmental impact of vaporizing all the developed nations on Earth with radiological weapons was less than that of allowing them to survive & continue polluting; the rest is history.
The altered humans who populate the world of Nausicaa are much smaller than True-men.Think about it: the only time we seem them interact with people from before the 7 Days of Fire is through holograms, which aren't necessarily to scale. It would explain how Nausicaa is able to ride around on such a comparatively tiny aircraft, & how the insects appear so huge in spite of the Square-Cube Law.
- There have been some reasonably successful attempts to recreate Nausicaa's mehve glider in real life. There are power and stability problems, but lift doesn't seem to be an issue. The Square-Cube Law remains a big issue, though.
- The insects probably have very different internal body-structure than their Real Life counterparts, considering that they are artificial life-forms.
Tolas used to be Hill Valley.And the Emperor is descended from Helga. Just look at the guy.
Captain Picard is Lord Yupa.Captain Picard was sucked into some space warp hole or something, and became Lord Yupa. Makes total sense since they are both swordsman. Also they are voiced by the greatest actor to ever lived, Patrick Stewart.
Nausicaa is the past of MushishiSince Nausicaa could be the past of Mononoke... The insects and fungus mutated into mushi after their task of purifying the earth's toxins was complete. No one remembers the Ohmu or fungi because the purification process took a lot longer then expected. The Koki or sake of life is a band of mildly irradiated water that flows deep beneath the ground in the purified/petrified forest.
Nausicaa is the past of the Bugg Planet in Space UsagiThe human race was taken over by sapient animals who live in harmony with the bug(g)s.
- Alternatively: humans bioengineered themselves to look like sapient animals so that they could live in harmony with the world.
Nausicaa is in the same universe as Xam'd: Lost Memories.Both settings have aircraft that couldn't stay aloft by known aerodynamics laws and bioweapons causing trouble. Xam'd could be the past and the research on Xam'd eventually leads to the God Warriors, or Xam'd could be the future, where leftovers from the Nausicaa time period still cause trouble, perhaps the Hiruken Emperor was a keeper of information.
Nausicaa is the sequel to the Ender's Game series . Ender brought the last Bugger Queen to another planet, which was colonized by humans much later.Castle in the Sky are clearly powered by Unobtainium, and the bioluminescent fauna and flora in the underground forests later took over the planet. That would explain why the Na'vi look so much like humans as well, and the lowered gravity of Pandora explains how the Mehve glider and the huge insects can work.
- In Avatar, Pandora is a moon in Polyphemus, a planet in the Alpha Centauri System. Avatar takes place in 2154, and it is canon that humans intentionally travelled to Pandora as it was originally presented to mine the unobtanium.  More likely, humans would kill off the Na'vi and the Avatars - one of whom is remembered as the blue-clad warrior. Humans then terraform the planet: they alter the atmosphere to make it safe for them to breathe, create new life forms like the the fox-squirrels and the horseclaws, and use unobtanium to create the floating castle as a station in the Hallelujah Mountains. The crystal in the castle - called volucite in Japanese, and aetherium in English - is a shard of unobtanium, although it is unknown how the name got changed from unobtanium, or why the castle's architecture doesn't match up with the rest of human architecture on Pandora. Then come the Seven Days of Fire, and one thousand years later during Nausicäa's time, the Toxic Jungle is Eywa's way of recovering the land and reverting it back to Pandora's original state. The insects, especially the Ohmue, are sensitive to Eywa without needing a neural interface - similar to how in Avatar the sturmbeests come out of the forest in the final battle and crush the AMP suits. Nausicäa is also sensitive to Eywa. In the manga, the prophecy says she will "forge anew our ties with the lost land": this may mean either Pandora as it was before the Seven Days of Fire, or the distant Earth. There is also a crypt storing knowledge of humanity's history, which may have been intended to reconnect Pandora with Earth in some way.
The Ohmus and other psychics are the reason nobody uses radios anymore.Their telepathic Hive Mind doesn't work on some mystical New Age-y principles, they're some kind of biotechnological radios, possibly working by arranging minerals within the body strategically into specialized diode organs. Those spikes all over the Ohmus' bodies may actually be a kind of biomechanical radio antennae. The reason nobody ever finds any radios or other communication devices among the ruins is because the ancients had long abandoned them with the advent of bio-engineered "telepathy" and even if somebody got one working again it would be useless because the Ohmue hive mind and other psychic communications would be constantly drowning everything else out with interference.
"Nasicaä" and "The Castle in the Sky" take place at the same time or close to each other.So before you protest hear me out. This Theorie of mine actually fuses multiple Ghibli theories together.Those are, the shared Ghibli universe, and the Nasicaä takes place on Mars theories.So one thing in Nasicaä of the valley of the winds really got me thinking and that was the Star Ship. That is a oddly specific name. Now air ships are pretty common in that world, but that giant wreck that seems to have been rotting for centuries has this special name. And that was when it clicked. The hints of technology we get from the story indicate an incredible advanced level. Biomanipulation of the highest tier and powerful energy weapons are only two. A civilisation that advanced would pretty sure able to at least travel between planets if not even traverse interstellar distances.So how das this connect to The Castle in the Sky? Well for one used technology if a little bit different is still nearly exactly the same. Giant air ships are a common occurrence but we also see indication of a long gone civilisation. And this civilisation utilises incredible advanced technologies including gravity manipulation and extremely powerful energy weapons that do seem to be pretty familiar.Two civilisations with somewhat similar technologies that were destroyed in the far past. The worlds have similar technologies used by the still living humans and even share some animals.And that is how I came to the conclusion that those both worlds are two planets of a passed interplanetary or even interstellar civilisation that destroyed itself in a apocalyptic war.
