Well, one possibility is that the technology from Star Wars would start to merge with Earth's. Droids could become common household items, helping with daily chores. And starships might be parked in our skies, changing the whole dynamic of Earth's society as people try to figure out how to interact with these new, alien things.
A 'Star Wars Invades Earth' fanfiction could involve characters from Star Wars recruiting Earthlings to fight in their galactic wars. Earth soldiers might be trained in the ways of the Force, and they could bring their own unique combat skills to the mix. This could lead to a whole new alliance in the Star Wars universe, with Earth becoming an important part of the fight against the dark side.
In such a fanfic, there could be epic battles. The Empire's advanced weaponry like the Death Star might be used against Earth's defenses. Maybe the Rebel Alliance would also get involved, teaming up with Earth's forces to fight the common enemy.
Luke Skywalker could be one of the main characters. He might come to Earth to spread the teachings of the Jedi. Another could be Darth Vader, if he somehow survived and ended up on Earth, causing chaos and trying to rule over the planet.
In this kind of fanfiction, the Empire's arrival on Earth would change everything. They might be interested in Earth's biological diversity for their own experiments. The Jedi, if they somehow got involved, could either help Earth or have their own agenda. Also, the political situation on Earth would be turned upside down. Nations might have to unite against the common threat of the Empire. And there could be interesting character interactions, like an Earthling befriending a stormtrooper who starts to question the Empire's ways.
It could be an ordinary human on Earth who rises to become a hero against the Empire. Maybe a scientist who figures out a way to counter the Empire's force powers.
In a Star Wars droid on Earth fanfiction, the droid's arrival would be a game - changer. It could communicate in ways we don't understand at first. If it was a protocol droid like C - 3PO, it might try to establish diplomatic relations, which would be really strange considering we don't have other planets to have diplomacy with in the same sense. It could also introduce new concepts of engineering and mechanics that could revolutionize our technology, but it would also face the challenge of being an alien entity in a world that might not be ready for it.
Well, if Star Wars goes to war with Earth in fanfiction, the political aspects would be very interesting. The Galactic Empire or the New Republic would have their own agendas. Earth's various governments would need to unite quickly, which could be a problem in itself. There would be a race to see who could adapt to the other's technology and warfare style faster. And what about the Ewoks? Could Earth learn from their simple but effective tactics against the Empire?
If the Star Wars Empire invaded Earth, it would be chaos. Their advanced weaponry like blasters and starships would overpower our current defenses. Earth's militaries would struggle to fight against stormtroopers and AT - AT walkers. Maybe some groups would try to form a resistance, just like in the Star Wars movies.
It could be a source of new allies. Earth has a large population, and if the people of Earth were to be introduced to the Star Wars universe, some of them might be Force - sensitive or have skills that could be useful. They could join the Rebellion or the Empire, depending on their motives. For example, Earth's military strategies and technologies could be adapted to the Star Wars setting. The use of Earth - based guerilla warfare tactics could give the Rebels an edge in some battles.
Well, one possible plot could be that the Sith Lords, seeking new territory and resources, target Earth. They send their fleets and powerful dark side warriors. The Earth's militaries initially try to fight back using conventional weapons but quickly realize they're outmatched. Meanwhile, a group of Earthlings discovers ancient Jedi teachings and starts to develop Force - like abilities to resist the invasion.
In such a fanfiction, perhaps the Jedi could encounter alien species from UFOs. They might team up to fight a common enemy, like the Sith who are trying to harness the advanced technology of the UFOs for evil purposes.
