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.
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.
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.
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.
Well, the Jedi might be quite intrigued by Earth's diverse cultures. They could be amazed at how different our beliefs and ways of life are compared to the galaxy far, far away.
A young Earthling who is discovered to be extremely Force - sensitive could be a main character. He or she could be mentored by an old Jedi master and go on a journey to learn about the Force and their place in the Star Wars universe.
One main character could be a military general on Earth. He has extensive combat experience and is tasked with leading the defense against the Star Wars invaders. Another could be a young orphan who discovers he has an uncanny ability to interact with the Force, which makes him a key figure in the fight. And perhaps a Jedi who has been exiled to Earth long ago and now has to step up to help his new home planet.
The Separatist droids would have a harder time adapting. Their programming is mainly for the Star Wars universe battles. But they could be reprogrammed by some Earth scientists or hackers, which could lead to some very unexpected situations, like droids being used for peaceful construction projects instead of war.
Some Star Wars characters might be quite amused by Earth fanfiction. For example, Han Solo would probably find the wild and creative ideas in the fanfiction hilarious. He'd chuckle at the strange interpretations of his character and the out - of - this - galaxy concepts that Earth fans come up with.
Maybe an experienced admiral from the Earth Defense Fleet. She would bring her strategic knowledge to the table when dealing with the complex political and military situations in the Star Wars universe. And she could also form alliances with characters like Leia Organa.
A character could be a Force - sensitive child from the United Earth Empire. He was born with this power but was hidden away on Earth. When the Empire discovers his abilities, they want to use him as a weapon. However, he is befriended by a group of rebels who help him understand the true nature of the Force and fight against the Empire's evil plans.
