No, it's not a common element in official Star Wars canon. But in fanfiction, it can be whatever the author wants it to be. So it might be common in some specific fanfics but not across the board.
One plot idea could be that your SI OC is a young Force - sensitive being discovered by the Jedi Order, but they have a connection to an ancient Sith prophecy. The Jedi must decide whether to train them or fear their potential for darkness. Another idea is that your OC is a bounty hunter who gets caught in the middle of a power struggle between the Hutts and a new criminal syndicate. They have to use their wits and skills to survive and maybe even tip the balance of power.
One popular theme is the 'what - if' scenarios. For example, what if Anakin Skywalker had not turned to the Dark Side? Another common theme is exploring the backstories of minor characters, like how a stormtrooper became part of the Empire. There are also a lot of fanfictions that focus on romantic relationships between different Star Wars characters, such as Rey and Kylo Ren.
One great Star Wars SI (Self - Insert) fanfiction is 'A New Hope in a Galaxy Far, Far Away'. It has an interesting take on a modern - day person being inserted into the classic Star Wars universe. The protagonist's struggle to adapt to the different technology and culture while trying to influence the events in a positive way makes it engaging.
There's also 'Galactic Adventures of a SI'. This fanfic is amazing as it combines elements from different eras of Star Wars. The SI character has to navigate the complex politics and power struggles within the galaxy. It's full of action - packed scenes and the author does a wonderful job of creating new and exciting storylines while still respecting the Star Wars lore.
In Star Wars fanfiction, 'Si' could potentially be a character's name, a made - up planet, or an abbreviation for something specific within the fan - created story. It really depends on the context of the particular fanfiction.
First, think about the Star Wars universe's different species, cultures, and planets. For example, if your OC is from Tatooine, they might be tough and resourceful like the native Tuskens. Then, give them a unique backstory. Maybe they were orphaned during a Sith raid and have a vendetta against the dark side. Also, consider their skills. It could be something like exceptional piloting skills or a natural ability with the Force that sets them apart.
You can find Star Wars fanfiction on websites like FanFiction.net and Archive of Our Own (AO3). These platforms have a vast collection of fan - created stories set in the Star Wars universe.
One popular 'Star Wars Si Fanfiction' story could be about a self - inserted character who becomes a Jedi apprentice. They might go on adventures with well - known characters like Luke Skywalker, learning the ways of the Force and facing off against the Sith. Another could involve a character inserted into the Clone Wars era, perhaps fighting alongside the clones and dealing with the political intrigue of the Republic.
One common theme is self - discovery. The male self - inserted characters often start off not knowing their place in the Star Wars universe and then gradually figure out their strengths and purpose. For example, they might discover a hidden talent for using the Force in an unusual way.
