A great plot idea is that the fem OC mercenary discovers a hidden map to a long - lost Jedi temple. However, she has to outwit a group of Sith cultists who also want the map. As she travels across different planets in search of the temple, she teams up with a local resistance group. Along the way, she uncovers secrets about her own past that are linked to the Jedi. This would make for an exciting and complex fanfiction plot.
How about a plot where the fem OC mercenary is framed for a crime she didn't commit? She has to clear her name while also dealing with various bounty hunters on her tail. She could seek help from an old acquaintance, a smuggler who has his own reasons for getting involved. Meanwhile, she uncovers a conspiracy within the Galactic Empire that could change the balance of power in the galaxy. This would create a lot of tension and action in the fanfiction.
A common plot idea is the mercenary getting caught in the middle of a galactic power struggle. For example, between the Empire and the Rebellion. They might be hired by one side, but then realize they've been used or that the other side has a more just cause. Another idea is a quest for a valuable artifact. The mercenary could be hired to retrieve it, but face many obstacles and other parties also after it. Or, they could be on a personal vendetta against a powerful crime lord in the Star Wars universe.
Maybe the fem OC is a bounty hunter who gets caught in the middle of the Clone Wars. She is hired by the Republic to track down a Separatist spy, but as she gets closer to finding the spy, she realizes that there are deeper conspiracies at play. The Republic might not be as pure as it seems, and she has to decide which side she really wants to be on.
One common trope is the 'lone wolf' type. She operates alone most of the time, only teaming up when the pay is really good. Another is the 'mysterious past' trope. No one really knows where she came from or who she was before she became a mercenary.
One plot idea could be that the fem OC bounty hunter is hired to capture a rogue Jedi. This sets up an interesting dynamic as she has to use all her skills against someone with the Force. Another idea is that she gets caught in the middle of a power struggle between two crime syndicates. She has to play both sides to stay alive and complete her own mission, which might be to retrieve a valuable artifact. Or she could be on a quest to clear her name after being framed for a crime she didn't commit, all while still taking on bounty hunting jobs to make ends meet.
She could be a clone who rebels against the clone programming. Instead of blindly following orders, she starts to question the morality of the Clone Wars. She might try to find a way to end the war peacefully, even if it means going against her own side. This would create a lot of internal conflict as well as external conflict with her superiors and comrades.
One idea could be a mercenary who is hired by a mysterious Sith Lord to steal a powerful Jedi artifact. The mercenary then has to navigate through various planets, dealing with both Jedi and Sith along the way.
Well, start with her name. It should be something that fits the Star Wars universe. Then, for her personality, you could make her a bit of a loner but with a strong sense of justice deep down. In terms of her role as a mercenary, she could be specialized in retrieving rare artifacts. She might get involved in a plot where she has to steal an ancient Sith relic. In the process, she could cross paths with the likes of Han Solo or Chewbacca, which would add a lot of excitement to the fanfiction.
When creating a fem OC mercenary in Star Wars fanfiction, start with her motives. Is she in it for the money, or does she have a deeper cause like seeking revenge for a wrong done to her family? Her code of ethics is also important. She might not be a typical 'good guy', but she has her own rules. For instance, she never kills unarmed opponents. This makes her a complex and interesting character.
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.

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.
A great plot idea could be that your male OC discovers an ancient Sith artifact that has the power to change the balance of the Force. He then has to decide whether to use it for his own gain or destroy it. Another idea is that he is mistaken for a Jedi and is hunted by the Empire. He has to learn about the Jedi ways quickly to survive. Or, he could be part of a rebellion on a small planet that the Empire has overlooked, but his actions draw the attention of the Emperor.
