A Mandalorian warrior could also work well. Mandalorians have a strong sense of honor. A Mandalorian could be initially sent to hunt Vaylin but end up falling in love with her. Their relationship would be a clash of cultures, with the Mandalorian's code of honor against Vaylin's Sith upbringing, making for a very dynamic and interesting romance.
A Force - sensitive outcast would be a great choice. This character is not bound by the rules of the Jedi or the Sith. They meet Vaylin and, through their unique perspective on the Force, show her a different way of living. Their relationship could be about discovery and breaking free from the constraints of their respective backgrounds.
Obviously, Vaylin is a main character in these fanfictions. Often, other characters like Valkorion, her father, also play important roles. And sometimes, characters from the Jedi Order may appear to interact with Vaylin, such as a young Jedi Knight who might try to sway her towards the light side.
One great 'Star Wars Vaylin' fanfiction is 'The Redemption of Vaylin'. It explores her character in a different light, showing her struggle against the dark side. Another one could be 'Vaylin's Journey' which focuses on her adventures outside the main plot of the Star Wars story. There's also 'Vaylin and the Lost Jedi' that creates an interesting scenario where she interacts with a Jedi who tries to turn her to the light side.
Legolas and Han Solo could be an interesting combination. Legolas with his archery skills and grace, and Han Solo with his roguish charm and piloting abilities. They could get into all sorts of adventures together, whether it's fighting orcs in Middle - earth or escaping the Empire in the Star Wars galaxy.
One idea could be a story where a young Jedi falls in love with Vaylin. They meet during a mission on a neutral planet. At first, they are enemies, but as they interact more, they start to see the good in each other. The Jedi tries to help Vaylin break free from the dark side, and through their love, Vaylin begins to question her loyalty to the Sith.
One popular Star Wars Vaylin fanfiction might be 'Vaylin's Redemption' which could explore her character in a new light. It might show her breaking free from the dark side's influence.
Han Solo is a great character to pair with them. His roguish charm and piloting skills add an interesting dynamic. He could be involved in a story where they all have to smuggle a crucial item across the galaxy while being chased by the Empire.
Ahsoka Tano would also be a good match. She's resourceful and has a lot of experience dealing with droids. She could either try to disable the vulture droid or find a way to use it to her advantage in a battle or mission.
Family relationships play a role too. Vaylin has a rather messed - up family situation in the Star Wars lore. Fanfics may explore how her family history affects her actions and decisions. For instance, how her relationship with her mother or father figures (even if they were not ideal parents) shapes her view of power and her place in the galaxy.
Ezra Bridger would be a great character to pair with Darth Vader. Their interactions could be really intense, as Ezra is a powerful young Jedi in the Rebels series and Vader has a history with the Jedi. It could lead to some great battles and also some interesting moments of understanding or misunderstanding between them.
Kanan Jarrus is another good choice. As a Jedi, he has the skills to face Vader, at least to some extent. Their interactions could explore the differences between the Jedi way and the Sith way. And Kanan's relationship with his crew could also play into the story, as he tries to protect them from Vader's wrath.
