For Rise of Skywalker fan fiction, you could consider a time - travel plot. What if a character from the movie went back in time to change the events that led to Palpatine's return? It would create a whole new set of storylines. You could also write a story about the training of the new Jedi. How Rey trains the next generation of Force - sensitive individuals, what challenges she faces, and how she imparts the teachings of the Jedi in a post - Palpatine galaxy.
One interesting idea could be exploring alternate endings. For example, what if Rey had chosen a different path? Another could be delving deeper into the backstories of the new characters introduced in the movie. Maybe there are hidden motives or past relationships that were not fully explored in the official film.
One idea could be exploring the backstory of a minor character in the movie. For example, a Stormtrooper who has doubts about the First Order and decides to defect. This could involve their internal struggle between loyalty to the regime they were raised in and their newfound moral compass.
Rey is an obvious choice. Her journey from a scavenger to a powerful Jedi is full of potential for further exploration. You could write about her internal struggles with her newfound power and her place in the galaxy. Finn is also interesting. His growth from a stormtrooper to a Resistance hero can be delved into deeper. For example, his experiences in the First Order and how they still affect him during the fight against Palpatine.
Perhaps they have to team up to convince a group of war - torn planets to join the Rebel Alliance. They use their unique abilities, Luke's connection to the Force and Leia's diplomatic skills, to sway the planets. Along the way, they also learn more about their family's history and how it can help in their mission.
A great plot for a fanfiction could be a story that focuses on the backstories of the new characters introduced in Rise of Skywalker. For example, the origins of the Knights of Ren. Were they all from different planets? What led them to follow Kylo Ren? You could also write about a time - traveling adventure where a character from the past comes to the events of Rise of Skywalker to change the outcome for the better or worse.
One idea could be exploring an alternate ending where Rey doesn't take the Skywalker name. Maybe she decides to create her own legacy independent of the Skywalker family. Another could be delving deeper into the relationship between Finn and Poe. In the fanfiction, they could have a more complex backstory together, like they were childhood friends separated during the First Order's rise.
One idea could be exploring the backstory of a minor character in the movie. For example, a Stormtrooper who has doubts about the First Order and decides to secretly help the Resistance. This could add a new perspective to the events of the film.
Well, a cool Luke Skywalker fan fiction might involve him encountering an ancient Jedi order that was thought to be extinct. He could learn long - lost Jedi techniques and use them to face a new, powerful Sith threat. Or perhaps a story where he forms an unlikely alliance with a group of smugglers to take on a corrupt Imperial remnant. There are also those fan fictions where Luke has a romantic relationship with a character from a different species, which leads to some really unique cultural exchanges and adventures in the Star Wars universe.
Perhaps a fan fiction where Luke and Leia travel back in time to the days before the Clone Wars. They could use their knowledge of the future to try and prevent the events that led to the rise of the Empire, all while trying to keep their identities a secret.
One interesting storyline could be exploring the backstories of minor characters in more depth. For example, delving into the past of a Stormtrooper who has a change of heart. Another could be a different take on the relationship between Rey and Kylo Ren, perhaps a more platonic exploration of their connection based on their shared Force sensitivity. And a third could be creating a new adventure for Finn, Poe, and the rest of the Resistance that wasn't shown in the movie.
