An interesting plot could be an OC who is a mechanic with a mysterious past. They join the Rebels and start to tinker with their ships and weapons, but they also have a connection to an ancient Jedi artifact. As they work with the Rebels, they gradually uncover the secrets of the artifact and how it can be used against the Empire. Or perhaps an OC who is a youngling that was hidden away during Order 66 and now, years later, emerges to join the Rebels and seek revenge on the Empire while also learning the ways of the Force from the few remaining Jedi.
A plot idea could be an OC who is an artist. They use their art to spread propaganda for the Rebellion, creating images that inspire hope and resistance among the people. However, the Empire is after them because their art is seen as a threat. Another could be an OC who is a diplomat's child. After their parents are killed by the Empire, they use their diplomatic skills to form alliances for the Rebels among different planets and species. They also have to deal with the internal politics of the Rebellion as they try to prove themselves useful.
One idea could be exploring the backstory of a minor character in the series. For example, you could write about how a Stormtrooper decided to defect and join the Rebels. Another plot could involve a new threat that the Rebels have to face, something that even the Empire is not fully aware of. Maybe a powerful ancient Sith artifact is discovered and both the Rebels and the Empire are racing to get it.
A plot could be that the OC is a long - lost relative of Ezra's. They meet during a battle and initially don't realize their connection. As they get to know each other, they start to notice similarities in their abilities and appearance. Eventually, they discover their family tie and it strengthens their bond within the Rebellion.
One plot idea could be Kanan and Hera getting stranded on a desolate planet and having to rely on each other to survive. They could face dangerous native creatures and have to use their unique skills to build shelter and find food. Another idea is a story where they go undercover together on an Imperial - controlled world, pretending to be a couple to gather intelligence.
There are several great plot ideas. For instance, imagine a situation where Yoda, before his death, set in motion a series of events that are only starting to unfold during the Rebels' time. Maybe he planted the seeds for a new Jedi order in a very secretive way. A young Rebel might stumble upon these secrets. Another idea is that Yoda's teachings, which were thought to be lost, are rediscovered by the Rebels through an ancient Jedi artifact. This discovery changes the way they approach the fight against the Empire. And what about a story where Yoda's influence reaches out to a non - Force - sensitive character in Rebels, inspiring them to do great things for the Rebellion in a different way?
One idea could be a crossover with the original Star Wars trilogy characters. Maybe the Rebels crew teams up with Luke Skywalker and Han Solo to take on a new, powerful Sith threat. This would bring together the scrappy underdog feel of the Rebels with the classic heroism of the original trilogy.
One plot idea could be that your Jedi OC is a long - lost relative of one of the main characters in Star Wars Rebels. For example, a cousin of Ezra. They come to Lothal seeking their family and end up getting involved in the Rebellion. Another idea is that the OC is a Jedi who has been in stasis for years and wakes up during the Rebels era. They have to quickly adapt to the new situation and help the Rebels with their ancient Jedi knowledge. A third idea is that the OC is a Jedi who was trained by a Sith - turned - Jedi and has some unorthodox ways of using the Force that the Rebels are initially skeptical of but later come to rely on.
One idea could be a crossover with the original Star Wars trilogy characters. For example, having Luke Skywalker meet the Rebels crew and learn from their guerilla warfare tactics against the Empire. It would be exciting to see how their different fighting styles blend and how they interact with each other.
One idea could be exploring the post - Rebels era and how the actions of the main characters have influenced the new generation. Maybe a young Jedi discovers an old artifact left by Ezra Bridger and it sets them on a journey to learn more about the Rebels' fight.
A character could experience a moral transformation. A former Imperial who has joined the Rebels might start to transform back to his old ways due to the stress and hardships of the Rebellion. This internal struggle could be a central part of the fanfiction. The other Rebels would then have to decide what to do with him - try to reform him again or cut their losses. It would show the complex nature of the Rebels' cause and the different types of people it attracts.
One idea could be about an OC (Original Character) in the corps who discovers a long - lost Jedi artifact. This discovery could lead to a race against the Sith to obtain it. Another plot could involve an OC with unique Force - related abilities in the corps trying to unite different factions within the Star Wars universe to fight a common enemy like the Yuuzhan Vong. Or perhaps an OC in the corps uncovers a conspiracy within the military ranks that threatens the stability of the galaxy.
