Another idea could be that a clone has a special connection to a Rebel through some shared past experience during the Clone Wars. Maybe they were on opposite sides but now find themselves on the same side against the Empire. Their relationship could develop in unexpected ways, with the clone teaching the Rebel about the military strategies of the clones, and the Rebel showing the clone the more scrappy, underdog ways of the Rebels.
One interesting storyline could be about a clone who survived the Clone Wars and joined the Rebels. He could bring his unique combat skills and military knowledge to the Rebellion, causing some initial distrust among the Rebels but eventually proving his worth.
One interesting storyline could be a clone who starts to question Order 66 before it's executed.

One interesting storyline could be about a young Jedi who discovers the Darksaber during the Rebels era and has to learn to control its dark side influence. Maybe they struggle with the power it offers while also trying to use it for the good of the Rebellion.
A great fanfiction plot could be about an Inquisitor who starts to question the Empire's motives. They see the destruction and chaos the Empire is causing and begin to secretly help the Rebels. This would involve a lot of internal conflict as they struggle between their loyalty to the Sith and their new - found sense of right and wrong. For example, they might start by providing the Rebels with small bits of information that seem unimportant at first but end up being crucial in a major battle.
One interesting storyline could be an SI (self - insert) character who has the power to manipulate the Force in unique ways. They might use this power to help the rebels in unexpected battles, like being able to sense Imperial traps from afar and lead the rebels to safety. Another could be an SI who is a master of a long - forgotten form of lightsaber combat and teaches it to Ezra. This new form gives the rebels an edge in combat against the Inquisitors.
A possible storyline is Bendu being caught in the middle of a conflict between the Rebels and the Empire. It could show his struggle to maintain his neutrality while also being forced to take sides. This would explore his character's moral compass in a more complex way. For example, he might have to decide whether to use his powers to save innocent lives at the risk of revealing his true nature to the Empire.

Through a series of battles and self - discovery, they grow into a confident and skilled fighter. Another could be about a group of Rebels who discover a hidden Sith artifact during a mission and have to decide what to do with it, whether to destroy it or use it against the Empire. There could also be a story where a Rebel spy infiltrates an Imperial base and uncovers a secret weapon being developed.
Captain Rex is often a very popular character. He was a well - known clone in the Clone Wars, and in fanfiction set during the Rebels era, he can be a great link between the two time periods. His experience and leadership make him a central figure in many stories.
