In a fanfiction centered on Numa from Star Wars Rebels, it could explore her relationships. She might form a strong bond with a new character, a young Jedi in hiding. Together, they learn from each other and help spread hope among the Rebel cells. Numa could teach the Jedi about the importance of the common people in the fight against the Empire, while the Jedi could train Numa in some basic self - defense skills.
One possible fanfiction could be about Numa's growth within the Rebellion. Maybe she discovers a new ability that helps the Rebels in a crucial battle. For example, she could have an uncanny sense for detecting Imperial traps, which she uses to lead the Rebels to safety and victory.
Maybe Numa stumbles upon a hidden Sith artifact on Lothal. This discovery could put her in danger as both the Empire and some rogue elements within the Rebellion want to get their hands on it. She has to decide what to do with it and who to trust, which would be a great character - building story.
There could be a fanfiction where Ezra, from Star Wars Rebels, discovers the legacy of Revan. Maybe Ezra stumbles upon an ancient Jedi artifact that has a connection to Revan. He starts to have visions of Revan's battles and is inspired by his unique blend of light and dark side use, which could lead Ezra to question his own understanding of the Force.
In many Star Wars Rebels fanfictions, Ezra's crying moments can be quite impactful. It might be due to the loss of a mentor or a difficult situation. For example, if Kanan died in the fanfiction, Ezra would be devastated and his crying would show his deep emotional bond with his master.
Perhaps she was originally from a planet that the Rebels are trying to protect. When she discovers this, she has an internal struggle. She could befriend a rebel who makes her see the Empire's true nature. This friendship could be the turning point for her character. She might then use her stormtrooper training and equipment to assist the Rebels in their fight against the Empire.
A fanfiction centered around Dawn Syndulla could explore her relationships. She might develop a close friendship with a new character, perhaps an alien from a species she has never interacted with before. Their adventures together, learning about each other's cultures and helping the Rebellion in the process, could be a great plot for a story.
A fanfiction could explore what would happen if Anakin Skywalker had survived and joined the Rebellion during the events of Star Wars Rebels. He would bring his incredible combat skills and Jedi powers. His relationship with other characters like Hera Syndulla and Sabine Wren would be interesting to develop, as they would have to learn to trust this once - fallen hero.
One great fanfiction idea could be Obi - Wan secretly guiding Ezra Bridger in his Jedi training during the events of Star Wars Rebels. Maybe he appears as a Force ghost only Ezra can see at first. This would add an interesting dynamic as Ezra is trying to find his way as a Jedi without a proper master on hand.
The theme of power and politics also emerges. How NUMA entities might influence or be influenced by the power struggles in the Star Wars universe, such as the fight between the Jedi and the Sith or the political machinations in the Galactic Republic and the Empire.
One great Star Wars Rebels Rex fanfiction is 'Rex's Redemption'. It shows Rex finding his place in the Rebellion after his Clone Wars experiences. Another is 'Rex and Ezra's Bond', which focuses on the relationship between Rex and Ezra Bridger. There's also 'Rex's Leadership in the Rebels' that details how Rex uses his military knowledge to help the Rebels.
Sabezra fanfiction adds a lot to the fandom. It allows fans to explore the relationship between Sabine and Ezra in ways that the show might not have fully. For example, it can give more in - depth looks at their feelings for each other.
