A really interesting plot for a Star Wars Ahsoka Jedi Knight fanfiction could be that Ahsoka is wrongly accused of a crime she didn't commit. She has to go on the run while also trying to clear her name. Along the way, she meets some unlikely allies, like a group of smugglers who initially don't trust her but come to see her as a true hero. She has to use her Jedi skills in creative ways to evade capture and prove her innocence, all while facing the real culprit who is trying to frame her to further their own dark plans.
Well, a great plot might involve Ahsoka traveling through time. Maybe she gets sent back to the days of the Old Republic and has to interact with the great Jedi Masters of that era. She could learn new forms of lightsaber combat or ancient Jedi wisdom that she then brings back to her own time to use against a new enemy. Also, she could face a moral dilemma where she has to choose between following the traditional Jedi Code or her own instincts when dealing with a new type of enemy that the Code doesn't quite cover.
Well, a cool plot might be that Ahsoka gets trapped in a Sith - created illusion world by Vader. In this world, she has to face her past traumas and fears related to Anakin's fall. Meanwhile, Vader is conflicted as he watches her struggle, memories of his past with Ahsoka resurfacing. Or there could be a story where they both are on a mission to retrieve a powerful Jedi/Sith artifact, and their paths cross in a race against time.
One idea could be that in the fanfiction, Ahsoka is kidnapped by a group of Sith cultists who want to use her connection to the Force for their dark rituals. They could take her to a hidden lair on a remote planet.
A young Twi'lek Force - sensitive. Twi'leks are known for their grace and beauty, and this character could bring a new perspective. Maybe they have a unique way of using the Force that Ahsoka has never seen before. Another could be a droid with a malfunctioning memory core that holds secrets about the Jedi Order from a long - forgotten era.
One idea could be an OC Jedi who discovers a long - lost Jedi technique that gives them unique powers. This could lead to a series of adventures as they try to master it while also facing off against Sith or other enemies who want to steal the knowledge for themselves.
A plot could involve Rex and Ahsoka getting caught in a time - travel anomaly. They end up in a different era of the Star Wars universe, like the Old Republic. There, they have to figure out how to get back while also dealing with the unique challenges and enemies of that time period. They might even meet some of their ancestors or Jedi from a long - gone era.
One plot idea could be that Ahsoka and Barriss are forced to team up on a mission to a remote planet. They initially have their differences due to past events, but as they face various challenges together, like fending off dangerous creatures and dealing with a corrupt local government, they start to understand and respect each other more. Their relationship could develop from one of distrust to a strong friendship.
Perhaps in the fanfiction, Ahsoka and Thrawn end up on a desolate planet. They have to rely on each other's knowledge - Ahsoka's Jedi wisdom and Thrawn's strategic military mind - to survive and find a way off the planet. As they do so, they begin to understand the motives behind their respective actions in the greater galactic conflict.
One plot idea could be Fives and Ahsoka teaming up to uncover a hidden Sith plot within the Jedi Order. They might start noticing strange behavior among some Jedi and use their unique skills to dig deeper.
One idea could be a gunslinger clone who is on a mission to rescue a group of captured Jedi. He uses his unique shooting skills to fight off droids and Sith assassins along the way.
A great plot could be Ahsoka having to face a Sith Lord who has a personal vendetta against her. This Sith Lord could be an old enemy she thought was dead. Or perhaps a plot where she is training a new group of Force - sensitive individuals in a post - Empire galaxy, and they face threats from remnants of the Imperial forces. Also, a story where she goes on a quest to find an ancient Jedi artifact that has been lost for centuries.
