Perhaps a fanfiction where they both find themselves on a mysterious planet. They have to figure out the planet's secrets and survive its strange inhabitants. Along the way, they strengthen their bond and learn more about each other's growth since they last saw one another.
One plot idea could be that the OC is a fellow Jedi in training. They start off as rivals, constantly competing in lightsaber duels and Force training exercises. As they face challenges together, like a Sith threat to the Jedi Temple, they gradually develop feelings for each other. Another idea is that the OC is a mechanic who helps Ahsoka repair her ship during a difficult mission. They bond over their shared love for adventure and over time, romance blossoms. A third idea could be that the OC is from a different planet with a unique culture. Ahsoka is intrigued by this culture and the OC's different perspective on life, leading to a romantic connection as they learn more about each other.
One idea could be a crossover with the Star Wars Rebels crew. Ahsoka could team up with Ezra and Kanan to face a new threat that combines elements from different eras of the Star Wars universe, like a Sith Lord using ancient Jedi artifacts in a new way. Another plot could involve a crossover with the Mandalorian. Ahsoka could cross paths with Din Djarin and Grogu, perhaps helping them in a battle against remnants of the Empire while also sharing her wisdom about the Force.
First, understand the characters well. Know their personalities, backstories, and how they interact in the official Star Wars universe. This will help you make their relationship in the fanfiction believable.
One plot idea could be Ahsoka finding herself in a parallel universe where she's considered a rogue Jedi. She has to team up with alternate versions of her friends to fight a common enemy. Maybe an ancient Sith cult has risen and they are the only ones who can stop it.
A possible plot could involve Ahsoka being betrayed by someone she trusts deeply within the Jedi or among her friends. This betrayal could be so severe that it pushes her over the edge, and she turns to the dark side for revenge. She then uses her newfound dark side powers to seek retribution against those who wronged her.
One idea could be Ahsoka traveling back in time to the Clone Wars era and changing a small event that has big consequences. For example, she might prevent a key battle from happening which then alters the relationships between the Jedi, the clones, and the Separatists.
A lemon fanfiction involving Ahsoka Tano and Captain Rex might explore their unspoken bond in a more romantic or emotional way. It could show them having deep conversations during a mission, perhaps in a moment of respite. However, it's important to note that such fanfictions often deviate from the official canon.
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.
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.
One idea could be a story where Galen Marek and Ahsoka Tano team up to face a new threat in the galaxy. They could combine their unique skills, Galen's powerful Force abilities and Ahsoka's combat and strategic knowledge. Maybe they meet on a neutral planet and at first are distrustful of each other, but as they face challenges together, they start to respect and rely on one another.
