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.
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 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.
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.
One popular 'Ahsoka Tano x OC fanfiction' is 'The Journey with Ahsoka'. It focuses on an OC who becomes Ahsoka's partner in a quest to find a lost Jedi artifact. Another good one could be 'Ahsoka and the New Ally' where the OC has unique Force abilities and they team up to face a new Sith threat. There's also 'Ahsoka's Unexpected Bond' which delves into a more emotional connection between Ahsoka and the OC as they overcome various challenges together.
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.
Another idea is a crossover where Rogue Ahsoka Tano stumbles upon a world full of magic. She has to use her Jedi skills in combination with the new magical elements she discovers there. For example, she might learn to combine the Force with magic spells to defeat an evil sorcerer.
One idea could be a crossover with Star Wars Rebels. Ahsoka could be betrayed by someone she thought was an ally in the fight against the Empire. Maybe a new character who was secretly working for Thrawn all along. This would lead to a complex plot where Ahsoka has to not only survive but also figure out who she can trust again.
