A possible fanfiction could involve Rogue Ahsoka Tano being transported to a post - apocalyptic world. She then uses her combat skills and wisdom to help the survivors rebuild their society. Along the way, she discovers new aspects of the Force that are unique to this desolate world.
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 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.
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.
You could start by thinking about what would make Ahsoka Tano go rogue in the context of this crossover. Maybe she discovers a dark secret within the Jedi Order in this new setting. This could be the catalyst for her actions. Then, build a plot around her journey to expose this secret or fight against those who are trying to keep it hidden. Along the way, she could encounter various characters who either help or hinder her progress.
She could have Clone Troopers as her allies. Some of them might have defected with her and believe in her innocence. They could provide military support and loyalty.
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 idea could be a crossover where Naruto and Ahsoka meet in a dimension rift. Naruto's chakra and Ahsoka's connection to the Force could lead to some interesting power combinations and adventures as they try to find their way back to their respective universes.
One idea could be a story where Anakin and Ahsoka are reunited after a long time apart. Maybe Anakin has been on a secret mission and Ahsoka has been exploring new parts of the galaxy. When they meet again, they have to work together to face a new threat that is endangering the Jedi Order.
First, you need to decide on the crossover universe. If it's with another Star Wars era, research that era thoroughly. For example, if it's the Old Republic, understand the politics, the different species, and the Force - using orders. Then, plan the betrayal carefully. It should be something that makes sense for the character of Ahsoka. For instance, it could be a betrayal of trust based on a misunderstanding or a character's hidden agenda. Next, develop Ahsoka's reaction. Will she be angry, sad, or more determined? Write her internal monologues to show her emotions. Also, think about how the two universes will interact after the betrayal. Will there be new alliances formed? Finally, don't forget to add some action and adventure to keep the readers engaged.
One idea could be Ahsoka getting transported to the DC universe and teaming up with Batman. She could use her combat skills and Force - sensitivity to help him fight against Gotham's villains. Another plot could involve her meeting Wonder Woman and learning about the different types of power and heroism in the DC world. Maybe she gets caught in the middle of a battle between the Justice League and their enemies and has to use her Jedi wisdom to broker peace.
A frequent theme is identity. In a crossover like 'Ahsoka in the DC Universe', she has to redefine herself among all these new and powerful characters. Adaptation is another common theme. For example, in 'Ahsoka and the Avatar Crossover', she has to adapt to the concept of bending and the different power structures in that world. Also, the theme of discovery is often present. In 'Ahsoka's Multiverse Adventure', she discovers new powers, new species, and new ways of thinking as she jumps from one universe to another.
