A common theme is the exploration of their relationship. It could be a platonic friendship where they support each other in their Jedi - like quests. Or it could be a more mentor - mentee relationship, with one guiding the other in different aspects of the Force. There are also fanfics that explore a potential romantic relationship between them, though this is more of a debated and less - common theme. Some fanfics also focus on them in alternate universes, like a modern - day setting where they still have their Force - related abilities.
One popular theme is their training together. Since both are strong in the Force, imagining them sharing knowledge and training techniques is quite appealing. Another theme is them going on adventures. They could team up to face a new threat in the galaxy.
Many Ahsoka and Luke fanfics deal with the idea of them bringing back the Jedi Order. They could combine their different experiences with the Jedi way and try to rebuild what was lost. Another theme is them encountering ancient Jedi or Sith artifacts and having to deal with the power or knowledge that these artifacts hold. And of course, there are fanfics that simply put them in the middle of a big galactic conflict and see how they interact and contribute to the resolution.
Another theme is the 'what - if' scenarios. For example, what if Rex had been with Ahsoka during certain key events that she faced alone in the official story? It adds an interesting twist to the narrative. And some fanfics also focus on their relationship post - Clone Wars, how they might reunite and what that would be like considering all the changes that have occurred.
One popular theme is Luke's further training as a Jedi. Many fanfics explore what he could have learned beyond what was shown in the movies. Another theme is his relationships, like his friendship with Han Solo and Leia in more depth or potential romantic relationships. And there are also fanfics about Luke's role in rebuilding the Jedi Order, showing his leadership and the challenges he faces in that regard.
One common theme is the passing of Jedi knowledge. Since Ahsoka has more experience and Luke is eager to learn, a lot of fanfictions explore how she imparts her wisdom about the Force, lightsaber combat, etc. to him. Another theme is their combined strength against a common enemy. They are both powerful Jedi, so it makes sense for them to team up against threats in many stories.
One common theme is their shared journey in the Force. Since they both have a deep connection to the Force, fanfictions often explore how they can learn from each other and grow in their understanding of it. For example, they might have joint Force - related adventures.
One possibility could be that they meet during a time of great danger for the galaxy. Maybe a new threat has emerged that neither the Jedi teachings Ahsoka has nor Luke's newfound Jedi knowledge can easily combat alone. They could start off as a bit wary of each other, given their different experiences with the Jedi Order. But as they face challenges together, they learn from each other's strengths. Ahsoka could teach Luke about the more ancient Jedi ways she learned from Anakin and the Clone Wars era, while Luke could share his insights on the Force that he has gained from his own journey and training with Yoda and Obi - Wan.
One popular theme is her journey as a Jedi. This includes her training, her struggles with the Jedi Code, and her relationship with the Force. Another theme is her friendships, like with Clone Troopers. Her adventures in different parts of the galaxy are also a common theme.
One idea could be that Ahsoka tells them stories about their father, Anakin Skywalker. She could share the good times she had with him, like their adventures together. This would give Luke and Leia a more personal connection to their father before they fully understand their heritage.
Many 'ahsoka' fanfics focus on her as a strong female character. They might explore how she breaks gender norms in the Star Wars universe. Her skills as a warrior and her wisdom are often highlighted. Additionally, fanfics might explore her connection to the Force in new and interesting ways, like her discovering new Force abilities or her role in ancient Jedi prophecies, all without any erotic elements.
If they trained together, Luke would learn a great deal from Ahsoka. She has a different style of combat and a unique understanding of the Force. Luke might pick up new lightsaber techniques that could enhance his own fighting ability.
Ahsoka could introduce Luke and Leia to some of her friends or allies. These new characters could be from different species or backgrounds. This would expand Luke and Leia's view of the galaxy and the different kinds of beings that inhabit it. It could also lead to new storylines and adventures as they interact with these new friends.
