In this fanfic, it could start with the Ghost Squadron being in trouble. They are outnumbered by a large Imperial force. Ahsoka senses their distress through the Force and comes to their rescue. After the battle, they exchange stories. Ahsoka tells them about her time with Anakin and the Jedi Order. The Ghost Squadron members share their own experiences fighting against the Empire. They then decide to travel together for a while, with Ahsoka helping them with their ship's repairs and combat training, and they in turn introduce her to new allies in the Outer Rim.
The main characters would be Ahsoka and Ezra. Ahsoka has seen so much in her life, from the Clone Wars to the fall of the Jedi. Ezra, on the other hand, is just starting to understand his powers. Their meeting could be a turning point for Ezra's growth. Also, Hera is important as she is the one who holds the Ghost Squadron together. Her interactions with Ahsoka, especially in terms of strategy and leadership, could be a major part of the fanfic. And of course, Kanan, who can bridge the gap between Ahsoka's more traditional Jedi knowledge and the unorthodox ways of the Ghost Squadron.
Well, perhaps Ahsoka and the Ghost Squadron could team up to fight a common enemy. Maybe they'd share their different combat strategies and learn from each other.
The fact that it allows for creative interpretations. Writers can create their own versions of Ashoka's story. It could be about her having different powers or facing new challenges.
One common theme is mentorship. Anakin often acts as a mentor to Ashoka, guiding her in the ways of the Force. Another theme is friendship. Their relationship is a deep friendship that withstands many challenges. For example, in some fanfics, they support each other during difficult battles or when facing political intrigue within the Jedi Order.
One common theme is her journey of self - discovery. Since she left the Jedi Order, many fanfics explore how she figures out who she is outside of that structure.
There might be a rookie in the squadron who is also a main character. This character could be learning the ropes, making mistakes, but also showing great potential. Their journey of growth within the squadron can be a central part of the fanfic.
Well, perhaps the plot could involve Ashoka seeking Yoda's wisdom after a long and arduous journey. She might be facing a new and powerful enemy that she doesn't fully understand. Yoda, with his centuries of knowledge, could offer her insights on the Force and how to combat this threat. Maybe he would teach her a new way to use the Force that she hadn't considered before, leading to a final showdown where Ashoka is able to defeat the enemy using Yoda's teachings.
For an Ashoka crossover fanfic, you could consider a crossover with the Old Republic era. Ashoka could meet some of the ancient Jedi and Sith. She could be involved in uncovering an ancient mystery that spans both her time and the Old Republic era. This would allow for a lot of exploration of different Jedi and Sith philosophies and powers.
