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.
Well, start by choosing a strong crossover concept. Let's say you want to cross Ahsoka with the Mass Effect universe. In this case, the betrayal could come from a species that she initially thought was friendly but turns out to have its own motives. To write it, you need to establish Ahsoka's character in this new universe. Describe how she uses her Jedi skills in a different setting. Regarding the betrayal, make it a slow - burn process. Maybe small hints are dropped along the way until the big moment. After the betrayal, Ahsoka could start to question her own judgment. This internal conflict can be a major part of the story. And then, build towards a resolution where she either overcomes the betrayal or uses it as a stepping stone to something greater.
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.
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.
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.
Another important aspect is the plot. It should be engaging and not just centered around the relationship. Maybe they have to stop an ancient Sith artifact from being activated or solve a mystery that threatens the galaxy. By having a strong plot, the relationship between Ahsoka and the male OC will be more interesting as they face challenges together.
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.
In Ahsoka Tano crossover fanfiction, including Obi - Wan Kenobi would be amazing. He and Ahsoka could have some really deep conversations about Anakin. Qui - Gon Jinn could also be a good character. Ahsoka could learn from him about the Living Force in more detail. And from the new Star Wars trilogy, Finn would be a great addition. He and Ahsoka could train together in combat, with Ahsoka teaching Finn more about the Force - sensitive combat skills.
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 possible reason could be disillusionment. In some crossovers, she might see the Jedi Order's flaws more clearly when exposed to different cultures or ideologies from the crossover elements. For example, if it's a crossover with a more individualistic society, she may start to question the Jedi's collectivist approach.
To write a believable character arc for Ahsoka, start with her existing traits. She's strong - willed and independent. Maybe have her start the fanfic being a bit overconfident and then face a series of setbacks that make her question herself. For example, she could lose a battle against a new enemy and then have to relearn her fighting techniques.
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.
