In a more light - hearted plot, Ahsoka could be attending an intergalactic convention (yes, it's a stretch but it's fanfic after all) and Jack Darby is there representing the Autobots in a cultural exchange. They meet and find that they have a lot in common in terms of their values and experiences in fighting for the greater good. They then embark on a series of misadventures at the convention while also learning from each other's cultures and fighting styles.
One possible plot could be that Jack's mutant powers allow him to better communicate with the Transformers on a mental level. This new ability helps the Autobots in their battles against the Decepticons as he can relay information faster and more accurately.
You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fan - created works, so there's a good chance you'll find a fanfic about Ahsoka and Jack Darby there.
Well, it could start with Jack Darby being a huge Iron Man fan in his own Transformers universe. One day, he stumbles upon a strange energy source that gives him powers and abilities similar to Iron Man. He decides to use these new powers to protect his city from the Decepticons in a more high - tech and flashy way than before. Along the way, he might face some challenges like dealing with the Autobots who are skeptical of his new powers, or having to face a new and powerful Decepticon that is attracted to his new - found technology. He also might try to reverse - engineer his powers to create more advanced technology for the Autobots to use in their fight against the Decepticons.
One possible plot could be that Naruto and Ahsoka are brought together through some sort of interdimensional rift. They then have to learn about each other's worlds and powers in order to find a way to get back to their respective universes. Along the way, they might face common enemies that are drawn to the energy of the rift and team up to defeat them.
Another plot could involve Percy Jackson being sent to Jack Darby's world. Percy would have to deal with the new technology and different threats there. Maybe he discovers that some of the ancient monsters from his world have a connection to the technology in Jack's world. Jack and Percy would then have to team up to stop these threats from spreading chaos in both their worlds.
One possible plot could be that they first meet in a rather unexpected situation. Maybe Jack is on one of his adventures and stumbles upon Souls Prime in a time of need. Their connection grows as they face challenges together, like fighting off some common enemies. As time passes, they realize their feelings for each other are more than just friendship and decide to get married. Their wedding could be a grand event where friends from both of their worlds come together to celebrate.
One possible plot could be that Jack discovers a superheroine while on one of his adventures with the Transformers. She could be from a parallel dimension where superpowers exist, and Jack has to figure out how to get her back home. Along the way, they face challenges together, like attacks from Decepticons who see her powers as a threat or a new villain that emerges because of the disruption between their two worlds.
Well, it could start with some sort of misunderstanding between Jack and Raeder that leads to a fight. Maybe Jack suspects Raeder of something wrong, like stealing or betraying a group they are both part of.
One possible plot could be a story where Darth Vader, in his full potential, has a moment of self - realization during a battle against Ahsoka. He might start to question his dark path and Ahsoka, seeing this glimmer of Anakin in him, tries to pull him back to the light. It could be a complex emotional journey for both characters as they grapple with their past relationship as master and apprentice.
Well, in this kind of fanfic, it could be that Ahsoka is trapped in a collapsing structure while on a mission. She tries to use the Force to hold it together long enough for others to get out. But the strain is too much and she ends up being crushed when the structure finally gives way. Her death could then be a catalyst for her friends to re - evaluate their own lives and fight even harder against the forces of evil.
