Maybe Sasuke is a Jedi Knight who goes rogue because he wants to find a way to bring back someone he lost, similar to his past in Naruto. Sakura, as his former partner, tries to bring him back into the Jedi Order. They travel across different star systems, facing pirates, Sith assassins, and other threats, all while their relationship is tested and evolves.
One storyline could be that Sasuke is a fallen Jedi and Sakura is sent to find him. She has to face many challenges in the galaxy to reach him and then convince him to return to the light side. Another could be that they are both on opposite sides of a galactic war. Sasuke is with the evil empire - like the Sith - and Sakura is with the rebels. They have to fight each other but also deal with their feelings.
A possible storyline is that Sasuke discovers an ancient Sith artifact that gives him great power. Sakura, as a Jedi, tries to stop him from using it for evil. Along the way, they both learn more about the Force and themselves. There could also be a story where they are both stranded on a strange planet. They have to work together to survive and in the process, they start to see each other in a new light.
Another storyline could be Gohan searching for a way back to his own universe. In this journey, he teams up with a group of smugglers who are on the run from the Empire. Along the way, he discovers secrets about the Force that are unique to the Star Wars universe and has to decide whether to share this knowledge with his own universe if he ever gets back.
Well, Sasuke could be like a brooding Jedi. His skills with a lightsaber might be similar to his ninja sword skills. He'd be constantly seeking more power, perhaps tempted by the dark side. Sakura, on the other hand, could be a healer Jedi. She would use her medical knowledge from the Naruto world to help injured Jedi. Her strong will would make her a great Jedi in the Star Wars universe.
One possible storyline could be that their son inherits Sasuke's Sharingan and has to learn to control it. Sakura, being a skilled medic, trains him in self - control and discipline. And Sasuke takes him on missions to teach him combat skills.
One possible storyline could be that Venom is lured to Earth by a powerful villain who wants to use Venom to take on the Avengers. But Venom realizes he's being used and teams up with the Avengers to take down the real villain.
A third storyline could be about the relationships within the village. The news of Sasuke and Sakura's pregnancy spreads, and the whole village is excited. Naruto, as Sasuke's friend, could be very involved, offering his support and also joking about how their kids will grow up together. The fanfiction could explore how the village prepares for the arrival of Sarada, with people bringing gifts and sharing their own stories of parenthood. Meanwhile, Sasuke and Sakura are just enjoying this special time together, despite any external pressures.
One popular storyline in both official Star Wars and fanfiction is the origin of certain characters. For example, in fanfiction, there are many stories exploring Darth Vader's life before he turned to the dark side. In the official Star Wars universe, we got some insights, but fanfiction often delves deeper, imagining his relationships, his training, and the events that led him to his fateful decision. Another common one is the post - Endor era, where fans and the official works explore how the galaxy rebuilds and what new threats or alliances might emerge. Jedi - Sith relationships also make for great storylines, like the balance between the two and the potential for redemption among Sith characters.
One plotline could be that Sasuke is from a hidden ninja - like island in the One Piece world. He is sent out on a mission to find a Devil Fruit that has the power to unlock the secrets of his clan's past. Along the way, he crosses paths with the Straw Hat crew and initially clashes with them due to his cold and brooding nature.
A storyline could involve a time - travel element. Naruto, Sasuke, and Sakura are sent back in time and find themselves in a situation where they have to get married to change the future. They start off as reluctant partners but as they spend more time together in the past, they develop real feelings for each other. They also have to hide their relationship from their past selves and other characters while trying to figure out how to change the future.
One storyline could be Gohan trying to find a way back to his own universe while helping the heroes in MHA. Another could be Gohan teaching Izuku Midoriya some of his more advanced combat techniques.
In Star Wars Rebels, a popular storyline is the crew of the Ghost fighting against the Empire. In fanfiction, there are many where a new character joins the Rebellion. For example, some fics focus on a young Force - sensitive individual finding their place among the rebels.
