You could also write about Naruto forming a special force within the Hidden Leaf Village. This force would consist of some of the most talented ninja from different clans. They would be trained by Naruto himself to face threats that are beyond the capabilities of the regular ninja forces. It could explore how Naruto's leadership skills and his understanding of different ninja abilities would help in creating a formidable team.
A great concept for a 'Naruto Shining Force' fanfiction could be a time - travel story. A Naruto character, like Kakashi, travels back in time to the era of Shining Force. He then uses his ninja skills and knowledge to help the Shining Force in their battles. He could teach them some ninja stealth techniques, and in return, learn about their unique forms of magic. This would create an interesting dynamic between the two different universes and their abilities.
Another interesting plot could involve Naruto teaming up with characters from the Star Wars universe who have also been brought into the Naruto world. Imagine Naruto and Luke Skywalker working together to defeat a common enemy that combines the threats from both universes. They could learn from each other's powers and techniques, making for an exciting story.
One idea could be that the self - defense force in the Naruto world has to deal with a new threat from a hidden underground organization that is stealing chakra - based weapons. Another could be a story where members of the self - defense force are trained by some of the legendary ninjas like Naruto himself to face an upcoming large - scale war. A third plot idea might be that the self - defense force discovers a new type of ninjutsu that has the potential to either save or destroy the ninja world and they have to decide what to do with it.
One idea could be that Naruto's ability to control chakra is somehow combined with the Fire Force's pyrokinetic abilities. For example, Naruto might teach the Fire Force members some of his chakra control techniques, which could enhance their ability to control their flames in a more precise way.
One idea could be exploring the backstory of Rey's parents in more detail. Maybe they were part of a secret Jedi order that was in hiding. Another could be a story about Finn's life before he defected from the First Order, like his training and relationships with other stormtroopers. Also, a fanfiction could focus on Kylo Ren's struggle with the light side of the Force that he tries to suppress.
You could write a fanfiction that delves deeper into the relationship between Arthur and Shinra. Maybe they get into a big argument over their different approaches to being a hero. Shinra believes in using his powers for the greater good in a more practical way, while Arthur is all about living out his 'knight in shining armor' fantasy. This argument could lead to them going their separate ways for a while, and then having to come back together to face a powerful Infernal that neither of them could defeat alone.
You could write a fanfiction where Gajeel enters Dragon Force during a major battle against a powerful dark guild. In this story, his transformation could turn the tide of the battle and inspire his comrades. He could also have some internal struggle during the transformation, like dealing with the overwhelming power and the fear of losing control.
One idea could be a crossover with the X - Men universe. The Phoenix Force could interact with different mutants, like Wolverine. Maybe it could enhance his healing factor in a new and unexpected way. Another could be a crossover with the Avengers. The Phoenix Force could be a threat that they have to face together, leading to some epic battles and interesting team - ups. For example, Iron Man might try to create a device to contain the Phoenix Force, while Thor uses his godly powers to try and subdue it.
A great fanfiction could revolve around the origin of the Swap Force. You could explore how the concept of swapping parts came to be in the Skylanders world. Maybe it was a result of an ancient magic experiment gone wrong or right, and how this ability has shaped the battles and relationships in Skylands.
A really cool Glitter Force Crossover Fanfiction could involve a time - travel aspect. Maybe the Glitter Force travels back in time to a period when magic was first discovered. There, they meet ancient mages and learn new spells that they can bring back to their own time to use against their foes. Or they could cross over with a fairy - tale world, like Wonderland from Alice in Wonderland, and have to navigate through the strange and magical landscape while still maintaining their Glitter Force duties.
