What are some interesting Fire Force fanfiction ideas?

Well, you could create an OC fanfiction where the OC is a scientist who discovers a new way to combat Infernals that doesn't involve burning them. This OC might be initially rejected by the Fire Force but then proves their method's worth. Also, an OC with a special connection to the Adolla Burst could be interesting. Maybe they can communicate with the spirits of the Infernals or have visions related to the Adolla realm, which would lead to new adventures and revelations within the Fire Force world.

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 that Ghost Rider somehow gets transported to the world of Fire Force. He could team up with the Fire Force members to fight against a new type of infernal that has powers related to the underworld. His Penance Stare might be used to expose the true nature of some of the more mysterious infernals or even some corrupt individuals within the Fire Force organization.

The OC could be a scientist who is working on a new way to control the Infernals without having to kill them. Tamaki is assigned to protect the OC as there are those who oppose this new method. As they spend time together in the lab and during field tests, Tamaki becomes fascinated by the OC's intelligence and dedication. The OC, in turn, is charmed by Tamaki's positive attitude. They might face opposition from within the Fire Force, but their relationship and the OC's research continue to progress.

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.

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.

One interesting RWBY and Fire Force fanfiction could be a crossover where the characters from both universes team up to fight a common enemy. For example, the Huntsmen and Huntresses from RWBY could join forces with the Fire Force soldiers to combat a powerful Grimm - like infernal hybrid. This would create unique battle scenarios and character interactions.

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 exploring an alternate universe where the Battle Force 5 team has different powers or vehicles. For example, instead of their regular rides, they could have flying saucers with unique offensive capabilities.

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.
