In some fanfictions, they might team up against a common enemy that was not in the original story. This could show a different side of their relationship, like Natsu having to rely on Seilah's more strategic thinking.
Seilah is also a main character in this context. She has her own set of powers and a rather complex personality in the Fairy Tail universe, which can be further explored in fanfiction.
One interesting plotline could be Seilah's redemption arc. Maybe she tries to atone for her past actions and find a new place in the Fairy Tail guild. Another could be her teaming up with other characters to face a new, powerful dark magic threat that has nothing to do with any adult themes.
In certain Fairy Tail Natsu agent fanfictions, the story focuses on Natsu's relationships while on his agent missions. For example, he might have to keep his identity a secret from a new friend he makes in a foreign town. This adds an element of drama and secrecy to the story. Some fanfictions also delve into Natsu's past and how it influences his actions as an agent. His dragon - slayer heritage could play a significant role, such as having special abilities that are useful in his agent work but also attract unwanted attention.
There's a fanfiction where Natsu and Gray accidentally switch bodies. It's really funny as they try to act like each other in front of the guild members. Natsu in Gray's body has a hard time controlling the ice magic and Gray in Natsu's body keeps accidentally setting things on fire. But through this chaos, they gain a deeper understanding of each other.
One interesting 'natsu fairy tail master fanfiction' could be about Natsu going on a solo adventure to a far - off land not yet explored in the original Fairy Tail world. He might encounter new magical creatures and learn unique forms of magic.
Well, in many of such fanfictions, Natsu might use his unique fire - based magic in really creative ways to save the Fairy Tail guild. For example, he could combine his dragon slayer magic with some unexpected elements from the environment to defeat a powerful enemy threatening the guild.
One interesting fanfiction could be where Natsu and Happy discover a hidden magic that only they can use. This new magic leads them on an adventure to a far - off land filled with strange creatures. They have to use their combined skills and the unique bond between them to overcome challenges.
In this fanfiction, the 'broken' Natsu might have different powers or abilities. Maybe his magic has been affected in some way, leading to new forms or techniques. This could open up a whole new world of battles and strategic elements in the story. The fanfiction could also explore how the Fairy Tail guild as a whole responds to a broken Natsu. Do they rally around him? Or are there some who are afraid of this new, changed Natsu? All these aspects make the 'Fairy Tail Broken Natsu Fanfiction' an interesting read.
A great fanfiction concept could be centered around Team Natsu getting magically separated. Natsu ends up in a realm where there's no fire magic, and he has to learn to adapt and find a way back to his friends. Gray could be in a world of eternal ice and has to find a way to break free. Lucy might be in a place where celestial spirits are feared and hunted, and she has to protect them while trying to reunite with the team.
One idea could be exploring Natsu's struggle to control his dragonized form. Maybe he accidentally dragonizes at an inopportune time and has to deal with the consequences, like scaring his friends or causing destruction. Another could be a scenario where he dragonizes to save the guild from an extremely powerful enemy that no one else could defeat.
