There might be a fanfiction where Natsu teams up with unexpected characters inside the Tower of Heaven. For example, he could form an alliance with a group of minor villains who have a change of heart and they all work together to face a greater evil within the tower. In this type of story, there would be a lot of character development as they learn to trust each other.
One interesting fanfiction could be one where Natsu discovers a hidden power within the Tower of Heaven. Maybe he finds a magical artifact that enhances his fire magic in ways he never thought possible.
One interesting concept could be exploring the backstories of the characters involved in the Tower of Heaven arc more deeply. For example, delving into Jellal's internal struggles before his fall to the dark side in a way that the original series might not have fully explored. Another concept could be creating alternate endings to the Tower of Heaven events, like what if Erza and the others had failed to stop the tower's activation? It could also be about exploring new relationships between the characters during that time period, such as how different characters might have interacted if they had been paired up differently during the battles in the tower.
A great Natsu and Lucy fanfiction might involve a time - travel plot. For example, they could go back in time to the founding of Fairy Tail. This would give them a chance to meet the original members and change the course of history. Along the way, their relationship would surely evolve as they face the challenges of the past. It's a really cool concept that many fanfiction writers like to explore.
One interesting 'Fairy Tail' female Natsu fanfiction could be the ones where Natsu is reimagined as a female in a different adventure. For example, she might go on a quest to find a long - lost magical item that was hidden by an ancient wizard. Another could be a fanfiction where female Natsu has to team up with other Fairy Tail members in a new way to defeat a powerful dark guild. There are also fanfictions that focus on female Natsu's relationships with other characters like Gray or Lucy in a more romantic or platonic way.
One interesting Lucy x Natsu fanfiction could be 'A Bond Beyond Magic'. In this fanfic, Lucy and Natsu go on a journey to a hidden magical realm where they have to rely on their bond more than ever. Their relationship deepens as they face challenges that test not only their magic but also their feelings for each other.
One interesting fanfiction could be where Natsu is left behind in a dangerous, uncharted land. He has to rely on his wits and his unique magic skills to survive and find his way back to the guild. In this kind of story, he might encounter new and strange magical creatures, and have to form unexpected alliances.
Create an engaging plot. You could start with a problem like Natsu getting separated from his guildmates in the Tower of Heaven. Then, introduce new challenges and characters as he tries to find his way out. Maybe he has to face a series of magical traps or encounter a powerful enemy that is guarding a secret within the tower. Also, add some emotional depth. For example, Natsu could be haunted by memories of his past related to the tower, which would add more layers to the story.
One common plotline could be Natsu going on a solo adventure that the other Fairy Tail members watch through some magical means. Maybe he discovers a new type of magic that is both dangerous and alluring. Another could be Natsu facing a version of himself from an alternate timeline, and the guild watches as he battles his other self to save the world.
One popular 'Fairy Tail Natsu Banished' fanfiction might be 'Away from Home'. It explores Natsu's journey after being banished and how he overcomes various challenges on his own. He meets new characters and discovers new powers along the way.
Often, it could be because of a false accusation. Maybe someone framed Natsu for a crime he didn't commit, like stealing a powerful magical artifact from the guild. So, to maintain peace and order, the guild leaders had no choice but to banish him.
Well, a great plot point could be the exploration of Natsu's past as END. Maybe in the fanfiction, it's revealed that there are certain memories or prophecies related to his identity as END that he has to face. Also, his relationship with Gray could be really interesting. Since Gray has his own battles against demons, how he and Natsu interact when Natsu is fully embracing his END side could be full of drama. Additionally, the guild's reaction to Natsu's true form could lead to internal conflicts or a strengthening of their unity as they face the challenges that come with it.
