Another option could be a dark wizard from the past who was once defeated by the founders of Fairy Tail. But Natsu's time - traveling causes some sort of ripple effect that brings this wizard back to power. He then wants to take revenge on the guild and sees Natsu as a symbol of the future that he wants to destroy.
Well, in this kind of fanfiction, Natsu might use his knowledge of the future to prevent some tragedies. For example, he could stop certain battles from happening or save characters who died in the original timeline. Maybe he would also try to change the power dynamics within the guild earlier on, making Fairy Tail even stronger from the start.
A plot could involve Natsu going back in time to a time of great danger for the guild, a threat that was previously unknown in the present. He has to use his present - day skills and knowledge to fight this threat. But he also discovers some secrets about the guild's founders and their powers that were lost over time. This knowledge could be crucial in not only saving the past but also making the present - day Fairy Tail even stronger.
Yes, in a lot of Fairy Tail fanfiction, Natsu can be overpowered. Writers often like to amp up his powers for more exciting storylines. For example, they might give him new fire - based abilities or make his existing ones even stronger to defeat more powerful foes.
In fanfiction, Natsu's age can vary greatly. Some authors might keep him at his canonical age from the original Fairy Tail series, which is around 17 - 18 years old at the start. However, in alternate universe fanfictions, he could be older or younger depending on the plot. For example, in a time - travel based fanfic, he could be much older if the story takes place far into the future or much younger if it goes back to his childhood days.
One great time travel fanfiction in the Fairy Tail universe could be 'Time's Twist'. In this story, Natsu and Wendy are sent back in time and have to figure out how to get back. It has really interesting character interactions, especially when they meet younger versions of their guild mates. They also have to deal with the threat that caused the time travel in the first place, which adds a lot of excitement to the plot.
One possible aspect of a Fairy Tail Natsu and Tartaros fanfiction could be Natsu's battle against the powerful foes in Tartaros. He might face new and terrifying enemies that test his limits. His dragon slayer magic would be put to the extreme, and perhaps he discovers new powers along the way.
In fanfictions like this, the character development of Natsu within the context of Sabertooth is interesting. He could learn new magic techniques from them or teach them his own unique brand of Fairy Tail spirit. It might also explore how the different cultures of the two guilds clash or blend.
One great fanfiction that delves into Natsu's memories might be titled 'Natsu's Hidden Past'. In it, the author could explore his early days in Fairy Tail, his relationship with Igneel, and how those experiences shaped the person he is today. It might show how he learned to control his dragon slayer magic and the friendships he formed along the way.
There might be. 'Fairy Tail' has a large fan base, and many fans enjoy creating fanfiction. Natsu, with his fiery personality and combat skills, could be an interesting Mandalorian in a fan - made story. It would be cool to see how his magic would interact with the Mandalorian technology and culture. However, I'm not sure exactly how many of such fanfictions exist, but it's definitely a concept that could work well.
