His relationship with Lucy might become more protective. Since he's now more vulnerable with one arm, Lucy might feel the need to be stronger to protect him as well, which could strengthen their bond in a different way.
Natsu's relationship with Gray could also change. Gray might initially be overprotective of Natsu, not wanting him to get into dangerous situations. But Natsu, being Natsu, would want to prove that he's still capable. This could lead to some friendly arguments and also a deeper understanding of each other's characters as they deal with this new situation.
His relationship with Lucy would be interesting. If reborn, Natsu might be more protective of Lucy from the start. He could also share his past life memories with her, which would deepen their bond even more. They might start going on adventures together even earlier in the story.
One possible plot twist could be that Natsu's one - arm state makes him struggle with his magic at first. But this leads to him discovering a new, more powerful and unique form of his magic that he wouldn't have found otherwise. For example, he might have to rely more on his fire control skills rather than brute strength in battles.
Well, Natsu's relationship with Gajeel could be really different. Gajeel might be more respectful towards Natsu as a girl, or he could be more competitive in a different way, like trying to prove that he's the better dragon slayer in a more gentlemanly manner. Natsu's relationship with the guild master, Makarov, would also change. Makarov might be more protective of Natsu as a girl, and Natsu might have to fight harder to be taken seriously in guild matters. In general, all of Natsu's relationships would be reshaped, with new levels of complexity and humor added to the story.
Lucy and Natsu's relationship could become more intense. In some fanfictions, their bond might develop into a deeper romantic connection, which would change how they interact. Gray might become more of a rival, feeling like Natsu is getting more attention in these fictional scenarios.
Well, if Natsu had the Sharingan in a fanfiction, it would likely enhance his combat abilities significantly. He could predict his opponents' moves more accurately, similar to how Sasuke uses it in Naruto. This would make him even more formidable in battles against strong foes in the Fairy Tail world. Maybe he could use it to analyze magic spells and find their weaknesses faster.
The story would have to shift its focus. Instead of relying on Natsu's dragon - slayer magic and Mirajane's take - over magic, new characters or existing ones would need to shine. This could open up new plotlines such as the discovery of new magic among the remaining members or the forging of new alliances outside of the guild to compensate for the loss of Natsu and Mirajane. It would be a major turning point in the fanfiction's narrative.
Their relationship would likely become more intimate and deeper. With a baby on the way, they'd have to rely on each other more. Natsu would probably become more gentle and caring towards Mirajane, and Mirajane would feel more protected by Natsu.
The relationships might become more relaxed. For example, characters who are usually a bit reserved like Levy might be more open and friendly with others. Gray and Natsu, who often bicker, could end up laughing together over some drunken joke. And Lucy might be more affectionate towards her friends, giving hugs more freely.
In fanfictions, Natsu's anger often has a significant impact on his relationships. His anger towards enemies unites him more closely with his Fairy Tail comrades. They see his passion and are inspired to fight alongside him. However, his anger can also create misunderstandings. For example, if he gets angry at a new member of the guild who made a mistake but was actually trying to help, it could make that person feel unwelcome at first. Overall, his anger is a double - edged sword in his relationships.
If Natsu goes back in time, his relationships would be very different. With his friends, he might have a new level of understanding. For example, he could see how they grew up and the challenges they faced in the past. He might be more protective of them, especially if he knows what's going to happen in the future. His relationship with Lucy could also change. He could see her in a new light, perhaps realizing things about her that he didn't before when he first met her in the present.
