In a fanfiction, an emotionless Naruto in Fairy Tail might have his own unique fighting style. Since he doesn't rely on emotions like anger or excitement to power up, he could have a more calculated and precise style. He might study the magic of Fairy Tail and use it in a way that no one expects. His lack of emotion could also make him a better strategist as he's not influenced by things like fear or overconfidence.
It could work by making Naruto a more mysterious and brooding character. In Fairy Tail, there are many characters with different personalities. An emotionless Naruto would stand out. He might be more focused on achieving his goals without being distracted by emotions. For example, he could be on a mission to find a way back to his own world and his lack of emotion helps him stay determined.
One possible plot could be that Naruto is transported to the Fairy Tail world and is somehow stripped of his emotions during the process. The Fairy Tail wizards then have to figure out how to send him back while also trying to restore his emotions. Along the way, Naruto's lack of emotion might cause him to make some uncharacteristic decisions that put everyone in danger.
In a Naruto - Fairy Tail fanfiction where Naruto is a brother figure, he might bring a whole new dynamic. He could teach the Fairy Tail guild members some of his ninja training techniques. For example, how to better endure pain or how to focus their energy more effectively. Also, his backstory of being an outcast in his own village at first could make him relate to some of the Fairy Tail characters who have had difficult pasts.
Well, one way it could work is if there was some sort of multiverse crossover. Maybe in a strange twist of magic, Naruto could be transported to the Fairy Tail universe and end up related to Mavis. It would be really interesting to see Naruto's ninja skills combined with the magic of Fairy Tail. He could teach the Fairy Tail guild some unique combat techniques.
It might be that in this fanfiction, the writer wants to explore a different side of Naruto. By making him emotionless, they can create unique interactions with the Fairy Tail characters. For example, his lack of emotion could contrast sharply with Natsu's fiery personality, leading to interesting story developments.
One possibility could be that a main character, perhaps Natsu, is somehow reborn without emotions. He would then go through the world of Fairy Tail in a very different way. For example, he might not be as eager to fight for his friends because he doesn't feel the passion or loyalty he once did. This could lead to a lot of conflict within the guild as they try to figure out how to bring back the old Natsu.
His role could be that of a teacher. Since he doesn't have emotions clouding his judgment, he could teach the Fairy Tail members about self - control and the importance of thinking rationally. He could show them how to use their magic more effectively without being carried away by emotions like anger or pride. He might also introduce them to some ninja techniques that are based on discipline rather than raw emotion.
Natsu could be a great choice. He's a central figure in Fairy Tail. His usually fiery and passionate personality being replaced with an emotionless state would create a lot of contrast and interesting storylines. The guild members would be shocked to see him so different, and his lack of emotion could also affect his relationship with Happy.
A crossover could also involve a Fairy Tail mage somehow getting access to the powers of the Quake - Quake Fruit. They could incorporate it into their magic. Maybe a Fairy Tail character is on a mission in a world similar to Naruto's and discovers the fruit. With their new - found power, they return to the Fairy Tail world and use it in battles against other mages or threats. The different magical elements in Fairy Tail and the unique abilities of the fruit would create interesting combinations.
Well, for it to work, the Naruto character with Ice Dragon Slayer powers could bring a new dynamic to Fairy Tail. He could use his unique jutsu combined with dragon slayer magic. For example, he might use shadow clones to perform multiple ice attacks at once, like an army of ice dragon slayers. This would add a new level of strategy to the Fairy Tail battles.
Naruto could save Fairy Tail in fanfiction through his strong will and never - give - up attitude. He has faced numerous challenges in his own world and emerged victorious. In the Fairy Tail universe, he could inspire the members of the guild to keep fighting even when all seems lost. He might teach them some of his ninja techniques which could give them an edge in battles. His experience in dealing with powerful and dangerous opponents would be invaluable in protecting Fairy Tail.
