One reason could be that Naruto is a character with his own identity and goals. If the fanfiction keeps putting him in situations that are not in line with his character arc, such as making him abandon his dreams for the sake of Team 7 in a way that doesn't make sense, he would have enough. Fanfiction writers sometimes go overboard with their creativity and end up straying too far from what Naruto is really about.
Well, 'naruto has had enough fanfic' might imply that the Naruto universe has been so overly explored in fan - created fictional works. There could be various reasons for this. For instance, with the large number of fanfics, the quality might be diluted, and the original essence of Naruto might be getting distorted in some of these fan - made stories. Also, it could be that the fans themselves feel there are just too many fanfics, and it's taking away from the uniqueness of the official Naruto storylines.
Perhaps it means that Naruto has reached a point where he's sick of the various fanfiction scenarios involving Team 7. Fanfiction can range from alternate universes to different relationship dynamics within the team. If there's an overabundance of a particular type of story, like ones that always make Naruto the underdog in a way he doesn't see himself, he might feel like he's had enough.
They might feel that the flood of fanfic is diluting the true nature of the Naruto story. There are so many different interpretations in fanfics that it could be confusing or detracting from the core of what Naruto is all about. Also, if someone is more of a purist about the original Naruto series, seeing so much fan - made stuff might make them feel that enough is enough.
It could be some of the younger ninjas from the village who look up to Naruto. Maybe a young genin who has a special ability with earth jutsu, and another who is really good at stealth but lacks confidence. Naruto would then help them grow.
One implication is that it could lead to a decrease in the popularity of Naruto fanfiction in general. If the general sentiment is that there's enough, fewer people might be interested in creating or reading new fanfictions.
The team dynamics would be quite unique. There would be a lot of self - competition. Each Naruto would be trying to outdo the other in terms of strength, speed, and ninjutsu. But at the same time, they would also understand each other deeply since they are the same person. They might have an unspoken agreement to push each other to be better.
Well, Naruto would be like a catalyst for change in the team dynamics. He'd bring his unique sense of humor and determination. This would rub off on the others. He could help Obito see the value in the team more clearly. With Kakashi, he could show him that it's okay to rely on others. And for Minato, Naruto could be a source of pride and motivation. His presence would create a more family - like atmosphere within the team, which would make them fight even harder for each other.
His old team would be Sasuke, Sakura, and Kakashi. They are the main characters associated with Naruto's early team experiences. In the context of this fanfic where they die, it's likely to have a huge impact on Naruto and the overall story.
In the fanfic, Naruto could hate Team 7 because of a change in the story's plot. Perhaps something bad happened that he blames on the team. It might be that the team made a decision that Naruto strongly disagreed with, like a mission choice or how they treated an enemy. This could cause his feelings towards them to turn sour.
