In fanfiction, Naruto might be hated by his friends if he makes a big decision that goes against their group's values. For example, if he aligns with an enemy for what he believes is a greater good but his friends don't understand his motives. Or perhaps a new character is introduced who manipulates the situation and turns his friends against him by spreading lies and half - truths about Naruto. Sometimes, the writer just wants to explore a different and darker side of the Naruto universe, so they create a scenario where his friends turn on him.
One possible reason could be envy. If Naruto suddenly gains a great deal of power or attention in the fanfiction, his friends might feel left out or jealous. Another reason could be a misunderstanding. Maybe Naruto is framed for something he didn't do, and his friends believe the false accusations without giving him a chance to explain. Also, in some fanfiction, a change in Naruto's personality, like becoming overly aggressive or secretive, could lead to his friends growing to dislike him.
In some fanfictions, Naruto might be hated by his friends due to a misunderstanding. For example, if there's a false rumor spread about him being a traitor. Another reason could be his sudden increase in power that makes his friends jealous. Maybe he accidentally harms one of them during a training session and they hold a grudge.
In some fanfictions, it could be due to outside influence. For example, an enemy might use some kind of mind - control or false information to make Naruto's friends turn against him. Also, Naruto's own actions that are misinterpreted can lead to this. Say he tries to protect his friends in a way that seems wrong to them at first glance, like using a dangerous jutsu near them to fend off an attack.
One possible reason could be a very different and perhaps unappealing take on Naruto's character in that fanfiction. Maybe the author made him overly cruel or out of character in ways that fans who love the original Naruto can't stand.
One possible reason could be a false accusation. Maybe someone spread a rumor that Naruto was involved in a heinous act, and without proper investigation, everyone turned against him.
One reason could be his power. His connection to the Nine - Tails makes him extremely powerful. In fanfiction, some in Konoha might fear this power and thus hate him. Another reason could be jealousy. Naruto becomes very popular and respected in the original story. But in fanfiction, some characters might be jealous of his achievements and turn that into hatred.
Maybe in that fanfiction, Naruto's over - eagerness to be recognized could be misconstrued. His loud and boisterous nature might annoy people. For example, if he constantly interrupted others or pushed his ideas too hard without considering others' feelings, it could lead to dislike.
He could start by having an honest conversation with his friends. Explain his side of the story clearly. For example, if it was a misunderstanding, he can show evidence to clear his name.
Another reason might be related to a past event that Naruto unknowingly caused harm to one of the Team 7 members' families. Even if it was an accident, the emotional pain could make the affected member, and maybe the whole team, hold a grudge against Naruto. For instance, if Naruto's actions during a battle led to the destruction of a family's home, and a Team 7 member was from that family.
At first, Naruto might be really confused. He's used to thinking of his friends as his support system, so when they turn on him, he doesn't understand why. He'll probably try to talk to them, to ask what he did wrong. If they don't listen, he could become really sad and withdrawn. Maybe he'll start training even harder, using the pain of being rejected by his friends as motivation to become stronger.
One reason could be that some fans might be disappointed with certain aspects of the original Naruto series. For example, the development of some characters might not meet their expectations. So, they create fanfiction to express their negative feelings.
