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.
In this fanfiction, it might be that Naruto's rapid rise in power made others jealous. People who were once his friends or comrades could start to hate him out of envy. His newfound strength could make them feel inferior, and instead of being happy for him, they choose to hate him.
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.
Maybe in the fanfiction, Naruto has made some decisions that go against Hinata's beliefs or values. Suppose Naruto decides to use a very dangerous and unethical jutsu for power, and Hinata, who is usually very moral, might start to hate him for that.
One possible reason could be misunderstandings. Naruto is a bit of an outcast at first, and his brash personality can be misinterpreted. In fanfiction, the team may misjudge his actions as being self - centered when in fact he's just trying to prove himself. This could lead to them hating him.
He could try to fight back against this hatred. Naruto has a strong will. Instead of just accepting being hated, he might try to prove everyone wrong. He could start by doing good deeds secretly or try to expose any false rumors that are causing people to hate him.
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 possible reason could be the difference in power systems. Naruto's world has its own unique ninja abilities like jutsus, while Fairy Tail has magic. In some fanfictions, the clash of these two different power concepts might make Fairy Tail fans dislike Naruto being involved. Maybe they think Naruto's abilities are too overpowered or not in line with the magic - based universe of Fairy Tail.
In some fanfictions, Naruto might be depicted as being hated by Konoha. This could be due to various reasons. Some authors might want to explore alternative storylines where the village's perception of Naruto is different. For example, they could write a story where Naruto's power is seen as a threat rather than an asset, leading to hatred from some in Konoha.
His character development would likely be stunted in terms of his social skills. In the original series, Naruto grows through his relationships. But if everyone hates him, he may not have the opportunity to learn empathy and understanding from others. He might focus more on self - preservation and become more self - centered as a result.
He might try to prove himself. Naruto has always been a determined character. So he would likely strive to show his family that they are wrong about him. He could do this by achieving great things in the ninja world, like mastering new jutsus or completing difficult missions.
In fanfiction where Naruto is hated by his family, it could be a very dark and angsty take. Maybe the author wants to explore the idea of Naruto facing even more hardships on top of being an outcast in the village. It could lead to a very different Naruto, one who is perhaps more bitter or desperate for acceptance outside of his family unit.
