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.
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.
It can create a lot of negative buzz within the community. Fans who are passionate about Naruto might be really vocal about their dislike for such fanfiction, which could lead to some arguments or debates among fans who have different opinions on whether it's acceptable or not.
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.
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.
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 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.
Another theme could be rewriting the plot to be more of a tragedy. Instead of the hopeful and positive story in the original, the fanfiction might make everything go wrong for the characters. For example, Konoha could be destroyed and the characters could be left with no hope.
