His relationship with Jiraiya could be affected. Jiraiya has a strong connection with the toads, and if Naruto hates toads, it could create a rift between him and his mentor. This could lead to Naruto losing an important source of guidance and support in the fanfiction.
The balance of power in the Hidden Leaf Village could be disrupted. Naruto's power is often linked to the toads. If he turns against them, it could leave the village vulnerable to threats as Naruto may not be as effective in battles without the toad - related abilities. Also, it could lead to internal conflicts within the village as different factions may have different opinions on Naruto's new stance towards the toads.
One consequence could be that he leaves the village. He might go off on his own to find a new place where he feels accepted and can start anew.
It could also lead to some division among the Naruto fandom. Those who support Sakura's view might be more critical of fanfiction, while those who love fanfiction might not like Sakura as much because of her stance. For example, in online Naruto communities, there could be debates and arguments about whether Sakura is right to hate fanfiction.
One possible consequence could be that his relationships with other characters who are related to the Uzamaki clan, like Hinata (since she marries into the Uzamaki family), become strained. It might also lead to internal conflict within himself as he battles with his own identity and heritage.
One consequence could be that Naruto leaves the village. He might go on a journey alone, seeking a new purpose away from the place that has caused him so much pain. This would be a major change from his original story where he was so attached to the village.
It could also lead to a divergence from the core values of the Naruto series. The series often emphasizes family, friendship, and love in a positive way. If Naruto hates his family in fanfiction, it goes against these values and may cause some fans to be disappointed.
Naruto's hatred for the world in fanfiction might also lead to a change in his powers. His negative emotions could either make him lose control of his existing powers or lead to the development of new, more dangerous powers that are fueled by his hatred. This would pose a great threat not only to his enemies but also to those he once considered friends.
One consequence could be that it divides the fan community. Fans who like Jason might not appreciate Percy being portrayed as hating him, and vice versa. This could lead to arguments and a split in the fandom.
One consequence could be that he might face social isolation in certain situations. For example, in a party or gathering where alcohol is the main feature, Percy would be the odd one out, which could lead to him being excluded from certain social circles within the fanfiction.
One consequence could be that Harry becomes more isolated. If he hates the Order, he may distance himself from them, which means he loses a group of potential allies. This could put him in a more vulnerable position in the wizarding world.
The consequence could be that the fanfiction community might feel less connected to Minato as a character. Since he is a significant part of the Naruto universe, his dislike of fanfiction could make some fans less enthusiastic about including him in their fan - created stories. This might lead to a shift in the focus of fanfiction towards other characters who are more 'welcoming' of fan interpretations.
