Well, in certain fanfiction stories, Naruto may hate the Third Hokage due to the way the Hokage handled the Uchiha situation. Since Naruto has friends like Sasuke who are Uchiha, he might resent the Third Hokage for not preventing the downfall of the Uchiha clan, which in turn affected Sasuke deeply. And he may see this as a sign of the Third Hokage's incompetence or lack of real care for the village's well - being as a whole.
Naruto would probably be extremely hurt. He has always looked up to the Third Hokage as a grandfather figure. So, initially, he would be in denial, thinking there must be some misunderstanding.
The Third Hokage's training might have introduced Naruto to more advanced jutsus. For example, he could have taught Naruto better control over his chakra, which is crucial for performing ninjutsu. This would allow Naruto to use his Rasengan more effectively and with less strain.
One challenge could be mastering difficult jutsus. The Third Hokage might set high standards for Naruto to learn complex techniques, which would be a struggle for him.
Another aspect could be related to past traumas. Naruto has been through a lot, and if the Konoha 11, even unintentionally, reminded him of some of the negative experiences he had in Konoha, like the ostracism he faced as a child, it could make him hate them in the fanfiction.
In some fanfiction, Naruto might be depicted as hating toads because the author wants to explore an alternative personality or backstory for him. Maybe they want to show a more rebellious side of Naruto who resents the toads for their role in his training or for the demands they place on him.
One reason could be that Minato values the original narrative and the way his story was intended to be told. Fanfiction can sometimes introduce elements that he might find inappropriate or not in line with the values and themes of the Naruto world. For example, some fanfictions might create overly dramatic or out - of - character scenarios for him, which he would not approve of.
In fanfiction, Naruto could hate Sakura due to her treatment of him. She often overlooked his feelings in the original series. Fanfic authors might exaggerate this aspect. For example, if Sakura continuously dismisses Naruto's achievements or makes him feel inferior, it can build up to a strong dislike or hatred in the fan - created stories. Also, some fanfictions might explore a darker side of Naruto where his pent - up emotions turn into hatred for Sakura, perhaps as a way to show his growth into a more complex character with a wider range of emotions than just the positive ones shown in the original anime.
It could be that in the fanfiction, there are made - up events that lead Naruto to hate Minato. For instance, if there is a plot where Minato was thought to have some dark secrets that affected Naruto's life badly, like being involved in some sort of conspiracy against Naruto without his knowledge. This would give a reason for Naruto to hate him.
Some fanfictions might portray Naruto hating Team 7 because of a clash of ideals. Naruto has his own beliefs and goals, and if the other members of Team 7 constantly oppose or undermine those in the fanfic, it could cause him to develop a dislike and eventually hatred towards them. Also, if there are issues with power dynamics within the team, like if Naruto feels overpowered or bullied by the others, that could contribute to his hatred as well.
It could be because of the way the Leaf treated his family. Maybe in the fanfiction, new revelations come to light about how the Leaf was involved in some negative things regarding his parents. So Naruto, out of anger and disappointment, hates the Leaf.
