Well, it could be because of some sort of poison or a genjutsu in the fanfiction. Maybe an enemy manages to use a special poison that slowly weakens Naruto until he finally faints. Or a very powerful genjutsu that messes with his mind so much that his body shuts down and he faints.
In some Naruto fanfictions, Naruto might faint due to overusing his chakra. For example, if he pushes himself too hard in a battle, like when he tries to use a new and extremely powerful jutsu without fully mastering it. His body can't handle the excessive chakra drain, and he faints as a result.
In some fanfictions, Naruto might be made to hate his mother because of a misinterpreted prophecy or a false belief that she abandoned him. Maybe the author wants to create a more complex and angsty story line for Naruto.
Maybe he's under extreme stress and feels hopeless, like facing impossible challenges or losing someone dear.
A simple reason could be that they are poisoned. An enemy might have laced their food or drink with a slow - acting poison that causes them to faint at an unexpected moment.
Maybe he's running away from the pressure in the village. There are always high expectations on him, and he might feel suffocated and need some time alone to figure things out.
Perhaps in the fanfiction world, Naruto has other relationships or commitments that make him avoid Sakura. For example, he could have made new friends or allies who don't get along well with Sakura, so to keep the peace or not get involved in drama, he stays away from her.
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.
Maybe he hates it because it often distorts the real ninja world he knows. Fanfictions might create false or out - of - character scenarios that he can't stand.
In some fanfictions, Naruto might avoid Sasuke because of a misunderstanding. For example, if there is a false rumor spread about Sasuke being involved in something bad, Naruto could be misled and keep his distance.
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.
Well, Naruto is a very popular anime. Everyone loves it. Fanfiction based on it gives people a chance to be creative. They can continue the story in their own way, or even change some parts they didn't like in the original. It's like building on a well - loved foundation.
