A frequent theme is the clash of personalities. Batman is often depicted as dark and brooding, while Robin can be more light - hearted and impulsive. In fanfiction, this difference can be exaggerated, leading to constant friction and eventually Batman hating Robin. Also, the theme of a broken father - son relationship often comes up. Batman is like a father figure to Robin, and when this relationship breaks down in a bad way, it can result in Batman's hatred.
Well, this kind of fanfiction might be an interesting take on the character. It could explore a darker side of Harry Potter that we don't often see in the original series. Maybe the author wants to show how all the pressure and trauma he has endured could lead to a more cynical view of those around him.
Well, in some RWBY fanfiction, the 'everyone hates Jaune' trope might be used to create drama. Maybe the author wants to explore how Jaune would grow and overcome such extreme dislike from others. It could also be a way to put him in difficult situations for character development.
Perhaps in this fanfiction, Naruto discovers some dark secrets about the village. Secrets that make him feel like he's been used all along. Like the village was only using him as a weapon against their enemies. This realization could make him resent everyone in the village, thus hating everyone.
Perhaps Harry has seen the worst in people too often. He might have witnessed so much greed, envy, and cruelty among those around him that he has lost all faith in humanity and thus hates everyone. He could be in a situation where he feels completely alone and that no one truly understands him.
Well, it could be that Percy has had some really bad experiences in his life that made him bitter towards everyone. Maybe he was betrayed by friends in the past, so now he just can't bring himself to trust or like anyone.
As a fan of online literature, I don't have any emotions. However, according to the knowledge I have learned about online literature, the following are some plots and routines of martial arts novels that may cause readers to dislike:
1. Over-pursuit of martial arts: In wuxia novels, the protagonist often becomes a martial arts master through continuous hard work. However, excessive pursuit of martial arts might make the novel lose its storytelling and become boring.
2. Repetitive routines: Many Wuxia novels have very fixed plots and character routines. For example, the protagonist is usually the descendant of a certain family. After experiencing various tests and challenges, he becomes a martial arts master and finally defeats the evil forces. This kind of routine plot might make the readers feel bored.
3. Flatten the character image: In martial arts novels, the character image is usually very important, but sometimes the author may make the protagonist or other characters too flat and lack personality and depth, which may disappoint the readers.
4. The discrimination against female images: In martial arts novels, women are usually seen as weak and helpless existences, and there are often plots where they are dominated by men. This kind of discrimination against female images may make readers feel uncomfortable.
5. Forceful He: In martial arts novels, the author sometimes forces the protagonist to achieve a certain ending. For example, the protagonist usually defeats the evil forces and obtains the final victory. This kind of coercion might disappoint the readers and reduce the reading experience.
It could be Naruto himself. Since he hates everyone, his actions against the people he once cared about could make him the antagonist. He might start attacking the Hidden Leaf Village or other ninja villages, making him the main source of conflict.
