Maybe in some fanfics, the author wants to create a new and controversial plot. They might make Percy hate Annabeth due to some misunderstandings, like a miscommunication about a quest or Percy believing Annabeth has betrayed him in some way.
In some fanfics, the author might be trying to break away from the traditional relationship between Percy and Annabeth. By having Percy hate Annabeth, they can introduce new love interests for both characters and explore different relationship dynamics. This can lead to some really interesting and unexpected plot twists.
Maybe in some fanfictions, the writers change the characters' personalities too much. Annabeth is a strong - willed character, and if Percy is portrayed in a way that goes against their original relationship dynamic, she might seem to 'hate' him in that fictional context.
It could be that the fanfiction plots are so convoluted. For example, the writer might create some really out - of - character situations for Percy and Annabeth. If Percy is constantly put in scenarios where he's made to be at odds with Annabeth in ways that don't feel true to the original series, it could give the impression that he hates her in the fanfiction.
Perhaps in this high school fanfiction setting, Percy has a different group of friends who don't like Annabeth. Their influence on Percy gradually makes him develop a dislike for her. You know, peer pressure can sometimes change a person's attitude towards others.
It could be that the way the child is written in the fanfiction goes against Annabeth's character. For example, if the child is depicted as being overly needy or bratty and Annabeth, who values independence and order, just can't stand it. Also, it might be that the existence of the child changes Percy in a way that Annabeth doesn't like. Like Percy starts to neglect her in favor of the child.
Perhaps Annabeth's dad has some old - fashioned ideas. He might believe that Percy doesn't have the right qualities to be with his daughter. He could also be jealous in a way. Percy is an important person in Annabeth's life and her dad might feel left out or that Percy is taking his place in a sense.
Maybe they have a different taste in literature. They might prefer other types of stories and not be into the fanfiction genre, especially those related to Percy and Annabeth.
Maybe in the fanfic, Percy has some actions or characteristics that Nico doesn't like. For example, Percy might be too self - centered in the story, which goes against Nico's values. Or perhaps Percy has something that Nico desires, like more popularity or a closer relationship with a certain character, and that envy turns into hatred in the context of the fanfic.
It could be that the author of the fanfic has created a rivalry between them. In some fanfics, authors like to add tension and conflict, and Jason hating Percy could be part of that. Maybe Percy got more attention or praise in the story, and Jason, being a proud character, resents that.
It could be that Percy's arrival disrupts the balance or routine at camp, which Annabeth doesn't like. Or perhaps there's some jealousy or competition involved.
Maybe Nico has his own view of the characters. He might think that the 'nicecery' in the fanfic distorts the real relationship or personalities of the characters, so he hates it.
