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.
Well, Nico has his own complex personality and backstory. In the original story, his relationship with Percy is multifaceted. The nicecery fanfic might simplify or misinterpret this relationship. Nico may feel that it doesn't do justice to the real depth and nuances of their connection. He could also be protective of the original story's integrity and see the fanfic as a deviation that he cannot abide. It's like when you have a favorite book or movie, and someone creates a fan - made version that completely changes the essence of it. Nico might be having a similar reaction to this Percy nicecery fanfic.
It could be that Nico has a very specific understanding of Percy. The fanfic might go against what he believes is the right way to portray Percy, thus leading to his dislike. For example, if the fanfic makes Percy overly nice in a way that seems out of character, Nico, who has a deep connection with Percy in the original story, may not be able to accept it. Also, perhaps Nico doesn't like the general style or tone of the nicecery fanfic. It might be too sugary or idealized for his taste.
The writer could try to stay more true to the original characters' personalities. If the fanfic respects the core of Nico and Percy's relationship as it is in the original, Nico might not hate it.
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.
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.
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.
Jason Grace may have had some bad experiences with Percy Jackson fanfics. For example, he might have read some that were really poorly written, with inconsistent plots or offensive content. This could have led him to form a general dislike for all Percy Jackson fanfics.
Well, perhaps in fanfiction, their characters are often misrepresented. Maybe Percy's personality traits are distorted in a way that makes him seem out of character when paired with Jason, which could lead to Percy seeming to 'hate' Jason in those stories.
Maybe Frederick has a different view of the original work and thinks fanfiction distorts it. For example, if he is a purist who loves the original Percy story as it is, any fan - made alterations in the fanfiction might be off - putting to him.
Well, it could be that in the fanfiction, Zeus's actions towards Percy's friends or family were not good. For example, if Zeus endangered them or was overly harsh. Percy is a character who values loyalty and justice, so he would hate Zeus for acting against those values.
Maybe Percy has had bad experiences related to alcohol in the fanfiction world. For example, he could have seen someone he cares about become a different, worse person because of alcohol. Or perhaps it goes against his values. He might be a character who values self - control and discipline, and alcohol represents the opposite of that.
In fanfiction, Percy could hate the gods due to their lack of proper care for their demigod children. They are often absent and don't really step in to help when the demigods are facing real hardships. For example, Percy has been through numerous life - threatening quests where the gods could have made things easier but didn't. This builds up resentment towards them.
