Spike might hate Twilight fanfiction because he doesn't like the way some writers take creative liberties. He may think that they are misinterpreting Twilight's essence. In many fanfictions, the relationships and events are twisted, and Spike, being close to Twilight, might feel protective of her true nature and thus dislike these fictional interpretations.
Maybe Tails hates fanfiction because it often goes against the original vision of the character. Fanfictions might portray him in ways that he doesn't like or in situations that are inconsistent with the official story.
Some might hate it because the writing style doesn't appeal to them. Maybe it's too flowery or not descriptive enough. Also, if the characterization of Alice in the fanfiction is off from what they expect in the Twilight series, that could be a reason.
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.
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.
Well, perhaps yoh has had some bad experiences with human fanfiction in the past. Maybe yoh read some really poor - quality ones that were full of clichés or had terrible writing. Or it could be that yoh simply prefers other forms of literature or storytelling over human fanfiction. There are so many different types of creative works out there, and yoh might just be more drawn to non - fanfiction works that deal with humans in a more 'original' way, like classic novels or biographies.
Maybe he thinks it distorts the real story of the Avengers. Fanfiction often takes the original story and characters in unexpected directions, which might not sit well with him.
Maybe Ash has a particular view of his own character and the way Cynthia is portrayed in fanfiction doesn't align with his idea. He might feel that the fanfiction distorts their characters or the relationship between them in some way.
Well, in some fanfictions, Hermione might hate Bella because their personalities are so different. Hermione is studious, logical, and a fighter for justice. Bella, on the other hand, is often portrayed as more passive and overly focused on her romantic relationships. Their different values and ways of approaching life could lead to Hermione's dislike of her in fanfiction.
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.
