It could be that their goals and ways of achieving them are so different that Ash starts to dislike Dawn. In the fanfic, perhaps Dawn's actions end up interfering with Ash's plans more often than not.
There could be a conflict over Pokémon training methods. Ash has his own unique way of training his Pokémon, and if Dawn's methods are very different and she tries to impose them on Ash or something similar, it might lead to Ash hating her.
Maybe Ash has some misunderstandings about Dawn. For example, he might think Dawn is too competitive and it makes him uncomfortable.
Yes, there might be such fanfics out there. Fanfic writers often explore different character relationships and emotions. They might create scenarios where Ash has some sort of dislike for Dawn, perhaps due to differences in their goals, personalities, or how they interact with Pokemon. It could be an interesting take on the Pokemon universe, but it's important to note that these are non - canonical interpretations.
Well, they could start to communicate more. If Dawn realizes that Ash dislikes her and tries to have an open conversation with him, things might change.
The writer might be trying to add some drama to the story. By making Aang hate Katara, it creates a conflict that can drive the plot forward. For instance, their friends might have to work hard to resolve this hatred and restore their friendship.
Maybe in that fanfic, there are misunderstandings between Harry and the Weasleys. For example, they might have had an argument over something like magic use or family values that led Harry to dislike them.
Maybe in the fanfic, there could be a misunderstanding between them. For example, Ron might have accidentally broken Harry's trust in some way, like revealing a secret of Harry's that he wasn't supposed to.
Another reason might be related to their different goals. Ash is mainly focused on becoming a Pokémon Master, while Misty might have her own goals that sometimes conflict with Ash's journey. This could lead to friction between them and eventually make Ash develop negative feelings towards her.
One reason could be that some fans want to explore different character dynamics. The original Bella - Edward relationship is so well - known and often idealized, so making Bella hate Edward creates a whole new set of tensions and story possibilities.
One possible reason could be a miscommunication. Maybe Hermione accidentally reveals a secret of Harry's that he didn't want known, and this causes him to feel betrayed and start to hate her. Another reason could be jealousy. If Hermione gets more attention or praise for her magical abilities than Harry in the fanfic, he might develop feelings of envy and hatred. Or perhaps there's a love triangle situation where Hermione is involved with someone Harry doesn't like, and that causes his hatred.
Perhaps in the fanfic, Brick has some sort of relationship with Blossom that she doesn't approve of. It could be a forced romantic relationship or a partnership where Brick is constantly overshadowing Blossom or not respecting her. Another aspect could be that the fanfic changes the fundamental nature of the world they exist in in a way that Blossom finds unacceptable, and Brick is somehow a symbol of that change.
One possible reason could be some past misdeeds by the parents. Maybe they were neglectful or made decisions that seriously affected Ciel's life in a negative way in the context of the fanfic.
