One reason could be the pressure. Harry is constantly under the spotlight during the tournament, and he may not like that kind of public scrutiny. In fanfiction, this pressure could be amplified to an unbearable level for him.
In fanfiction, the Triwizard Tournament could be used as a political tool by some characters. Harry, who is often averse to politics and power games, would dislike being part of such a manipulated event. The tournament may be full of behind - the - scenes plotting and scheming that he wants no part of.
Perhaps the tasks in the Triwizard Tournament are made more difficult or dangerous in fanfiction than in the original story. Harry, who has already faced so many challenges, might find this additional burden too much to handle and thus grow to hate the tournament.
One reason could be a conflict of interests. If they are competing for the same thing, like a magical artifact or a position in a magical society, and Susan uses underhanded tactics, Harry would hate her.
One possible reason could be his lingering resentment towards James Potter, Harry's father. Snape and James had a long - standing feud during their school days. Since Harry looks a lot like James, Snape might be transferring his old grudges onto Harry.
One reason could be that he doesn't like how some fanfiction writers misinterpret his character. They might make him act in ways that are completely out of character in relation to Renesmee. He has a certain image of himself and his relationship with her, and fanfiction can mess that up.
One reason could be that he was treated unfairly by other shinobi. If he was constantly looked down upon or discriminated against by his fellow shinobi, it might make him develop a hatred for them.
It's possible that the writer of the fanfiction has given Akeno a backstory or personality trait that directly clashes with Naruto's. Maybe she is extremely arrogant and Naruto, who is humble and believes in everyone's potential, would find that detestable.
It might be due to the way their goals are presented in fanfiction. Naruto is often about protecting his village and friends. If Artemis's goals in the fanfic are in conflict with Naruto's, like if she's more focused on her own self - interest in the story, Naruto would hate her.
One possible reason is that Naruto is so focused on his ninja training and his goals in the shinobi world that he views Christmas as a distraction. He might think it takes people's attention away from more important things like self - improvement and protecting the village.
One reason could be competition. If Chloe is presented as a rival in the fanfiction, Ash might hate her for trying to outdo him in Pokemon battles or other aspects. For instance, if she constantly shows off her skills or Pokemon, it can make Ash feel annoyed.
In the Harry Potter series, Harry participated in the Triwizard Tournament. The Triwizard Tournament was a friendly competition between the three largest Wizarding schools in Europe (Hogwarts, Beothbatons, and Durmstrang). It was held every five years and the three schools took turns hosting it. The competition restarted in 1995. Although Harry did not sign up, he was chosen by the Goblet of Fire and had to participate in the competition. He had gone through three magical tests in the game: the first was to get the golden egg from the attack of the dragon, and Harry rode the Firebolt to circle around the hungarian tree peak dragon and finally successfully cleared it. The second was to save the hostage underwater. Harry swallowed the gillyweed, and gills grew on both sides of his face to allow him to breathe freely in the water for a long time. He successfully rescued the hostage. The third was the maze adventure. In the cemetery, Harry witnessed Voldemort's resurrection and escaped back to Hogwarts with the help of his parents 'images. Cedric's death had once again reminded people of the dangers of the Triwizard Tournament, which had not been held since 1995. Harry Potter and the Goblet of Fire was not enough.

It could be that there are unforeseen circumstances in the Triwizard tasks. For example, the magical creatures or the challenges are far more dangerous than expected. The Triwizard maze might be filled with deadly traps that are not properly controlled, and Harry could be caught in one of them, leading to his death.
