Perhaps the fanfic will show that the house system is a big problem. Instead of promoting unity, it creates intense rivalries that lead to constant fighting. There could also be a problem with the food. Maybe it's always spoiled or there's not enough. And the social environment could be toxic, with students gossiping and spreading rumors all the time, which makes Hogwarts seem like a horrible place.
In this kind of fanfic, there might be a lack of safety. For example, the magical creatures in the Forbidden Forest could be running wild around the school, endangering the students. The curriculum could also be a factor. It might be too difficult or taught in a very ineffective way. And there could be issues with the school's hierarchy, like the prefects misusing their power.
Well, in some fanfics, the idea that Hogwarts is a horrible school might come from a different perspective. Maybe the author wants to explore the dark side of the school that wasn't fully shown in the original books. For example, the strict rules could be seen as overly oppressive to some characters in the fanfic.
It could also be that the fanfic might interfere with the way he wants his story to be remembered. His adventures at Hogwarts were real and important to him, and when fanfic changes the narrative, it's like his story is being disrespected. For example, if a fanfic portrays him as cowardly when he was actually brave, that would surely make him dislike it.
One possible reason could be that he feels constantly in danger at Hogwarts. With all the dark magic threats and attacks that keep happening, he might think leaving would keep his friends and himself safer. For example, after the Chamber of Secrets incident, he might have considered leaving to protect others from Voldemort's influence.
One possible reason could be misinformation spread by the Ministry of Magic. They might have spread false rumors about Harry being a threat, which influenced the Hogwarts community. For example, if the Daily Prophet printed false stories about Harry's supposed dark magic activities, it could turn some students and staff against him.
In the 'harry potter after hogwarts fanfic', a really interesting plot could be about the discovery of new magical creatures or lost spells. Harry, being the adventurous type, might go on quests to explore these new elements. He could also get involved in international wizarding relations, using his fame and experience to bridge gaps between different wizarding communities around the world. This would open up a whole new world of magic for the readers to explore.
One possible reason could be that he was under the influence of a powerful dark magic or a curse that made him lose control. Another reason might be that he was tricked into believing Hogwarts was a threat to the wizarding world in some extreme way. Maybe a powerful enemy manipulated him to think that destroying Hogwarts was the only way to save everyone.
A possible plotline could be Harry being sent to a different school as part of an exchange program. At the new school, he has to prove himself all over again. He meets new friends and enemies. For instance, if it's Beauxbatons, he might be challenged by the students who think he's just a famous name from Hogwarts and not really that talented.
Yes, it is possible. Fanfiction allows for creative reinterpretations of established universes. In this case, imagining Harry Potter as the founder of Hogwarts could lead to some really interesting storylines. It could explore how his modern - day knowledge and experiences would shape the school in its earliest days, perhaps introducing new spells or ways of teaching that are different from what we know of the original founders.
Bullying is a common element. Whether it's physical like hitting or verbal like name - calling, it can make school a horrible place for the victim.
In the 'Harry Potter Controls the Elements Fanfic', perhaps Harry discovers his element - controlling powers gradually. He first starts with something simple like controlling the wind to cool himself on a hot day at Hogwarts. Then, as he grows more powerful, he can combine elements. He could create a storm by mixing air and water elements, which he uses to protect his friends from a group of Death Eaters.
