Well, in some fanfiction, Harry might be afraid of adults because he has seen the dark side of the wizarding world which is often controlled by adults. He has witnessed Voldemort's rise and the inaction or wrong actions of some adult wizards. This could lead to a sense of mistrust and fear towards all adults in the fanfiction. Also, if he has been betrayed by an adult he trusted in the fanfiction, that would surely make him afraid.
In fanfiction, Harry Potter could be afraid of adults due to the pressure they put on him. He is the 'Chosen One' and adults constantly have expectations of him. They might push him into dangerous situations or force him to grow up too fast. This overbearing presence of adults in his life, always dictating what he should do, could easily make him afraid of them. For example, if in the fanfiction Dumbledore is overly secretive and manipulative, it would add to Harry's fear of adults.
One possible reason could be his past experiences with some cruel adults, like the Dursleys. They treated him horribly, so in fanfiction, this trauma might make him generally fearful of adults. Another reason could be his experiences with certain authority figures at Hogwarts who may have been strict or unfair, which could be exaggerated in fanfiction to create a fear of adults.
One possible reason could be his past traumas. Harry has faced many dangerous and life - threatening situations. For example, the numerous attacks from Voldemort and his Death Eaters. These experiences might have made him overly cautious and averse to physical touch as it could potentially be from an enemy. Also, his upbringing in the Dursley's household wasn't exactly warm and fuzzy. The lack of positive physical contact there could have contributed to this fear.
In fanfiction, Harry could faint due to some sort of magical disease or curse. There could be a new, made - up illness that affects wizards and one of its symptoms is fainting. Or perhaps he's in a situation where he's cut off from his magic for a while and his body, which is so used to having magic, goes into shock and he faints. It could also be that he's in a place with really strange or strong magical energy that his body can't handle, and this causes him to pass out.
It could be due to some kind of self - sacrifice he made in a previous battle. For example, he might have used a very dangerous spell that had a side - effect of slowly killing him to save his friends or the wizarding world.
One reason could be to explore the darker side of human nature. Even though Harry is a hero in the original series, fanfiction writers might want to see how he would be affected if he was pushed to his limits. Another reason is to create a more complex and controversial storyline. It grabs readers' attention as it goes against the normal perception of Harry.
Some fanfiction writers may have a different vision for Harry Potter's character. They might see him as more of a diplomat or a healer within the wizarding world, rather than a fighter. So, they write stories that reflect this different view of the character, where he uses his wits and other skills rather than engaging in physical or magical combat.
One reason could be that the official Harry Potter canon is so extensive and detailed that it overshadows fanfiction. The original story has such a rich world, characters, and plotlines that it becomes the main focus for many fans, leaving less room for fan - created stories.
One reason could be safety. Some fanfiction authors might think that Hogwarts is too dangerous for Harry, so they make him homeschooled to keep him out of harm's way.
One reason could be a reaction to the Ministry of Magic's mismanagement. In the original story, the Ministry often made mistakes and had corrupt elements. In fanfiction, this could lead to Harry becoming an anarchist as a way to oppose such a flawed system.
One possible reason could be jealousy. Maybe Ginny feels overshadowed by Harry's fame even within their relationship and she strays to someone who makes her feel more special on a personal level. Another reason could be miscommunication. If they have been too busy with their respective wizarding duties and haven't been communicating well, Ginny might feel neglected and be drawn to someone else who seems to give her more attention.
One reason could be the extreme hardships the characters face in the original story. For example, Harry has lost his parents, faced Voldemort numerous times, and seen many friends die. In fanfiction, this could be amplified to a point where a character feels they have no will to live. Another aspect could be related to the sense of isolation. Some characters, like Snape, were always sort of alone in their struggles, and in fanfiction, this could lead to a loss of the will to live.
