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.
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 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.
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 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.
Maybe he's curious about different interpretations of his own story. In fanfictions, his character might be in new and exciting adventures that the original books didn't cover.
It could be a case of misinformation. Someone in the story might have spread false rumors about Harry being the father for their own motives. Perhaps they wanted to cause chaos or gain something from the situation. So, the whole idea of Harry being the father is just a false story that gets spread around the wizarding community.
One possible reason could be the betrayal he faced from some people in the wizarding world. For example, some students at Hogwarts might have spread false rumors about him or treated him unfairly because of his fame as 'The Boy Who Lived'. This could have led him to develop a general dislike for humans.
One possible reason could be for self - protection. By pretending to be poor, he might avoid unwanted attention. Maybe he doesn't want people to target him because of his wealth, just like in the original story where he was often in danger due to his fame. Another reason could be to better understand his friends who are actually poor. He wants to experience life like them and build stronger bonds with them.
