Yes, there are some. Some fanfictions explore the darker side of Harry's life with his uncle in great detail. They often delve into the emotional and psychological abuse he might have endured. However, the quality can vary greatly from one to another.
Common themes include the power of friendship as a counter to the abuse. Even in the midst of being mistreated by his uncle, Harry might find friends who support him in the fanfiction. Also, the theme of self - discovery is often present. Through the experience of abuse, Harry may learn more about himself and his own strength. Additionally, the exploration of family dynamics outside of the magical world is a big part of it, as it contrasts with the wizarding family he discovers later.
Often, there is a theme of Harry's isolation. Since in this fanfiction concept his parents are the abusers, he may feel even more alone than in the original story. Also, there might be a theme of self - discovery where Harry has to re - evaluate everything he thought he knew about his family and himself. This can lead to a more complex and nuanced character development compared to the original series.
One possibility could be that Harry, out of a sense of duty or some form of magical coercion, decides to follow his uncle's every order in order to protect his aunt and Dudley from a new magical threat. He might suppress his own desires and instincts to keep them safe.
There could be fanfictions where Harry is sent to a different magical school where he encounters abusive teachers or fellow students. Or maybe it's a story that explores the psychological impact of abuse on Harry's magic and his relationships with others.
Perhaps his uncle has a very intimidating appearance or a loud voice that scares Harry. In the fanfiction, it could be that his uncle has a certain look in his eyes when he's angry that makes Harry tremble with fear.
In my opinion, it is not ethical. Harry Potter is a beloved story with a wide range of fans, including those with disabilities. Creating fanfiction that involves abusing disabled characters is cruel. It can be offensive to disabled people who see themselves in those characters. Fanfiction should be a platform for creativity that respects the original work and the diverse audience it has.
On the other hand, it could be positive in a way. Maybe through submitting, Harry learns more about his uncle's insecurities and past, which could lead to a new understanding and a form of reconciliation between them.
Well, if we meet Uncle John in a Harry Potter fanfiction, he could also be a character from a different magical culture. He might introduce new spells, creatures or ways of magic to Harry. His presence could expand the already rich world of Harry Potter and create new adventures for Harry and his companions.
Well, there are likely some out there. Fanfiction allows for a wide range of interpretations. This particular concept is quite dark and against the normal perception of Harry's family. When looking for it, you should be prepared for some disturbing content. Some fanfictions might handle this topic in a more psychological way, delving into how Harry would cope with such a false reality of being abused by his parents.
