Maybe as a form of character exploration. By putting Harry in such an odd situation, the writer can explore how he would react, how his friends would respond, and what kind of character growth or change could come from this strange experience.
It could be for comical purposes. The idea of the powerful and heroic Harry Potter having to deal with something as mundane and embarrassing as wearing diapers can be quite humorous. It adds a touch of absurdity to the usually serious Harry Potter universe.
Some writers might do it to make a statement about how Harry Potter, who is used to the grandeur of Hogwarts and the wizarding world, can adapt to a very different and confined space like a fridge. It could be a study of his character's adaptability. Also, it could be a form of satire, poking fun at the sometimes overly - serious nature of the original Harry Potter stories.
There are several reasons. One is to create humor. The contrast between the serious and magical world of Harry Potter and the rather silly concept of diapers can make for some very funny stories. Another reason could be to explore themes of regression or new beginnings. Diapers can symbolize a fresh start or a return to a more innocent state. And for some fans, it's just a way to stand out in the large and diverse fanfic community by coming up with a really unusual concept that still ties back to the much - loved Harry Potter franchise.
He could wear a mask to protect his loved ones. If there's a new threat in the wizarding world that targets him and those close to him, a mask would be a way to keep his identity hidden so that his enemies can't use his friends and family against him.
Perhaps there's a potion accident. Harry might have been experimenting with a new potion in Potions class, and something went wrong. The potion could have affected his body functions, resulting in his need to wear diapers. It could add an interesting and comical twist to the story.
Some writers might do it for the shock value. It's a very unusual concept that can grab readers' attention.
Well, some people might write it for shock value. They want to create something really out of the ordinary that will make readers go 'wow' or 'eww'.
Another aspect is quality control. A lot of fanfic varies greatly in terms of writing quality. Some people might have had bad experiences with poorly written Harry Potter fanfic in the past and thus choose to say no to all of it. They don't want to waste their time sifting through sub - par stories when they can just re - read the original, well - crafted novels.
Maybe they just don't understand the real essence of Harry Potter. They might have only seen a small part of it or misinterpreted some of the more emotional or character - developing moments as signs of weakness, which is completely wrong.
One reason could be the unfinished business in the original story. For instance, some fans might be curious about what happened to certain minor characters after the main series ended. Fanfic provides a space to explore that. Also, the sense of community around Harry Potter fanfic can be very appealing. People can discuss and share their thoughts on different fanfic stories, which makes them want to linger. Additionally, the creativity of fanfic writers in expanding the magical world and creating new storylines can be captivating.
There is no valid reason. Harry Potter has been around for a long time with a very distinct identity. If someone thinks this, it might be because they are making a very random and baseless association. It could be that they have some misunderstanding about the nature of fanfics in general and how they are related to original works like Harry Potter.
