Perhaps a theme could be about the unfairness in the Hogwarts houses. In this kind of fanfiction, the writer might expand on how the house sorting is a bad idea and causes more problems than solutions. Also, it could focus on the dark side of the wizarding world that the original series didn't explore enough, but in a negative way towards the overall 'Harry Potter' concept.
Some people might create such fanfiction because they have a different view of the original 'Harry Potter' series. Maybe they don't like the characters, the plot, or the overall world - building. They want to express their dissatisfaction through creating their own stories that go against the general positive perception of 'Harry Potter'.
A theme could be redemption. Perhaps Snape has done something so unforgivable in the eyes of Harry that it makes Harry think Snape sucks. And the story could be about Snape trying to redeem himself in Harry's eyes. Or it could be about jealousy. Snape may be jealous of Harry's fame and Harry may sense this and thus dislike Snape.
Another theme is the friendship and teamwork between the Harry Potter characters and the Totally Spies characters. They usually come together to face a common enemy, and the stories focus on how they learn to work with each other's different skills and abilities. This can involve things like the witches and wizards teaching the spies about magic, and the spies teaching the magical folk about modern technology and spy tactics.
One reason could be that the creators of such fanfiction are die - hard Snape fans. They might feel that Snape is the most interesting and underappreciated character in the 'Harry Potter' series. So, they create fanfiction where Harry Potter, who they may see as getting too much attention in the original, is not as great, to put more focus on Snape.
The 'daddy sucks' in Harry Potter fanfiction might refer to a negative view of father - like figures. For example, some might explore a negative portrayal of Vernon Dursley. However, this kind of theme can be quite controversial as it goes against the general family - oriented values in the original series.
One possible reason is to show a contrast. Since Bill is often seen as a reliable and good - natured character in the original series, making him 'suck' in fanfiction can create a shock value and make the story more interesting. It can also be a way to explore the flaws of a seemingly perfect character.
The world of Harry Potter is rich with magic, unique characters, and a complex wizarding society. Fanfiction writers are captivated by it as they can explore different aspects. For example, they can create new relationships between characters, or imagine different scenarios within Hogwarts. The magic system provides a great framework for creativity, allowing for countless magical adventures in fan-created stories.
One possible theme is the search for inner peace. In the Harry Potter world, characters often face great turmoil, and by introducing Buddhist concepts, they could seek inner peace through meditation or self - realization, like Harry might find a new way to deal with his PTSD from all his encounters with Voldemort.
Themes could include the blurred lines between good and evil. If Harry is a fan of Voldemort, it challenges the traditional view of their roles. Another theme might be the exploration of dark magic. Since Voldemort is associated with it, Harry's fascination could lead to a deeper look into the nature of dark magic.
Friendship is a big theme. Just like in the original Harry Potter series, in these fanfictions, the guitarist could form strong bonds with other characters while sharing their music. For example, they might write a song together to cheer up a friend who is going through a tough time.
