The common themes include expanding on the family backgrounds of the characters. We might see more about the Weasley family tree or the Black family's history. Love and romance are also prevalent, whether it's between main characters or secondary ones. Additionally, fanfic often delves into the world of dark magic and how the characters might be tempted by or fight against it.
One common theme is exploring the backstories of minor characters. For example, we might see fanfictions delving into the life of Neville Longbottom before he came to Hogwarts. Another theme is alternate universes, like a world where Voldemort won the first war. And of course, there are often romances that were not fully explored in the original books, such as the relationship between Luna Lovegood and someone else.
Power dynamics is also a common theme. Since purebloods are often seen as having more power in the wizarding world in the original series, fanfics might explore how Harry fits into this power structure. Maybe he challenges it or maybe he becomes part of it in a different way.
The exploration of power is also a major theme. Both Harry Potter and Loki have different forms of power. Harry has his magic skills and the power of love and friendship. Loki has his Asgardian powers and his wits. Fanfics often play with how these powers are used, compared, and sometimes combined in the face of various challenges within the story.
Power corruption is a common theme. Since Harry has so much power in the original story, in the fanfic, it often gets twisted and he might be lured by the dark side through the allure of more power. Another theme is the blurring of good and evil. The lines between what's right and wrong in magic become less clear.
Love and relationships can also be a common theme. A succubus may form unexpected relationships with the characters in the Harry Potter world. It could be a romantic relationship, a friendship or a mentorship. These relationships often challenge the traditional ideas of love and connection in the wizarding world. For instance, a succubus might fall in love with a wizard, and they have to overcome the differences in their natures and the potential prejudice from others.
A third theme could be the mystery aspect. Vampires are often associated with mystery in folklore. In 'Harry Potter Vampire' fanfics, this mystery can be incorporated into the story. For instance, a vampire character might hold the key to an ancient mystery in the wizarding world, and Harry and his friends have to figure out how to unlock it by getting to know the vampire better.
One common theme is discovery. Writers often explore the discovery of new beasts, like a hidden species in the Forbidden Forest. Another theme is protection. Fans like to write about protecting these magical creatures from harm, whether it's from dark wizards or from being hunted.
One common theme is the struggle with academic work. Since Hogwarts has a lot of reading and writing, a dyslexic character would find it hard, like in many fanfics where they have to work extra hard to keep up with their classmates in subjects like Potions which require reading long ingredient lists.
Another theme is the clash of cultures. The world of Harry Potter and the world of Dovahkiin are very different in terms of their cultures, values, and social structures. Fanfic writers like to explore how characters from these two worlds adapt to each other's cultures. It can lead to some really interesting character development and plot twists.
Another theme is friendship. They often show Nott forming unexpected friendships, perhaps with characters from different houses. This is a contrast to the often - divided houses in the original story. For example, he might become friends with a Gryffindor, which is quite an interesting concept to explore.
