Another theme is power. Harry's anger might lead him to explore or gain more power to fight against his oppressors. He could discover new spells or magical abilities out of his rage and determination to not be pushed around. In some fanfics, this exploration of power while being angry can lead to some really interesting plot twists.
One common theme is justice. Since Harry is angry, it often involves him seeking justice for wrongs done to him or his friends. For example, if a character was wrongly accused in Hogwarts, Harry's anger would drive him to clear their name.
One common theme is betrayal. Harry often feels betrayed by those he trusts, like the Ministry of Magic or certain teachers, and his anger stems from that. For example, in some fanfics, he discovers that they have been using him for their own purposes.
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.
