One common theme is the clash of different worlds. Sonya Blade comes from a very different universe than Harry Potter, so there's often exploration of how their different cultures and ways of life interact. For example, her combat - based skills compared to the magic in the wizarding world.
One popular 'Harry Potter Sonya Blade' fanfic could be 'The Unlikely Alliance'. It weaves an interesting story where Sonya Blade somehow gets transported to the Harry Potter universe and teams up with the main characters. There are elements of magic and combat combined in a unique way.
One common theme is adventure. They might go on missions together, facing various challenges and enemies. Another theme could be friendship. The story could explore how they become friends, trust each other, and support one another. Also, there could be a theme of mutual respect, where they respect each other's skills and abilities in combat or other areas.
Friendship or a slow - burn relationship is also a theme. Given their initial differences, their journey to becoming friends or more is a popular plot. They start off as adversaries but gradually come to understand and respect each other. In some fanfics, this relationship development is the central focus, with their conversations and shared experiences highlighting the growing bond.
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.
