One common theme could be the clash of different magical systems. For example, if it's a crossover with a different fantasy world, how the magic from Harry Potter compares and interacts with the other world's magic. Another theme might be the exploration of different cultures. If it crosses over with a story from a different cultural background, it can show how the characters from Harry Potter adapt to new cultural norms.
Often, there's the theme of friendship and teamwork. When characters from different universes come together in a crossover, they have to learn to work together. In a non - inappropriate 'Harry Potter crossover' (ignoring the 'lemon' part which is not suitable), they might face a common enemy or a big challenge that requires all of their skills combined. For instance, if it crosses with a superhero universe, the wizards and the superheroes need to figure out how to use their powers in harmony to save the day.
One common theme could be friendship. When characters from Harry Potter cross over into another universe, they often form new friendships. For example, if they cross over into a superhero universe, they might team up with the heroes there and learn about different kinds of heroism. Another theme is the exploration of different magic systems. If it's a crossover with a different fantasy world, comparing and contrasting the magic in Harry Potter with that of the other world can be really fascinating.
One common theme could be the family dynamic. Since Vegeta is Bra's father, exploring their relationship in terms of his protectiveness over her or her admiration for him in a non - inappropriate way.
Another theme could be family loyalty. Despite all their differences and conflicts, they are still family. So some fics may focus on how they struggle with their loyalty to each other and to their family name. They might have to make difficult choices that test this loyalty, like when Zuko was on his journey of self - discovery and still had to think about his connection to Azula.
Well, aside from inappropriate aspects, one common theme could be their journey of self - discovery while being in each other's orbit. Sasuke and Naruto are both on a path to find themselves, and in many fanfics, they influence each other's growth. Also, the theme of loyalty might be present, as they have a complex relationship where loyalty is constantly tested and redefined.
One common theme could be Rangiku's relationships. For example, her relationship with Toshiro Hitsugaya might be explored in a more platonic or friendly way. Another theme could be her growth as a character, like how she overcomes challenges in the Soul Society.
One common theme could be friendship. Despite the odd pairing, they could form an unusual friendship. Maybe Myrtle helps Harry in some way that others can't, like providing insights into Hogwarts' secrets. Another theme might be growth. Harry could help Myrtle move past her sad state and grow as a character.
Well, in Naruto crossovers (excluding the 'lemon' part), a common theme is power - up. When Naruto crosses with another universe, he might gain new abilities or face challenges that force him to level up in a different way. For example, if he crosses with a world of magic, he may have to learn to control new types of energy.
Some popular themes include the relationship between the different houses at Hogwarts. How Gryffindors interact with Slytherins in a more positive way than what is shown in the original books. There are also fanfics about magical inventions. Maybe a new type of broomstick or a magical device that can help in dueling. And then, the theme of magical families and their traditions. For instance, the Weasley family has a lot of unique traditions, and fanfics can explore those in more detail.
Well, often there's the theme of mentorship in a different light. Instead of the traditional teacher - student relationship, it could be a more equal exchange of knowledge and support. Another theme could be the discovery of hidden qualities in each other. Snape might see Harry's more mature and complex side, and Harry could see Snape's more vulnerable side, which is different from how they interact in the original books.
A theme might be the exploration of their individual personalities within the context of their relationship. Gray's cool and sometimes brooding nature, and Erza's strong - willed and determined personality could lead to interesting interactions. They might also have themes related to protecting each other, as they are both characters in a world full of danger.
