A recurring theme is the discovery of new worlds. When Harry enters a superhero - dominated world or vice versa, there's a sense of wonder and discovery. They have to learn about the rules, the people, and the threats in this new environment. It's like Harry learning about the superpowers and the superhero society, and the superheroes learning about magic and the wizarding society. This theme adds an element of adventure and exploration to the fanfiction.
One common theme is the clash of different cultures. For instance, when Harry Potter's magical world collides with a superhero world, there's a contrast between the use of magic and superpowers. Another theme is the idea of heroism. Harry is already a hero in his own world, and when paired with superheroes, they often have to work together to face greater threats.
Power and its implications are also common. Harry's power, whether it's his magic from the Potter universe or new powers gained from crossovers, plays a role in attracting characters to his harem. Also, the theme of self - discovery is there. Harry learns more about himself as he interacts with different characters in the harem.
Another theme is the idea of a shared threat. Since both Percy and Harry are heroes in their own right, a lot of crossover fics will have them face a danger that neither could handle alone. This could be a new dark force that combines the worst of the magical and demigod worlds, like a villain who can use both dark magic and the power of the Titans. It makes for some exciting plotlines as they have to learn to work together.
The theme of redemption can also be common. If Harry is adopted into a world where there are characters with a dark past, like some of the anti - heroes in certain fandoms, his presence can sometimes be a catalyst for their redemption. And of course, the exploration of different magic systems or powers is a major theme. If he's adopted into a world like the Inheritance Cycle, he has to understand how his magic compares to the dragon - riding magic there.
Friendship and alliances are often themes. When Harry is in a crossover situation, he has to form new friendships and alliances. His Animagus form can sometimes be an advantage in making these connections, as it can make him seem more relatable or trustworthy to certain characters from other universes.
One common theme is identity exploration. Since it's a crossover, characters from different universes have to re - evaluate who they are in this new combined setting. In the context of slash, it often means exploring new relationship dynamics that are different from the original source materials.
A major theme is the exploration of new relationships. In these fanfictions, Harry's pregnancy often leads to new connections with characters from the crossover world. These relationships can be friendly, romantic, or a complex mix of both. It also explores how his existing relationships from the Harry Potter world are affected. For instance, how Ron and Hermione might react to his new situation in the crossover context. The fanfictions often show how these relationships evolve over time as Harry progresses through his pregnancy.
One common theme is the clash of cultures. The ninja - like Akatsuki with their own values and traditions coming into the very different wizarding world of Harry Potter. Another theme is power struggles. Akatsuki members are often power - hungry in their own universe, and in the Potter world, there are different power dynamics with the Dark Lord and the Ministry of Magic.
A common theme is also adaptation. Fem Harry has to adapt to the different social and cultural norms of the Twilight world. For instance, the way the Cullens live as vampires is very different from what she's used to in Hogwarts. There are also themes related to secrecy and discovery. Her magic is a secret in the Twilight world at first and then gradually gets discovered, which causes all sorts of reactions from the Twilight characters.
One common theme is the clash of different worlds. For example, when Harry Potter is rescued in a crossover with another universe, like the Star Wars universe, there's a lot of focus on how the magic of Harry's world interacts with the technology and different species in Star Wars. It's about two very different concepts trying to coexist.
One common theme is cultural exchange. Since Hetalia is about different nations, when combined with Harry Potter, it often shows how the different cultures of the Hetalia characters interact with the magical culture of the Potterverse. For example, how they react to magic spells compared to their own 'powers' in Hetalia.
