The theme of found family is also quite prevalent. Harry, being adopted, forms new relationships that become like family to him. These new families may have different dynamics compared to what he had in the wizarding world, and the stories often explore how these new relationships develop and support him in his new life in the crossover universe.
Another theme is the clash of cultures. For example, if Harry is adopted into a non - magical world like a superhero universe, there will be a contrast between the magical and non - magical ways of life. It's about how Harry and the other characters adapt to this difference. For instance, in a crossover with the Marvel Universe, Harry has to learn about modern technology and superhero ethics while still having his own magical abilities and values from the wizarding world.
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.
One common theme is identity. Since Harry is adopted, he may struggle with who he really is in relation to his new family and his wizarding heritage. Another theme could be family dynamics, as he has to adapt to a new family structure. And there's often the theme of secrecy, as his adoption might be something that needs to be hidden for some reason in the wizarding world.
One common theme is redemption. Harry often has to overcome his past abuse and find a new path in life with his adopted family. It's about rising above the pain and becoming a better person.
Power is a major theme. How the powerful characters from both universes interact and deal with power is often explored. For example, characters like Voldemort and Rhysand might be pitted against each other in some fanfictions. Friendship is also a theme, as characters from both sides form new alliances. In many stories, a Hogwarts student might become friends with a fae from Acomaf, and they learn from each other's strengths and weaknesses.
One common theme is the clash of cultures. The magical cultures in Harry Potter and Transvanya are quite different. For example, the way magic is taught in Hogwarts compared to how it's practiced in Transvanya. Another theme is the idea of cooperation. Often, the characters from both worlds have to work together to solve a big problem, like a powerful dark magic that threatens both universes.
One common theme is the exploration of unexpected relationships. The MPreg aspect often leads to new and unanticipated connections between characters.
One common theme is the clash of different cultures. For example, when Harry Potter crosses with Star Trek, the scientific and technological culture of Star Trek clashes with the magical culture of Harry Potter. Another theme is the exploration of new powers. When combined with something like the X - Men, new powers and abilities can be explored. Also, friendship often remains a key theme. No matter what world Harry enters in the crossover, his ability to form strong friendships and alliances is always important.
One common theme is the clash of cultures. Itachi comes from a world of ninjas with its own set of values and traditions, while the Harry Potter universe has its own magical culture. Writers often explore how Itachi adapts to this new world and how the magical characters react to his presence.
One common theme is the clash of different power systems. In Harry Potter, there's magic, and in DC, there are super - powers. Fanfictions often explore how these two types of powers interact, whether they complement each other or cause conflict.
One common theme is the clash of two different power systems. Magic from Harry Potter and the symbiotic powers of Venom. Another is the exploration of how different characters from both universes would interact.
