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.
One popular 'Harry Potter is adopted crossover fanfiction' is 'Harry Potter in the DC Universe'. It's really interesting as it combines the magical world of Harry Potter with the superhero - filled DC 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.
They're popular because they offer a fresh take on the well - known Harry Potter story. By changing his family situation through adoption, it can completely shift the dynamics of the story.
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.
In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.
One popular 'Harry adopted crossover fanfiction' is 'Harry Potter and the Avengers'. In this, Harry is adopted by one of the Avengers, usually Tony Stark. It combines the magic world of Harry Potter with the superhero world of the Avengers in an exciting way. There are also ones where Harry is adopted by characters from other fandoms like Doctor Who, which often leads to interesting plot twists and new adventures for Harry.
Sure, it's quite possible. Fanfiction writers love to blend different fictional worlds. In a 'The Mummy (2017)' and 'Harry Potter' crossover, we could see the mummy's powers being pitted against the spells of Hogwarts students. Maybe the mummy is brought back to life in the wizarding world and causes chaos. There are endless possibilities for interesting storylines in such a crossover fanfiction.
One idea could be that Tinkerbell finds her way into the wizarding world of Harry Potter. Maybe she gets accidentally transported there by some magical mishap. She could use her fairy magic in Hogwarts, like helping to repair broken objects in a more sparkly and unique way compared to the Reparo charm.
A popular one is 'Fem Harry and the World of Middle - earth'. This fanfic is really interesting because it crosses over the Harry Potter universe with Tolkien's Middle - earth. Here, Fem Harry has to adapt to the very different cultures and magic systems in Middle - earth, and there are some great character interactions that add depth to the story.
