One idea could be that Harry Potter and his friends are transported to the DC Comics universe. They could team up with the Justice League to fight a common enemy like Voldemort who has somehow gained powers from a DC Comics villain. For example, Voldemort could have made a deal with Darkseid to gain more power in exchange for helping him conquer the wizarding world first. Then, Harry and the likes of Superman, Batman, and Wonder Woman would have to combine their magical and super powers to stop them.
There's a story on AO3 where Batman visits Hogwarts to investigate some strange disappearances. What makes it stand out is how well the author captures Batman's detective skills in the magical setting. He's able to use his gadgets and his wits to figure out that a Slytherin student is using a dark magic spell that's related to a DC Comics - style super - power experiment gone wrong. It's a complex and engaging plot.
One great place to find Harry Potter and DC Comics crossover fanfiction is on Archive of Our Own (AO3). There are many creative stories there. Some might have Harry Potter characters using magic in the DC universe, like Harry using spells against villains in Gotham. Others could involve DC heroes and villains in Hogwarts, perhaps Batman trying to solve a mystery within the castle walls.
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.
Definitely Harry Potter and Batman. Batman is known for his detective skills and strategic thinking, while Harry has his own brand of resourcefulness and knowledge of magic. They could work together to solve a mystery that involves both the wizarding world and Gotham City. Maybe there's a dark wizard causing trouble in Gotham, and Batman needs Harry's help to understand the magical aspects of the case.
One popular 'Harry Potter' and 'DC Comics' fanfiction might be those that cross over the magical world of Hogwarts with the superhero - filled universe of DC. For example, stories where Harry Potter characters somehow end up in Gotham City. There are also ones where Superman or Batman might visit Hogwarts. These crossovers are interesting as they blend two very different yet equally captivating fictional worlds.
Overall, crossovers between Marvel and DC Comics aren't that common. Both companies have their own distinct universes and storylines, and when they do crossover, it's a big deal and attracts a lot of attention from fans. But it doesn't happen frequently.
It could be really exciting. Maybe Harry Potter characters could visit Gotham City. Harry could use his magic to help Batman fight crime in a way that normal gadgets can't. For example, he could use spells to disarm villains from a distance or create magical barriers to protect civilians.
There's 'Magic and Metahumans'. This fanfiction has a great plot where the Death Eaters from Harry Potter somehow end up in Metropolis. Superman has to deal with their dark magic while Harry and his friends try to find a way back to their world. It's full of action and interesting character dynamics.
One great one is 'The Wizard and the Caped Crusader'. It combines the magic of Harry Potter's world with the superhero action of DC. It has a really interesting plot where Harry somehow ends up in Gotham City and has to team up with Batman to fight a new kind of dark magic that's threatening both worlds. Another is 'Magic in Metropolis' which shows Superman dealing with the sudden appearance of Hogwarts students in his city. They bring chaos at first but then they all work together to face a common enemy. There's also 'Potter and the Justice League' which features Harry joining forces with the entire Justice League to take on Voldemort who has made an alliance with some of DC's villains.
