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 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.
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.
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.

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.
There's also 'Link Potter and the Chamber of Secrets' which is a crossover with 'The Legend of Zelda'. It's really cool as it blends the two very different universes. The author manages to incorporate elements of Zelda like the Triforce and Link's abilities into the world of Hogwarts. It's full of exciting adventures and interesting interactions between the characters from both franchises.
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.
