What are some interesting crossovers in Harry Potter Dresden Files fanfiction?

One interesting 'Harry Potter Dresden Files' fan fiction could be one that combines the magic systems of both. For example, a story where Harry Potter and his friends encounter a problem that can only be solved by using Dresden's more gritty and street - wise approach to magic. Maybe they have to deal with a dark wizard who is using a blend of muggle - influenced dark magic that is more in line with the Dresden Files universe.

One idea could be that Harry Potter accidentally travels to the world of the Dresden Files. He could meet Harry Dresden and they team up to fight a dark magic threat that is affecting both their worlds. Maybe a powerful dark wizard from the Potterverse has found a way to use the magic from the Dresden Files world to enhance their power.

He could bring some of his unique spells from Hogwarts. His Patronus charm could be a very useful tool in the often - dark and dangerous Dresden Files world. It could help him fight off some of the nastier creatures there. On the other hand, the wizards in the Dresden Files might view him with suspicion at first, not knowing exactly where his loyalties lie.

Severus Snape and Murphy from the Dresden Files. Snape has his cold, brooding exterior and complex past, while Murphy is a tough, no - nonsense police detective dealing with the supernatural. Their interactions could be very tense, with Snape looking down on Murphy's 'mundane' ways of dealing with magic at first, but later realizing she has her own strengths.

One idea could be a fanfic where a new character with a unique magical ability arrives in Chicago and has to team up with Harry Dresden. This new character could have an ability that even Harry has never seen before, like the power to manipulate time in small bursts, which causes all sorts of chaos and new challenges for them to face.

Well, in some fanfiction, we might see Anna and Kristoff visiting Hogwarts. They could be amazed by the moving staircases and magical creatures. In reverse, Harry, Ron and Hermione could end up in Arendelle. Hermione might be intrigued by the way Elsa controls her ice powers and try to find a scientific or magical explanation for it. Also, the Dementors from Harry Potter could be compared to the dark forces in Frozen 2, like the mist that Elsa has to face.

One interesting crossover could be the use of magic in the Avengers world. For example, Hermione could use her knowledge of spells to help the Avengers solve a problem that technology couldn't. Maybe she could use a spell to break through an impenetrable force field created by an enemy. Another aspect could be the Avengers characters learning magic. Tony Stark might be fascinated by the concept of magic and try to incorporate it into his technology. Or Thor could share his knowledge of Asgardian magic with the Hogwarts students.

One interesting crossover could be a scenario where Hermione uses her magic to help Elsa control her powers better. Maybe she creates a spell that can soothe Elsa when she's about to lose control.

In some fanfiction, Maleficent might team up with a dark wizard from the Harry Potter universe. They could combine their powers to try and take over both the wizarding world and the fairy - tale land where Maleficent comes from. This would create a complex power struggle with the heroes having to find new ways to combat them.

One interesting crossover could be the characters from Harry Potter visiting Narnia. For example, Harry, Ron, and Hermione might find themselves in Narnia through some magical accident. They could then interact with the talking animals and magical beings there, like how they interact with the magical creatures in their own wizarding world. Maybe they would help the Narnians in a battle, using their unique Hogwarts - taught magic.
