The magic in Harry Potter and the superpowers in Marvel can interact in really interesting ways. For example, a wizard's spell of invisibility could be compared to the powers of characters like the Invisible Woman in the Fantastic Four. However, the magic is more about incantations and potions, while Marvel superpowers are often more innate. In a harem fanfiction scenario, if a Harry Potter character like Fleur Delacour were in a relationship with a Marvel character like Wolverine, her Veela charm might have an unexpected effect on his berserker rage. It could either calm him down or make it more intense, depending on how the writer wants to play it.
One great 'Fem Harry Potter Marvel Crossover Fanfiction' is 'The Witch and the Shield'. In this story, the female version of Harry Potter finds herself in the Marvel universe. It has an interesting plot where she teams up with the Avengers. Her magic skills add a new dimension to their battles against villains.
One common trope is the 'fish - out - of - water' situation. The fem Harry Potter character is suddenly in a very different world like Marvel, and she has to adapt. Another is the power - comparison trope, where her magic is compared to the superpowers in Marvel. For example, how her ability to apparate might be better or different from Quicksilver's speed.
Wolverine and Hagrid would be an unexpected but cool crossover. Wolverine's tough and gruff exterior contrasted with Hagrid's big - hearted and gentle nature. Maybe Wolverine could help Hagrid with some dangerous creatures, using his combat skills and Adamantium claws.
One idea could be that the Deathly Hallows are actually Infinity Stones in disguise. Harry, Ron, and Hermione could team up with the Avengers to stop Voldemort and Thanos who have joined forces. The Marauder's Map could be used to track the villains across different dimensions.
One interesting storyline could be a magical item from the Harry Potter world ending up in the Marvel universe. For example, the Time - Turner. This could lead to all sorts of chaos as characters from both universes try to figure out how to use it or keep it from falling into the wrong hands. In the harem aspect, perhaps Hermione finds herself in the middle of a group of Marvel heroes who are all intrigued by her intelligence and magic. Another could be that a spell gone wrong in Hogwarts transports some of the students to the Marvel world. There, they meet the Avengers and other heroes, and some of the students start to form relationships with them, creating a harem - like situation.
I think Harry Potter and Spider - Man would be an interesting pairing. They are both young heroes with a strong sense of justice. Harry could teach Peter Parker about magic, and Peter could show Harry how to use his web - slinging skills in a more creative way in the wizarding world.
If Harry Potter was in the Marvel Universe, he'd probably end up at Xavier's School for Gifted Youngsters. Think about it, a school full of mutants with special powers, and here comes Harry with his wizardry. He'd either be a great asset or cause a bit of a stir. His magical abilities would be a new kind of power that the X - Men and other mutants might not be used to dealing with.
Well, I'm not sure of a specific one off the top of my head. But you could try searching on fanfiction platforms like Archive of Our Own. Just type in 'Harry Potter Marvel Vegas wedding' in the search bar, and you might find some interesting stories.
One great 'Marvel Harry Potter Fanfiction' is 'The Sorcerer's Avengers'. It combines the magic of Harry Potter's world with the superhero awesomeness of Marvel.
