What are some interesting plot ideas for a Harry Potter x Spiderman fanfic?

One idea could be a story where Spiderman has to team up with his greatest enemies to fight a new, more powerful threat from outer space. This would force him to put aside his differences and find common ground with the likes of Doctor Octopus and Green Goblin.

Gabriel could be an exchange student from a far - flung wizarding school. He brings with him a different style of magic. Harry Potter is both curious and cautious about him. As they study together, they find out that a series of strange magical occurrences around Hogwarts are related to a curse from Gabriel's home school. Together, they try to break the curse while also learning about the cultural differences in magic, which enriches their own magical understanding.

One idea could be that the main character from Reborn is reborn into the Harry Potter world as a wizard with his unique skills. He could use his combat abilities from Reborn to face the dark wizards in the wizarding world. Another could be that a character from Harry Potter gets reborn in the Reborn universe and has to adapt to the different rules and powers there.

Another plot idea is that some of the characters from Harry Potter, like Hermione, are transported to Narnia. There, they meet Aslan and learn about his world. Meanwhile, Aslan could send some of his Narnian creatures to the wizarding world to help Harry and his friends in their fight against the dark forces. This exchange of cultures and magics could create a really engaging story.

One idea could be that Spiderman discovers Rachnera in a part of the city that's been affected by some strange scientific experiment gone wrong. He initially mistakes her for a villain but soon realizes she's just trying to find her way in this new world. They could team up to fight against the real bad guys who are behind the experiment.

One plot idea could be that Spiderman and Silk team up to face a new super - villain who has the ability to manipulate time. They have to use their combined skills and their unique spider - sense in different ways to outwit the villain. Another could be a story where they explore their relationship more deeply while on a mission in an alternate dimension.

Another plot could involve a mad scientist who creates a device that can drain the powers of superheroes. He first targets Superman, but Spiderman gets involved when he sees the chaos in Metropolis. As they try to stop the scientist, they discover that the device has a side effect of giving the heroes new, unexpected powers for a short time. They have to quickly learn to control these new powers while also dealing with the main threat.

One plot idea could be that Spiderman and Mantis team up to fight a new villain in the city. Mantis uses her empathic abilities to sense the villain's motives, while Spiderman uses his webs and strength to physically combat the foe. Another could be a story where they get accidentally transported to an alternate dimension and have to work together to find their way back home. They might face strange new enemies and allies in this dimension.

Perhaps there could be a situation where the boundaries between the wizarding world and the world of Greek gods start to break down. Harry and Percy find themselves in a strange new world that is a mix of Hogwarts and Camp Half - Blood. They must figure out how to restore the boundaries while also dealing with the internal politics of both worlds. There could be some interesting character interactions, like Hermione trying to understand the Greek mythology and Annabeth being fascinated by the magic spells.

One idea could be that Jacob, with his werewolf abilities, somehow gets transported to the wizarding world of Harry Potter. He could team up with Harry and his friends to fight against a new dark force that combines the magic of the wizarding world with some sort of werewolf - related dark magic. For example, a group of dark wizards might be trying to use werewolf blood to create a new and powerful form of dark spellcasting.
