What could be the plot of a Harry Potter x Tony Stark crossover fanfiction?

One possible plot could be that Tony Stark, with his technological genius, somehow discovers the wizarding world of Harry Potter. He might be intrigued by the magic and try to find a way to blend his technology with it. For example, he could develop a device that can detect magic or even try to create a new form of energy using magic. Harry Potter and his friends could be both amazed and a bit wary of Tony's advanced technology.

Maybe Harry travels to the Marvel universe and tries to learn from Tony Stark. He could be interested in Stark's technology for some reason related to fighting Voldemort, like using it to detect Death Eaters.

One possible plot could be that Tony Stark discovers a way to travel to the wizarding world. He meets Harry Potter and they initially have a bit of a culture clash. But then, they realize they can learn a lot from each other. Tony helps Harry with some Muggle - like technology problems in Hogwarts, like improving the communication systems. And Harry shows Tony the wonders of magic, like how to use a Patronus to fight off Dementors that somehow end up in Stark Tower.

A third idea is a scenario where both universes are somehow merged. In this new world, Hogwarts students have the option to study both magic and technology. Harry and Tony meet as teachers or mentors in this new educational system. They have to work together to prevent the misuse of both magic and technology by some of the more power - hungry students or villains.

One plot idea could be that Tony Stark somehow travels to the wizarding world. He could use his technological knowledge to improve the wizarding devices. For example, he might make brooms fly faster with some kind of engine modification.

Perhaps the plot could start with their unusual upbringing. Harry grows up with the Dursleys while Tony has his own issues with his father. They both develop their unique skills. When they meet, they realize they are brothers. They then start to combine magic and technology. For example, they could use magic to enhance Tony's suits or use technology to create new magical artifacts. Along the way, they face challenges from those who oppose the mixing of these two very different worlds, like some traditional wizards who don't trust technology and some tech - moguls who fear magic.

Well, it could be that Fem Harry Potter uses her magic skills in Tony Stark's high - tech world. Maybe she helps him develop new technologies that combine magic and science. For example, she could use spells to enhance the power sources of his Iron Man suits, or use her knowledge of potions to create new substances for his experiments.

Well, one possible plot could be that Fem Harry Potter, with her magical abilities, somehow gets transported to the Marvel universe. Tony Stark, being the curious and brilliant man he is, is intrigued by her magic. They start working together on some sort of project, perhaps to combine magic and technology. As they spend more time together, they develop feelings for each other and eventually get married. Their relationship might face challenges from both the magical and non - magical sides, like some wizards not trusting the technology - based Avengers and some Avengers being skeptical about magic.

Well, in fanfiction, anything can be possible. It could be that some sort of magical time - space rift or a powerful spell gone wrong brings Harry Potter into the world of Tony Stark. Maybe a wizard in the Potterverse messes up a spell and accidentally transports Harry to the Marvel universe where he is then adopted by Tony Stark.

Well, it could work in a magical way. Maybe Harry's magical abilities could be combined with Stark's technology. For example, Harry could use magic to enhance Stark's suits, like making them invisible without the need for technology. And perhaps they could fight together against villains who are a threat to both the wizarding world and the world of technology.
