Well, perhaps there's a plot where the two worlds start to merge in some strange way. Tony Stark is intrigued by the magic seeping into his world and starts to investigate. He crosses paths with Harry Potter who is also trying to figure out what's going on. They join forces. Harry teaches Tony some basic spells to protect himself, and Tony gives Harry some cool gadgets. As they work together, they form a deep friendship and together they manage to stop the merger from causing chaos in both their worlds.
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.
One possible plot could be that Tony Stark, through some magical accident, ends up in the wizarding world of Harry Potter. He might use his tech - savvy mind to try and understand the magic there. Maybe he tries to combine his technology with magic, like creating a magical - tech hybrid broomstick that can fly faster and has built - in defense mechanisms. He could also help the Hogwarts students with his engineering skills, for example, improving the castle's security systems using a combination of magic and 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.
Yes, they can. Fanfiction often plays with crossovers. Tony Stark, a brilliant inventor from the Marvel universe, and Harry Potter, a powerful wizard, could form an unlikely friendship. For example, Tony could help Harry with some advanced Muggle technology to enhance the security at Hogwarts, while Harry could introduce Tony to the wonders of magic, like using magic to repair damaged Iron Man suits quickly.
One possible plot could be that a magical portal opens up and Harry Potter is accidentally transported to the world of Eddard Stark. There, he has to hide his magical abilities while trying to find a way back home. Along the way, he gets involved in the political intrigue of Westeros, and Eddard Stark becomes suspicious of this strange boy with unusual powers.
Perhaps in the fanfiction, Arya Stark is a wizard from a long - lost magical family in Westeros. She travels to Hogwarts to learn more about magic. There, she meets Harry Potter. They start off as rivals, competing in magical duels and academic achievements. But as time passes, they realize they have more in common than they thought. When dark forces start to threaten Hogwarts, they combine their skills, Arya's quick thinking and combat skills with Harry's knowledge of magic and experience with the dark arts.
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.
Yes, there are some out there. You can start by looking on fanfiction websites like Archive of Our Own. Just search for the specific pairing 'Tony Stark x Harry Potter friends' and you'll likely find a variety of stories with different takes on their friendship. Some might focus on them teaming up in a magical - technological adventure, while others could explore how they'd interact in a more modern - wizarding world mash - up setting.
One possible plotline could be that through some magical - technological mishap, Tony Stark ends up in the Harry Potter universe and somehow becomes pregnant. Maybe he has to deal with the magical world's reaction to this very un - magical situation while also trying to find a way back to his own world. Another could be that a spell or some new technology allows for a cross - universe connection that results in the mpreg situation, and then it's about how the two characters from different worlds navigate this new reality together.
They could go on a quest to find a magical - technological hybrid artifact. The two of them would use their unique skills. Tony would use his tech to analyze the magical elements and Harry would use his magic to navigate through the enchanted areas they might encounter.
