In the realm of fanfiction, this could be due to a complex web of events. Maybe Tony Stark was secretly a wizard all along, but his scientific pursuits in the Muggle world (or rather, the non - wizarding part of the Marvel universe) overshadowed his magical abilities. He could have had an encounter with Harry Potter's mother in a hidden corner of the multiverse where magic and technology coexist. Their relationship led to Harry's birth, and the story could explore how Harry's life would be different with a genius - inventor - father from a completely different world.
Well, in fanfiction, anything can happen. It could be that some sort of cosmic entity decided to play a joke and made Tony Stark Harry Potter's father. Perhaps Stark was involved in an experiment that opened a portal to the wizarding world and he had a relationship there without realizing the implications at first. Then, through a series of events, it was discovered that he was Harry's father. It's all about creativity and bending the rules of the original universes.
One possible plotline could be a crossover in an alternate universe where Harry Potter's father, James Potter, and Tony Stark meet. Maybe they are brought together by some magical - technological mishap. Stark could be intrigued by the magic that James wields and they end up working together to solve a problem that threatens both the wizarding world and the world of technology.
Well, first of all, it would probably involve a lot of secrecy at the beginning. Harry might find some strange artifacts or clues that lead him to suspect that his father is not who he thought. Once he discovers the truth, Tony Stark would probably want to protect Harry in his own way, which could be very different from how the wizarding world does it. He might introduce Harry to new forms of combat using his Iron Man suits. And there would be a whole subplot about how the wizarding community reacts to having an outsider like Tony Stark be related to one of their most famous wizards. There could be jealousy, suspicion, and also a lot of excitement as they see the potential of combining magic and technology.
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.
James Potter was a popular and somewhat cocky young wizard. Tony Stark, the billionaire genius. They could clash in terms of their egos. But at the same time, they could also work well together. James' loyalty to his friends and his sense of justice could be something that Stark admires. And Stark's ability to think outside the box and his vast resources could be appealing to James. For example, in a fight against a powerful dark wizard - tech villain, James' magic combined with Stark's high - tech gadgets could be a formidable force.
One way it could happen is through the power of the Time - Turner. Harry could use it to go back in time and prevent the event that injured Tony Stark in the first place. Or he could take Tony to Hogwarts where the advanced magic and potions could be used to heal him. The magic potions like the Felix Felicis could be given to Tony to enhance his chances of a speedy recovery, and the healing spells of Madam Pomfrey could also be very effective.
There are quite a few out there. In some fanfictions, Tony Stark, with his genius intellect, tries to solve the mysteries of the wizarding world that Harry Potter's father was a part of. It often involves Stark mentoring Harry, sharing his knowledge of science and engineering, while Harry teaches Stark about magic. A popular one has Stark building a magical - tech interface that helps Harry defeat Voldemort more easily.
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.
Well, one way could be through some sort of multiverse concept. Maybe in a particular alternate universe, the magical and technological realms collide in a way that allows for such an unlikely family connection. It could involve a powerful spell or some advanced Stark technology that messes with the fabric of reality and ends up creating this strange but interesting scenario where Harry Potter is reimagined as Tony Stark's daughter.
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.
One possible plotline could be that a powerful magical spell in the Harry Potter universe somehow crosses over and affects Tony Stark, causing the mpreg situation. Then, the story could revolve around Tony trying to figure out what happened and how to reverse it, with Harry Potter characters helping or hindering him. Another plotline might be that a new form of technology in Tony Stark's world has an unexpected side effect when combined with the magic of Harry Potter's world, leading to the mpreg. And the characters have to find a way to deal with the social and magical/technological implications.
