Perhaps Brandon Stark, while in one of his visions, sees a boy with a lightning - shaped scar on his forehead. Intrigued, he tries to find out more and through some magical or supernatural means, a portal opens up and Harry Potter steps through. This encounter in the Stark's territory would be the beginning of an unexpected friendship and a series of events that would change both their worlds.
It could start with Harry having a strange dream about a cold, snowy land filled with direwolves. He wakes up curious and through some magical accident, ends up in the world where Brandon Stark lives. This sudden appearance in a new world full of different rules and politics would be the starting point of their adventure together.
In the normal 'Harry Potter' and 'Game of Thrones' universes, there is no such connection. But in some wild and creative fanfiction, it could be possible. Fanfiction often bends and twists existing universes to create unique and unexpected relationships. However, this is not part of the official lore of either series.
If in fanfiction Harry Potter was Brandon Stark's son, it would create a very strange and interesting mix of magic and medieval politics. The wizarding world of Harry Potter has its own set of rules regarding magic and society, while the world of Brandon Stark is filled with power struggles, wars, and complex family dynamics. There would be a clash between the two cultures. For example, how would the people of Westeros react to magic? And how would the wizarding world view the violent and often cruel world of Westeros? It would be a wild ride for the story.
The fanfiction could start at Hogwarts. One day, a new group of students arrives, and they turn out to be Jon Stark's sisters. Harry Potter is immediately intrigued by their different ways and their connection to a world he doesn't know much about. They start talking, and from there, the story kicks off as they explore each other's worlds and secrets.
One interesting crossover could be a story where Harry Potter uses his magic to travel to the world of Brandon Stark. Maybe he helps Brandon in his struggles against the White Walkers using spells and potions. For example, he could use a warming charm to protect the Stark soldiers from the cold of the North.
Tony Stark would likely raise Harry Potter with a focus on intelligence and innovation. He'd encourage Harry to think outside the box when it comes to magic. Maybe he'd set up a lab for Harry to experiment with magic and technology combinations.
Tony would raise Harry with a focus on intelligence and self - reliance. He'd encourage Harry to study hard, not just in school but also in understanding the world around him. Harry would be trained in physical combat and how to use technology to his advantage.
Harry would likely be in awe of Tony's technology at first. Tony, on the other hand, would be curious about Harry's magic. They might start off a bit wary of each other, but as they realize they both have a strong sense of justice, they would begin to work together. For example, Tony could help Harry understand the principles of engineering, and Harry could show Tony some basic spells.
It depends on the situation. In the wizarding world, Harry Potter would be more powerful as he can use magic which is a fundamental part of that universe. He can cast spells to defeat enemies, protect himself and others, and manipulate the environment around him.
A possible start could be a prophecy in both the wizarding world and Asgard. The prophecy foretells of a great danger that can only be averted if a wizard from Hogwarts and a warrior from Asgard join forces. Harry Potter and Thor are then made aware of this prophecy and set out on a journey to find each other and figure out how to stop the impending doom.
It could start with a magical accident in the Harry Potter world. For example, a spell gone wrong during a Hogwarts class creates a portal that sucks Harry into the world of One Piece, right onto Whitebeard's ship. The crew is initially suspicious but Whitebeard, sensing something different about Harry, decides to let him stay for a while.
