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.
In some 'Harry Potter and Tony Stark' fanfiction, they might come together to face a common enemy. This enemy could be a threat that combines magic and technology, something neither the wizarding world nor Stark has faced before. Their different skills and knowledge would need to be combined. Harry's knowledge of spells and the magical realm, along with Tony's advanced technology and strategic thinking, would make for an exciting story.
One interesting crossover could be Tony Stark using his technology to help Harry Potter in the wizarding world. For example, he might create devices that can detect dark magic more easily. Another could be Harry Potter teaching Stark about magic, like how to use a simple spell to do something mundane but in a magical way. Maybe a levitation spell to move his tools around in the lab.
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.
One plot idea could be Harry's journey to discover his true heritage within the Stark family. Maybe he uncovers a long - lost secret about his father Brandon Stark that has been hidden for generations. Another could be his adventures in the North, facing the same challenges as the Starks before him, like dealing with the White Walkers or rival houses.
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.
Well, think about a scenario where the Philosopher's Stone gets stolen and taken to Asgard. Harry, Ron, and Hermione follow it there. Thor, initially suspicious of these strange wizards, eventually realizes they are on the same side. Together, they embark on a quest to retrieve the Stone, with Thor providing his brute strength and the Hogwarts gang using their wits and magic along the way.
One interesting crossover could be Darkseid's quest for the Deathly Hallows. Imagine him believing that these powerful magical artifacts could enhance his already great power. He might send his minions to Hogwarts to search for them, leading to a battle between the students and Darkseid's forces.
A possible crossover might involve Aragorn being magically transported to Hogwarts. He could be a bit bewildered at first by all the magic around him, but then he starts to adapt. He might end up training the students in physical combat skills, which are lacking in the wizarding world. Meanwhile, Harry Potter could be fascinated by Aragorn's tales of his adventures in Middle - earth and might even try to incorporate some of Aragorn's courage and honor into his own life.
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.
One interesting crossover could be the magical world of Harry Potter colliding with the Titan Shifter's world in a way that the wizards have to face the Titans. Maybe the Titans are immune to some magic spells, creating a huge challenge for the Hogwarts students and professors. For example, Hermione could be researching ways to counter the Titans' abilities using her vast knowledge of magic.
