In a fanfic, Harry Potter might join forces with Doctor Strange. They could exchange knowledge of different forms of magic. Harry could teach Strange about Hogwarts magic, while Strange could introduce Harry to the mystic arts of the Marvel Universe. They could then combine their powers to defeat powerful enemies like Dormammu or Voldemort if he somehow ended up in the Marvel world too.
If Harry Potter were in the Marvel Universe, he might be a bit of an enigma to the superheroes at first. His magic doesn't follow the same rules as the superpowers they're used to. However, his loyalty and courage would quickly earn him respect. He could use spells like the Patronus to ward off dark forces, and his ability to speak Parseltongue could come in handy when dealing with snake - like villains or creatures in the Marvel realm.
Well, he could use his magic to help the Avengers in battles. Maybe he could use a spell to disarm Thanos of the Infinity Stones. His broomstick flying skills would also be useful for quick getaways or aerial attacks.
One idea could be that Harry would use his magic skills to help the Fellowship in different ways. For example, he could use his Patronus to ward off the Nazgûl, as his Patronus is a powerful form of positive magic. Another possibility is that he would have an interesting interaction with Gandalf, two powerful wizards from different magical worlds coming together.
In fanfiction, Harry as the Master of Death could also start a new school of magic in the Marvel universe. This could attract both mutants and regular humans with an aptitude for magic. It would be a place where they could learn about the different aspects of magic, especially those related to life and death. This would not only expand the magical community in the Marvel universe but also create a new generation of heroes and magic - users who have a different understanding of death and its implications.
In a fanfiction scenario, Harry Potter in the Game of Thrones world might be seen as a threat by the maesters. They might try to either study him or get rid of him. Harry, on the other hand, could form alliances with some of the outcasts like the Wildlings. He could teach them some basic magic for self - defense, which would change the dynamic of their relationship with the rest of Westeros.
Another possibility is that a Marvel hero, say Spider - Man, accidentally ends up in Beach City. He teams up with Steven to deal with a local threat that is also related to some sort of interdimensional chaos. For example, a group of villains from the Gem world and the Marvel world are working together to open portals to other dimensions to steal valuable resources. Steven and Spider - Man would have to use their unique abilities to stop them.
It could lead to all kinds of chaos. The Joker's unpredictable and chaotic nature might throw the Marvel heroes for a loop.
It's an interesting concept. In a Marvel fanfic where Harry Potter has teleported, he might find himself in the middle of a battle between the Avengers and some powerful enemy. His magic could potentially turn the tide of the battle. For example, his invisibility cloak could give the heroes an advantage in a stealth mission. Or his Patronus charm could be used to fight off some dark and negative forces that the Marvel villains might possess. It would be a very unique crossover, full of possibilities for new storylines and character interactions.
Well, he might join the Avengers. Imagine Harry using his magic skills alongside Iron Man's tech. It could be a really cool combination. He could use spells to enhance the team's defenses or help in battles in ways the regular Avengers couldn't. Maybe he'd have some clashes with Doctor Strange at first, since they both deal with magic, but then they'd probably end up working together.
In a Harry Potter fanfic with the Infinity Stones, the Stones could interact with the existing magical artifacts in interesting ways. The Elder Wand, for example, might have some sort of connection or reaction with the Infinity Stones. Wizards and witches who were already powerful, like Dumbledore, would have to figure out how to deal with these new and extremely powerful elements in their world. It could also lead to new forms of magic being discovered as the Stones' powers merge with the magic already present in the Harry Potter universe.
He'd probably have a more comical approach to magic. Mystery Inc. has its humorous moments, and that could influence how Harry uses magic. Instead of just using spells for serious things, he might use them in a more fun and creative way, like creating magic tricks to amuse his friends or to outwit his enemies.
A fanfiction could revolve around a spell gone wrong in the Harry Potter world that accidentally transports Ms Marvel there. She then has to navigate the wizarding world while also trying to find a way back home. Along the way, she teams up with Hermione to study the magic that brought her there and in the process, they learn from each other's worlds.
