Harry could be seen as a strange but powerful being. His Gryffindor courage would be respected in Asgard. Hermione might be seen as a great scholar, like the Asgardian mages. Ron could be the loyal friend who has to adapt to the grandeur of Asgard.
The Weasley twins could introduce their pranks to Asgard, causing some chaos but also some laughter. Dumbledore could be seen as an ancient and wise figure similar to Odin in some ways. Harry, with his lightning - shaped scar, might be thought to have some connection to Thor's lightning powers at first glance.
A Harry Potter and Asgardian fanfiction could be really exciting. It might involve Harry Potter being magically transported to Asgard. There, he could learn about the Asgardian magic and culture. Maybe he would meet Thor and they would go on an adventure together to fight some dark force that threatens both the wizarding world and Asgard.
One possible plot is that Voldemort somehow has a connection to an Asgardian villain. Harry, being the hero, travels to Asgard to find a way to defeat Voldemort once and for all. Along the way, he meets the Asgardian gods. They initially doubt him but soon realize his strength. Harry then combines his wizardry with Asgardian magic to face the dual threats of Voldemort and the Asgardian foe.
One interesting plot idea is when the magic systems of Asgard and Hogwarts collide. For example, the use of seiðr (Asgardian magic) in the wizarding world of Harry Potter. Another is characters from Asgard attending Hogwarts. Imagine Loki causing chaos in the halls of Hogwarts or Thor trying to fit in with the wizards.
Angel Dust would be a bit of a wild card. His flamboyant personality and his own set of skills (like his combat abilities) could get him into all sorts of trouble and also some interesting situations. He might befriend the Weasley twins, getting involved in their pranks but also teaching them a thing or two about his own brand of chaos. Husk, on the other hand, would likely just try to find a quiet corner in the Hogwarts library or the Three Broomsticks and avoid most of the hubbub, but would be dragged into things against his will from time to time.
A plot could revolve around a prophecy that involves both the wizarding world and Asgard. Harry is the key figure in the prophecy. He travels to Asgard to find out more. There, he meets Odin who initially distrusts him. But as Harry proves his worth through his magical abilities and courage, Odin decides to help him. Together, they must face a common enemy that is emerging due to a dark magic that is seeping between the two worlds. Harry could also form a friendship with Sif, who teaches him some Asgardian fighting techniques.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often tags related to 'Asgardian' and 'Harry Potter' which can help you filter out the relevant stories. Another option is FanFiction.net, though the tagging system might be a bit different. Just search for the key terms and explore the results.
The Stranger Things characters would bring their own unique personalities and skills. For example, Joyce could be like a Muggle mother figure who somehow gets involved in the wizarding world and helps out with her no - nonsense attitude. Hopper could be an Auror - like figure, using his investigative skills to track down dark wizards or creatures that have a connection to the Upside Down. The kids would have to adapt to the rules of Hogwarts, but also introduce their own ideas. They might not be used to using wands, but they could find ways to incorporate their own abilities with magic, like using Eleven's powers to enhance a spell or something.
The Hogwarts professors could also play important roles. Dumbledore could be seen as a wise old figure, much like Rafiki. He could offer guidance to the animals and the Harry Potter characters alike. Snape, on the other hand, might be a bit more difficult to place, but perhaps he could be a sort of protector in the shadows, using his potions knowledge to help heal any injured animals or deal with magical threats in the Pride Lands.
Neville Longbottom could befriend Mia in fanfiction. Neville, with his new - found confidence in the later Harry Potter books, could teach Mia about being brave and standing up for herself. He could also share his knowledge of plants, and they could start a garden together in the Genovian palace grounds. This would not only be a cute friendship but also a way to blend the two different worlds of the two series.
In an Asgardian setting, Hermione's character would develop in many ways. First, she would have to adapt to a new culture with different values. Asgardians value strength and honor in a different way than wizards do. This would make her reevaluate her own beliefs. Also, being around powerful Asgardian warriors would inspire her to train physically. Her intelligence would still be a great asset, but she would learn to combine it with physical prowess. She might start to see magic not just as a tool for learning and problem - solving but also as a weapon in a more direct sense. And she would probably become more confident in her own abilities as she proves herself in this new and challenging environment.
