In a fanfiction, the characters from Stranger Things could have different roles. The Byers family might have a hidden magical heritage that was dormant until the events of Stranger Things. Jonathan could be a talented wizard photographer, using magic to enhance his pictures and capture magical creatures. Nancy could be a fearless journalist in the wizarding world, uncovering secrets about the connection between the Upside Down and certain dark magic. The kids would be sorted into different houses based on their personalities. Eleven might be in Ravenclaw for her intelligence and unique powers, while the boys could be in Gryffindor for their bravery in facing the Upside Down.
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.
Well, consider this. The Upside Down in Stranger Things could be a result of some dark magic from the Marvel universe. The Stranger Things characters, being the only ones who know about it, are recruited by Doctor Strange. Eleven could be trained by Strange to better control her powers and use them in a more magical way. The other kids could learn about different dimensions from Strange and use that knowledge to help protect the Marvel universe from threats that might be coming from the Upside Down.
Well, in some fanfictions, Eleven could be sent to Hogwarts by mistake. Since she has telekinetic powers, the wizards might initially be very confused and intrigued by her abilities. She could form an unlikely friendship with Hermione, as both are very intelligent and resourceful. And then there's the idea of the Demogorgons being related to some dark magic creature from the Harry Potter universe, and the two sets of characters have to figure out how to defeat them together.
The characters from 'Shameless' are known for their scrappy and street - smart nature. In the 'Harry Potter' world, they could be Muggles who accidentally discover the wizarding world. For example, Carl could be exploring an old abandoned building and find a hidden passage to Diagon Alley. Or they could be Squibs related to some important wizarding families. Like Veronica could be a Squib who has always felt out of place in the Muggle world and finally finds a sense of belonging in the wizarding world's fringes.
The characters could be trainers. Harry, for example, could start his Pokemon journey in a region similar to Kanto. He might choose a Charmander as his first Pokemon, just like how he was drawn to the Firebolt in the original series. Ron could be more interested in food - related Pokemon like Snorlax. Hermione would be the type to research every single Pokemon and their abilities thoroughly before choosing her team. They could use their magic skills in a different way, like using spells to communicate with Pokemon or to enhance their Pokeballs.
Harry Hook often fits in as an alternate version or a new character added to the existing Harry Potter universe in fanfiction. He can bring new storylines and interactions.
One idea could be that the Demogorgon from Stranger Things somehow finds its way into the wizarding world of Harry Potter. The Hogwarts students, with their magic, have to figure out how to stop it. Another could be that Eleven has some latent wizarding abilities and she gets a letter from Hogwarts, then has to navigate both the Upside Down and the magical world.
One idea could be that the Demogorgon from Stranger Things somehow enters the wizarding world of Harry Potter. The students at Hogwarts have to use their magic to fight it. Another idea is that Eleven has some sort of magical connection to the wizarding world and she gets a letter from Hogwarts. Maybe she could learn magic there and use her powers in combination with spells.
One idea could be that the Demogorgon from Stranger Things somehow finds its way into the wizarding world of Harry Potter. The Hogwarts students would be both terrified and intrigued. They might initially try to use magic spells like Stupefy or Protego to fend it off. Hermione would probably be the first to start researching about this strange new creature, while Harry and Ron would be more on the front lines, trying to keep their classmates safe. The Stranger Things kids could also be magically transported to Hogwarts. Dustin would be amazed by all the magical creatures and would want to study them, Eleven might use her powers in new and unexpected ways in the wizarding world, like trying to communicate with magical portraits or using her telekinesis to move magic wands.
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.
Well, Hermione could use her vast knowledge of magic to help solve some of the problems in Hotel Transylvania. For instance, if there was a magical malfunction in the hotel's systems, she could probably figure out a spell to fix it.
