The characters could be assimilated into the different castes. For instance, Hermione might be placed in the intellectual caste, but she would resist the restrictions placed on her freedom of thought. Harry, with his natural leadership and rebellious nature, would be at odds with the conformist society of 'A Brave New World'. Ron, on the other hand, might struggle with the lack of family - like bonds in the new society as it focuses more on the collective.
In a fanfiction, the characters from Harry Potter could be introduced to the 'A Brave New World' through a magical accident. Harry might be seen as a threat to the stability of the new society because of his ability to inspire others. Hermione could be fascinated by the scientific advancements in 'A Brave New World' but also horrified by the lack of individual freedom. Ron could provide a bit of comic relief while also being a voice of reason, asking the tough questions about why this new society is so wrong in its treatment of people, and together they could try to change the 'Brave New World' for the better.
The characters might be reimagined with different values. For instance, Hermione could be more conflicted about her pursuit of knowledge. In 'A Brave New World', knowledge is often restricted based on one's social caste. So in this fanfiction, Hermione might face more opposition when she tries to access certain books or magical knowledge. She could start to question whether her thirst for knowledge is really a good thing in this new, more controlling magical society.
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.
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.
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.
One way to blend them creatively is through character crossovers. Imagine a character from 'Brave New World' like John the Savage finding himself in the wizarding world of 'Harry Potter'. His different upbringing and values would create interesting conflicts. For example, he might be shocked by the use of magic as it goes against the highly controlled and technological society he comes from. He could question the hierarchical system in Hogwarts which, although different from his own world, still has a sense of order that he might not fully understand or accept.
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.
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 wolf animagus could be seen as an outsider in the Twilight werewolf packs. They might initially be seen as a threat because their form of transformation and magic is so different. For example, the Twilight werewolves transform based on the moon and their tribal heritage, while a wolf animagus can transform at will through magic.
