In a fanfiction, the Hogwarts houses could be related to different areas or groups in Hazbin Hotel. Gryffindor could be associated with the more heroic and brave demons in the hotel, while Slytherin could be linked to the more cunning and power - hungry ones. The magic that each house is known for could then be applied in different ways within the context of the hotel's setting. For example, the loyalty and friendship magic often associated with Hufflepuff could be used to heal the broken relationships among the demons in the hotel.
Well, you could have spells from Harry Potter work in the Sekirei world in unique ways. For example, the Wingardium Leviosa spell could be used to levitate Sekirei during battles, giving them an unexpected advantage. Or the Imperio curse could be modified to control certain non - sentient elements in the Sekirei world, like the mechanical devices that are sometimes part of the Sekirei battles.
The magic in Harry Potter is very diverse. In the Iron Throne setting, it could be used for various things. Spells like 'Accio' could be used to retrieve valuable items like swords or crowns from afar. 'Wingardium Leviosa' could be used in battles to disarm opponents or move large objects like catapults. However, the use of magic would probably be seen as a huge threat by many in the Iron Throne world who are used to more traditional forms of combat and power - seeking.
Well, in fanfiction, you could have Harry's magic interact with the Incredibles' superpowers in a fight. For instance, if they were facing a common enemy. Harry could use spells to enhance the Incredibles' powers. His levitation charm on Mr. Incredible could make him jump even higher and land more powerfully.
It also keeps the interest alive during the wait for new official content. When there's a long gap between new episodes or developments in the official Hazbin Hotel story, these fanfictions give fans something to enjoy. They can explore new storylines and ideas that are inspired by the original but still have their own unique twists, like a fanfic where the characters react to a time - travel scenario.
Well, it can be as simple as a wizard using a spell to hack into a magical device. For example, a spell that allows them to bypass the security enchantments on a powerful magical artifact. It's like using magic as the tool for hacking in the wizarding world.
One idea could be that the characters from Hazbin Hotel end up in the wizarding world of Harry Potter. Charlie could try to reform some of the dark wizards using her methods from the hotel. For example, she might see Voldemort as a 'lost soul' and attempt to rehabilitate him, which would create a really unique dynamic as the other Hogwarts characters react to her unorthodox approach.
One idea could be that some of the Hogwarts students accidentally end up in Hell and have to find their way back with the help of the Hazbin Hotel crew. Maybe they could exchange magic knowledge for help in navigating the strange and dangerous underworld.
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.
One way is to have a magical accident. Maybe a wizard in the Harry Potter universe was experimenting with interdimensional travel and accidentally brought Vegeta and Piccolo to the stadium in the wizarding world. Then they all have to figure out how to get back to their own worlds while dealing with the chaos that ensues in the stadium, like angry fans or other magical creatures that are attracted to the strange energy.
Often, the wizards might have to hide their magic in the Ouran setting. This creates a lot of interesting scenarios. They might accidentally use magic when they're flustered or in a tight spot. And then they have to cover it up, which can lead to some really comical or tense moments in the fanfic.
