What could be an interesting plot for a Harry Potter x Hazbin Hotel fanfiction?

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.

Ron and Angel Dust. Ron is often the more down - to - earth and food - loving character in Harry Potter. Angel Dust, on the other hand, is flamboyant and has a wild side. Their differences could lead to some really comical and also heartwarming interactions. Ron could introduce Angel Dust to some wizarding world food, and Angel Dust could show Ron some of the unique and fun aspects of Hell's nightlife, while also learning about loyalty from Ron, which is something he might lack in his own life.

One idea could be exploring Lucifer's past before the events of Hazbin Hotel. Maybe show his rise to power and the decisions that led him to become the ruler of Hell. Another could be a story where Lucifer has to deal with a new, powerful demon who challenges his authority in Hell. A third idea might be a fanfiction that focuses on Lucifer's relationships with the other main characters in a more in - depth way, like his true feelings towards Charlie and how he views her plan for the hotel.

Maybe the Hazbin Hotel is in the middle of a crisis where the souls of the damned are being consumed in a strange and new way. Charlie and her crew suspect it has something to do with a portal that has opened up to a dimension filled with the kind of demons the Doom Slayer is used to fighting. They seek out the Doom Slayer, who has to navigate the politics and oddities of Hazbin Hotel's Hell while trying to close the portal and stop the consumption of souls.

One idea could be that God decides to visit the Hazbin Hotel to see if there's any hope for redemption among the demons. He could interact with Charlie and the other characters, causing them to question their beliefs and actions. Another could be a story where God sends an angel to the hotel undercover to observe and report back, and the angel ends up befriending some of the demons, blurring the lines between good and evil.

One idea could be an OC who is a fallen angel trying to redeem themselves in the Hazbin Hotel. They could face challenges from both the sinners and the hotel staff, adding an interesting dynamic.

One idea could be Adam's backstory exploration. Maybe he had a different life before coming to the Hazbin Hotel universe and that could be delved into. For example, his family, his upbringing, and how those things might have shaped his current self.

Well, a plot idea could be that Alastor discovers a new power within himself in the context of a fanfiction. This new power could either help or hinder his standing in Hell. Also, perhaps a plot where Alastor tries to start his own 'radio show' in Hell that's different from his usual broadcasts, and it causes all kinds of uproar among the demons. Or, what if Alastor is forced to team up with someone he really dislikes, like Vox, to face a common threat to their power in Hell?

One idea could be a human who ended up in Hell due to a deal gone wrong with a demon on Earth. They have to navigate the strange and dangerous world of Hazbin Hotel while trying to find a way to reverse their fate. Maybe they team up with some of the hotel's residents who see an opportunity in their unique situation.
