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.

One possible plot could be that the Doom Slayer somehow ends up in the Hazbin Hotel universe. He might initially be seen as a threat due to his violent nature. But then, they realize he could be an asset in dealing with some of the more dangerous demons in the Hazbin Hotel world. For example, he could help Charlie and her crew deal with some of the more unruly and powerful demons that are causing trouble in and around the hotel.

One possible plot could be that the Doom Slayer somehow gets teleported to the Hazbin Hotel universe. He then has to deal with the demons there, which are different from the ones he usually fights. The hotel staff might initially be afraid of him, but then realize he could be an asset in dealing with more malevolent demons.

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.

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.

Well, a plot could involve Adam being sent on a mission by some other powerful entity in Hell to infiltrate the Hazbin Hotel and disrupt Charlie's plans. However, he ends up falling for Charlie and has an internal struggle between his loyalty to his original mission and his newfound feelings. Or perhaps Adam has a special power that Charlie needs to help with a big event at the hotel, like a demon - friendly concert, and they have to work together closely to make it a success.

One plot idea could be Lucifer seeing a different side of Adam that no one else has. Maybe Adam shows kindness towards a lower - class demon, which makes Lucifer question his own views. Another could be that they team up to solve a mystery in Hell that threatens both the sinners and the native demons. And a third idea is that Adam tries to introduce Lucifer to more 'human' concepts like forgiveness, which Lucifer initially resists but gradually comes to understand.

A possible plot for Hazbin Hotel Alastor x Charlie fanfiction is that there is a new threat to the hotel, a powerful demon who wants to shut it down. Alastor and Charlie must put aside their differences and work together to stop this threat. Alastor could use his radio - based powers to gather information and Charlie could use her charm to convince other demons to help them. Along the way, they might start to develop deeper feelings for each other as they see sides of each other they hadn't noticed before. Another idea is that Charlie tries to teach Alastor about modern technology and it leads to some really funny and endearing moments between them, all while they are also dealing with the day - to - day operations of the hotel.

Perhaps Adam has a special power that could either help or hinder Charlie's plans for the hotel. They could go on an adventure together to find a way to use his power for good. Along the way, they face various challenges that force them to rely on each other. This shared experience brings them closer and they start to fall in love as they realize how much they mean to one another.
