What are some interesting plot ideas for Hazbin Hotel fanfic?

One idea could be Naruto somehow ending up in the Hazbin Hotel universe. Maybe he's on a strange mission and gets transported there. He could use his ninja skills to help the characters in the hotel deal with some of their problems, like fighting off demons that are causing trouble outside the hotel's protection. Another plot could involve the Hazbin Hotel characters visiting Naruto's world and being amazed by the different kind of powers and cultures there.

One idea could be that God decides to visit the Hazbin Hotel incognito to see if redemption is truly possible in this unique afterlife setting. He could interact with the characters like Charlie and Vaggie, observing their efforts and maybe secretly guiding them in subtle ways.

Another could be a story where they both have a falling out over a shared interest, like a powerful artifact in Hell, and then compete against each other in a series of challenges. A third idea is that they have to team up to face a common enemy, perhaps a new demon who is threatening their power and status in Hell.

One idea could be a story where Lucifer and Alastor have to team up to deal with a new threat to Hell.

They could start off not trusting each other much, but as they face challenges together, they begin to respect one another's abilities.

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.

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?

You could also write a fanfiction about a new character arriving at the Hazbin Hotel. This new character could have a unique power or a very different personality from the existing ones, which would create all sorts of new interactions and storylines. Maybe they have a special ability to see the pasts of the other characters and use that to help them on their path to redemption.
