One interesting fanfiction could be about Angel Dust's backstory before arriving at the Hazbin Hotel. It might explore his life in Hell and how he got involved in certain activities. Another could be a story where Angel Dust forms an unlikely friendship with one of the other hotel residents, like Charlie. And there could also be a fanfiction that focuses on Angel Dust's attempts to redeem himself in a really unique and unexpected way.
One idea could be a story where Lucifer and Alastor have to team up to deal with a new threat to Hell. Maybe a powerful demon from another realm is trying to take over, and they have to put aside their differences. They could start off not trusting each other much, but as they face challenges together, they begin to respect one another's abilities.
There's a fanfiction where Angel Dust time - travels back to a crucial moment in his past. This gives him the chance to change a major decision that led him to his current situation in Hell. It's unique because it plays with the concept of fate and self - discovery in a really interesting way.
In Hazbin Hotel fanfiction with Alastor x Reader, Alastor is often depicted as a complex character. He's charming yet menacing. His radio - themed appearance and mannerisms add to his allure. He's a powerful demon, and in these fanfictions, his relationship with the reader can range from a dangerous flirtation to a more protective bond.
I think Niffty would be an interesting character to pair with Alastor. Niffty is always cleaning and being hyper - active, and Alastor could either find this endearing or extremely annoying. Their dynamic could be quite comical. Also, Husk could be paired with Alastor. Husk is a grumpy alcoholic and Alastor's attempts to either annoy him further or get him to do something useful could lead to some engaging storylines.
Well, themes like self - discovery are often present. When Alastor is hurt, he has to reevaluate who he is and what his place is in Hell. There's also the theme of friendship or lack thereof. Some fanfictions explore how other characters either support or abandon him when he's in pain. And of course, there's the overarching theme of pain itself, both physical and emotional, and how Alastor copes with it. It can be through denial, anger, or acceptance, depending on the story.
There are fanfictions that focus on Alastor's relationships. For example, a story might explore a friendship or rivalry with Angel Dust. It could show how their different personalities clash or complement each other. Some fanfictions also like to put Alastor in situations where he has to face his own morality, even though he's a demon, and how he navigates those complex emotions within the context of the Hazbin Hotel world.
One common theme is the power dynamic. Alastor being a powerful demon and the reader usually being a more ordinary (by Hell's standards) character. Another is the idea of redemption. Maybe the reader tries to 'redeem' Alastor in some way. Also, there's often a theme of mystery, as Alastor has many secrets.
