Sure, there is. However, its distribution and accessibility might vary depending on the region and the platform. Sometimes, it could be a limited release or exclusive to certain comic conventions.
Sure was! The concept of Hazbin Hotel first emerged in the form of a comic. This laid the foundation for its expansion into different creative outlets.
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.
Definitely not. Fanfiction should be a creative outlet that respects the source material and its audience. Sexual fanfiction based on 'Hazbin Hotel' violates these principles. It can lead to a negative perception of the fan base and may even cause legal issues for those who distribute or promote such inappropriate content.
One common theme is redemption. Since the hotel is about rehabilitating sinners, many fanfics explore how different characters seek redemption. Another is the power dynamics, like how Alastor has power over others in the hotel.
