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 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.
The official website of Hazbin Hotel might offer the comic for reading. Additionally, some online bookstores that specialize in comics could have it. Just do a search and see what comes up, but be cautious of unauthorized or pirated copies.
