One idea could be that the characters from Hazbin Hotel end up in Paris where the Miraculous Ladybug story takes place. They could interact with Ladybug and Chat Noir, and maybe some of the chaotic energy from Hazbin Hotel causes trouble for the heroes as they try to keep the city safe. For example, Angel Dust might accidentally cause a distraction during an akuma attack.
Another option is a crossover with Gravity Falls. Dipper and Mabel could end up in Hell for some wild reason, like following a strange portal. They'd meet the Hazbin Hotel crew and chaos would ensue. Dipper would be all about trying to figure out the logic and secrets of this new place, while Mabel would probably befriend some of the more outlandish demons or sinners. Charlie would see the Pines twins as a chance to prove that redemption is possible even for those from other dimensions.
First, decide which other fandom you want to cross over with. Once you've made that choice, research both Hazbin Hotel and the other fandom. Know the characters, their personalities, and the rules of their respective worlds. For example, if you're crossing with a fantasy world, understand the magic system. Then, come up with a basic plot. It could be as simple as a character from the other fandom getting lost in Hell and ending up at the Hazbin Hotel. Start writing the introduction, introducing the situation and the character's initial reaction to this strange new place.
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.
It also keeps the interest alive during the wait for new official content. When there's a long gap between new episodes or developments in the official Hazbin Hotel story, these fanfictions give fans something to enjoy. They can explore new storylines and ideas that are inspired by the original but still have their own unique twists, like a fanfic where the characters react to a time - travel scenario.
One interesting concept could be crossovers with other popular animated shows. For example, a crossover with 'Steven Universe' might bring unique character interactions. The different power sets and personalities from both universes could create engaging storylines. Another concept could be a crossover with a classic fairy - tale world. The demons from Hazbin Hotel interacting with fairytale characters would be quite a sight, like the sinners trying to corrupt the pure - hearted fairytale folks or vice versa.
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.
The Doom Slayer and Charlie would be an interesting pair. Charlie is all about redemption and trying to make Hell a better place, while the Doom Slayer is focused on pure destruction of demons. Their meeting could lead to some great character development. Charlie might try to convince the Doom Slayer that not all demons are irredeemable, while the Doom Slayer could show Charlie the true horror that some demons are capable of.
One idea could be to write about Michael's backstory before arriving at Hazbin Hotel. Maybe he had a difficult life on Earth that led to his damnation. You could explore his relationships, like if he had a family or friends that he left behind.
