Husk is a character that can be great to feature. His grumpy and alcoholic nature can provide some comedic relief in a fanfiction. Also, his backstory which is hinted at but not fully explored in the original material can be a great area for a fanfiction writer to dig into. Niffty is also popular, with her obsessive - compulsive cleaning habits and her perky personality being fun to write around.
Alastor is also very popular. His radio - host persona and his rather mysterious and powerful nature draw a lot of attention. Fanfic writers like to explore his past, what made him the way he is, and his relationship with the other characters in the hotel.
Charlie is often a popular character in these fanfictions. Her positive attitude towards redemption can contrast with the exterminator's more black - and - white view of good and evil.
Dracula is definitely a popular character. He's the owner of the hotel and has a complex personality. Writers can explore his relationship with his daughter Mavis in different ways, or his past experiences with humans. Mavis is also a favorite. Her curiosity about the human world and her growing up in a monster - dominated environment provide a lot of story potential.
Angel Dust is another popular character. His flamboyant personality and complex backstory mean that his reactions in the fanfic can be both humorous and deeply emotional. Viewers are often drawn to his character arc and how he'll grow or change in response to different situations.
Alastor is also a favorite. His radio - host persona, his power, and his somewhat unpredictable and menacing nature make him a fascinating character. Fan fictions might explore his past, what made him the way he is, or his interactions with other characters. He could be the antagonist in some stories, trying to undermine Charlie's plans, or he could end up being an unexpected ally in certain situations.
Well, aside from the main trio of Charlie, Alastor, and Angel Dust, Husk is becoming a popular character to include. His grumpy and alcoholic nature can provide some comical relief in crossovers. Niffty is also a great addition. Her hyper - active and somewhat naive personality can be a contrast to more serious characters from other crossovers. And let's not forget Lucifer, who can bring a whole new level of power and mystery to the crossover fanfic.
The Invisible Man is another character that can be interesting to write about in a fanfic. His ability to be invisible can lead to all sorts of comical or mysterious plotlines. You could write about how he uses his invisibility for good or mischief in the hotel, or how the other characters try to deal with his invisible antics.
Angel Dust is another one. His flamboyant and troubled past makes him a character full of potential for fanfiction. He could be involved in various storylines, such as his attempts to truly reform or his relationships with other characters that might develop in unexpected ways in the fanfiction world.
There are also some of the background demons that are written about. For example, some fanfictions might focus on a minor demon who the reader befriends. This minor demon could introduce the reader to the underbelly of Hell society. Another character that might be written about is Lucifer. Although he's not a main character in the show yet, his overarching presence in Hell makes him an interesting addition to fanfiction. The reader could have a fateful encounter with him, perhaps getting involved in some sort of power play or learning some dark secrets from him.
Charlie would be a great character to pair with Adam. Charlie is all about redemption and Adam could either be a foil to her or be influenced by her positive attitude. Their interactions could be really interesting as they have different outlooks on the whole idea of sin and redemption in the Hazbin Hotel world.
