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.
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.
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.
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.
Danny and Dracula are often paired. Danny's youthful energy and ghost - related adventures contrast well with Dracula's old - world charm and leadership in the hotel. It makes for an interesting dynamic as they come from such different worlds yet have to find common ground.
Tyrone is a favorite as well. His laid - back yet reliable nature is appealing. He could be the one who keeps the group calm during a crisis in the fanfic, or he could be the one who discovers a new area of the backyard that leads to an exciting adventure.
Aphmau herself is obviously a very popular choice. Her journey and development are interesting to explore further in fanfics. Aaron is also a favorite among fans. His relationship with Aphmau and his own backstory provide a lot of material for fanfic writers.
Another one could be Luna, the wise old cat. She has a lot of knowledge about the Catswold's history and secrets. Writers can have her guide the younger cats or solve complex problems using her wisdom, which makes her a great character to feature.
Midoriya is extremely popular. His journey from being quirkless to a powerful hero - in - training is very inspiring, and there are many ways to explore his character further in fanfic. Bakugo is also a top choice. His complex personality, with his aggressive nature and underlying insecurities, offers a lot of material for writers. Todoroki is another popular one. His troubled family history and his dual - quirk ability make him a fascinating character to write about.
Kirari Momobami is also a fan - favorite. Given her position of power within the academy and her own complex personality, a fanfic could delve into her plans for the future of the school, her relationships with other powerful families, and how she might handle challenges to her authority in the form of gambling duels.
Filia is often a popular choice. Her unique situation of being a host to Samson gives a lot of room for interesting stories. There's also Parasoul, with her leadership role and complex family dynamics that can be explored in fanfic.
