Well, they could be into fanfics that expand on their family backgrounds. Since we know some bits about their families in the original books, a fanfic that dives deeper into their family legacies, how it influenced them, and how they interacted with their family members outside of Hogwarts could be something they'd like to read.
Yes, it's possible that some fans who are interested in the Mauraders might read Harry Potter fanfic. Since the Mauraders are an important part of the Harry Potter universe, many fanfictions explore their backstories, relationships, and adventures. Fanfic can provide different perspectives on the Mauraders that may not be fully explored in the original books.
Fanfiction that delved into the inner workings of Hogwarts during his tenure as a teacher might be of interest to Snape. He was deeply involved in the school, and stories that show his interactions with other teachers, his influence on the students (not just Harry), and his role in the overall Hogwarts community could be something he would want to read. Also, any fanfiction that tries to understand his dark past, his time as a Death Eater, and how he eventually turned against Voldemort would likely hold his attention.
Neville Longbottom could be one. Neville is a character who has grown a lot throughout the series. He has a love for magic and the wizarding world. Fanfics can provide new adventures and perspectives on the things he already loves. He would be interested in reading about how other fans imagine the world he lives in.
One reason could be their ambition. They might see fanfiction as a way to gain more knowledge about the wizarding world. Another reason is that they could be looking for stories that give Slytherin characters more depth or a better reputation.
Dracula might be interested in Gothic novels. Given his own nature as a vampire, stories filled with mystery, the supernatural, and elements of horror would likely appeal to him. Novels like 'The Castle of Otranto' which are considered early Gothic works could be among his favorites.
I think I'd be into a fanfic where Harry Styles goes on a magical adventure and discovers hidden talents.
He might be interested in the ones that explore different relationships between the characters. For example, stories that focus on the friendship between Harry and Hermione in a new light.
One character could be Hermione Granger. In many fanfics, she is often depicted as being interested in exploring different interpretations of the Harry Potter universe in fan - written stories. She has a great love for books and knowledge, so she would be curious about fanfictions that expand on the world she already knows.
Cry could potentially be interested in fanfiction that delves deep into the lore of the games he loves. This would include detailed character backstories and alternate universes within those game worlds. PewDiePie, on the other hand, might like fanfiction that parodies popular culture. It could be something that takes a well - known movie or TV show and twists it into a hilarious new story. Maybe a fanfiction that combines his own online persona with other famous characters in a comical way would also be of interest to him.
Fans of both the character Harry (whichever Harry it might be, could be from a well - known series) and the Riddler would be interested. People who like crossovers and unique combinations of different fictional elements would also find it appealing.
