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.
Perhaps he likes the fanfiction that delves into the backstories of the minor characters. There are so many interesting characters in the Harry Potter world like Luna Lovegood, and fanfictions that expand on their pasts can be really fascinating. Keith could be drawn to these types of stories as they add more depth to the overall wizarding world.
I think he could also be interested in ballet folklórico. The colorful costumes and the cultural stories behind it might intrigue him. Harry has always been open to different cultures and ideas, and this form of ballet, with its roots in different cultures, could be something he would explore. He might even incorporate some of the magic from his wizarding world into the performance of ballet folklórico, creating a unique and magical experience.
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.
Yes, he could be. If Keith is into Harry Potter fanfiction, there's a chance he might be a writer creating his own stories within the Harry Potter universe.
Fans of both Harry Potter and the concept of the Dragon Mother would likely be interested. People who like to see crossovers between different fictional universes might also be into it.
He might like adventure - based fanfiction. For example, ones where Harry and his friends go on a new, dangerous quest that wasn't in the original books. Maybe they explore a hidden part of Hogwarts or a far - away magical land.
He might sing wizarding world ballads that are part of Hogwarts' cultural heritage. These could be songs passed down through generations of witches and wizards.
He might be interested in ones that focus on his relationship with Toothless. For example, stories that explore new adventures they could go on together, or how their bond might change over time in different situations.
He could have a flying custom car. Given his wizarding abilities, it would be cool to imagine a car that can fly like a broomstick but with the added features of a Muggle car, like a radio or air conditioning.
Perhaps he uses the island as a secret training ground. He could practice advanced spells away from the prying eyes of Hogwarts faculty and students. Harry might also build his own magical fortress on the island for protection and privacy.
He might encounter magical ravens that can perform spells. These ravens could be guardians of certain magical places or objects. For example, there could be ravens protecting the entrance to a hidden chamber in Hogwarts.
