It could be a new student who has just received their Hogwarts letter. They are excited about the flight camp as they have always dreamed of flying. This character could bring a fresh perspective to the magical world of flying at Hogwarts.
A character from another wizarding school could be the main character. For example, a student from Beauxbatons. They come to the Harry Potter flight camp with different flying techniques and a different attitude towards magic. Their presence could cause some friendly rivalries and cultural exchanges among the students at the camp.
Well, it could be about a young wizard who is not very confident in flying but is forced to attend the flight camp. There, he meets a group of misfits, and together they discover a secret about the flying brooms that could change the way they view Quidditch forever.
There could be a fanfiction where a new character in the Flight Camp has a connection to the Dursleys. This character could be a long - lost relative or someone who knew the Dursleys in the past. This connection then leads to a series of events that involve Harry and his relationship with the Dursleys and his experiences at the Flight Camp.
In a fanfiction, perhaps the Flight Camp is in trouble and they need the help of someone from the Muggle world, which is where the Dursleys come in. The Dursleys initially resist but then Harry shows them how important it is. And along the way, they learn more about Harry's world and become more accepting. This could be a story of growth for the Dursleys.
How about Neville Longbottom? He could be the main character in a fanfiction set in the Chamber. Neville, who has always been underestimated, could show his true courage and strength. He might discover a hidden ability that helps him face the challenges in the Chamber, perhaps something related to his connection with plants, which could play a crucial role in defeating the Basilisk or whatever new threat is in the Chamber.
A lesser - known character like Ernie Macmillan from Hufflepuff could be the main character. As a prefect, he could bring out the unique qualities of Hufflepuff house. He might have to deal with issues like other houses underestimating Hufflepuff students. His story could focus on how he promotes the values of hard work, loyalty, and fairness within the house and the school as a whole.
Hermione could be a great main character. She's curious and intelligent, so she would be really interested in exploring the secrets of the diary. She could use her vast knowledge of magic to try and figure out how the diary works and what secrets it holds.
Harry Potter himself could be the main character as a revenant. Maybe he has some unresolved issues from his past, like his relationship with his parents. His revenant form could be on a journey to fully understand their sacrifice and his own place in the wizarding world's history.
It could be a younger sibling of one of the main characters in the original series. For example, Ginny's little sister who has big shoes to fill but also a great passion for Quidditch.
Hermione could be a great main character in an elementalist fanfiction. Her intelligence and thirst for knowledge would make her eager to learn about and master elemental magic. She could be the one to discover a long - lost elemental spell book and start exploring the powers.
It could be a new student at Hogwarts who has a natural talent for dealing with beasts. This student could be from a family that has always had an affinity for magical creatures but has kept it a secret until now.
