Harry Potter himself could be the main character. Imagine if he discovers that he has some paladin - like traits due to the prophecy. He would then have to balance his existing wizarding abilities with these new aspects of being a paladin, like having a stronger sense of moral obligation towards the entire wizarding community.
It could be a new character, perhaps a transfer student from a different magical school where paladin - like training is part of the curriculum. This character comes to Hogwarts with the knowledge of the paladin prophecy and believes that they are the one to fulfill it. They then interact with the existing characters in the Harry Potter series, teaching them about paladin values and working together to face the challenges ahead.
Well, it could be about a character in the Harry Potter universe who discovers they have a connection to the paladin prophecy. Maybe they start to show paladin - like abilities such as great courage and a sense of justice. This could lead them on a journey to fulfill the prophecy, facing many of the dark forces in the wizarding world along the way.
Perhaps an older student who has been overlooked in the past. She's not one of the popular kids but she has a strong sense of justice. When she witnesses something wrong happening to Fawkes, she steps in to protect him. This act of kindness makes her the center of a series of adventures involving Fawkes and the secrets he holds.
Well, obviously Harry is one of the main characters. He is the paladin at the center of the story.
It could be a new character, like a young Auror who has been assigned as an inspector. He would be fresh out of training and eager to prove himself at Hogwarts. He might be a bit naive at first but quickly learns the ropes and uncovers some interesting things about the school.
It could be a young witch who is just starting to explore her magical abilities outside of Hogwarts. She takes on a babysitting job to earn some extra money and ends up having all sorts of magical adventures with the kids she babysits.
A new character could be the main character. For instance, a Saiyan who has been transported to the Harry Potter universe. This character would have to navigate the strange new world of magic while also dealing with their own Saiyan instincts and powers.
It might also be a descendant of one of the well - known characters from the Harry Potter series. For example, a grandchild of Sirius Black who inherits his rebellious spirit and uses it to fight against the new dark forces as the 'darkslayer'.
A new student at Hogwarts could be the main character. They might be a bit of an outcast and find solace in the graveyard. There, they stumble upon a mystery that no one else has noticed before, and it becomes their mission to solve it. This would be a great way to introduce a fresh perspective to the Harry Potter fanfic world.
It could be a long - lost relative of Harry Potter. Maybe a cousin who was hidden away for some reason and now discovers their magical heritage. They could have a different personality from Harry, like being more shy and studious but still having a great sense of justice.
Obviously, Harry Potter himself could be the main character. Given his adventurous nature, he would be a great fit to incorporate parkour into his already impressive list of skills. He could use parkour to explore new areas of Hogwarts or to escape from dangerous situations.
