Voldemort or some remnants of his dark followers could also be in the fanfiction. Their presence would create conflict and give Harry a reason to use his magic. And don't forget Dumbledore's spirit might appear to guide Harry, as he was such an important figure in Harry's life in the original series.
Obviously, Harry himself would be a central character. Hermione and Ron would most likely be in it too, as they are Harry's closest friends.
A centaur could also be the Guardian of Magic. Centaurs are known for their wisdom and connection to nature. They might see it as their duty to protect magic from being misused by humans. In the fanfiction, the centaur - guardian could use their knowledge of the stars and natural magic to combat the dark wizards.
Hermione could be a strong ally. She's smart and could help Harry research more about battle magic. Ron too, with his loyalty and courage, would be by Harry's side.
Obviously, Harry Potter and Severus Snape are the main characters. Harry, the young wizard with a heart of gold and a thirst for justice. And Severus, the complex and often misunderstood character with his deep knowledge of magic and his own hidden motives.
Obviously, Harry Potter is the central character. Since it's about him being blessed by magic. Then there's Hermione Granger and Ron Weasley, as they are his closest friends in the wizarding world and are likely to be involved in any story about Harry. Dumbledore is also often included as he plays a crucial role in guiding Harry in the original series, and his wisdom would be relevant if Harry has a new magical situation.
There could be new original characters created specifically for this fanfiction. They might be mentors or allies to Harry in his journey. For example, a powerful and mysterious wizard who helps Harry understand the true nature of his being chosen.
Hermione Granger might also be a main character. Given her intelligence and knowledge of magic, she could be helping Harry in his quest to break magic. She might be researching ancient spells or looking for loopholes in the magical laws. Ron Weasley could be there too, providing support and his own brand of humor and loyalty as Harry undertakes this dangerous mission.
The main character is Harry Potter. In addition, there could be a character who is Harry's long - lost brother or sister, also having special magical abilities. This character could play a significant role in helping Harry understand his new identity. There might also be a powerful wizard from a foreign land who comes to Hogwarts to study Harry and his powers. And, there could be a character within Hogwarts, perhaps a teacher or a student, who initially doubts Harry's new status but later becomes his most loyal supporter.
It's possible that some of the antagonists from the original series could have a different role in this fanfiction. For example, Draco Malfoy might start off as an adversary but then be forced to work with Harry due to the implications of Harry's blessed magic on the entire wizarding world. This could lead to a more complex and interesting character dynamic compared to the original story.
Well, Neville Longbottom can be quite popular in these fanfictions. He has shown great potential in the original series, and in wild magic fanfiction, he could be the one to unlock the secrets of wild magic. Luna Lovegood is another favorite. Her unique perspective on magic in the original books can be expanded upon in wild magic stories. She might be seen as having a natural understanding of the wild and unpredictable nature of this type of magic. And then there's Professor Snape. His complex character can be explored further in the context of wild magic, maybe he has a hidden past related to it.
Obviously, Harry Potter is one of the main characters. But there could also be new characters created specifically for the fanfiction. For example, a powerful witch or wizard who becomes Harry's ally or rival. Hermione and Ron might also play important roles, perhaps with new aspects to their characters as they interact with Harry in his new 'king of magic' role.
