There could be a love interest for Harry who is attracted to his long hair. This character could be someone new, perhaps a transfer student from another wizarding school. She could encourage Harry to keep growing his hair and help him style it in different ways. And Dumbledore, as always, could be a significant character. He might see Harry's hair - growing as a sign of his maturing in a different way and give him some wise words about self - expression and the power of change.
Obviously, Harry would be the main character. But Hermione could also play an important role. She might be initially against Harry growing his hair out, thinking it's unhygienic or against school rules, but then she comes around and helps him take care of it with some magic hair products she invents.
The main characters are Harry and Tom. Harry, the boy who lived, and Tom, who could be a complex character in this fanfiction. He might not be the evil Voldemort we know from the original story. Instead, he could be a young wizard with potential for good or bad, and Harry's influence on him is a major part of the story.
Well, clearly Harry and Hermione are the main characters. Harry, the boy who lived, with his courage and natural talent for facing dark magic. And Hermione, the brilliant witch, with her vast knowledge of magic and her logical thinking.
Hermione could be a main supporting character. She might help Harry and Daphne with their studies and magical research. Ron could also be there, providing some comical relief and loyalty to Harry.
Perhaps in this fanfiction, Harry grows his hair out because he's on a long journey away from the wizarding world. He doesn't have access to hair - cutting magic or tools, and as his hair grows, it becomes a symbol of his growth and the challenges he's facing. He might also discover new magical abilities related to his long hair, like using it as a sensory extension to detect danger.
The main characters would be Harry and Lily. But it's possible that we could also see some appearances from the Marauders in flashbacks. Since Lily was friends with them, they could be part of the backstory. Also, Dumbledore might be involved in some way, perhaps as a guiding figure from afar, still looking out for Harry's well - being and the safety of the wizarding world.
Hermione could be a main character. She would be the one trying to figure out the magical theory behind Harry's cocoon - building and wing - growing. She might be researching in the library, looking for any mentions of similar phenomena in ancient magical texts.
Hermione could be another main character. Maybe she discovers what's happening to Harry and the author and tries to find a way to reverse it or at least understand it better. She could use her vast knowledge of magic to research the phenomenon.
Definitely Ginny. Since she's Harry's love interest in the original series, in the fanfiction about them growing up, she has a big role. She could be shown as a strong, independent witch who is equal to Harry in many ways. Draco Malfoy is also a character that features a lot. Sometimes, fanfiction explores his redemption arc further as he and Harry have to interact in the post - war wizarding world.
Obviously, Harry himself is the central character. His friends like Ron and Hermione usually appear as well. The professors such as Dumbledore, McGonagall, and Snape are also common characters. They play important roles in guiding Harry as he grows up at Hogwarts.
Obviously, Harry and James are the main characters. But there could also be Lily, Harry's mother, who would play an important role in his upbringing. Sirius Black might also be around a lot, as he was James's best friend.
