Hermione is a great character to focus on. If reborn in the Harry Potter world, one could explore how she would be different if she had some extra knowledge or skills from her past life. Maybe she could be even more brilliant in magic and solve problems faster, or she could use her modern - day knowledge to make changes in the wizarding world like introducing new study methods.
Neville Longbottom is also interesting. If reborn, he could have more confidence from the start. He might remember all the times he was brave in the original story and build on that. He could be a key figure in fighting the Dark Arts much earlier and even become a leader among the students, showing a different side of Gryffindor courage.
Hermione Granger is always a popular choice. You can explore her further adventures in the wizarding world, like her research into new spells or her efforts to improve the lives of house - elves. Another is Draco Malfoy. There's a lot of potential to show his redemption arc in more depth or his post - Hogwarts life trying to make amends for his past actions. And of course, Harry Potter himself. You could write about his life as an adult, perhaps as a teacher at Hogwarts or his continued battles against the remnants of dark magic.
Hermione would be a great character. Her intelligence and strong sense of right and wrong would make her interactions with magical oaths very interesting. She could be the one to discover an ancient oath that has been forgotten and figure out how it relates to the current situation at Hogwarts.
The Weasley twins are always fun to write about. Their pranks could be taken to a whole new level in fanfiction. For instance, they could create a prank that accidentally affects the entire academy, like a spell that makes everyone's robes change colors every time they sneeze. And then they have to find a way to reverse it before they get into too much trouble.
Obviously, Harry himself is a central character. But there are also others. Hermione is often a key figure. In some fanfictions, she might be the one to first discover Harry's reborn state and help him adjust. Ron can also be important, as he provides the comical relief and loyalty that he did in the original series.
Definitely Ginny Weasley. She has her own growth story, and in fanfiction, it can be elaborated. She goes from being Harry's love interest to a strong, independent witch. Seamus Finnigan could also be a focus. He has a bit of a fiery personality, and fanfiction can show how he matures. And Fred and George Weasley. Their pranks and how they grow into more responsible but still fun - loving wizards can be great to write about.
Seamus Finnigan could be a great focus. He's often seen as just a side character, but in fanfiction, he could have his own moment. Maybe he discovers a new spell related to the Triwizard Tournament tasks that no one else knows about. He could use this spell to either help Harry or get himself into trouble while trying to prove himself.
Harry Potter himself could be a central character. His courage and ability to face dark forces could be put to the test in the Twilight universe. Maybe he has to deal with a vampire coven that has some dark intentions similar to Voldemort.
Harry Potter himself is often a popular reborn character. Writers like to explore what would happen if he had a second chance at life and could change things. It allows for a lot of creative interpretations of his character growth and how he would handle the challenges differently.
Harry Potter himself is a likely candidate. He has endured so much throughout his life, from the death of his parents to the constant battles against Voldemort. Fanfiction could explore his post - war trauma and how he tries to lead a normal life.
Definitely Snape. His complex character with his love for Lily and his role as a double agent has so much potential for exploration through memories. Harry himself is also interesting as his memories can uncover more about his family and his own growth. And Dumbledore, his past is full of mystery and his memories could reveal many secrets about his actions and motives.
