Dumbledore could play a significant role. Even though he is dead in the original series, in this fanfiction, his spirit or some form of his wisdom could be involved. He might have known about the possibility of Harry befriending Death all along and left behind clues or guidance for Harry. Luna Lovegood could also be a main character. Her unique perspective on the magical world could make her more open to the idea of Harry's friendship with Death, and she could offer her own insights and help Harry navigate this strange new relationship.
There could be new characters introduced specifically for this fanfiction. For example, an old wizard who has had past experiences with Death and can offer advice to Harry. This character could have a mysterious backstory, perhaps having made a deal with Death in the past. Another new character could be a young witch or wizard who is also drawn to the concept of Death and befriends Harry because of his connection. They could form a sort of club or group dedicated to understanding the mysteries of Death in the wizarding world.
Hermione could be a main character. She might be the one who first notices the strange changes in Harry after he becomes friends with Death. She could try to research about this unusual friendship in the library, using her vast knowledge to understand the implications. Ron could also be important. He might be initially skeptical about Harry's new 'friend' but then come to accept it as he sees the positive effects it has on Harry and the help it provides in their fight against dark forces.
Besides Harry, death is the central character in this concept. But there could be other magical creatures or beings involved. Maybe thestrals, since they are associated with death in the original Harry Potter lore. They could play a role in facilitating the friendship between Harry and death. And of course, Harry's other friends from Hogwarts, like Neville and Ginny, could also be part of the story, either being curious about or affected by Harry's friendship with death.
Dumbledore would still be an important character. His interactions with Harry, who is raised by Lady Death, would be filled with a lot of mystery and caution. He might try to understand the implications of Harry's upbringing and how it affects the balance of power in the wizarding world. Hermione and Ron could also be main characters. Their friendship with Harry might be strained at first as they try to understand his new and rather dark - influenced personality, but they would still be important in Harry's life as they support him in different ways and help him navigate the challenges he faces at Hogwarts.
Death, of course, would be a major character as it's training Harry. Maybe Dumbledore could also play an important role. He might be the one who initially guides Harry to this encounter with Death or acts as a moral compass during the training.
Hermione is often involved. Since she's Harry's best friend, she might be the one trying to prevent his death in some fanfictions. Or she could be the one who has to carry on his legacy after he dies.
Well, I think Ginny could be a main character. As Harry's love interest, she would be deeply worried about Harry's strange connection with death. She might try to pull him back from this dangerous relationship. And then there could be Voldemort. Even though he is dead, his influence on Harry's life was huge. In this fanfiction, his shadow or essence could still linger, and Harry could discuss with Death how Voldemort's actions and his own role in defeating him have shaped his view of death.
Harry Potter would definitely be one of the main characters, since it's about him being the 'child of death'. There might also be his friends like Hermione and Ron, as they are often involved in his adventures.
Obviously, Harry Potter is the main character as it's about him being the Son of Death. Hermione and Ron are likely to still be important characters, as they are his closest friends.
In this fanfiction, Harry Potter is probably the central figure as it seems related to his new identity as the Heir of Death. However, other characters like Dumbledore could play significant roles. Dumbledore might be guiding Harry through this new discovery, or perhaps he's been hiding some secrets about the Heir of Death all along. Additionally, we may see characters from the dark side, like Voldemort or his followers, being involved in the story, either trying to stop the heir or use their power for evil.
The main characters would surely include Harry Potter. He is the one making the trade with Death. Death is also a main character as it is the entity with which the trade is being made. Additionally, Dumbledore could potentially play a role, either as a guiding spirit from beyond (if he has passed away in the context of this fanfiction) or as someone whose teachings influence Harry's decision to make the trade.
The main character is Harry Potter. In this fanfiction, Death is not just an abstract concept but an important entity. It's likely that other characters like Ginny Weasley could also be involved. Ginny might be worried about Harry's new relationship with Death. And characters like Luna Lovegood could offer their unique perspectives on this strange occurrence, adding depth to the story.
