Harry Potter is the central figure for sure. But Dumbledore's spirit or memories could also be involved. Dumbledore has always been a guiding figure for Harry, and in a story about Harry welcoming death, Dumbledore's teachings and wisdom might come into play. Additionally, Voldemort could be there too. His presence and the threat he poses could be a major factor in Harry's decision to welcome death, perhaps as a way to finally defeat him.
The main character is Harry Potter as it is in the title. However, Neville Longbottom could also be involved. Neville has shown great courage and growth throughout the series. In this fanfiction, he might be the one who tries to understand Harry's decision and maybe even take on Harry's mantle if he goes through with welcoming death. And of course, Ginny Weasley, being Harry's love interest, would have a significant role. She would be deeply affected by Harry's attitude towards death and might try to change his mind or come to terms with it herself.
Obviously, Harry Potter himself would be a main character since the title revolves around him. Hermione and Ron are also very likely to be involved. They are Harry's closest friends throughout the series and would surely play a part in a story where Harry is welcoming death. They might try to stop him or support him depending on the direction of the fanfiction.
Harry himself is very likely to be involved. Given his many encounters with death, from facing Voldemort to losing loved ones, he has a deep connection to the concept. He would be exploring the aspect of death perhaps to gain more power to protect his friends and the wizarding world.
The villains in the Harry Potter series, such as Voldemort or his Death Eaters, could also play important roles. Harry's anger might be directly related to their actions. For instance, if Voldemort were to target someone Harry cares about again, it could be the trigger for his extreme anger. His interactions with these villains in the fanfiction would be full of tension and high - stakes confrontations.
Obviously, Harry Potter himself would be the central character. He's the one getting the tattoos after all.
Harry Potter is the main focus, of course. But in addition to Hermione and Ron, we might also see characters like Hagrid. Hagrid has a soft spot for Harry and would surely be concerned about his situation. Ginny Weasley could also play a role, perhaps being more nurturing towards baby Harry. And then there are the villains. Voldemort or his Death Eaters might be involved, either trying to take advantage of Harry's weakened state or being thwarted by the efforts of Harry's friends to protect him.
Obviously, Harry Potter himself would be the central character as the title implies. Hermione and Ron would most likely be involved as well, since they are Harry's closest friends. They would probably be the ones trying to figure out what's wrong with Harry and how to fix him. Dumbledore could also play a big role, as he often has the wisdom and power to deal with strange situations.
Obviously, Harry Potter himself. He's the one who has become the Master of Death. Hermione and Ron would also be important. They'd be there to support Harry, and also to question his new power and the moral implications. Dumbledore might also play a role, perhaps as a guide from beyond the grave, since he was always so interested in the Deathly Hallows and what it means to be the Master of Death.
Obviously, Harry Potter would be the main character since it's in his name. He is the one who befriends Death. Hermione Granger and Ron Weasley are also likely to be important characters. They are Harry's closest friends and would be involved in the story, either trying to understand Harry's new friendship with Death or being affected by it in some way. For example, they might be worried about Harry's sanity or the implications of befriending such an otherworldly being.
Obviously, Harry Potter himself is always a main character. He is the one most directly associated with the concept of death in the original series, what with his parents' death and his multiple near - death experiences.
There could also be characters like Dumbledore, even if in spirit or through memories. His wisdom might have influenced Harry's understanding of life debts, and his past actions could be related to debts that Harry is now calling in. And then there are the characters who owe Harry their lives. This could include Neville, who Harry has saved on multiple occasions, and their relationship could be further explored in the context of the life debt.
Obviously, Harry Potter himself is the central character as the one being abused and neglected. The Dursleys are also key characters as they are the ones who abuse and neglect him in the original story. Hermione and Ron might also be involved as they could be the ones to discover Harry's situation and try to help him. Dumbledore could also be a part of it, perhaps as someone who failed to notice or prevent Harry's abuse initially.
