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. He's the one getting the tattoos after all.
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 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.
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 and Severus Snape are the main characters. Harry is the one who is forced into this situation, and Snape is the one he has to please. But other characters like Hermione and Ron could also be involved. They might try to help Harry out of this difficult situation or be affected by the consequences of Harry's actions to please Snape.
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.
Obviously, Harry Potter himself. Hermione would probably be by his side, helping him research about his claim to lordship, using her vast knowledge from the library. Ron might also be there, providing moral support and his unique sense of humor in difficult situations.
Harry Potter himself is obviously a central character as the focus of the so - called 'harem'. Hermione Granger could be one of the likely characters involved. She is Harry's close friend in the original series and her intelligence and magical abilities would make her a strong contender in any relationship - based competition. Ginny Weasley is also a likely character, as she has a romantic relationship with Harry in the official story. Luna Lovegood might be included too, with her unique personality and magical insights.
Snape is a likely candidate. In the original series, his loyalties were always a bit of a mystery at first. In fanfiction, he could be further explored in terms of false betrayals or real ones. Another one could be Draco Malfoy. He was on the verge of becoming a full - blown Death Eater in the original, so in fanfiction, he could either truly betray his Hogwarts classmates or be wrongly accused of betrayal.
