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.
Well, Harry Potter is the main focus, of course. The Dursleys are essential as the abusers. Sirius Black could also be involved. He might be a figure who wants to rescue Harry from the Dursleys once he finds out about the situation. Snape could also play a role. Maybe he has some mixed feelings about Harry's situation, given his complex relationship with Harry's father. And Hagrid might be there too, as someone who cares for Harry deeply from the start.
Another character could be Neville Longbottom. In some fanfictions, Neville is neglected by his family not just because they think he's not as magically talented as they hoped, but they actively try to suppress his magic. This can lead to Neville having a more difficult time at Hogwarts initially as he has to overcome both the lack of support from his family and his own self - doubt.
His friends, like Ron and Hermione, are very likely to support him. They've always been there for him in the original story, and in this fanfiction scenario, they would be even more important in his life. Hagrid could also be a great source of support. He has a big heart and has always cared about Harry.
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.
Obviously, Harry himself is the central character. Then there could be his friends like Hermione and Ron. Hermione might help Harry manage his fortune in a smart way, like investing in magical books or rare potion ingredients. Ron could be the one who gives Harry more down - to - earth advice on how not to let the fortune change him.
Obviously, Harry Potter himself is the central figure. His friends like Ron and Hermione would also be involved. They would support Harry in his revenge plans, with Ron providing his loyalty and Hermione using her intelligence to strategize. Ginny Weasley might also be part of it, as she is Harry's love interest and a strong - willed witch in her own right.
Neville Longbottom could be a key character. He might take on a bigger role in Hogwarts in Harry's absence and also be in touch with Harry, providing support from the school. Ginny Weasley would also be involved as she has a close relationship with Harry. Additionally, some of the Hogwarts professors like Professor McGonagall could play important parts, either trying to bring Harry back or helping him in his mission outside the school.
Hermione would probably be involved. She's always by Harry's side, and she might be researching ways to help Harry tame the basilisk. Maybe she finds some useful spells or information in the library that gives Harry an edge.
Obviously, Harry Potter himself would be the central character. He's the one getting the tattoos after all.
