Dumbledore could be another character involved. As Harry's mentor, he might try to guide Harry through his anger, or his actions could be a source of Harry's frustration. Dumbledore's wisdom and secrecy in the original series often left Harry feeling confused and sometimes angry, so this dynamic could be further explored in the fanfiction.
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.
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.
In addition to the above, other characters from the wizarding world could be involved. For example, the Order of the Phoenix members. They might be suspicious of Harry at first but then come to his aid. And there could be some new characters created specifically for the fanfiction. Maybe a mysterious old wizard who has knowledge about the Dark Mark that no one else does and helps Harry on his journey to rid himself of it or at least understand it better.
Hermione is a must. Her intelligence and extensive knowledge of magic and Hogwarts rules would be invaluable. Ron would be involved too. He's Harry's close friend and has a bit of a mischievous streak himself. Fred and George Weasley are very likely to be part of it. They are known for their love of pranks and their dislike of authority figures like Umbridge. Luna Lovegood could also be included. She has a unique perspective and might come up with some really out - of - the - box ideas for Harry's revenge on Umbridge. Plus, her presence would add an interesting and somewhat dreamy element to the whole revenge plot.
Obviously, Harry Potter and the Mad Hatter. But there could also be other characters from the Harry Potter universe making appearances. Maybe Dumbledore would come to check on Harry and be completely bewildered by the Mad Hatter's ways. And of course, there could be some of the Wonderland characters popping up too, like the March Hare or the Cheshire Cat, adding more chaos to Harry's life.
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 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.
Kakashi could also be an important character. He has a lot of experience and wisdom. When Naruto gets high, Kakashi might be the one to guide Naruto through this strange state, using his own past experiences and knowledge of different ninja techniques. And then there's Jiraiya. Given his relationship with Naruto, he would surely be involved, perhaps trying to use his own unique jutsu to help Naruto come back to normal.
Hinata would also play a major role. Since she has deep feelings for Naruto, she would be devastated by his amnesia. She might try to use their shared memories, like the time she confessed her love to him during the Pain attack, to jog his memory. And the Akatsuki members could also be involved in some cases. If Naruto's amnesia was caused by their actions, they might be the antagonists in the fanfiction, or they could also be trying to use his amnesia for their own purposes.
