Harry is the central figure for sure. Besides Ron and Hermione, Dumbledore might also be in the story. Dumbledore, with his vast knowledge, could be the one to offer some solutions or at least some guidance to Harry about his animagus state in heat. Also, other characters from the wizarding world who are familiar with animagi might make an appearance to either help or hinder Harry's situation.
Obviously, Harry himself would be the main character. His friends like Ron and Hermione are also likely to be involved. They would probably try to support Harry or figure out what's going on with him.
The main character is Harry. In addition to his close friends, there could be some characters from the magical creatures' side. For instance, if there are other animagi in the story, they could play important roles. There might also be some professors at Hogwarts who notice Harry's strange behavior and get involved. Lupin, as an expert in all things related to werewolves (and animagi have some similarities in terms of transformation), could be another character that gets pulled into the story to help Harry understand and deal with his situation.
Harry Potter himself is often a main character. Since he has a connection to stags through his Patronus, it's common for fanfiction to explore his potential as a stag animagus. Another is James Potter, Harry's father, who was an animagus and took the form of a stag.
The main characters would be Naruto and Akamaru. But there could also be other characters involved like Kiba, Akamaru's owner. Kiba might be worried about Akamaru and work together with Naruto to figure out what's wrong and how to fix it. Also, characters like Shino or Hinata could make an appearance, maybe they offer some help or just witness the events that unfold.
Harry Potter himself is often involved. Fans like to write about his potential Animagus training, imagining what kind of animal he might turn into, perhaps a stag like his father's Patronus. Hermione Granger is also a common character. Given her thirst for knowledge and magical ability, she could be exploring Animagus training. Ron Weasley might be included too, and his transformation could be into an animal that reflects his loyalty and sometimes clumsy nature, like a dog.
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.
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.
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.
Obviously, Harry himself is the central character. Then, there could be characters like Dumbledore who might play a role in guiding Harry about his new heritage. Hermione would also likely be involved, using her knowledge to help Harry understand the Pendragon history.
