Most likely Harry Potter himself as he is in the title. And probably his friends like Hermione and Ron might also be important characters, still supporting him in this new 'king of magic' scenario.
Obviously, Harry Potter is one of the main characters. But there could also be new characters created specifically for the fanfiction. For example, a powerful witch or wizard who becomes Harry's ally or rival. Hermione and Ron might also play important roles, perhaps with new aspects to their characters as they interact with Harry in his new 'king of magic' role.
Obviously, Harry Potter is one of the main characters. Since it's about him being a king in some way. Hermione Granger and Ron Weasley are likely to be main characters as well, as they are Harry's closest friends and would play important roles in his new 'king' - like journey. There could also be other characters like Dumbledore, either in spirit or through memories, guiding Harry in his new role.
I'm not entirely sure as it's a fanfic, but it could feature Harry Potter himself still as a central figure. Maybe he has new relationships with characters who are also deeply in love with magic.
Not having read 'The Magic Weaver' a Harry Potter fanfic, we can only speculate. The main character is most likely the one referred to as the Magic Weaver. This character might be a self - taught wizard or a wizard with a unique heritage that gives them this special ability to weave magic. There could be other important characters like a mentor figure who helps the Magic Weaver understand and control their powers. Maybe there are some antagonists too, perhaps jealous wizards who see the Magic Weaver's abilities as a threat. And of course, there's a possibility of cameo appearances from the main Harry Potter characters to tie the story into the original universe.
Obviously, Harry Potter would be one of the main characters as it's about him being the rightful king. Hermione and Ron might also be important as they usually support Harry in his adventures and would likely be by his side in this new role as well.
In the 'Harry Potter Serpent King Fanfic', Harry Potter is bound to be a central figure. He might be the one who has to face the challenges posed by the Serpent King.

He could be a complex figure with his own motives and backstory that the fanfic will gradually reveal.
Well, Harry Potter is bound to be a central figure in this fanfic. The wolf king is another main character. It's possible that other characters from the original series could play important roles too. For instance, Dumbledore might offer some wisdom or guidance regarding the wolf king. Or perhaps some of the darker characters like Voldemort's followers could be interested in the power of the wolf king and try to get in Harry Potter's way as he deals with this new entity. Neville could also be a character in this fanfic, showing his growth and courage as he helps Harry Potter face the challenges related to the wolf king.
Most likely Harry Potter would be one of the main characters. Since it's a crossover with the Potter universe.
It's hard to say without reading it, but it could be Harry Potter himself as the story is related to his family. Maybe there's a new villain who is trying to steal the family magic.
Obviously, Harry Potter himself could be one of the main characters. He has a lot of untapped potential in terms of family magic that could be explored. For example, delving deeper into the magic he inherited from his parents.
