Given that it's a fanfic based on Harry Potter, we expect Harry himself to be a main character. However, the beauty of fanfics is that the author can introduce their own unique characters. There could be a mysterious old wizard who has some secret knowledge that Harry needs to defeat the new threat. Or a Muggle - born wizard who has an extraordinary power that Harry has to learn to harness. Hermione and Ron, as Harry's long - time friends, would play important roles in the story, whether it's providing intellectual support or physical backup in battles.
In this 'harry potter the last wizard fanfic', Harry Potter is surely a central figure. But there could be new characters introduced as well. It could be a young wizard or witch who looks up to Harry and joins him on his new adventure. Hermione and Ron would likely be there to support Harry, and perhaps some old enemies turned allies or vice versa could also be part of the story.
Most likely Harry Potter would be a main character since his name is in the title. And probably his friends like Hermione and Ron would also be involved.
Often, you'll find a character who is a wizard or witch from Queens. They might be a young student going to Hogwarts, like a character named Jack who is excited and a bit nervous about leaving his Queens neighborhood for the magical school.
I'm not sure specifically as there could be many different fanfics with that title. It might be about Harry Potter in his final battle as a wizard, perhaps with new and unexpected challenges, allies, or enemies.
Harry Potter would surely be one of the main characters. Since it's about the last Horcrux, he's the one on the mission to destroy it. His friends, like Hermione and Ron, would likely also be main characters as they usually accompany Harry on his adventures.
Obviously, Harry Potter himself is often a main character. After all, the whole story revolves around him in the original series. Hermione Granger and Ron Weasley are also very common. They are Harry's closest friends, so it's natural for them to be in fanfics as well.
It could be about the last wizard in the Harry Potter world somehow getting involved with the Marvel universe. Maybe the wizard has to seek help from the Marvel heroes to save the wizarding world from a new and powerful dark force. Or perhaps the wizard brings a unique magic that the Marvel world has never seen before and causes a stir among the superheroes and villains alike.
Obviously, Harry Potter himself could be a main character. He could interact with the Royal Wizards and learn from them. Hermione and Ron could also be involved, with Hermione being especially interested in the knowledge of the Royal Wizards.
It's possible that some of the minor characters from the original Harry Potter series could take on more prominent roles. For example, Neville Longbottom could be a key character. He has shown great courage in the series, and in this fanfiction, he might be one of the few who can stand up to the black wizard. Also, Professor Snape's backstory and his relationship with the black wizard could be further explored, making him an important part of the story as well.
Obviously, Harry Potter would be one of the main characters. He's the central figure in the fight against Voldemort in the original series, so he'd likely be leading the last stand in the fanfiction as well. Ron and Hermione would also be main characters, as they are Harry's closest friends and allies.
The demi - wizard themselves is of course a main character. They usually have some sort of special backstory that sets them apart. Then there are often appearances by the well - known characters from the original Harry Potter series like Harry, Hermione, and Ron. They might be friends or mentors to the demi - wizard.
I don't know for sure as I haven't read this particular fanfic. But it could have the main character be an original creation with the 'lionheart' trait, or it might center around a well - known Harry Potter character like Harry himself with some new 'lionheart' - inspired story arc.
