Perhaps a young wizard who idolizes Ron. This character could be from a small wizarding community that has heard of Ron's adventures. He joins Ron on his journey in the fanfic and provides some comic relief as he tries to imitate Ron's every move but often messes things up in a humorous way.
There could be a mysterious witch who helps Ron. She might have some unique powers or knowledge about the Deathly Hallows that she shares with Ron. For example, she could be an outcast from a wizarding family who has been secretly studying the Hallows for years.
Another plot could involve Ron's relationship with his family during the events of the Deathly Hallows in the fanfic. His family has always been important to him, and perhaps in this story, he has to make a difficult choice that could impact his family's safety. He might have to decide between following Harry on a dangerous mission or staying back to protect his family, which could lead to some really emotional and tense moments.
Obviously, the children of the main characters from the original series could be great main characters. For instance, James Sirius Potter, Albus Severus Potter, or Lily Luna Potter. They would have their own adventures, perhaps trying to live up to the legacies of their parents while also forging their own identities in the wizarding world.
A new character could be an ancient wizard who has been in hiding for centuries. He could have knowledge about the Deathly Hallows that even Dumbledore didn't know. This character could appear to Harry and his friends and offer them guidance or a powerful magical artifact that helps them on their journey.
Harry Potter is the most important. He is the one who has to defeat Voldemort. Ron Weasley and Hermione Granger are also crucial as they help Harry throughout his journey. Voldemort himself is a major character. Albus Dumbledore also has an important influence even though he is dead, through his past actions and the knowledge he left behind.
In my opinion, Snape is often a very interesting character in Deathly Hallows fanfiction. His complex past and his true loyalties are always fascinating to explore further. There are many fanfictions that dig deeper into his relationship with Lily and how that influenced his actions throughout the series.
In some fanfictions, Ron's character might develop more confidence. For example, he could become more assertive in his relationship with Hermione and in battles. Hermione, on the other hand, may become more understanding of Ron's insecurities. They both grow closer and learn to rely on each other more.
In 'Deathly Hallows' fanfics, you can often find a wide range of characters from the original 'Harry Potter' series being read about. This includes the main trio, Harry, Ron, and Hermione. They are usually central to the fan - created stories, just as they were in the original books. Their relationships and adventures continue to be explored in different and creative ways by fanfic authors.
Harry Potter is without a doubt one of the most important characters. He is the central figure in the fight against Voldemort. Hermione Granger is also crucial. Her intelligence and knowledge of magic are always helping Harry and Ron out of difficult situations. And Ron Weasley, with his loyalty and sense of humor, is an important part of the trio.
Some characters might be skeptical at first. For example, Hermione would probably question the new interpretations based on her extensive research. She'd want to cross - reference with existing magical texts to see if there's any truth to it.
Neville himself is obviously a main character. Often, Harry, Ron, and Hermione also play important roles as they are part of the main story in the Deathly Hallows. Luna Lovegood might also be included as she is a friend of Neville's. And of course, the villains like Voldemort and his Death Eaters are usually there to create the conflict.
