Hermione Granger would also be a great main character. Her intelligence and knowledge of magic would be invaluable to the group. She could use her research skills to figure out threats and come up with solutions. Another option could be Neville Longbottom. He has shown great courage and growth throughout the series. As a Hogwarts Guardian, he could bring his unique perspective and skills, especially his knowledge of Herbology which could come in handy in various situations, like dealing with magical plants that are part of a threat.
Harry Potter himself could be one of the main characters. He has a natural inclination towards heroism and protecting others, so he would fit well as a Hogwarts Guardian.
New characters could also be the main characters in this fanfiction. For example, a transfer student from a far - off magical school who has unique magical abilities. This character could bring in new ideas and techniques that the Hogwarts students are not familiar with. Or perhaps a student who has been overlooked in the regular Hogwarts hierarchy but has a hidden power or talent that makes them a key member of the Hogwarts Guardians. They could discover their power during a time of crisis and rise to the occasion, becoming a central figure in the story.
Hermione Granger could also be a main character. Her intelligence and knowledge of magic could play a crucial role in the story, especially when it comes to understanding the motives and powers of the Guardians of Power. And Ron Weasley might be there too, providing his loyalty and his own brand of magic skills.
Hermione would surely be a main character. She could be a fellow teacher, perhaps teaching Transfiguration or History of Magic. She would be the one Harry goes to for advice on teaching methods or when he has a difficult student. Another character could be Ron. He might visit Harry at Hogwarts and end up getting involved in some of the school's mysteries or helping Harry with a particularly difficult Quidditch - loving student.
Luna Lovegood could be a main focus. Her unique perspective on magic could be used to discover new magical phenomena that emerged after the battle. She might also be helping the other students deal with their post - battle stress, using her calm and dreamy nature to soothe them.
Draco Malfoy might be an interesting main character in this fanfiction. He could be in the Host Club as a way to redeem himself or to show a different side of his personality. Luna Lovegood would also be a great choice. Her unique perspective and dreamy nature could make the club more interesting and she could offer services like sharing her strange but fascinating knowledge about magical creatures.
It could also include some new characters created specifically for the fanfiction. Maybe a young wizard or witch from a minor house who plays a crucial role in uniting Hogwarts. They could have some special abilities or a unique backstory that helps in bringing the students together.
The heir themselves would be a main character, of course. And Harry Potter might still play a role, either as a friend or a rival to the heir. Dumbledore could also be a major character, guiding or observing the heir's journey.
Other main characters could include the ward's new friends at Hogwarts. They could be from different houses and have different personalities. Together, they form a group that helps the ward through various adventures, whether it's exploring the Forbidden Forest or uncovering secrets within the castle walls.
Most likely, the Hogwarts Four would consist of Harry Potter, who is known for his courage and his connection to Voldemort. Hermione Granger, with her vast knowledge of magic and quick thinking. Ron Weasley, who brings loyalty and a sense of humor to the group. And it could be Luna Lovegood as the fourth member. Luna has her own unique perspective on the wizarding world and could add a different flavor to their adventures.
Obviously, Harry Potter is the main character. He is the one taking on the role of the guardian. Hermione and Ron usually play important supporting roles as well. They help Harry in his mission to protect Hogwarts with their knowledge and skills.
Hermione Granger would likely be a main character. She could use her vast knowledge to help Harry in his efforts to fix Hogwarts, whether it's researching ancient spells for repairs or coming up with new educational strategies.
