Harry Potter is the main character for sure. In addition, Dumbledore or other Hogwarts professors could make appearances. They might come to check on Harry or give him advice regarding his new life in Potter Manor. There could also be some family members from the Potter family tree, who were thought to be long - gone but now reappear in the form of memories or spirits in the manor.
There could also be some original characters created for the fanfiction. For instance, an old caretaker of the manor who knows some secrets about the trunk. Or perhaps a long - lost relative of the Potter family who shows up because of something related to the trunk. These new characters could add new dynamics and plot twists to the story.
In this fanfiction, it might be about Harry Potter's new life in Potter Manor. It could include his exploration of the manor, perhaps finding secrets within its walls. He may also have new relationships or experiences that are unique to this setting.
You could have a new generation of witches and wizards as the main characters. For example, the children of the original trio. They might be visiting the manor for the first time and discover something that their parents had missed. There could also be a misfit wizard who finds a sense of belonging at the manor, and his story could be the focus.
Perhaps a long - lost relative of the Potter family who feels they were unjustly excluded from inheriting the manor. This relative could be jealous of Harry's status and the wealth associated with the manor. They might use dark magic to try and claim what they think is rightfully theirs, leading to a battle of magic and loyalty within the Potter family and among Harry's friends.
Hermione could be one. She might follow Harry to the island to help him out. Another could be Ron, his loyal friend. Or it could be some new characters created specifically for this fanfiction, like a wise old wizard who has been living on the island for centuries.
There could be an old French wizard named Alphonse. He might be a mentor to Harry, passing on his knowledge of ancient French magic. Also, a young French witch named Celeste could be a main character. She and Harry could develop a friendship or more, and she could be part of Harry's new life in France, like helping him understand the French magical education system which is different from Hogwarts.
Hermione could be one. She might follow Harry to Australia to continue their adventures together. She could be interested in studying the different magical plants in Australia and how they can be used in potions.
The main trio - Harry, Ron, and Hermione - are very common. They are the protagonists of the original story and their presence in Malfoy Manor fanfiction can drive the plot forward. Draco Malfoy is an obvious choice as well, as it is his home. Additionally, Lucius Malfoy could be a prominent character. His role as a Death Eater and a father figure in the Malfoy family can add depth to the story. Some fanfictions might also include Luna Lovegood. Her unique perspective on magic could be useful when dealing with the strange and often dark magic associated with the Malfoy Manor.
Well, in fanfiction, Neville Longbottom could be one of the visitors. He and Harry could exchange gardening tips as they explore the manor's gardens. Additionally, Dumbledore's portrait might be magically transported to Potter Manor, and he could offer his wisdom and guidance to Harry as he lives in the manor. And of course, Hagrid might come with some magical creatures to show Harry, adding more excitement to the manor.
Obviously, Harry Potter is one of the main characters. He's the central figure around which the story revolves. And then there would be the giants. Maybe a particular giant who takes Harry in or becomes his mentor or adversary.
