Another typical character could be Luna Lovegood. Her unique perspective on magic and the wizarding world would be an interesting addition to the harem. She could offer insights and magical solutions that are outside the norm, which would be very useful in a harem situation where they might be facing various challenges, both magical and related to the harem laws.
Harry Potter is obviously a central character. Then there could be female characters like Hermione who might take on yandere traits in the fanfiction. Also, characters like Ginny Weasley could be part of the harem with yandere - like behaviors towards Harry.
In these fanfictions, the main character with godlike powers is central. Alongside him, the harem often consists of strong - willed female characters from the original series. For instance, Luna Lovegood could be in the harem, with her unique perspective on magic. And there may be a character who is a half - blood or a pure - blood witch from a minor wizarding family, added to bring in new story elements related to the harem and the overall wizarding world.
Harry Potter himself is often a central character. Given his status as the hero of the original series, many fanfictions involve him in these complex marriage law - related relationships. Hermione Granger is also popular, as she's a strong and intelligent character. Her presence in a harem - like situation can lead to interesting relationship dynamics. Draco Malfoy is another one. His complex personality and his family's standing in the wizarding world make him a prime candidate for these types of fan - created relationships.
Obviously, Harry Potter himself would be the central character. Then, Hermione Granger could be one of the members of the harem. She is intelligent and has a long - standing friendship with Harry. Ginny Weasley is also a likely candidate as she has a romantic interest in Harry in the original series. Luna Lovegood might be another, with her unique and dreamy personality adding an interesting dynamic to the harem.
In this type of fanfiction, new characters might be introduced as well. There could be other powerful wizards or witches who are either rivals or allies to Harry. Some might be from different magical regions, bringing in new magical cultures and powers. For instance, a powerful wizard from a far - off land who challenges Harry's 'godlike' status. And of course, there are often the antagonists, who are threatened by Harry's power and try to undermine him.
Another type of character could be a collector of magical art. This person might be interested in the prodigy's work and try to either acquire it for their collection or use it for their own purposes. And don't forget about the house - elves. In some fanfictions, a house - elf might be inspired by the art prodigy's work and develop their own form of art, perhaps in the form of beautiful tapestries or carvings. This would add an interesting layer to the story as it shows the influence of the prodigy's art on different members of the wizarding community.
Draco Malfoy is a very typical 'bad boy' in Harry Potter fanfiction. In the original series, he was a bit of a bully, and in fanfiction, this is often exaggerated. He can be portrayed as a brooding, conflicted character who might have a change of heart later. Another one is Sirius Black. His rebellious nature in the books makes him a prime candidate for fanfiction to expand on his 'bad boy' qualities, like his disregard for some of the more traditional pure - blood family values.
Hermione Granger might also be an important character. Given her love for knowledge and books, she could be helping Harry in his journey to master the law, or perhaps they study the law together.
Draco Malfoy is often a central character. His complex personality and his Slytherin pride make him a natural fit in these types of fanfictions. He can be both a love interest and a source of conflict.
Potential characters could range from the well - known witches at Hogwarts to those from other magical institutions. Fleur Delacour could be in the harem, given her beauty and magical abilities. And there could be characters from the wizarding world outside of Britain too. Maybe a Japanese wizard or witch who has unique magical techniques and is drawn to the Harem Lord's power and charisma.
