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.
Typically, you might see some original characters added to the mix as well. These original characters could be designed specifically to be part of the yandere harem. They might be from different wizarding families or even from other magical creatures' clans. For example, a veela - like character who has a yandere - like obsession with Harry. And of course, some of the male characters from the original series might also be involved in different ways, either as rivals or as friends who are trying to understand what's going on with the yandere harem around Harry.
Often, the yandere harem would include characters who are usually on Harry's side in the original series. But in the fanfiction, they are given a new dimension with the yandere aspect. Luna Lovegood could be an interesting addition to the harem. Her dreamy and somewhat eccentric nature could be twisted into a yandere - like love for Harry. And then there are the professors, who in some fanfictions, might play a role in either controlling or being affected by the yandere harem around Harry.
