Well, Draco Malfoy can also be involved in some cases. He could be either a rival who tries to disrupt the harem or, in some unique fanfictions, a part of the harem himself. Luna Lovegood might be included too. Her dreamy and eccentric nature can bring a different flavor to the harem. And then there are the professors like Snape. In some fanfictions, he could play a role in relation to the hypnosis, perhaps as a mentor figure or someone who has knowledge about the dangerous side of the hypnosis magic that the characters need to be aware of in the context of the harem situation.
Harry Potter himself is often a common character. He might be the one who accidentally stumbles upon the hypnosis magic and ends up with a harem. Hermione Granger is also frequently included. Her intelligence could be used in different ways in the story, like helping to understand the hypnosis magic better or being an important part of the harem dynamic. Ginny Weasley is another character that can be part of the harem. She has her own strong - willed personality that can add interesting twists to the story.
Oliver Wood is another character that might be in such fanfiction. He's extremely passionate about Quidditch. In a harem - related Quidditch fanfiction, he could be the object of affection for some students who are attracted to his dedication and skill on the pitch. Also, the Weasley twins, Fred and George, could be involved. Their mischievous nature combined with their Quidditch skills might draw a group of followers or love interests.
Ron Weasley could be there too. He might be a bit more clueless at first about the hypno harem situation but would still be dragged into it. And of course, there could be some original characters created just for these fanfictions. They could be new students or mysterious wizards who are either causing the hypno or are part of the harem that forms.
Harry Potter himself is often involved. Writers might explore how he could be hypnotized to face his inner demons or unlock new powers. Hermione is also a popular choice as her intelligence could be enhanced or her memories explored through hypnosis.
Harry Potter is at the heart of it. But don't forget about Pansy Parkinson. In some fanfictions, she can be rewritten to have a different side to her and be part of Harry's harem. Then there's also Daphne Greengrass. Her family's status in the wizarding world could play a role in a story about a marriage contract harem, and she could be one of the characters vying for Harry's attention.
Hermione Granger might also be a key character. She's so intelligent that she could be the one to study and figure out how to control or counter hypnosis powers. For instance, if there's a new threat in the wizarding world related to hypnosis, Hermione would be the one delving into the library to find solutions. And of course, there could be original characters created specifically for these fanfictions. These could be new students at Hogwarts who have a natural affinity for hypnosis powers and get involved in all sorts of adventures with the well - known Harry Potter characters.
Harry Potter himself is obviously a central character as the focus of the so - called 'harem'. Hermione Granger could be one of the likely characters involved. She is Harry's close friend in the original series and her intelligence and magical abilities would make her a strong contender in any relationship - based competition. Ginny Weasley is also a likely character, as she has a romantic relationship with Harry in the official story. Luna Lovegood might be included too, with her unique personality and magical insights.
Hermione Granger is also a common character. Given her love for knowledge and her skills in magic, she would likely be researching the best spells and magical theories to make the terraforming successful. She might be the one to find ancient spells that are crucial for the process.
In many expelled Harry Potter fanfictions, the Weasley family as a whole gets involved. Molly Weasley would be worried sick about Harry and would be cooking up plans to get him back. Fred and George might use their prank - making skills to expose the truth behind the expulsion. Ginny, being Harry's love interest in the original series, would be actively involved in trying to clear his name. And don't forget about the Hogwarts professors. McGonagall would probably be torn between following the rules and believing in Harry.
Harry Potter himself is often a central character. He might be shopping for new school supplies at Flourish and Blotts or looking for a new broomstick at Quality Quidditch Supplies. His friends, like Hermione and Ron, usually accompany him. Hermione might be more interested in books and rare magical artifacts, while Ron would be eyeing the latest Quidditch gear.
Mrs. Weasley is a very likely character. She's an expert at cooking and baking in the normal wizarding world, so in fanfiction about magical bakes, she could be teaching the younger characters how to make special bakes. Hagrid might also be involved. He could bring in some really strange ingredients from the Forbidden Forest, like giant acorns, to be used in the bakes.
