Here's an interesting plot. There is a new potion that has mind - controlling properties. A group of Slytherin students, in an attempt to gain an advantage in the House Cup, decide to use it on some Gryffindor students. But things go awry as the mind - controlled students start to exhibit strange and dangerous behavior. Harry and his friends then have to not only break the mind control but also deal with the consequences and the blame that is wrongly placed on them. This kind of plot can explore themes of loyalty, friendship, and the consequences of unethical magic use without any inappropriate 'lemon' content.
One interesting idea could be the exploration of how the mind control aspect alters the relationships in the harem. For example, it might create complex power dynamics where characters are forced to interact in new ways.
Another aspect could be the moral implications of mind control in the wizarding world. Fanfics might delve into how society views those who use mind control, whether they are seen as pure evil or if there are gray areas, such as using it for self - defense in a life - threatening situation.
A really interesting plot could be that Catelyn Stark is mind - controlled as part of a larger political scheme. The mind control is used to make her seem unreliable in the eyes of the other lords, so her family's position is weakened. However, she starts to have flashes of her true self and uses these moments to send coded messages to her family. As she struggles to break free, she also has to deal with the political fallout of her actions while under the mind control. This could lead to a complex and engaging story that focuses on her strength and determination.
One interesting 'Harry Potter mind control fanfiction' could be about a spell gone wrong that causes mind control in Hogwarts. Maybe a student accidentally casts a spell on the whole Gryffindor house, making them do silly things like dance in the Great Hall all day. Another could be a dark wizard using mind control on some of the teachers to gain access to the restricted section of the library. There are also those where Voldemort tries to use mind control on Harry in a different way than in the original books, perhaps through a magical artifact.
One idea could be a powerful vampire using mind control to make Elena forget her love for Stefan and fall for him instead. This would create a lot of drama as Stefan tries to figure out what's wrong and win her back.
One idea could be a villain using mind control to turn the young heroes against each other. They start fighting among themselves, creating chaos within the team. This can lead to a lot of character development as they struggle to break free from the control and regain their trust in one another.
One idea could be that a female Harry Potter discovers a time - travel spell and goes back in time to try and prevent Voldemort from ever becoming evil. She could try to befriend him as a child, show him kindness, and change the course of history. This would create a very different wizarding world and an interesting dynamic between the two characters.
One idea could be that a centaur saves Harry from a dangerous creature in the Forbidden Forest and then they form a bond. The centaur could teach Harry about the ancient magic that the centaurs possess. Another plot could be a centaur acting as a guide for Harry during his search for a rare magical herb that only grows in centaur - protected areas. They would have to work together to overcome various obstacles.
One idea could be that a Succubus is a new kind of magical creature discovered in the Forbidden Forest. The Hogwarts students and professors have to figure out how to deal with it, whether it's a threat or not. Another could be a Succubus who has lost her powers and comes to Hogwarts seeking help to regain them in a non - sexual way, like learning about different kinds of magic.
One idea could be that Wanda Maximoff is transported to the Harry Potter universe. She could use her powers to help Harry and his friends during the Battle of Hogwarts. Her ability to manipulate energy and reality could give them an edge against Voldemort and his Death Eaters.
