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.
A great plot idea could be that the female basilisk is actually a guardian of an ancient wizarding secret. Harry stumbles upon her while exploring a hidden part of Hogwarts. Instead of fighting, they form an alliance to protect the secret from dark wizards who are also seeking it. This would focus on mystery, adventure and cooperation rather than any inappropriate themes.
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.
One plot idea could be that the female Voldemort has a change of heart. Maybe she starts to see the error of Voldemort's ways after interacting with Harry Potter. She could start to secretly help Harry and his friends against the Death Eaters, which would create a lot of internal conflict within the Dark side.
One idea could be that fem Harry Potter and Bill Weasley team up to explore an ancient and forgotten part of the wizarding world. They discover new spells and magical creatures along the way and form a strong friendship based on their shared adventures.
A possible plot could be that the female hippogriff is the key to solving a mystery in Hogwarts. Harry notices some strange behavior from the hippogriff and starts to investigate. He finds out that the hippogriff has a connection to an ancient magic that is hidden somewhere in the school. So, Harry and his friends embark on a journey to uncover the mystery with the hippogriff as their guide. Or perhaps the female hippogriff is a messenger from a far - off magical land, and Harry has to help it deliver its message to the right people in the wizarding world, which involves a lot of adventures and encounters with different magical beings.
One plot idea could be Tonks training Harry in some unique magical skills that she has learned from her time in the Order. This could involve her teaching him how to use certain spells in a more creative way or how to better understand the magic of disguise, given her Metamorphmagus abilities. Another idea is that Tonks and Harry go on a secret mission together to find a lost magical artifact that could turn the tide in the war against Voldemort. Along the way, they face various challenges and have to rely on each other's strengths.
Sure. Some fanfiction might depict a female Harry Potter and Voldemort in a more platonic or mentorship - like relationship. For example, in a story where Voldemort has a change of heart early on and decides to guide Harry (as a female) in the wizarding world, showing her the secrets of magic in a non - evil way. This kind of story would not have any inappropriate content and can be really interesting to read.
Well, here's another plot. Madam Malkin could be visited by a strange wizard who tries to put a curse on her shop. Harry, being the hero he is, comes to her rescue. As they try to figure out who the wizard is and why he targeted the shop, they have to rely on each other's skills and knowledge. This not only shows their friendship but also creates an exciting adventure - filled story.
