In Harry Potter different fanfiction, a really interesting concept is time - travel related ones. Imagine if Harry went back in time to change certain events in the wizarding world's history. It could completely change the course of the story. Some fanfictions also play with the idea of different magical cultures around the world interacting with Hogwarts. This could lead to new spells, new forms of magic, and new adventures for the characters.
In some fanfictions, wands might be made from rare materials not mentioned in the original books. For example, there could be wands made from the scales of a magical sea creature, which gives the wands unique properties related to water magic. Another idea could be wands that are passed down through generations and gain extra power with each new wielder.
Some fanfictions feature unique magic related to memory manipulation. Instead of just using the Obliviate spell, there could be a more complex form of magic where one can not only erase but also rewrite memories in great detail. There might also be a type of magic that is based on the constellations, where wizards can draw power from the alignment of the stars. Additionally, a unique magic could be the ability to transform into mythical creatures, not just the Animagus transformation we know from the books, but into something more fantastical like a phoenix or a dragon.
One interesting concept could be a different Sorting. For example, Harry being sorted into Slytherin instead of Gryffindor. This would completely change his relationships and the way his story unfolds. He might have closer ties with the Malfoy family and be more involved in the darker aspects of the wizarding world at first, but then use his influence to bring about positive change from within the Slytherin house.
Some fanfictions under this title might explore a world where the prophecy about Harry never existed. This would mean that Harry's life would be much more ordinary in terms of not having that huge burden on his shoulders. He could focus more on his studies and personal growth, and the wizarding world would also be different as Voldemort's actions might not be as directly related to Harry. It could also lead to different power dynamics among the wizarding families as there's no 'Chosen One' to tip the scales.
One interesting concept could be characters being sorted into different houses than in the original. For example, Neville Longbottom might be sorted into Slytherin instead of Gryffindor. This could lead to a whole new set of character developments and storylines as he has to navigate the Slytherin environment which is known for its ambition and cunning, different from the brave and chivalrous Gryffindor.
One interesting concept could be the creation of new spells. In fanfiction, authors often come up with unique spells that have different effects than the ones in the original books. For example, a spell that can temporarily turn a person into a transparent state, allowing them to pass through walls or avoid detection. Another concept is the exploration of different magical cultures. Fanfiction might delve into a wizarding society from a far - off land with its own set of magical traditions and practices that are completely different from Hogwarts. And some fanfictions explore the idea of magic being used in more modern and technological ways, like using magic to power advanced machines or create new forms of communication.
Well, there could be a concept where a monster girl is actually a guardian of a hidden part of the Forbidden Forest. She has to interact with the Hogwarts students who accidentally stumble upon her territory. Or perhaps a monster girl who is a half - vampire and is struggling with her thirst for blood while also trying to fit into the wizarding world. There are also ideas like a monster girl made of living plants who has a connection to the Herbology department at Hogwarts.
Well, some fanfics have the idea of a time - traveling Defense teacher. For example, a character from the future comes back to teach the subject. This brings in new spells and ways of fighting dark magic that the students haven't seen before.
A really unique fanfiction concept could be one where Snape and Harry time - travel. They go back to key moments in wizarding history and have to work together to fix things that went wrong. This would be an exciting adventure and would force them to rely on each other.
Some fanfictions explore the idea of wands having emotions. For example, in 'The Sentient Wand', the wand can feel joy, sadness, and even love towards its owner. This changes the dynamic of how the wizard - wand relationship is perceived.
