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 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.
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.
In such fanfictions, one interesting concept could be the reimagining of magic spells. For example, the spells might have different incantations or effects. Another concept could be the alteration of magical creatures. They might have new behaviors or abilities. Also, the role of Hogwarts could be changed, like it having different houses or teaching methods.
One interesting concept could be the idea of a life debt being repaid in unique ways within the wizarding world. For example, a character might sacrifice their own magical abilities to save another who they owe a life debt to.
One interesting concept could be the moral implications of life - draining magic. It makes you think about the boundaries of magic in the Harry Potter universe. Another could be how it affects the characters who perform it or are victims of it, like a dark turn for a usually good character who is tempted by this power.
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.
One interesting concept could be if Harry was raised by the Malfoys instead of the Dursleys. He might have grown up with a very different view of the wizarding world, perhaps more aligned with the pure - blood supremacist ideas at first. Then his journey to discover the truth about Voldemort and the importance of equality could be a completely different and more complex story.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book.
