There are numerous examples. Consider the character of Luna Lovegood. Over time in fanfiction, she could become a leading figure in the study of magical creatures, far more influential than she was in the original series. Time can also change the way magic is taught at Hogwarts. New methods could be introduced, replacing the old ones. And in terms of the wizarding society, time might bring about a more inclusive environment. Pure - blood supremacist ideas could fade away as time passes, and Muggle - born wizards could gain even more equality, which is a significant change from the initial state of the wizarding world in the original story.
In Harry Potter fanfiction, we often see time changing character identities. For instance, Neville Longbottom, who was initially seen as a bit of a bumbling wizard - in - training, could become a very powerful and respected figure as time goes on. Time can also change the nature of magic. Old magic that was thought to be lost might be revived. And relationships are a big area. Hermione and Ron might drift apart over time in some fanfictions, and Hermione could form a new bond with someone else, completely changing the romantic dynamics of the story.
One example could be the change in Hogwarts over time. Maybe in some fanfictions, with the passage of years, the layout of the school changes, new rooms are discovered. Another example is the relationship between characters. Harry and Draco might start as bitter enemies, but as time passes in the fanfiction, they could become reluctant allies. Also, time could change the power dynamics in the wizarding world. A small, insignificant family could rise to power over time.
In Harry Potter fanfiction, time can change everything by allowing characters to grow and develop. For example, as years pass, young wizards become more powerful and experienced. Their relationships also evolve. Friends might become enemies or vice versa over time. The wizarding world itself can change, with new spells, creatures, or political situations emerging as time goes on.
Well, 'The Slytherin Time Traveler' is a good one. It shows how a Slytherin who time travels has to deal with the different values and cultures of the past. They might face challenges from other houses who don't trust Slytherins, especially when they seem to know too much about the future. Another example could be 'Back in Time: Slytherin's Redemption'. Here, a Slytherin character travels back to try and change the bad reputation of the Slytherin house throughout history by influencing certain key events and people.
One great example is 'The Time - Turner's Redemption'. In this fanfiction, Harry uses the time - turner in a new and creative way. He goes back to key moments in the wizarding world's history and changes small things that have a big impact on the future. Another is 'Harry Potter and the Temporal Paradox'. Here, Harry travels through time to prevent Voldemort from ever getting the idea of creating Horcruxes.
One consequence could be an alteration in the relationships. For example, if he saves Sirius, the relationship dynamics between him, Remus, and the other members of the Order would be different. They might be more united and effective in fighting against the Death Eaters.
In fanfiction, 'Harry Potter remembers everything' can be a really interesting concept. It might mean that Harry has a perfect recall of all his experiences, including the traumas. This could lead to him being more strategic in dealing with Voldemort and his followers. For example, he could remember every detail of a Death Eater's spellcasting pattern and use that knowledge to his advantage in battles.
Some interesting ideas include changing the way magic is taught at Hogwarts. In the fanfiction, perhaps they could introduce new spells or magical theories that were not in the original books. Also, the fates of the Weasley family members could be different. Maybe George could have found a way to bring Fred back to life in this alternate version. And, of course, the fate of Voldemort could be changed, like he could have been redeemed instead of being the ultimate villain.
One interesting concept could be the change in relationships. For example, characters who were enemies in the original series might form unexpected alliances in this fanfiction. Another could be the alteration of magical abilities. Maybe a character discovers a new and unique magical power that changes the power dynamics in the wizarding world.
Well, in some nightmare fanfictions, Harry Potter might find out that his parents were actually evil all along. This completely changes his view of himself and his place in the wizarding world. Another example could be a fanfic where the magical world is slowly being destroyed by a mysterious force and the characters are powerless to stop it. It creates a very dark and hopeless atmosphere for the story.
One example could be a fanfiction where a character acts completely out of character in a cruel way towards others, like Harry Potter suddenly turning on his friends without any real motivation. Another might be a story that twists the original themes of love and friendship in the series into something cold and unfeeling.
One example could be a fanfiction where Harry Potter visits an Indian wizarding school that has its own unique houses based on Indian values like Dharma, Karma, etc. Another could be a story where Hermione has an Indian heritage and uses Indian magic spells along with the regular ones from the original series.
