Scorpius Malfoy is another likely main character. His family's history and his own inquisitive nature would make him an interesting addition. He might be the one who discovers the time - travel mechanism. His relationship with Albus Potter could also be explored further as they embark on this time - traveling adventure together, and his views on his family's past actions could change during the journey.
One idea could be that the new generation discovers a time - turning device left by Hermione. They travel back to the time of the first Triwizard Tournament. There, they meet a young Sirius Black and Remus Lupin, and get involved in the mystery surrounding Cedric Diggory's death in a new way.
A really popular Harry Potter time - travel fanfiction is 'The Time - Traveling Trio'. In this story, Harry, Hermione, and Ron are sent back in time for some unknown reason. They have to figure out how to get back to their own time while also dealing with the differences in the past. For example, they encounter younger versions of their professors and have to be careful not to reveal too much about the future. It's full of adventure and mystery, and the author does a great job of staying true to the characters' personalities.
Scorpius Malfoy is often a popular character. He's the son of Draco Malfoy, and in fanfics, he can be portrayed as a complex character with his own moral struggles, often forming interesting relationships with the children of Harry Potter and his friends.
Lily Luna Potter might also be a main character. She has a strong personality and her own set of skills. Her presence in the time - travel plot could bring a different perspective, especially when it comes to interacting with the female characters from the past.
One idea could be that the next - generation characters travel back to the time of the first wizarding war. They could accidentally change some small events, which then have big consequences on their present time. For example, they might prevent a certain spell from being cast that was crucial in the defeat of a dark wizard, and now they have to figure out how to fix it in their own time.
One great fanfic could be about how the Time - Turner is rediscovered in the next generation at Hogwarts. A young wizard, perhaps the son or daughter of a well - known character, stumbles upon it. They then have to face the moral dilemma of using it, just like Hermione did in the original series. It could lead to some really interesting adventures where they try to correct past mistakes or prevent future disasters.
One interesting storyline could be about the new generation of wizards facing a new dark magic threat that is a combination of old and new spells. They have to use their unique skills and the knowledge passed down from their parents' generation to combat it.
The idea of time travel in the Harry Potter world is appealing because it allows for so many possibilities. We can see how the past might have been different or how characters could change the future. It's like exploring uncharted territory within a familiar universe.
Well, in some fanfics, time travel is more complex. There might be special portals or ancient magic that allows for time travel. For instance, there could be a hidden chamber in Hogwarts that holds the key to traveling through time. And the consequences of time travel can range from minor changes in the present to completely rewriting the future of the wizarding world. Sometimes, characters find that they can't change certain events because they are 'fixed points' in time, much like in some theories of time travel in other science - fiction and fantasy works.
