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.
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.
I'm not entirely sure. Fanfiction can cover a huge range of ideas, and while time travel in Harry Potter is a common theme, and Orochimaru is a well - known character from Naruto. The combination seems a bit out there. But, if you search on some major fanfiction platforms like Archive of Our Own or FanFiction.net, you might be able to find out for sure if such a fanfiction exists.
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.
A great fanfiction idea could be that James Potter time - travels during a crucial battle in the wizarding world. He travels back to a time when the dark forces were just starting to rise. With his future knowledge, he could start preparing the wizarding community earlier. He could train young wizards and witches in advanced defensive magic, and try to change the course of history so that the big battle he left behind would have a different, more positive outcome.
One great older Harry Potter time travel fanfiction is 'The Time - Turner Conundrum'. In this story, Harry accidentally travels back in time much further than he intended. It's full of interesting twists as he has to deal with a Hogwarts that's very different from what he knows, and he has to figure out how to get back to his own time without changing history too much.
Another interesting fanfiction plot could be about a descendant of Salazar Slytherin who time - travels. They go back to the time of the Basilisk with the intention of taming it. They believe that the Basilisk was misused in the past and that they can change its fate. They might have to face many challenges, like the opposition from other wizards at that time who fear the Basilisk's power.
One possible fanfiction idea could be that a character discovers a time - traveling device while exploring the Chamber of Secrets where the Basilisk once lurked. They accidentally travel back in time to the era when the Basilisk was first created or when Salazar Slytherin was alive. This could lead to all sorts of adventures, like trying to prevent the Basilisk from being created or changing the course of Hogwarts' history regarding the Chamber.
One idea could be a Hufflepuff student discovers a time - turning device in the Hufflepuff common room. They decide to travel back in time to meet the founders of Hogwarts. They end up learning valuable lessons about loyalty from Helga Hufflepuff herself.
I also like 'A Second Chance at Life'. This fanfiction focuses on a character getting a chance to go back in time and correct their mistakes. It's a more emotional take on time travel in the Harry Potter universe. The author does a great job of exploring the character's feelings and how they deal with the knowledge of the future.
