A lot of these fanfictions play around with the idea of changing destiny. In many of them, when Harry and Voldemort meet during time travel, they end up having to work together to fix some sort of magical catastrophe that their future selves created. This often leads to some very strange and unexpected alliances between the two arch - enemies.
One great fanfiction could be 'The Prankster's Plot Against the Dark Lord'. In it, Harry uses a series of clever magical pranks, like turning Voldemort's wand into a rubber chicken for a short while during a battle. It adds a touch of humor to the dark and dangerous world of Harry Potter and Voldemort's enmity.
One great fanfic in this genre is 'Back to the Start'. It has an interesting plot where Harry goes back in time and meets his father, James. The interactions between them are really well - written, showing a different side of James Potter.
One great fanfiction in this genre is 'The Time - Twisted DADA Teacher'. It has an interesting plot where the DADA teacher from a future time travels back to Hogwarts during Harry's time. The character development is well - done and it weaves in elements from the original series in a creative way.
One great 'Harry Potter Time Travel Fix It' fanfiction is 'A Time to Change' where Harry goes back and changes key events. It has a really interesting take on how his knowledge of the future can be used to prevent tragedies.
I've read a fanfic where Dumbledore is evil due to a time - travel accident. In the story, a spell during time travel goes wrong and alters Dumbledore's personality. Harry has to figure out what happened and how to fix it. The story is really detailed in exploring how the Hogwarts community reacts to an evil Dumbledore. It shows how the relationships between the characters change and how the power dynamics shift. It's a great read if you like exploring different interpretations of the Harry Potter universe.
If Voldemort reads Harry Potter books fanfiction, it could be really strange. He might get angry as the fanfiction could portray him in ways he doesn't like. Maybe he'd see himself being defeated in new and creative ways that would irritate his pride. He could also gain some new, unexpected insights about the wizarding world from the different perspectives in the fanfiction, which could either make him more dangerous or, if he overthinks it, cause him some confusion.
One great 'Harry Potter Time Travel Fanfic' is 'All the Wrong Choices'. It offers a really interesting take on how time travel could change the course of the original story.
I've read a fanfic where Harry and Rowena time travel called 'Time's Whimsical Voyage'. In it, their interaction during the time - traveling escapades is so well - written. It shows how Rowena's ancient wisdom combines with Harry's modern - day courage. The author does a great job of making the time - travel mechanics believable and exciting.
A really good one is 'Voldemort's Redemption'. This fanfiction flips the script a bit. It explores the possibility of Voldemort being redeemed. It's a fascinating read as it shows how Harry might react to a Voldemort who is trying to change. It also has some great descriptions of the magic and the Hogwarts environment, making it feel like a natural extension of the Potterverse.
One popular theme is redemption. Some fanfics show Voldemort getting a chance to change his ways through time travel. For example, he might see the error of his future actions when he meets a young Harry. Another theme is the exploration of their relationship. Since they are such strong enemies, seeing how they interact in different time periods is fascinating.
