Fanfiction about Harry Potter time travel do - over: What are some interesting plot twists?

One interesting plot twist could be that Voldemort is actually being controlled by an even darker force all along. In the original series, Voldemort seems to be the ultimate evil, but in a 'do over' fanfiction, this new revelation would completely change the power dynamics and the goals of the heroes.

In some fanfics, a time - traveler might end up being the cause of Grindelwald's rise instead of stopping it. For example, in 'The Unintended Consequence', the main character's actions in the past accidentally give Grindelwald more power.

Maybe Harry travels back in time and discovers that the person who put his name in the Goblet was actually an older version of himself trying to change the past for some reason. It could be that in the future, something really bad happened and he thought by changing this event in the past, he could prevent it. This would create a really complex and mind - boggling time - travel paradox.

Perhaps Harry Potter travels back in time and ends up befriending a younger Bellatrix. He could try to influence her to not become a Death Eater. This would create a really complex situation because he has to balance not changing too much of the future while also trying to save her from the dark path. It could lead to some really intense moments where Harry has to hide his true identity and motives from her.

One interesting plot twist could be that every time Harry repeats the day, a different character becomes aware of the time loop. For example, in one loop it's Hermione who figures it out and tries to help Harry break the loop in a very scientific way, using her vast knowledge. Another could be that Voldemort somehow gets a hint of the time loop and tries to use it to his advantage, like setting up different traps for Harry each time the loop restarts.

One interesting plot twist could be that Harry goes back in time and accidentally changes the sorting of some of the characters. For example, Draco Malfoy could end up in Gryffindor instead of Slytherin, which would completely change their relationship and how events unfold in the wizarding world.

Perhaps in the fanfiction, when time is turned back, Hermione decides to focus on different areas of magic. Instead of being all about books and rules, she starts to explore dark magic in order to stop Voldemort before he rises. This could put her at odds with Harry and Ron. Also, if time is turned back far enough, Dumbledore could be a student again. He might make different choices that change the whole wizarding world's future, like not getting involved with Grindelwald, which would have a huge impact on the events leading to Voldemort's rise.

A possible plot twist is that Naruto's time travel sends him to a parallel universe instead of his own past. In this universe, all the characters he knows have different personalities or roles. For example, Sasuke could be a happy - go - lucky person instead of brooding and revenge - driven. Naruto would then have to adapt to this new world while also trying to find a way back to his own universe. Or, he could find out that in this parallel world, the Akatsuki are the good guys, and he has to reevaluate his views on good and evil.

One interesting plot twist could be the seer seeing a future where Voldemort is actually a puppet of a more powerful dark wizard hidden in the shadows. This would completely change the power dynamics in the wizarding world.

Perhaps the person who initiates the time travel isn't who they seem. It could be an imposter who has their own motives for changing the past, like a Shadow in disguise. This would add a whole new layer of mystery and danger to the story.
