Fanfiction about Harry going back to Marauders' time: What are some interesting plot twists?

In 'Harry go back to the marauders time fanfiction', a really engaging plot point is Harry's internal struggle. He has to decide whether to interfere with the past or not. On one hand, he might be tempted to save his parents from their tragic fate. But on the other hand, he knows changing the past could have huge consequences. This conflict within him can drive the whole story. Also, his relationships with the Marauders are key. How does he fit into their friendship? Does he become a new member of their group? Or is he more of an outsider trying to help from the sidelines?

A possible plot twist is that Kakashi goes back in time and finds out that the events he thought were true in the past were actually misinformation. This could completely change his perception of the history of the ninja world and his own role in it. Also, he might go back to a time when Orochimaru was just starting his dark experiments. Kakashi could try to stop Orochimaru right from the start, but in doing so, he might end up creating new villains or problems. Or perhaps, when he travels back, he loses some of his memories from the future, which makes it difficult for him to use his knowledge effectively to change things.

A plot twist could be that they end up in the wrong time period completely. Instead of the time they intended to go to, they land in a much earlier era of magic. There, they discover secrets about magic that have been long forgotten in their time. However, they also face the danger of getting stuck there because the magic that sent them back was calibrated for a different time, and they have to find a way to adapt it to return home.

One interesting plot twist could be that when they go back in time, they accidentally change a small event that has huge ramifications in the future. For example, they might prevent a key Hollow attack that was originally supposed to happen. This would then change the relationships between characters. Maybe Ichigo doesn't meet some of his friends in the same way because that Hollow attack was a catalyst for many things in the original timeline. Another plot twist could be that they find out there's a hidden force that has been manipulating time all along and they have to fight against it to set things right. And a third could be that when they go back, they discover that their own powers work differently in the past, which adds a whole new layer of challenges for them to overcome.

One plot idea could be Harry going back to the time when Voldemort was still at Hogwarts as Tom Riddle. He could try to prevent Riddle from turning into Voldemort by befriending him and showing him a different path. Another idea is that Harry goes back to the time of the founders of Hogwarts. He might learn ancient magic directly from them and use that knowledge to change the future of the wizarding world. Also, he could go back to a time when his parents were alive and get to know them better, which would be a very emotional journey for him.

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.

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.

A great plot twist could be related to the time - travel itself. What if the way time - travel works in the WW2 era is different from how it is in Harry's time? This could lead to him getting stuck or being unable to use his magic properly. Or perhaps he discovers that a certain event in WW2 was actually caused by a wizard from the future (not just him) who was trying to correct something in the wizarding world's past. His attempts to fix things could then make the situation even more complicated as he unknowingly steps on the toes of a much larger time - traveling plan.

Well, perhaps a plot twist could be that when Kirito goes back in time, he discovers that his own existence in the past was a key factor in creating the problems he faced in the future. So, he has to figure out a way to change things without erasing himself. Or, he could go back and find that the person he loves in his original timeline has a completely different personality or role in the past, which throws him off and makes his feelings really complicated.

A cool plot twist might be that Fem Harry goes back in time and discovers that her parents were involved in a secret mission that was never revealed before. This could lead to her having to deal with the consequences of uncovering that truth. Also, she could find out that Voldemort had a different origin or a hidden weakness that was lost in history. As she tries to use this knowledge to defeat him earlier, she might face opposition from some of the older wizards who don't believe her or are afraid of the changes she could bring. It could also be that she changes the way magic is taught at Hogwarts, introducing new spells or techniques from the future that create a whole new set of challenges and opportunities for the students.
