Sometimes, in these fanfictions, the time - travel itself is a plot twist. They might think they are traveling back in time, but actually end up in an alternate dimension that just looks like the past. They then have to figure out the rules of this new dimension while still trying to get back to their own world. This adds an extra layer of mystery and adventure to the story.
Another popular plot twist is that when they travel back, they find out that the past isn't exactly as they remembered it. There could be some hidden secrets or different motives of the characters they thought they knew well. For instance, they might discover that a certain villain had a more complex backstory and wasn't always evil. This changes their perspective on how to deal with things in the past and future.
In some Sakura and Sasuke time travel fanfictions, a great plot twist is that they time travel to a point where they meet their younger selves. This can lead to some really complex and emotional situations. The younger Sasuke might not trust the future Sasuke, thinking he's an imposter or has been corrupted. The same could go for Sakura. Another plot twist could be that the time travel is caused by a forbidden jutsu that Sakura accidentally activates. And as they travel through time, they start to lose their memories bit by bit, adding a sense of urgency to their journey to get back to their own time and figure out what's going on.
One popular plot twist is when they travel back and find out that the events they thought they could easily change are actually much more complex due to some hidden forces at work. For example, in some fanfics, they discover that an ancient jutsu is behind all the chaos and they have to find a way to break it.
A common plot twist is that during their time travel, they find out that they are fated to be together in a yaoi relationship in all timelines. So, they have to figure out how to make it work in the past while also dealing with the knowledge that they are from the future. It could also be that the time travel is caused by a powerful yaoi - themed magic or jutsu that has some unforeseen side effects, like making them more in tune with each other's emotions on a romantic level, which then leads to all kinds of interesting interactions and decisions as they navigate their past and future.
Maybe they travel back to their early days at the ninja academy. Naruto, who now has all his future knowledge, tries to befriend Sasuke in a different way. But Sasuke, being suspicious, thinks Naruto has some ulterior motive. This leads to a whole new set of comical and at the same time tense interactions between them as they both have to deal with their past selves and the changes they want to make.
A cool plot twist might be that when Sasuke travels back in time, he finds out that his actions in the future were actually part of a grand plan set by an ancient Uchiha. So, all his attempts to change things are just following the script that was already written. Also, he could time travel to a time when the Uchiha were at the height of their power and he has to deal with the jealousy and suspicion of other clans who see him as a threat because they know what the Uchiha will become in the future.
One great Sasuke, Naruto, and Sakura time travel fanfiction is 'Time - Twisted Bonds'. In this story, they are sent back to their childhood days with their present - day knowledge. It's really interesting to see how they interact with their younger selves and try to change things for the better. Another good one is 'Journey Through Time' where they travel to different points in the Naruto timeline and face challenges that were not part of the original story.
One possible plot twist could be that when they travel back in time, they accidentally change something that makes their future relationship even more complicated. For example, they might prevent an event that was crucial for their initial bond. Another could be that they end up in a time where their personalities are very different, like a more war - hardened Naruto in the past, and they have to re - learn to love each other. Or perhaps they travel to a future where their love has been forgotten, and they have to rekindle it while also dealing with the new world they find themselves in.
One common trope is changing the past. For example, in many fanfictions, they go back in time to stop a major event like the Uchiha massacre. This gives the characters a chance to rewrite history in a way that could have a huge impact on the Naruto universe. Another trope is the fish - out - of - water scenario. Since they are from a different time in their own world, they often have to adapt to the ways of the past, which can lead to some funny and interesting situations.
A great plot twist could be that they time travel into the bodies of their younger selves but with their current godlike powers. They then have to deal with the reactions of their friends and family who don't understand what has happened to them, while also trying to use their new - found situation to prevent some future disasters.
One interesting plot twist could be that fem Naruto, instead of being the underdog like in the original story, is immediately recognized for her potential in the past due to her different appearance. Another could be that Sasuke, upon time traveling, tries to change things for the better but accidentally sets off a chain of events that makes the situation even worse. For example, he might try to stop certain tragedies from happening, but in doing so, creates new enemies or problems.
