Well, perhaps they travel to a time when their parents were young. They could interact with their younger parents and learn a lot about their family history. For example, Sarada could meet a young Sakura and see how strong and determined she was. Boruto might get to know a different side of Naruto. This could also lead to some really funny or heart - warming moments.
A really interesting plot twist could be that they time travel to a future version of their world that has been completely changed due to some unknown event. They have to figure out what happened and how to get back to their own time. Along the way, they meet versions of their friends and family that are very different from what they know. This would be a great opportunity to explore different character developments and show how the world could be in different circumstances.
In a Boruto Sarada time travel fanfiction, there could be a plot twist where Sarada travels back in time and gets stuck. She then has to use her skills and knowledge from the future to survive in the past. Along the way, she might form unexpected alliances with historical figures. These alliances could be crucial in her attempts to find a way back to her own time. And while doing so, she might also end up influencing the past in ways she never intended, like introducing new ninja techniques prematurely.
Well, perhaps they travel to a time where their parents, Naruto and Sasuke, were just kids. This would lead to some really interesting interactions. They could end up interfering with their parents' early training or friendships. It might also create a situation where they have to be careful not to reveal too much about the future, or else they could disrupt the entire timeline.
One common plot twist could be that Sarada travels back in time and accidentally changes something that has a huge impact on the future of the Hidden Leaf Village. For example, she might prevent an important event from happening that was crucial for the development of certain ninja techniques. Another plot twist could be that she travels back in time and meets a younger version of her parents, Sasuke and Sakura, but they don't recognize her and she has to find a way to prove who she is without revealing too much about the future. Also, she could end up in a time where there is a great threat that was previously unknown in her own time, and she has to team up with past versions of the ninja to defeat it.
Well, a plot twist could be that when Sarada travels back in time, she finds out that her parents' relationship was not what she thought it was. Maybe she discovers that there were other forces at play that almost prevented them from getting together. Also, it's possible that she time - travels to a point where the Hidden Leaf Village is in a much different state than she knew, like being on the verge of a civil war due to some political intrigue that was long forgotten in her time.
In certain fanfictions, a possible plot twist is that Sarada is forced to choose between her loyalty to the village and her friendship with Boruto. If she believes that Boruto's actions are endangering the village, she might end up hurting him. For example, if Boruto is involved in some sort of forbidden jutsu research that the village sees as a threat, and Sarada is put in a position to stop him by any means necessary, including using force.
One common plot twist could be that Boruto travels back in time and accidentally changes something that has a huge impact on the future. For example, he might prevent a key event that led to the development of a certain jutsu, and then has to find a way to fix it before he returns to his own time. Another could be that when he travels back, he discovers a hidden truth about his family or the Hidden Leaf's past that was covered up.
One interesting plot twist could be that when they time travel, they end up in a world where the Uchiha clan was never massacred. Sasuke would have to face a completely different reality where his family is alive, but he also has to figure out how this new world affects the future. Another could be that they travel to a time when a great enemy from the past is still alive and they have to team up with their ancestors to defeat it.
Perhaps a plot twist where Sarada loses her memory and Boruto has to make her fall in love with him all over again. It would add a lot of drama and emotion to the fanfiction. He could show her all the things they used to do together and slowly re - kindle her feelings.
Sarada might develop a greater sense of self - reliance. When she travels through time, she may be on her own without the support she has in her own time. This would force her to trust her instincts more and become more independent.
One possible plot could be that they are on a dangerous mission together. In a moment of near - death, they realize their true feelings for each other and share a kiss. It could be a turning point in their relationship, making them more committed to protecting each other in the future missions.
