In a Team 7 Naruto time - travel fanfiction, they could end up in a parallel universe during a time of great chaos. They have to figure out how to get back home while also dealing with the differences in this new world. Naruto would try to bring hope as he always does. Sasuke would be analyzing the power structures, and Sakura would be using her medical skills to help those in need during the chaos.
One interesting fanfiction idea could be that Team 7 time - travels back to the era of the First Hokage. They could witness the founding of Konoha and interact with the early shinobi. Naruto might be shocked to see how different yet similar the village was in its infancy. Sasuke could gain new insights into the Uchiha clan's history from that time, and Sakura might learn about the early medical ninjutsu practices.
One possible story could be that Team Minato time travels to the future. They would be amazed by the technological advancements. Naruto might be excited to see how the village has grown. They could also learn new jutsu from the future ninjas and take that knowledge back to their own time to strengthen Konoha.
In a time - travel Nagato fanfiction, he could travel to the future. He'd be shocked to see how the world has changed. Maybe he'd find that the ninja world has achieved peace through different means than he had envisioned. He could then return to his own time and try to implement some of those future ideas in his own era, like new ways of training ninjas or diplomatic strategies between villages.
Maybe Team 7 travels back in time to a period when a powerful and evil force first emerged. They then try to stop this force from growing in the first place. Along the way, they face challenges like not being recognized by the people of that time, and having to adapt to the older ways of doing things in the ninja world. They might also encounter versions of their own families or friends in the past and have to deal with the emotional turmoil of seeing them but not being able to fully interact as they are from different times.
There's also 'Back to the Beginning: Team 7's Time Travel'. Here, Team 7 travels back to a crucial point in the Naruto universe's history. They end up changing some small things which have big consequences later. It's full of action and the character development is really well - done.
One possible scenario in such a fanfiction could be that Jiraiya's son discovers a forbidden jutsu that allows him to time - travel. He decides to go back in time to prevent some great tragedies in the Naruto world. He might try to stop the Uchiha massacre, which would change the whole dynamic of the story. This could lead to different alliances and power structures, as Sasuke wouldn't have the same motivation for revenge.
In this type of fanfiction, the time travel might be a result of a forbidden scroll or an experiment by a rogue ninja. When Naruto and Sasuke go back in time, their relationship is different from what it was in their original time. The kiss could be a turning point where they start to understand their feelings for each other on a deeper level, perhaps realizing that their bond is stronger than just friendship or rivalry.
In this fanfiction, Naruto's time travel to meet Minato could involve family secrets. Maybe there's a special family jutsu that only Minato was supposed to pass down but couldn't due to his early death. When Naruto arrives, Minato decides it's time to teach him this secret family technique. This could strengthen their family bond further and also give Naruto an edge in his future battles.
One possible fanfiction could involve Gaara and Naruto going back in time to the Chunin Exams. They might use their knowledge of future events to change things for the better. For example, Naruto could try to prevent some of the more tragic events that occurred during the original exams, like the death of some of the minor characters. Gaara, on the other hand, might be more focused on changing his own past actions and how he was perceived during the exams.
One interesting fanfic could be 'Naruto: The Fox's Time Leap'. In this, Naruto's transformation into a fox might be related to some ancient jutsu that also enables time travel. He could use his new fox - like abilities and knowledge from the future to change past events and save the Hidden Leaf in ways he couldn't before.
A possible plot twist could be that when they travel back, they find out that the past is not as they remembered it. Maybe some events were actually caused by an unknown enemy manipulating things from the shadows all along.
