What could be the plot of a 'future Naruto goes to the past fanfic'?

The older characters such as Kakashi would be cautious. They would recognize Naruto but also be worried about the implications of someone from the future being in the present. They would want to know if his presence could change the future in a negative way. For example, they might fear that his actions could lead to the earlier awakening of a powerful enemy. As for the villains, they might see future Naruto as a threat and try to eliminate him as soon as possible. Orochimaru, for instance, would be very interested in Naruto's future powers and might try to capture him to study. And the new generation of ninja in the past would look up to future Naruto, seeing him as a symbol of what they could become.

One possible plot could be Naruto going back in time with his red hair. Maybe he has new powers due to some future experiment. He could use his knowledge of the future to prevent certain tragedies in the past. For example, he might stop the Uchiha massacre. His red hair could be a sign of a new form or a side - effect of time travel. He would interact with his younger self and the other characters in a different way, leading to a whole new set of adventures and relationships in the Naruto world.

Well, it could be about Sakura going back in time and trying to change certain events that happened in her life. Maybe she wants to fix a mistake or save someone she lost.

This would lead to a completely different story arc for both of them and for the whole Konoha village.
