One plot idea could be Naruto using his newfound time - stopping ability to prevent a major disaster in Konoha. For example, he could stop time just as a powerful enemy's ultimate attack is about to hit the village, and then find a way to counter it while time is frozen. Another idea is that Naruto uses it to have some peaceful moments with his friends and family that are always cut short in the normal flow of time. He could share a meal with his dad, Minato, and have a long conversation that was never possible before.
One plot idea could be that Naruto, while pregnant, travels back in time to the founding of Konoha. He uses his knowledge of the future to prevent certain tragedies from occurring during the village's creation, all while dealing with the physical and emotional challenges of being pregnant in a different time.

One idea could be Naruto using his time - skip ability to go back and prevent certain tragedies in the ninja world, like the Uchiha massacre.

Another could be that he skips forward in time to see the potential outcomes of his actions in the present, and then uses that knowledge to make better decisions in the current time.
One plot idea could be Sakumo traveling back in time to prevent his own death. This would change the course of Naruto's world as his father's death had a big impact on Kakashi, who in turn influenced Naruto. Another idea is Naruto traveling back to meet Sakumo and learn some long - lost jutsu from him. It could also be that they both travel back to a crucial point in Konoha's history and work together to save the village from a greater threat that was previously not averted.
One interesting plot idea could be that Naruto and Shizune travel back to the time when the Uchiha clan was still intact. Naruto, with his knowledge of future events and his never - give - up attitude, tries to prevent the Uchiha massacre. Shizune, with her medical skills and calm demeanor, helps him by treating any injured people along the way. They could face challenges like convincing the Uchiha clan to trust them and dealing with the political intrigue in the village at that time.
One idea could be Naruto going back to the time when the Uchiha clan was still intact. He could try to prevent the massacre by changing certain events or by influencing key people.

One idea could be a story where Naruto discovers a new, ancient space - time jutsu that allows him to travel to alternate universes. In these universes, he meets different versions of his friends and enemies, and has to find a way to return home while also dealing with the chaos caused by the jutsu's power.
Maybe Bolt travels back to a time when the Akatsuki was at its peak. He could use his knowledge of future events and his own skills to try and take on the Akatsuki, creating a whole new set of battles and alliances. For example, he might form an alliance with Itachi before his death and together they could try to take down the other Akatsuki members.
A possible plot could be that the genderswapped Naruto time - travels to the time of the Third Ninja War.

She might also have a different approach to the war, perhaps trying to find diplomatic solutions instead of just relying on combat, due to her different perspective as a genderswapped character.

One idea could be that Naruto travels back in time and joins the Anbu at a young age. He uses his future knowledge to prevent certain tragedies within the Anbu, like stopping betrayals.

Maybe he tries to stop the Anbu from being misused by certain corrupt elements in the village.
