One idea could be exploring the emotions of Hinata during the birth. Maybe she's worried about Boruto's future in a world filled with challenges. Another could be how Naruto, as a new father, is torn between his duties as Hokage and being there for his family. For example, he might have to leave Hinata's side during the birth to deal with a sudden threat to the village, and then rush back to be with his new - born son.
Perhaps the fanfiction could focus on the medical ninjas involved in Boruto's birth. They could face some unexpected difficulties during the delivery, like a rare complication due to Hinata's unique bloodline. This would create a tense situation where they have to use all their skills and knowledge to ensure a safe birth for Boruto and the well - being of Hinata.
One idea could be how Naruto's early birth might change his initial training. Maybe he'd be weaker at first due to being born prematurely, but then develop unique skills to compensate. Another might be the impact on his relationships. For example, his bond with Iruka could be even stronger as Iruka might take on more of a parental role earlier.
Another plot could involve them exploring a mysterious new area. This new place has strange creatures and unknown powers. They start to learn about the secrets of this area and how it might be related to the future of the ninja world. As they explore, their friendship deepens and they also face challenges that test their loyalty to each other.
One idea could be that they go on a secret mission together. During the mission, they face various challenges that test their skills and teamwork. This could lead to a deeper understanding and bond between them.
One idea could be an OC who is a foreign exchange student from a far - off land in the Boruto universe. They bring unique jutsu or cultural elements that no one in Konoha has seen before. This could lead to interesting interactions with the main characters as they learn from each other.
One idea could be that the reincarnated character has memories of the future of the Boruto world. So they try to prevent certain disasters from happening, like the fall of Konoha. Another could be that they use their modern - day knowledge to revolutionize the ninja technology in the Boruto universe.
One idea could be a crossover with Naruto's past characters. For example, Boruto somehow travels back in time and teams up with a young Naruto to face a new threat that endangers both their timelines. This would create an interesting dynamic between the two generations.
Well, a plot could be about Naruto and Sakura having to train Boruto in a special way that combines their unique abilities. Naruto could teach Boruto about his Rasengan and Sakura about chakra control and medical ninjutsu. This would create a story about Boruto's journey to master these combined skills and how it shapes his character in the Boruto series.
One idea could be a time - travel plot where Boruto and Sarada are sent back to Naruto's era. They could interact with a younger Naruto and help him in some way that changes the future subtly. For example, they might help Naruto with a difficult mission that he barely survived in the original timeline, and this could lead to different relationships in the future.
A possible plot is that Boruto discovers a hidden power within himself that was passed down from Naruto and Hinata combined. This power could put him in a dangerous situation as various factions might want to either control or eliminate him. Or perhaps Boruto has to deal with the pressure of being the son of the Hokage and a powerful Hyuga, and he decides to go on a journey to find his own identity away from his parents' shadows.
In a fanfiction about baby Naruto's birth, a really interesting aspect could be the secrets that were passed down during that time. For example, if there were any special Uzumaki clan traditions related to the birth of a new heir. And what if some of the older ninja in the village, who knew about the Uzumaki clan's power, were already making plans for Naruto's future? Maybe they were thinking about how to train him to be a great asset to the village from the very start.
