Well, perhaps in the fanfiction, Naruto is reborn with Hashirama's memories. This would give him a huge advantage in understanding the history of the ninja world and the secrets of the Senju clan. He could use this knowledge to reform the Hidden Leaf, making it even stronger. He might also be able to prevent some of the tragedies that happened in the past, like the Uchiha massacre, by using Hashirama's diplomatic skills and understanding of the clans.
A possible plot could be that both Naruto and Hashirama are reborn simultaneously. They might team up to face a new, powerful enemy that even the combined forces of the Hidden Leaf couldn't handle before. Since Naruto has his Uzumaki chakra and Hashirama has his Senju power, together they could create new and powerful jutsu. For example, Naruto's chakra could enhance Hashirama's Wood Style to cover larger areas or be more durable.
An interesting plot could be that Naruto, as Hashirama's nephew, has a natural affinity for wood - style jutsu. However, he struggles to control it at first. This leads him on a quest to find a way to master it, all while dealing with the new - found attention from both friends and foes. He could also uncover secrets about Hashirama's life that were previously unknown, which in turn helps him in his journey to protect the village.
One idea could be a time - travel plot where Naruto is sent back in time to the era of Hashirama and Madara. He could try to prevent their feud from escalating and change the course of ninja history. This would involve him using his modern - day knowledge and skills in a very different context.
One idea could be a story where Madara and Hashirama are reborn in the modern ninja world and have to navigate the new technologies while still having their old grudges and loyalties. They might initially be confused but then slowly adapt and perhaps even find a way to resolve their age - old differences.
One idea could be a time - travel plot where Naruto gets sent back in time and meets Hashirama. They could team up to face a new, unknown threat that was secretly brewing during Hashirama's time. Another could be a story where Naruto inherits some of Hashirama's unique abilities through a special jutsu or curse and has to learn to control them.
One idea could be Naruto traveling back in time and meeting Hashirama. They could team up to face a new, powerful enemy that threatens the very foundation of the ninja world. Naruto's modern techniques combined with Hashirama's wood - style jutsu would make for some epic battles.
Maybe the son discovers an ancient scroll left by Hashirama that contains long - lost jutsu. This sets him on a journey to master these jutsu while also facing the challenges of those who want the scroll for their own malicious purposes. He could have to team up with Naruto and his friends to protect the scroll and the village.
One plot idea could be that Fem Naruto, with her unique charm and determination, teams up with Hashirama in a time - travel scenario. They go back to the founding days of the village to prevent a great disaster that was previously hidden in history. Another could be a story where Fem Naruto discovers she has a special connection to Hashirama's chakra, which leads to her unlocking new powers and having to deal with the responsibilities that come with it.
One idea could be that Hashirama's ghost appears to Naruto during a crucial battle. He imparts some long - forgotten jutsu or strategy that was unique to the Senju clan. This could give Naruto an edge in the fight and also help him understand more about the history of the village.
One idea could be a story where Naruto and Hashirama meet in a time - travel scenario. Naruto gets to learn directly from Hashirama about his wood - style jutsu and his vision for the village.
The power combination would be interesting. Naruto already has his own set of strong abilities, and if he was Hashirama reborn, he might gain access to Hashirama's wood - style jutsu, creating a whole new range of combat possibilities.
