In a fanfic, perhaps there is an alternate universe where Danzo was always in line to be Hokage and Naruto was trained by him from the start. This would completely change Naruto's character development as he would be influenced by Danzo's more ruthless and secretive ways. However, over time, Naruto could still strive to bring a positive change to the village even under Danzo's tutelage.
A possible fanfic could explore what would have happened if Danzo had a change of heart before becoming Hokage. He could start to see the error of his ways and try to make amends with the village and Naruto. This could lead to a story of redemption and a new era of leadership in Konoha that is more inclusive and less about power - grabbing.
One idea could be a fanfic where Danzo actually manages to become Hokage through some underhanded means. Then Naruto has to find a way to expose his true nature and restore the rightful leadership to the village. Maybe he teams up with some of the other shinobi who were also suspicious of Danzo's actions all along.
One possible reason could be that some elders in the village still have doubts about his past. For example, his connection with the Nine - Tails. They might fear that this could lead to instability in the village. Another reason could be political intrigue. There might be other powerful clans or individuals who want the position for themselves and manipulate things behind the scenes to deny Naruto.
In a fanfic, Danzo's Hokage - like ambitions could be explored through his relationship with the other villages. He might be more aggressive in foreign relations, which could draw the ire of other ninja villages. Naruto, being the protagonist who wants peace, would then be in a difficult position. He would have to either oppose Danzo's warmongering or find a way to make him see the benefits of peace.
He might be very disappointed at first. Naruto had always dreamed of becoming Hokage, so it would be a huge blow. But he could also use this as motivation to prove himself even more. He would likely go on some self - improvement journey, training harder and showing the village that they made a mistake.
Another aspect to explore in the fanfic is Naruto Senju's relationship with the other villages. Given his Senju heritage, there might be different expectations and tensions. He could work towards a more equal - footed relationship with other villages, instead of the traditional power dynamics. This would involve a lot of diplomatic meetings and negotiations, which could be full of drama and intrigue.
A really interesting plot could be Naruto traveling back in time to the era before he was born. He could meet his parents and other important figures in the village's history. This would give him a chance to understand the roots of the village better and also learn some new jutsu or strategies that he could bring back to his own time to make the Hidden Leaf even stronger as a Hokage.
One idea could be a story where Naruto and Haku team up on a special mission. They could start off not trusting each other much, but as the mission progresses, they come to respect and rely on one another's skills. For example, Naruto's brute strength combined with Haku's stealth and water jutsu could make for an interesting dynamic in overcoming the mission's obstacles.
One idea could be a fanfic where the 7th Hokage, Naruto, has to face a new and powerful enemy from a hidden land that was previously unknown. This enemy has a unique jutsu that can nullify Naruto's chakra. Another idea is a story about Naruto's daily life as Hokage, dealing with the paperwork while also trying to find time for his family.
One idea could be a story about Kushina and Mikoto being friends when they were young and how their friendship influenced Naruto's life. For example, they could have made a pact to always look out for each other's children. Kushina might have told Mikoto some special Uzumaki techniques that Mikoto then passed on to Sasuke in a way. Another idea is a time - travel fanfic where Naruto goes back in time and meets his mother Kushina and Mikoto when they were in their prime. He could learn a lot about the past of the village and his family from them directly.
Perhaps a fanfic about a special training session. Kushina and Mikoto decide to train Naruto together. Kushina teaches him some unique Uzumaki jutsus, while Mikoto imparts some of the Uchiha's wisdom and combat skills. Through this training, Naruto not only becomes stronger but also forms a deep bond with the memories of his mother and Sasuke's family.
A fanfic where Tsunade and Kushina train Naruto in a new and unique form of ninjutsu. They take him to a secret location and over the course of the story, Naruto masters this new skill. Along the way, they share stories and experiences, strengthening their bond as comrades and friends.
