Well, it could be about Hiruzen teaching Naruto all kinds of ninja skills from a young age. Maybe he also imparts wisdom and values to Naruto, which makes Naruto grow into a very different ninja compared to the original story. For example, Naruto might be more composed and less of a troublemaker in the village at first because of Hiruzen's strict yet loving upbringing.
Perhaps Hiruzen is being influenced by some dark force or a hidden group within the village. They convince him that Naruto, with the Nine - Tails inside him, is too dangerous to be left unchecked. So, Hiruzen, in a moment of weakness, decides to betray Naruto. He could secretly arrange for Naruto to be sent on dangerous missions alone with the intention of getting him killed. Naruto, being oblivious to this at first, later realizes what's going on and has to fight not only against external enemies but also against the betrayal of his own village leader.
In this fanfiction, perhaps Hiruzen realizes Naruto's potential much earlier and decides to train him privately. He might take Naruto on secret missions to build his experience and confidence. This would not only strengthen Naruto's skills but also their bond, which could have a huge impact on the village's future.
The plot might involve Naruto learning about the history and politics of the village from Hiruzen. Since Hiruzen has a wealth of knowledge and experience, he could be guiding Naruto on how to be a great leader in the future, not just a powerful ninja.
One possible plot is that Hiruzen discovers a plot against Naruto by some anti - Uzumaki forces. He then uses his combat skills and his network of spies to stop the threat before it reaches Naruto. He might also place some of his most trusted shinobi to guard Naruto at all times.
Naruto might be more knowledgeable about the history and politics of the village. Hiruzen, being the Hokage, would surely educate Naruto on such matters. This would make Naruto more diplomatic and better able to handle complex village - related issues. He would also be more respectful of traditions and the hierarchy within the village, having been raised by the village's leader.
In the fanfic, Hiruzen could train Naruto in stealth and intelligence - gathering techniques. Naruto is often portrayed as a straightforward fighter in the original series. But with Hiruzen's training, he could become a more well - rounded ninja. He might learn how to infiltrate enemy bases, gather crucial information, and use that knowledge to outwit his opponents. This would add a new dimension to Naruto's character and his abilities in battles.
The plot could involve Naruto and Hiruzen competing for the position of Hokage at the same age. Naruto, with his strong will and determination, would try to prove himself worthy. He might have different friends and allies in this version. For instance, he could team up with some of the older shinobi who were Hiruzen's contemporaries. Their rivalry could lead to new and exciting battles and political intrigue within the village.
Well, a plot twist could be that since Naruto is Hiruzen's son, the Akatsuki targets him differently. Instead of going after the Nine - Tails inside him in the usual way, they might try to use his relationship with Hiruzen against him. They could try to blackmail Hiruzen into making certain concessions for the safety of his son. Also, Naruto's training might be more intense and different. He might be taught more about the political side of being a ninja by Hiruzen himself, which changes his perspective on the ninja world.
One possible plot could be that Naruto grows up with unique ninja skills taught by the kunoichi. He might have a different view on relationships and teamwork compared to canon. For example, he could be more in tune with female perspectives.
Well, it could be that Naruto is found by friendly ghosts as a baby. They might teach him unique skills that are different from the normal ninja arts in the Naruto world. Maybe they use their ghostly powers to help him train, like making him run through spectral obstacles.
