Maybe Naruto is put in a situation where he feels that Hiruzen's way of handling things is the best option. For instance, if there is a major crisis in the village that requires a more traditional and experienced approach, Naruto might choose to act like Hiruzen. Also, he could be influenced by the stories he has heard about Hiruzen and wants to fill his shoes in a way.
Perhaps in this fanfiction, Naruto has some sort of special power or transformation that he unlocks just in time to face Orochimaru. It could be related to his Nine - Tails chakra in a new and unique way. He uses this power to break through Orochimaru's defenses and save Hiruzen. Naruto might also use his knowledge of Orochimaru's weaknesses that he has learned either from Jiraiya or from his own past encounters with Orochimaru's minions.
I'm not entirely sure specifically as it depends on the individual work. But generally, it might involve creating fictional stories centered around characters named Naruko and Hiruzen. It could explore their relationship, adventures they might have together, or different scenarios in a made - up universe.
There's a fanfiction I read once that explored how Kushina's fiery personality and Hiruzen's wisdom could combine to solve a major crisis in the village. It was really interesting to see how the author developed their characters and the unique bond that formed between them.
One challenge is the time gap between their eras. Sakura is from a more modern time in the Naruto series, while Hiruzen is from an earlier generation. So, it can be difficult to create a believable scenario where they interact in a way that doesn't seem forced.
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.
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.
Perhaps there are some shinobi within the village who are jealous of Naruto's potential. They might try to harm Naruto in secret, and Hiruzen has to be vigilant against them. These shinobi could be from clans that have rivalries with the Uzumaki or those who just don't want a new powerful force emerging in the village.
One common theme is the passing of knowledge. Hiruzen, with his years of experience, can pass on wisdom to Kushina. Another is the protection of the village. They both care deeply about the Hidden Leaf and stories often revolve around them working together to safeguard it.
Yes, there are quite a few. Some fanfictions might focus on their interactions within the Hidden Leaf Village. For example, they could be involved in a joint mission where Hiruzen, as the experienced Hokage, imparts some of his wisdom to Kushina. This could lead to a great story of mentorship and friendship.
