One plot idea could be that Sakura, in her pursuit of medical ninjutsu knowledge, discovers some ancient scrolls that were once in Hiruzen's possession. She then tries to seek out the secrets within them with the help of Hiruzen's spirit or memories that somehow still linger. This could lead to her developing a new form of medical ninjutsu that combines old and new knowledge.
The fanfiction could start with Sakura being curious about the ninjutsu of the past. She seeks out knowledge about Hiruzen's skills. As she delves deeper, she realizes the complexity and versatility of his ninjutsu. Meanwhile, Hiruzen's spirit or memories could be used to observe Sakura's skills. This exploration could lead to a new form of training for Sakura, where she incorporates some of Hiruzen's techniques into her own style, and in turn, the story could show how modern ninjutsu can be enhanced by the wisdom of the past.
Yes, in certain fanfictions Naruto hates Hiruzen Sarutobi. Fanfiction often takes the original characters and storylines and twists them. Maybe the writer of such a fanfiction thought that Hiruzen's actions, like not fully protecting Naruto when he was a child, could lead to Naruto having negative feelings towards him in this alternate take on the story.
One possible fanfiction could be about an OC (original character) who is a student of Hiruzen Sarutobi. This OC has always heard tales of Minato Namikaze's heroics. The story could involve the OC getting into a difficult situation, perhaps a dangerous mission, and drawing inspiration from the skills and courage of Minato. Hiruzen, as the wise teacher, could guide the OC in learning from Minato's example. For example, the OC might be struggling with a new jutsu, and Hiruzen tells them how Minato mastered a similar one with his determination and innovation.
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.
One common theme is friendship. Given their different positions in the village, a story could be built around how they become friends. Another theme could be protection. Since Kushina is a jinchuriki, Hiruzen might be involved in protecting her from those who would seek to use her power for evil.
One reason could be the way Hiruzen treated Naruto as a child. In the original, Naruto was kind of an outcast, and if in fanfiction, Naruto blames Hiruzen for not doing more to prevent that, he could hate him. Another reason might be related to Hiruzen's decisions regarding the Uchiha clan. If Naruto in fanfiction feels that Hiruzen's actions led to bad consequences for the village and his friends, he might develop hatred.
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.
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.
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.
