Perhaps Naruto discovers a prophecy that Hiruzen will be in danger. So, he starts to train extra hard to be able to face whatever threat is coming. When the time comes, he uses his speed, which he has enhanced through rigorous training, to reach Hiruzen before the enemy can land a final blow.
One possible scenario in a 'Naruto Saves Hiruzen' fanfic could be that Naruto uses his newfound powers. Maybe he has mastered a new jutsu that allows him to turn back time briefly. He then uses this power to go back to the moment when Hiruzen is in danger. Naruto's quick thinking and his never - give - up attitude would be highlighted in such a fanfic.
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.
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 key event could be Naruto's discovery of Orochimaru's plan to harm Hiruzen. This might prompt him to take immediate action.
Well, it could be that Naruto discovers a new and powerful enemy that threatens the entire world. Maybe an ancient evil has been awakened. Naruto, with his unwavering determination and his powerful jutsu, would then embark on a journey to gather allies from all the hidden villages. He might have to overcome his own limitations and learn new skills along the way to be able to face this great threat. In the end, through his sheer willpower and the bonds he has with his friends, he defeats the enemy and saves the world once again.
Well, in a Naruto saves Karin fanfic, perhaps Karin is trapped in a collapsing cave due to some sort of powerful enemy's attack. Naruto, with his super - speed and sensing abilities, locates her. He then uses his shadow clones to clear the rubble and rescue Karin. This not only shows Naruto's physical strength but also his determination to save lives.
In a 'naruto adopted by hiruzen fanfiction', the plot could involve Naruto having a closer bond with the older generation of shinobi. Hiruzen would surely introduce Naruto to his trusted comrades. Naruto could learn unique jutsu from them. Also, his growth as a ninja would be different. Instead of seeking attention through pranks, he might focus more on living up to Hiruzen's name. His relationship with Sasuke could also be affected. Maybe they would become rivals in a more positive way, with Naruto having a stronger sense of family and purpose because of Hiruzen's influence.
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.
