In some fanfics, Naruto might use his new and powerful jutsu that he has mastered over time. Maybe he combines his Sage Mode with the power of the Nine - Tails in a unique way that Orochimaru can't counter. For example, he could use the Nine - Tails' chakra to enhance the range and power of his Sage Mode attacks, and then catch Orochimaru off - guard.
Well, it could be that Naruto has some sort of unexpected weapon or power - up. Perhaps he discovers a hidden ability within himself, like a special kekkei genkai that is specifically effective against Orochimaru's jutsu. He could then use this newfound power to quickly and decisively defeat Orochimaru.
In certain fanfic scenarios, Naruto might get some help from his friends or allies in an unforeseen way. For instance, Sakura could use her medical ninjutsu to enhance Naruto's physical abilities temporarily, and then Naruto uses this boost to overpower Orochimaru. Also, Shikamaru could come up with a brilliant strategy that Naruto executes perfectly to take down Orochimaru.
In this kind of fanfiction, Naruto might have used his new and powerful jutsu that he developed secretly. Maybe it was a super - enhanced Rasengan with some special chakra nature added to it, which was strong enough to overpower Orochimaru.
Well, in some versions, Naruto might use his new and improved Rasengan techniques. He could have combined it with his Sage Mode powers to overpower Orochimaru. Maybe he also uses his quick thinking and the element of surprise, since Orochimaru is always so full of his own schemes.
One consequence could be a shift in the power balance among the ninja villages. Since Orochimaru was a powerful and feared figure, his death might cause some chaos as his former allies or subordinates try to either avenge him or claim his resources. For example, some of his secret labs and experiments might be up for grabs, leading to potential conflicts.
Well, in some fanfictions, Orochimaru might use some forbidden jutsu. He could have combined his knowledge of resurrection techniques with some unique chakra sources. Maybe he found a way to reverse the death process by using the power of the snakes he has a connection with. For example, he could have used the regenerative abilities of the snakes' chakra to bring Naruto back to life.
It depends on the specific fanfic. Some authors might come up with this plot twist to explore different character motivations and conflicts. In others, it might not be the case at all.
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 a fanfic where Orochimaru kills Naruto, the plot would take a very different direction. Naruto was the Jinchuriki of the Nine - Tails, and his death would mean the Nine - Tails' power is lost. Orochimaru might try to take over Konoha or use Naruto's death to gain some other advantage. The other ninja villages might see Konoha as weak and attack. His friends would have to deal with the grief and might turn to different paths, some perhaps darker in their search for meaning after such a loss.
It could have a major impact on the power balance. With Orochimaru gone, many of his secret experiments and knowledge could be lost or fall into the wrong hands. Naruto, being 'godlike', might be seen as the new power to keep in check. His friends and allies might start to distance themselves out of fear or respect for his new power level. The Akatsuki, too, would need to re - evaluate their plans as one of their potential allies or threats (depending on Orochimaru's relationship with them at the time) is no longer in the picture.
Perhaps Naruto teams up with some unexpected allies. For example, he could convince some of Orochimaru's former henchmen to turn against him. These henchmen could provide valuable information about Orochimaru's lair and the security measures in place. Using this information, Naruto can plan a strategic rescue and save Hinata.
Naruto might resist through his strong willpower. He has always been determined, and this would not change even under torture. He could keep thinking about his friends in the Leaf Village and his goal of becoming Hokage, which gives him the strength to endure.
