Naruto's survival during years of torture in a fanfic could be attributed to multiple factors. Firstly, his Uzumaki heritage gives him strong life - force and stamina. This could help him withstand the physical toll of torture. Secondly, his positive attitude and his ability to find hope in the darkest situations would prevent him from completely breaking down. He might also form an unexpected bond with someone in the place where he is being tortured, and that person could secretly help him by providing food or medical aid at times, which would contribute to his long - term survival.
One way Naruto could survive is by using his Jinchuriki powers. Even in a tortured state, he might be able to draw on the power of the Nine - Tails to heal himself or resist some of the more severe forms of torture. Also, his training with Jiraiya and others has made him physically and mentally tough. He could use the skills he learned, like the Rasengan, in a defensive way if the torturers get too close. His memories of his friends and the promises he made to them would act as a psychological shield against the continuous pain.
Surviving a blizzard is no easy feat for them. Naruto, with his vast chakra reserves, could continuously emit a warm chakra aura around them. Sasuke, on the other hand, would use his intelligence and combat skills. He could hunt small animals for food if necessary. For shelter, they could combine Naruto's earth - style jutsu skills (if he has learned some) and Sasuke's ability to manipulate objects with his chakra. They would also need to keep their spirits up, and their bond as comrades would be crucial in this situation. They could share stories and memories to pass the time and keep their minds off the cold and danger.
He could survive through his strong will and Occlumency skills. By blocking Voldemort from fully penetrating his mind, he can keep his most important secrets safe and hold on to his sanity, which is crucial for survival.
Naruto could use his shadow clones. He could create multiple clones while being tortured. The clones could then create a distraction, allowing Naruto to break free from his restraints. For example, the clones could start a fight among the captors, or they could cause an explosion.
Naruto could develop into a more vengeful character at first. The continuous torture by the villagers might make him angry and want to get back at them. But as the story progresses, he might realize that revenge is not the answer and instead focus on making the village a better place for everyone, including himself.
The fanfiction could explore the backstory of why the villagers torture Naruto. It could be that some evil influence, like a hidden group within the village or a curse, is making them act this way. Naruto, being the strong - willed person he is, might try to uncover this mystery. He would use his detective skills, similar to when he solved various missions. As he gets closer to the truth, the torture might intensify. But Naruto's resolve would not break. He could also find unexpected allies, perhaps some of the older ninja who remember a time before the village turned against Naruto, and they would help him fight against the forces that are causing this unjust treatment.
In a fanfic, Naruto could be captured by a hidden organization that opposes the Hidden Leaf Village. They might torture him to find out the village's secrets. For example, they could be interested in the location of the Hokage's secret vault or the techniques taught only in the Leaf. Naruto, being strong - willed, would resist as much as he can, but the continuous torture would gradually wear him down.
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.
No, it's not that common. Most fanfics tend to focus on more positive aspects like romance, friendship, or adventure. 'Being tortured fanfic' is a rather niche and often more extreme form of fan - created writing.
One possible plot could be that Naruto is captured by a powerful and sadistic enemy. This enemy might use various forms of torture to try and break Naruto's spirit, perhaps to extract information about Konoha. Another plot could involve Naruto being tortured as a result of a false accusation within his own village, and he has to endure years of this while trying to prove his innocence.
It makes Naruto more complex. Instead of just being the energetic and determined ninja we know, he has a darker side. His tortured past can add depth to his character, making him more relatable as he battles with things like self - doubt and fear.
