For one, it would create a great deal of grief among the other characters in the fanfiction. His friends like Sasuke, Sakura, and Kakashi would be devastated. The readers would feel their pain. It also stirs up emotions like admiration for Naruto's courage. He's giving up his life to stop a great evil, which is a very noble act. And there might be a sense of anger too, towards the situation that led to his death.
The people closest to Naruto, like Hinata, would be completely devastated. She would be by his side, crying and feeling like her world is falling apart. The thought of losing Naruto, the man she loves, would be almost too much to bear.
For Natsu, it would be devastating. Happy has been his constant companion since they were young. Natsu would likely be filled with rage and grief, which could potentially lead him to seek revenge against whoever or whatever caused Happy's death.
For Sakura, she would be extremely worried. Naruto is not just a friend but also someone she has grown up with and has deep emotional ties to. She might feel guilty if she can't find a way to cure him quickly. Sasuke, on the other hand, would be conflicted. He has a complex relationship with Naruto. His pride might not let him show too much concern at first, but deep down, he would be very worried. His emotions could range from fear of losing Naruto to the realization of how much Naruto means to him. And for the other villagers, they might feel a sense of panic. Naruto has become a symbol of hope for them, and his sickness could make them fear for the future of the village.
On Tsunade's side, she would also be conflicted. Even if she has reasons for her actions, she has a bond with Naruto. She might feel guilt and regret, especially if she realizes she was misled. The village as a whole would be in turmoil. Naruto has many friends and supporters, and if they believe he was wrongly betrayed, it could lead to a split in the village, with some siding with Naruto and others with Tsunade.
The emotional impact could be profound. Iruka has always been an important figure in Naruto's life. If he's holding a dying Naruto, it would be a heart - wrenching moment filled with grief, regret, and a sense of helplessness. It would also show the deep bond between them, perhaps making readers reflect on all the times they've shared together throughout the series.
There would be a lot of anger. Naruto might be angry at his parents for leaving him, and this anger could fuel his determination in some ways. For example, he could strive to become a great ninja just to prove that he didn't need them. But it could also cause problems in his relationships, as he might lash out when reminded of his abandonment.
Show Naruto's fear and regret. For example, he might regret not spending more time with his family or not achieving all his goals for the village. His fear of leaving his loved ones behind, especially his children, can be a very emotional aspect.
Yes, it can be considered a somewhat common plot twist in fanfiction. Many fanfiction writers like to explore extreme and unexpected scenarios. Naruto sacrificing himself to kill Madara shows a great deal of selflessness and heroism. It also adds a tragic and bittersweet element to the story, which can be very appealing to readers who enjoy complex and emotional narratives.
The emotional impact would be far - reaching. The entire Hidden Leaf Village would mourn Naruto. He was the one who was supposed to bring change and hope. His friends like Shikamaru and Choji would feel a deep sense of sadness. They would question the fairness of the ninja world where such a selfless person like Naruto could die so young. Haku, in particular, would be haunted by Naruto's death. He might isolate himself at first, struggling with the fact that someone sacrificed themselves for him.
Naruto would likely experience a range of emotions. He could be in denial at first, not wanting to believe that this disease could end his life. Then there would be sadness, thinking about all the things he might not be able to achieve. He'd also feel guilty for making his friends worry. And there would be moments of anger, directed at the unfairness of getting such a disease.
