It might start a new arc in the fanfiction. Naruto's self - experiment could attract the attention of powerful enemies or allies. For instance, if he gained some new and dangerous power, some villains might see him as a threat and target him. On the other hand, some secret organizations might want to recruit him. This would lead to new adventures, battles, and alliances for Naruto.
The plot could also focus on Naruto's internal struggle. As he experiments on himself, he has to deal with the physical and mental changes. He might question his identity and purpose. This self - reflection could make him reevaluate his relationships with his friends, his village, and his ninja way. And as he overcomes these challenges, he could emerge as an even stronger and more mature character in the fanfiction.
The plot could take a dark turn. Naruto's friends might become worried about him and try to stop his self - experimentation. This could lead to a conflict between Naruto's desire for power and his friends' concern for his well - being.
The story could start with Naruto being in a strange place and suddenly seeing his other self. Then they would start to exchange words. It might develop into a battle at first as Naruto tries to figure out if this other self is a threat.
His character could develop in a darker direction. The torture and manipulation from Orochimaru's experiments could make him question his values. However, it could also strengthen his resolve to protect his friends and the village. He may start to see the world in a more complex way, understanding that there are greater evils out there. And his newfound powers from the experiments could give him a sense of responsibility that he didn't have before.
His character could develop in several ways. First, he would become more independent. He'd be forced to make all decisions on his own, which could lead to him growing up faster. Second, he might become more solitary in nature. Since he doesn't have a team to bond with, he could focus more on his own goals and desires. However, this could also make him more empathetic towards others who are alone. Third, his ninja skills would likely improve at a different pace. Without teammates to spar with regularly, he might focus more on solo training techniques and develop unique skills that are tailored to his individual fighting style.
Well, he could gain some new and unexpected powers. Maybe he discovers a way to enhance his chakra control to an extreme level, allowing him to perform jutsus with much greater efficiency and power.
Well, it's possible that in the fanfiction, Naruto is experimented on as part of a desperate attempt to save the village. There could be a new threat on the horizon, and the village elders or some ninja with knowledge of forbidden techniques believe that by experimenting on Naruto, who has shown great resilience, they can find a solution. They might be trying to turn him into a weapon or a shield for the village, which would put Naruto in a really tough situation both physically and morally.
This is a very dark and unexpected plot. One possibility could be that Naruto is burdened by some extreme situation related to Hinata. Maybe he feels responsible for her getting into a great danger or a situation where her life is ruined, and his sense of guilt overpowers him, leading to this tragic end.
At first, Naruto would probably be excited. He's always eager to get stronger, so he might see this as an opportunity. He'd trust Tsunade because she's the Hokage and a respected medical ninja. But if the experiments got too painful or started to seem strange, he'd start to question things. He might try to talk to Tsunade about it, but in his Naruto - like way, still be respectful.
The plot could start with Naruto suddenly getting a high fever. His friends notice his strange behavior like being more sluggish than usual. Then, they take him to the hospital. As he's recovering, he could start to remember some forgotten memories related to his parents or some past traumas.
The plot could start with Naruto isolating himself. He would avoid his friends and stay away from the village. His friends would notice this change and try to reach out to him. But Naruto, being scared, would react badly. This would create a lot of confusion and worry among his friends. Then, as the story progresses, they would try to find out the reason behind his fear.
The plot could start with Naruto isolating himself from the village. He might go on a journey alone, avoiding any contact with humans. Along the way, he could encounter some non - human creatures who show him kindness, which makes him question his hatred.
