In this fanfiction scenario, Sasuke might see Naruto's lost arm as a symbol of Naruto's sacrifice for their relationship or for the greater good. This could make Sasuke more committed to Naruto's cause. He would be more likely to fight alongside Naruto, and they would share a new level of trust. Naruto, on the other hand, might initially be hesitant to rely on Sasuke, but as they face challenges together, they would reaffirm their friendship and partnership.
It could make Sasuke more protective of Naruto. Sasuke has always had a complex relationship with Naruto, and seeing him lose an arm would stir up some deep emotions. He might feel guilty, especially if he was somehow involved in the incident that cost Naruto his arm. This could lead to Sasuke staying closer to Naruto and being more open about his feelings.
With his friends, it might strengthen their bonds. They would be more protective of him and help him in his daily tasks. For example, Sasuke might become more empathetic towards Naruto's situation. His relationship with Hinata could also change. Hinata would be very concerned and would constantly be by his side, offering emotional support.
Well, losing an arm would definitely have a huge impact on his ninja abilities. His ability to perform hand seals would be severely hampered. For example, complex jutsus that require multiple and quick hand seals might become impossible for him to execute. Also, his balance in combat could be affected as he's used to having two arms for movement and defense. He'd probably have to rely more on his legs and other non - arm - related skills.
Maybe he starts to train with one - armed techniques. He could learn from other one - armed ninjas if there are any in the fanfiction world. His friends would also play a big role. They might encourage him to keep going or help him in his training.
In the long run, this confrontation could be a turning point. If they overcome their differences, it could lead to a deeper and more mature relationship. For example, they might start to respect each other's views more and work together more effectively in future adventures.
In the fanfic, Naruto's character could also become more introverted as he copes with the loss of his arm. He might need time alone to come to terms with his new reality. However, this solitude could also give him time to reflect on his life and his ninja path. He may emerge from this period with a new sense of purpose, perhaps focusing more on non - combat aspects of being a ninja, like diplomacy or teaching. This would be a significant shift from his previous more action - oriented self.
His relationships would shift in many ways. With his family, if he has one by that point, they would be deeply concerned and try to help him adjust. His comrades in the Hidden Leaf Village would be more watchful over him. Enemies would likely underestimate him at first, which could be both a danger and an opportunity for Naruto. His relationship with the tailed beasts might also change, as they might be sympathetic towards his new disability and offer different kinds of support or advice.
Maybe he was protecting someone in Wave. He's always the self - sacrificing type, so he could have put himself in harm's way to save a villager or a friend.
It could either strengthen or strain their relationship. If Naruto gains power from the Shinju fruit and uses it for good, Sasuke might respect him more. However, if Naruto starts to change in a way that Sasuke doesn't like, it could cause friction. For example, if Naruto becomes too overconfident with his new power, Sasuke might see it as a negative change. Or, if Naruto's new power makes him a target, Sasuke could feel the need to protect him, which would bring them closer together in a different way than before.
Losing his real arm is a major turning point for Bucky. He was used to his body being a weapon, and now a part of that weapon is gone. This forces him to confront his own mortality and limitations. He might become more empathetic towards others who have disabilities or who have suffered loss. It also gives the writers of the fanfic a chance to explore his resilience. He can either let this loss break him or use it as a springboard to become a more complex and well - rounded character.
In the fanfic, if Naruto kills the Sound 4, it could make Sasuke more competitive. He might see Naruto as having achieved a level of ruthlessness that he himself desires. Or, Sasuke could be disappointed in Naruto for resorting to killing. Their relationship would be full of tension as Sasuke tries to figure out where he stands in relation to a Naruto who has killed, and Naruto might struggle with Sasuke's reaction to his actions.
