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.
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.
One possible aspect of Finn losing his arm in fanfiction could be how it changes his physical capabilities. He might have to adapt his fighting style, perhaps relying more on his legs or using his remaining arm in more creative ways. For example, he could learn to use his sword one - handed in a whole new way that surprises his enemies.
In some fanfictions where Allen loses his arm, it could lead to a whole new set of character developments. He might become more dependent on his comrades at first. For example, Lenalee could be there to help him with daily tasks that require two hands. This could strengthen their bond. Also, it might make Allen more determined to fight against the Earl. Losing his arm could be seen as a sacrifice that fuels his hatred for the dark forces. He could start training to use his other abilities more effectively, like his Innocence in a different way that doesn't rely so much on his physical arm.
In the context of the fanfic, it could also impact his relationships. His friends might be overly protective, which Naruto may not like. Or, he could inspire others with his determination to keep going despite his injury. It might also change how he is perceived in the ninja world. Some may see him as weakened, while others could view him as even more of a hero for his ability to persevere.
Well, he might face difficulties in combat. Without his arm, his fighting style would have to change drastically. He may rely more on his ninjutsu and less on physical attacks. Also, his daily life activities like eating or holding things would be a struggle.
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.
Losing his arm would be a huge blow to Harry. His friends' reactions would be mixed. Hermione would be practical, trying to find magical solutions or aids for Harry. Ron would be more emotional, showing his support through his presence. Some of his other friends might be a bit afraid or unsure at first. But over time, they would all come to accept Harry as he is now and their relationships would be based on a new level of understanding and support.
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.
In this fanfiction, once Natsu loses his arm, the story progresses in several ways. At first, there's shock and sadness among his friends and the guild. Natsu has to come to terms with his new reality. He starts to train differently, focusing more on his magic control. There could be a sub - plot where an enemy tries to take advantage of his weakened state. But Natsu, with the help of his friends, overcomes these challenges. He may also meet some new characters who have knowledge about arm - restoration magic or something similar. As he embarks on this journey, the story could explore themes of perseverance, friendship, and the power of the human (or in this case, dragon - slayer) spirit.
