Naruto could have an arc of self - discovery. He'd have to find out who he is without his voice and sight. Another character arc could be his friends' journey in understanding and helping him. For instance, Kakashi might train Naruto in new ways to fight. And Naruto might also have an arc of acceptance, coming to terms with his disabilities.
One possible character arc for Naruto is that of adaptation. He starts off struggling with his new conditions but gradually learns to function. His friends also have arcs. Sakura could have an arc of frustration as she tries to find a medical solution but fails at first. Then she could have an arc of perseverance. Sasuke might have an arc of re - evaluating his relationship with Naruto. He realizes that Naruto's situation makes him more complex and worthy of respect.
In this fanfiction, Naruto's character arc could be centered around his transformation. At first, he might be in a state of despair, but then he begins to fight back. He discovers new abilities and strengths. His friends' character arcs would be intertwined. They would have to learn to be more empathetic and creative in their interactions with Naruto. For example, Shikamaru might use his intelligence to come up with new strategies for Naruto to use in battle, which would also be part of his own character growth.
For Naruto, his character arc could start with his intense hatred for Sakura. As the fanfiction progresses, he might start to question his feelings. Maybe he realizes that his hatred was misdirected or based on false assumptions. For Sakura, her arc could be about persevering in her love despite Naruto's hatred. She could grow stronger and more confident in expressing her feelings and trying to change Naruto's view of her.
To handle Naruto's character development, the author could focus on his relationships. Since he can't communicate verbally in the traditional sense, his interactions with others will be different. He might form deeper emotional bonds with those who take the time to understand him. This could lead to his growth as a person. For example, a friendship with Sasuke could develop in a new way where Sasuke has to be more patient and empathetic, and Naruto in turn learns to trust more deeply. Also, Naruto could develop his self - esteem as he overcomes challenges related to his disabilities and proves his worth as a ninja.
One possible plotline could be Naruto using his godlike powers in unique ways to communicate without speaking. Maybe he can project his thoughts or emotions directly into others' minds. Another could be that his muteness is a result of some great sacrifice he made to gain his godlike powers, and the story could revolve around how he overcomes the challenges of being mute while being so powerful.
One plot idea could be Naruto finding unique ways to communicate his ninja skills despite being mute. For example, he might use hand signals in a more complex way than normal. Since he's blind, he could develop an extraordinary sense of hearing to detect enemies. Another idea is that he forms a special bond with an animal that helps him 'see' the world around him, like a seeing - eye hawk or something.
One possible reason could be overusing his special powers like the Rasengan or Sage Mode. These techniques might have some sort of negative impact on his eyes over time. For example, if he doesn't control the chakra flow properly during these powerful moves, it could damage his optic nerves gradually.
One possible character arc for Percy could be a journey from confusion to acceptance. At first, he may be completely bewildered by this new 'heir of Tartarus' status. He might resist it, but as the story progresses, he could come to accept it and find a way to use it for good. Another arc could be a fall - and - redemption arc. He could initially be corrupted by the power of Tartarus and turn against his friends, but then through some self - realization and the help of those who still believe in him, he could be redeemed.
One possible plotline could be Naruto having to find new ways to communicate his ninja skills and strategies without speaking. He might develop a unique sign language that only his closest friends can understand at first. Another plotline could involve Naruto's inner thoughts being more emphasized as he can't verbally express himself. His friends would have to learn to read his body language and expressions more carefully. And perhaps there could be a story arc where Naruto discovers a hidden power that is related to his muteness, like a special chakra that he can only access when he is silent.
Perhaps he makes a deal with a powerful entity. In order to gain some extraordinary power to save the village or his friends, he has to sacrifice his voice. It could also be due to a side - effect of some new jutsu he tries to master. The jutsu could be so powerful that it takes away his ability to speak as a trade - off for the new abilities it gives him.
One storyline could be Naruto gradually losing his sight over time but hiding it because he doesn't want to worry his friends or seem weak. He could struggle with simple tasks like reading scrolls or finding his way around Konoha without making it obvious.
One possible plotline could be that Naruto has been hiding his blindness all along to protect his friends. He might have developed special techniques to compensate for his lack of sight, like relying more on his other senses such as smell and hearing. For example, he could use his sense of smell to detect enemies' movements and positions, similar to how he uses it to find Sasuke in the original series. Another idea is that his blindness is a result of some hidden power or curse, and as the story unfolds, he has to find a way to either overcome it or use it to his advantage.
