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.
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.
In a Naruto and Kamen Rider bloodline fanfiction, character development can be centered around the moral implications of their powers. A character with this unique bloodline might have powers that are very destructive. At first, they might be tempted to use these powers without restraint. But as they witness the consequences of their actions, they start to develop a sense of responsibility. They could also look at the values of both Naruto and Kamen Rider universes, like Naruto's belief in protecting friends and Kamen Rider's fight for justice, and use these to guide their character growth.
For Naruto, his neglected past can be the driving force for his growth in the fanfiction. In the Code Geass world, he could start as a lost soul but gradually learn from the experiences there. For example, seeing how Lelouch manipulates the situation, Naruto might start to think more strategically about his actions. His character development could be about becoming more than just a powerful ninja but also a smart leader.
The character could start off being underestimated by others in the Anbu because of their blindness. But as they face various challenges and succeed, they gain respect. For instance, in a mission where they have to infiltrate an enemy base, they use their blindness to their advantage by being less detectable in the dark.
Naruto would become more vulnerable. He has always been this strong and energetic character. But going blind would make him rely more on his other senses and the help of his friends. This could lead to a change in his self - confidence as he has to adapt to his new situation.
In this type of fanfiction, character development is often centered around the alpha - omega dynamic. For Itachi, his alpha status might make him more protective or possessive, and he has to learn to balance these instincts with Naruto's need for freedom as an omega. Naruto, on the other hand, may develop a stronger sense of self - worth and confidence as he navigates his relationship with Itachi. His omega nature can also bring out his nurturing side more, which is a new aspect of his character.
In these fanfictions, their character development is intertwined. Naruto's positive attitude can influence Sakura to be more optimistic. And Sakura's intelligence can help Naruto make better decisions. For instance, if they travel to a time when they are still genin, Sakura can guide Naruto in his training, and Naruto can inspire Sakura to be braver in battles, which is different from their original development in the main series.
In these fanfictions, character development can also be seen in how Naruto and Sasuke handle the external pressures related to their marriage. Naruto, being the more positive one, could inspire Sasuke to face the world with a more optimistic attitude. And Sasuke's determination could rub off on Naruto, making him more focused. Their individual growth is intertwined with their relationship growth. For instance, they might start to train together more often, sharing their skills and knowledge, which not only improves their ninja abilities but also deepens their bond.
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.
For character development, the mute OC might struggle with feelings of isolation at first. But as the story progresses, they could form deep bonds with other characters who learn to understand them in unique ways. For example, a character might be able to sense their emotions, leading to a really heartwarming friendship.
