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.
Their character development could also be centered around their discovery of new abilities. Maybe they initially think their blindness is a hindrance, but as they explore their ninja skills further, they find that they can do things no one else can, like using sound waves in a more advanced way to navigate and attack, which changes their perception of themselves and their role in the Anbu.
For Naruto in Anbu, you could start with his initial brashness still showing but slowly being tempered by the strict Anbu code. As he interacts with Yugao, he starts to see things from a different perspective. Yugao, on the other hand, could start as a reserved and focused ninja. When she meets Naruto, his energy starts to break down her walls. You can show their development through their conversations and how they react to different situations together.
When writing their character development, consider the challenges they face. Naruto in the Anbu has a dark side to his work that Ino may not understand at first. Have Ino be curious and try to understand Naruto's world, which in turn makes Naruto more willing to open up. For Ino, have her face some self - doubt in her ninja abilities, and Naruto's belief in her can boost her confidence. Their relationship should be a two - way street where they both evolve based on their interactions and the situations they encounter together.
I would recommend 'Anbu Naruto: The Path of Growth'. It really focuses on how Naruto changes and matures as an Anbu member. His relationships with other Anbu agents are explored in depth, and you can see his values evolving as he faces different situations in the Anbu world.
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 may learn to suppress his emotions better in ANBU fanfictions. This would be a big step for him as he is known for wearing his heart on his sleeve. Iruka, on the other hand, could become more strategic. He might start to think more like a true ANBU operative, planning several steps ahead. This would change his character from just a teacher to a more complex and capable ninja. Also, their bond could strengthen in the face of the more dangerous and secretive ANBU world as they rely on each other more.
One idea could be that the blind Anbu has a special ability to sense chakra in a unique way. For example, they can detect the slightest change in an enemy's chakra, even if they can't see them physically. This gives them an edge in battle.
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.
His character could become more jaded. In the ANBU, Naruto would have seen a lot of the darker side of the ninja world. He might be less naive and more calculating. For example, he would be more hesitant to trust people immediately like he used to.
Naruto's character often develops a more serious and stealthy side. He has to learn to keep his emotions in check, which is a big change from his usually exuberant self. For example, he might not be as quick to shout out his goals or feelings.
Well, in a fanfiction where Naruto joins ANBU, his training would intensify. He'd be trained by some of the toughest ANBU veterans. His skills in combat would become more refined as he'd learn to use weapons like kunai and shuriken with more precision. He may also develop new jutsu that are more suitable for covert operations. His growth as a ninja would be different from the regular path, focusing more on secrecy and assassination if required.
