Naruto's personality would see a significant shift. Being an Anbu captain means dealing with dangerous and often morally gray situations. He would become more cynical to an extent. He'd still have his optimistic side deep down, but on the surface, he'd be more guarded. His sense of humor would probably be more subdued as well. He'd be more focused on analyzing situations and people, looking for potential threats or allies. His leadership would be more authoritative, but also more understanding of the unique challenges his team members face, as he himself has changed to fit the Anbu role.
If Naruto were an Anbu captain, he'd likely be more reserved. He'd have to keep his emotions in check, which is different from his usual open - hearted self. He might not be as quick to jump into action without thinking, as the Anbu operate more stealthily.
He'd likely become more secretive. Naruto is usually very open, but as an ANBU captain, he'd have to hold things back. For example, he couldn't share details about his missions with his normal friends.
He would likely become more withdrawn. Naruto is usually so open and exuberant, but heartbreak could make him close off. In ANBU, he might be quieter, more focused on the mission at hand. He'd still have his determination, but it would be a more solemn determination. His sense of humor might also disappear for a while as he copes with his pain.
He would probably become more reserved. Naruto is usually very open, but as an ANBU commander, he'd have to keep secrets. So he might not be as quick to show his emotions.
He might become more serious and responsible. As a captain, he has to think about the well - being of his squad members.
Naruto could develop a more solemn side. In the ANBU, he'd understand that his actions have far - reaching consequences for the village. He'd be more of a silent protector. Shikamaru would transform into a more decisive figure. His laid - back attitude would be replaced by a sense of duty and urgency. He'd be quicker to make tough calls in order to protect the village and Naruto, his friend, while in the ANBU.
Naruto's personality would likely be more disciplined. ANBU are highly disciplined soldiers. So, he would be less likely to act impulsively. Instead of jumping into situations without thinking, he would analyze first. However, he might also lack some of the warmth that comes from his normal upbringing. He might have a harder time making friends because he's been raised in a more austere environment. For example, he might not be as quick to forgive as he was in the original story, as the ANBU way is more about justice and less about second chances.
His personality might become more cautious. Since he has a greater responsibility as a guardian, he can't be as reckless as he was sometimes in the original Naruto series.
His personality might become more refined. Since the Yamanaka are a bit more sophisticated in their ways compared to Naruto's original upbringing. He could be more calculating and less impulsive, as he'd be influenced by the family's focus on mental prowess.
Naruto would also be more reserved in expressing his emotions. The Naras tend to keep their feelings close to the vest. So, he might not be as openly enthusiastic or angry as he was before. However, his core values of loyalty and protecting his friends would still remain, just expressed in a more Nara - like, understated way.
His personality might become more withdrawn. As a lich, Naruto could be feared by others, and this might make him more hesitant to interact with people. He was always so outgoing before, but now he might keep to himself more.
