Naruto would likely be more strategic. In Squad Zero, he'd need to plan ahead for missions, so his impulsive side might be toned down. He'd still have his positive energy, but it would be more focused on motivating his squad rather than just being carefree. He'd also be more diplomatic, having to deal with different personalities in the squad and other ninja groups.
In this fanfiction, as Captain of Squad Zero, Naruto's personality would evolve. His determination would be channeled into building a strong and efficient squad. He'd be more patient, especially when training new or less - experienced members. His loyalty would extend not only to his friends but also to his squad. He would also become more of a thinker, analyzing situations more thoroughly before acting. For instance, when facing a difficult enemy, he wouldn't just rush in like he used to. Instead, he'd consider the strengths and weaknesses of his squad and the enemy, and then come up with a well - thought - out plan.
He might become more serious and responsible. As a captain, he has to think about the well - being of his squad members.
He might become more responsible. As a captain, he has to think about the well - being of his whole squad, not just himself. So he'd be more cautious in battle and in decision - making.
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.
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.
One possible storyline could be Naruto leading Squad Zero in a mission to protect a hidden village from a powerful dark force. He'd use his unique jutsu and leadership skills.
If Naruto becomes involved with Slenderman in a fanfiction, his usually cheerful and determined personality might become darker. He could be more withdrawn as he grapples with the strange and often terrifying aspects of Slenderman's world.
His personality might become more refined. Instead of being the rowdy Naruto we know, he could be more composed and polite due to the influence of the daimyo's court.
He might become more serene. Since Sadaiam might have a calmer and more nature - centered philosophy, Naruto could adopt some of that. He'd be less impulsive in his actions and more contemplative.
Naruto might become more aggressive at first. The influence of Venom could bring out his darker side. But as he gets used to it, he would learn to balance it with his usual positive and determined self.
Naruto might become more calm and collected. Goku has a certain simplicity and focus in his personality. Naruto could pick up on that and not be as impulsive as he usually is.
Naruto might become more reserved. Growing up under Zeltrech, he could be exposed to a more sophisticated and perhaps less rowdy environment compared to Konoha. So instead of his usual loud and brash self, he could develop a more calm and calculated side.
