How would Naruto's personality change if he was raised by Manda in a fanfiction?

His personality would likely be more subdued. Ebisu is a rather proper and disciplined character, so Naruto would probably be less rambunctious.

Naruto's personality would change a great deal. He'd be less naive. Pein has seen a lot of the dark side of the world, and raising Naruto would expose him to that. So Naruto would be more world - weary. He may also be more ruthless in achieving his goals, as Pein doesn't shy away from extreme measures.

Naruto might be more assertive. Since Kushina was a strong - willed person, Naruto would likely inherit some of that. He would be less likely to be pushed around and more likely to stand up for himself earlier. Also, he might be more family - oriented as he would have grown up with a loving mother figure in Kushina.

Naruto's personality would be a blend of his original self and Zeref's traits. He may still have his determination but it could be a darker kind of determination. His sense of humor would probably be lost as Zeref doesn't seem the type to encourage light - heartedness. Also, he could be more secretive, not as open as he is in the original Naruto series because Zeref often keeps his own council.

He'd probably be more reserved. Kakashi is not as boisterous as some others, so Naruto might pick up on that. For instance, he might not shout as much about becoming Hokage right away.

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.

His personality might be more reserved. Tsunade is not as boisterous as some of Naruto's other mentors. So he could be less likely to jump into things without thinking. For instance, he might analyze a situation more carefully before acting.

His sense of loyalty might change. While Naruto is fiercely loyal to his friends and village in the original story, being raised by Catwoman could make him more loyal to a smaller, more select group. He might also be more cautious about who he gives his loyalty to, as Catwoman is often on her own and has to be careful about who she trusts.

Naruto would likely be more empathetic. Kenshin has a deep understanding of the pain of others due to his own past. Naruto, under his care, would develop a stronger sense of empathy. He would be more likely to try to understand the motives of his enemies before attacking. His sense of humor might also change. It could become more subtle, influenced by Kenshin's more serious nature.

He might be more calm. Since the female Kurama could be a stable influence, Naruto wouldn't be as impulsive.
