If Luffy was raised by Whitebeard in fanfiction, his personality would undergo several changes. He would still be the kind - hearted and adventurous Luffy we know, but with added layers. He would probably be more protective of his crewmates, not just in a fight - or - flight way but in a more paternal way like Whitebeard. His sense of justice might also be influenced by Whitebeard's own moral code. He might be less impulsive when it comes to making decisions that affect the whole crew. Instead of just following his gut instincts all the time, he would consider the well - being and opinions of his crewmates more. Also, his leadership style could be a blend of his natural charm and Whitebeard's strong leadership, making him an even more formidable captain.
His personality might become more carefree like Luffy's. He would probably be more laid - back and not worry as much about formalities.
Well, she might become more of a team - player from the start. Whitebeard values his crew like family, and Fem Luffy would probably grow up with that strong sense of camaraderie. She could also inherit some of Whitebeard's leadership traits, but still keep her own adventurous spirit. Maybe she'd be more strategic in battles, having learned from Whitebeard's battle - hardened crew.
Luffy being raised by Doflamingo would be a radical departure from his normal upbringing. Doflamingo's way of life, which involves a lot of underhanded tactics and a disregard for the well - being of others, would shape Luffy in a very different way. He may not have the same innocent and carefree attitude. His goals could be more self - centered, like taking over territories or amassing power for the sake of it. His relationships would also be different. Instead of forming deep bonds of friendship, he might form alliances based on power and convenience. And his approach to challenges would be more in line with Doflamingo's cut - throat style, rather than his own original tenacious but more morally - guided approach.
Percy's personality would be a far cry from the original. He'd be more secretive, for one. Growing up in the Underworld, he'd learn to keep his cards close to his chest. He'd also be more intimidating. His sense of humor might be darker, and he'd have a different moral compass. Instead of the typical heroic values, he'd have values more in line with the Underworld's survival - of - the - fittest mentality. He might be more distrustful of others and less likely to form quick alliances.
His personality would likely be more subdued. Ebisu is a rather proper and disciplined character, so Naruto would probably be less rambunctious.
His personality would likely be more reserved. Manda is not a very expressive or warm - hearted being, so Naruto might not be as outgoing as in the original story. He'd be more cautious and calculating, having learned from Manda's survival instincts.
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.
He would probably be more haughty. Hera has a certain air of superiority, and being raised by her might make Percy think he is above others in some ways. He could also be more secretive, as Hera often has her own schemes and Percy might learn to keep things to himself.
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.
