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.
Fem Luffy's fighting style would be more refined. Instead of just relying on her brute strength and rubber abilities, she would have the finesse of a swordsman. This would make her a more well - rounded fighter. She might also be more strategic in battles, thinking things through more like Mihawk does rather than just charging in headfirst like the original Luffy.
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.
Fem Luffy would probably be more worldly. Shanks has a wide range of experiences and connections. Growing up with him, Fem Luffy would have met different people from different backgrounds. As a result, she would be more diplomatic and better at handling various situations. For example, when dealing with other pirate crews or even the Navy, she would know how to communicate effectively. Also, she might have a more refined taste in food and other aspects of life compared to the regular Luffy, as Shanks' crew might have introduced her to different cultures and cuisines.
His dream of becoming Pirate King might take on a different meaning. Instead of being about freedom and adventure, it could be more about domination. Under Doflamingo's influence, Luffy might see the Pirate King title as a way to rule over others rather than a symbol of the freest person on the sea.
His leadership style could change significantly. In the original, he leads with his heart and by example, but in a dark fanfiction, he could be more of a dictator - like leader within his crew, making decisions without much input from others and demanding strict obedience. His goals might also shift from just finding the One Piece and having a grand adventure to seeking power for more self - centered reasons, like revenge or dominance.
Luffy would probably still value his friends above all else. However, as a Celestial Dragon, he might have more power at his disposal. This could make him a bit more confident in his actions, but also more responsible. He might feel the need to use his influence to protect not just his crew, but also the oppressed people he meets, in a more official way.
Luffy's character would likely become more mature. He'd learn discipline from Whitebeard's strict training regime. His view of the pirate world might expand as he gets insights from Whitebeard's long - standing experience.
She'd probably be more serious. Canon Luffy is carefree and naive in a lot of ways. But Fem Luffy raised by Dragon would likely be more cautious and calculating, having grown up around a revolutionary. She might not be as quick to trust strangers.
In terms of character relationships, Luffy's relationship with Usopp could be different. Usopp might be more hesitant to involve her in dangerous stunts or pranks, thinking he needs to be more careful with her as a girl. Also, the relationship with Robin could be enhanced. Robin, being more mature, could act as a sort of mentor to Luffy in matters related to being a female pirate, while still respecting her as the captain. And all the crew members would have to adapt to the new dynamics of having a female Luffy, which would bring about both challenges and new opportunities for growth in their relationships.
Luffy managed to beat Doflamingo through his determination and strategic use of his powers. He also had the support of his friends.
