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.
Well, a plot twist could be that in this fanfiction, Fem Luffy has a special power due to being raised by Shanks. Maybe Shanks unknowingly passed on some of his unique haki abilities in a different way to her. And this power becomes a key factor in her journey. For example, she might be able to use a form of haki that can calm the most violent of sea creatures, which helps her and her crew in many dangerous situations at sea.
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.
She would likely be much more hardened. Instead of the somewhat naive Harry in the original story, Fem Harry raised in Azkaban would be street - smart. She'd be more distrustful of others, having grown up among criminals. Her view of magic would also be different, perhaps seeing it more as a tool for survival rather than something to be used for fun or in school competitions.
They could start with a big hug. Then Shanks might tease Luffy about his still - crazy appetite. Luffy, in turn, could show off his new crew members to Shanks.
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.
Another possibility is a Devil Fruit that gives her the power of telepathy. Fem Luffy could then communicate with her crew without speaking, which would be very useful in stealth missions. She could also use it to read the minds of her enemies, getting an edge in battles. This would completely change the dynamics of her relationships with other characters in the story as well.
Her sense of justice might be more influenced by Whitebeard's code. Whitebeard has his own set of values that his crew follows, and Fem Luffy would likely internalize those. For instance, she might be more protective of her crewmates from the start, rather than just going on adventures without much thought for the safety of others as the original Luffy sometimes does.
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.
The fanfiction could also explore how Fem Luffy's view of the world is shaped by Mihawk. Growing up under his tutelage, she might have a different perspective on pirates compared to the original Luffy. Maybe she would be more focused on honing her skills first before setting out on a grand adventure. Also, her encounters with other characters in the One Piece universe would be different. For instance, when she meets Zoro, there could be a whole new level of rivalry or camaraderie since they both have a connection to Mihawk.
In a Fem Luffy raised by Dragon fanfiction, she could inherit some of Dragon's mysterious abilities. Dragon seems to have some sort of weather - related powers, and Fem Luffy might develop her own version of these powers. Her journey to become the Pirate King would also be different. Instead of just having the simple dream of freedom like the original Luffy, she might be aiming for a more complex goal of creating a new world order while still being a pirate. And her character might be a bit more brooding and less carefree as she has been brought up in a more intense environment.
