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.
If Luffy had a Devil Fruit that made him invisible, it could make him a bit more mischievous. He might start playing pranks on his crewmates more often. But his core values of loyalty and determination would remain. He would still use this power for good in battles, sneaking up on enemies and catching them off - guard. The new power would just add a different flavor to his already vibrant personality.
His personality would stay largely the same in terms of his goals and values. He still wants to be the Pirate King. But in social situations, he could be more cautious. As a girl, he might face different types of challenges when interacting with other pirates or people in general. He might have to rely more on his wits rather than just brute force in some situations, which could be a new aspect of his personality development in this fanfic.
His core personality might not change much. Luffy is still likely to be as carefree and adventurous as ever. However, he might become a bit more sensitive to certain things, like how people treat girls. He'd still be fearless in the face of danger, but could use his new form to his advantage in different ways, like when dealing with female characters who might be more likely to trust a girl.
The theme of acceptance is quite common. Fem Luffy often has to be accepted by the other characters in the story. This could be because she's different due to her gender or her slightly different personality traits. Also, the theme of self - discovery is prevalent. As fem Luffy navigates the pirate world, she discovers more about herself, her abilities, and her place in the grand scheme of things.
One popular luffy and fem luffy fanfiction is 'Fem Luffy's Adventure'. It shows a different side of Luffy if she was a female, with unique storylines and character developments. Another one could be 'Fem Luffy in a New World' which explores how fem Luffy might interact with the other characters in the One Piece world in new and interesting ways.
Some fanfictions also pair Luffy with Hancock. Given Hancock's infatuation with Luffy in the original series, it's not a stretch to develop a full - blown love story. Her powerful status as a pirate empress and Luffy's carefree nature can create an interesting dynamic, with Hancock trying to win Luffy's heart while he is mostly oblivious to her romantic intentions.
She could be a former pirate captain herself. Maybe she was one of the most feared pirates in her time, and her skills and reputation were passed down to Luffy in some way, even if he didn't know it was from his mother.
Well, in such fanfiction, Luffy's character often becomes more aware of his emotions. Usually, he is so focused on adventure and being the Pirate King, but when he falls in love, he starts to think about someone else's feelings. For example, he might be more hesitant to go on extremely dangerous adventures without considering how his loved one would feel.
