There could be some of Dragon's comrades in the revolutionary army who become important figures in Luffy's upbringing. For example, a veteran revolutionary who teaches Luffy about the history of the world and the wrongdoings of the World Government.
In a 'Luffy raised by Whitebeard' fanfiction, Luffy's character would be greatly influenced. Growing up with Whitebeard, he would be surrounded by a different set of role models compared to being raised by Dadan. He would likely have a different view on the concept of piracy. Whitebeard's crew values family above all else, and this would seep into Luffy's values. Luffy might be more patient in his journey to become the Pirate King, as he would have learned from Whitebeard's long - standing presence in the New World. He could also have a different relationship with the other Yonko, as he would be seen as part of Whitebeard's legacy. This would change the power dynamics in the One Piece world significantly, and the story could explore how Luffy navigates through these new challenges and relationships while still holding onto his own dreams and values.
Well, a plotline might involve Luffy being trained in stealth and strategic planning by Dragon. This would add a new dimension to his character as he usually just charges head - first. Also, there could be a story where Luffy has to keep his relationship with Dragon a secret from his crew at first, and the internal struggle he faces about that.
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 Luffy x Nami Lemon New World fanfiction, there could be a situation where Nami is kidnapped by a group who wants to use her knowledge of the New World and the lemons (maybe there are special lemons with unique properties there). Luffy, being the fearless captain, sets out on a solo mission to rescue her. Along the way, he meets some old friends and new allies. When he finally reaches Nami, they both realize their feelings for each other have grown even stronger during this ordeal.
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.
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.
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.
In a Luffy x Nami Lemon New World fanfiction, Luffy could develop his ability to understand Nami's more complex emotions. The lemons could be a symbol of something precious to Nami, and Luffy has to respect and protect that. He might start to see Nami not just as a crewmate but also as someone he has deep feelings for. Nami could develop her sense of adventure even more. She might be initially cautious about the lemons in the New World, but as she explores more with Luffy, she becomes bolder. Their characters could also grow together as they face new enemies in the New World who are after the lemons. This would test their loyalty to each other and the crew, and they would come out stronger as individuals and as a couple (in a platonic or romantic sense depending on the direction of the fanfiction).
