One idea could be that Luffy and Whitebeard's crews team up for a common goal, like fighting against a new and extremely powerful enemy that threatens the whole world of pirates. Luffy's carefree and determined nature could contrast and also complement Whitebeard's more fatherly and protective leadership style.
A plot could revolve around a tournament on an island. Ace, Sabo, Luffy, and members of Whitebeard's crew participate. The prize is a powerful devil fruit. Each character has their own reasons for wanting it. As the tournament progresses, old rivalries are rekindled, new friendships are formed, and they all discover more about themselves and their place in the pirate world.
Well, perhaps in the fanfic, there could be a plot where Whitebeard decides to train Ace, Sabo, and Luffy in a new form of combat. This training could lead to them developing new powers or techniques. Also, they might get involved in a political intrigue within the pirate world while associated with Whitebeard. Like, they have to deal with other pirate lords who are jealous of Whitebeard's influence and try to undermine him by targeting the three brothers.
Their relationship could develop through mutual respect. Luffy respects Whitebeard as a powerful and respected pirate, and Whitebeard respects Luffy's determination and potential. For example, they could start with a simple exchange of stories about their adventures at sea.
Maybe in the fanfiction, a smart Luffy figures out a way to read Poneglyphs with Robin's help. This new ability draws the attention of both the World Government and other pirate crews. They then have to go on a journey to protect this new - found knowledge while also using it to uncover more secrets about the Void Century.
A possible storyline is that Fem Luffy has a special mission related to Whitebeard. She could be on a quest to find a hidden treasure that was once connected to Whitebeard's past. Along the way, she teams up with members of his crew and they face various foes together. As they journey, they learn more about each other's dreams and values, and Fem Luffy's presence might even inspire some of the crew members to pursue new goals.
One common theme is the bond between them. Fanfictions might explore how Ace's relationship with Luffy and Whitebeard affected his decisions and growth. Another theme could be adventures that they might have together that weren't shown in the original manga or anime. For example, they could go on a special mission to a new island.
A common theme in Whitebeard x Luffy fanfiction is the bond of mentorship. Whitebeard could see himself in Luffy, a young pirate with big dreams. He might take Luffy under his wing and teach him about the history of the One Piece world.
One idea could be Naruto having Whitebeard's sense of honor and leadership in the ninja world. He might gather a group of ninjas similar to how Whitebeard had his crew, and they fight for justice and protect the weak. Another plot could be Naruto having to deal with Whitebeard's old enemies reincarnated as well, leading to epic battles.
Well, the plot could involve Luffy being taken under Whitebeard's wing after an encounter. Whitebeard, seeing Luffy's potential, decides to train him. Luffy would then be exposed to the different fighting styles of the Whitebeard pirates. He'd probably have sparring matches with the stronger members, like Marco. This would make Luffy even stronger and more well - rounded in his abilities.
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.
