Whitebeard could be the most captivating. As the captain of the Whitebeard Pirates, his wisdom, power and the respect he commands would be a great element in the fanfiction. His interactions with Luffy, a young and ambitious pirate, could lead to some profound exchanges. Maybe he would see a bit of his younger self in Luffy and offer some valuable advice.
Luffy himself could be the most interesting. His reactions to the new environment and the powerful Whitebeard Pirates would be fun to read. He's always full of surprises and his ability to make friends out of enemies is quite remarkable.
It could be Ace. Since Ace was part of Whitebeard's crew and also Luffy's brother. His role in this meeting could be very crucial. He would be like a bridge between the two different worlds of Luffy and Whitebeard. His loyalty to Whitebeard and his love for Luffy would add a lot of emotional and interesting elements to the story.
Well, perhaps there will be some epic battles. Luffy's crew, the Straw Hats, could face off against some of the Whitebeard Pirates in a friendly spar. Luffy might use his Gear Second or Gear Third to show off his power, while the Whitebeard Pirates display their own unique combat skills. And in the end, they could gain a mutual respect for each other.
I think Luffy and Whitebeard himself would be the most interesting. Whitebeard is a legendary figure. Luffy would be eager to prove himself in front of him. And Whitebeard would see the potential in Luffy. Their exchange could be filled with wisdom from Whitebeard and Luffy's naive yet charming responses.
A cool plot would be when the Whitebeard Pirates meet Luffy while he's on a quest to find a rare Devil Fruit. They too are interested in that Devil Fruit for some reason. Instead of fighting over it, they decide to team up. Luffy's unique perspective and the Whitebeard Pirates' experience combine to create an epic journey filled with challenges and new discoveries.
One interesting storyline could be Fem Luffy joining the Whitebeard Pirates on a special mission. Maybe they have to rescue a kidnapped crewmate from a powerful enemy. Her unique abilities as a female version of Luffy, like her stretching powers, could play a crucial role in the rescue.
Whitebeard himself is often a very popular character in fanfiction. His powerful presence and fatherly role in the crew make him a central figure. Writers can explore his leadership, his past battles, and his relationships with the other crew members.
Well, if the Whitebeard Pirates join Luffy in fanfiction, it would be a game - changer. Luffy already has a diverse crew, but adding the Whitebeard Pirates would mean a whole new level of firepower. Think about it, the Whitebeard Pirates have their own strong fighters like Marco. With them on Luffy's side, they could raid more dangerous territories, maybe even find the One Piece faster. And there would be a lot of interesting character interactions. Luffy's carefree nature might clash and also blend well with the more experienced members of the Whitebeard Pirates.
In this fanfiction, Luffy might initially be in awe of Whitebeard. He could be eager to learn from the great pirate. Maybe they'll team up for a short adventure against a common enemy, like a powerful marine force. Luffy's energy and Whitebeard's experience could make for an interesting dynamic.
In fanfiction, when the Whitebeard Pirates meet Luffy, they might initially be cautious. Luffy's reputation as a rising star in the pirate world could make them curious. Maybe they would test his strength. For example, some might engage in a friendly sparring match with him to see what he's made of.
The story could develop in many ways. One way is that they could start by exploring new islands together. The Whitebeard Pirates' experience would help Luffy's crew avoid some of the usual pitfalls. And in battles, they could use combined strategies. For instance, Luffy's Gear techniques combined with Whitebeard's fruit powers. Another aspect could be that the two crews' different cultures and values could merge, creating a new pirate culture within the story. This could attract more characters to join them, expanding their influence across the One Piece world.
