The grandson of the Beast Pirates could be a young boy named Leo. Leo grows up seeing the destruction caused by his family. He secretly dreams of becoming a peacemaker. One day, he stumbles upon a map that leads to a powerful weapon. Instead of using it for evil like his family might have, he plans to destroy it. He embarks on a dangerous adventure, facing many challenges and making new friends who support his cause. In the end, he manages to destroy the weapon and starts a new era of peace in the regions once terrorized by the Beast Pirates.
Fem Luffy would probably bring a lot of energy. She might be more empathetic in some ways compared to the original Luffy, which could help in resolving internal crew conflicts. For example, if two crewmates have a disagreement, she could use her charm and understanding to smooth things over.
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.
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.
He could be rebellious. Tired of the cruel ways of the Beast Pirates, he might rebel against their values. He would be determined to create his own path, not following the violent and greedy ways of his predecessors.
Some of the pirates might be excited to meet Sabo, especially those who knew Ace well. They could see Sabo as a link to their fallen comrade. Others might be more skeptical, fearing that Sabo could bring trouble from the Revolutionaries. Overall, it would be a mix of reactions depending on the individual members of the Whitebeard Pirates.
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.
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.
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.
