Blackbeard's crew is also a diverse bunch. His more aggressive members like Burgess might be eager to start a fight with Luffy's crew. However, some of the more cunning members could be thinking of ways to use the situation to their advantage. They might try to manipulate Luffy or his crew into making mistakes. And if Blackbeard decides on a certain course of action, his crew would generally follow, but there could be some internal dissent depending on the situation.
Blackbeard would probably be very interested in the magic in the Fairy Tail world. He might try to steal some of the powerful magic items or learn magic for himself. He could see the mages as a threat to his plans if they oppose him, but also as potential allies if he can manipulate them. He would likely use his cunning and power - hungry nature to his advantage in this new world.
It could also be that instead of fighting right away, there's a tense stand - off. Luffy, remembering Ace's past encounters with Blackbeard, would be full of anger and distrust. Blackbeard, on the other hand, might try to taunt Luffy, trying to get him to make a rash move. The situation could escalate slowly as they exchange words, with their crews on edge, waiting for the first sign of action.
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.
Well, in such a fanfiction, Ace might be worried about Luffy. Since Blackbeard is a dangerous character. He could decide to go and find Luffy to protect him. Maybe he'd start looking for Blackbeard too, to make sure he doesn't harm his little brother.
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.
