Nami would probably be devastated. She has been with Luffy through so much, and his death would be a huge blow. She might become more withdrawn and serious, as Luffy was often the one to bring out her lighter side.
The Straw Hat crew would probably be very surprised at first. Nami might worry about how Hancock's presence would affect their finances, since Hancock is used to a more luxurious lifestyle. Usopp would be in awe of Hancock's beauty and powers. Chopper would be excited to have Hancock around, as she could potentially teach him about different kinds of medicine from Amazon Lily. Zoro might be a bit skeptical at first but would come to accept it as long as Luffy was happy.
The Straw Hat crew would be in for a big shock at first. But then they would quickly rally around Luffy and Nami. Robin might offer her wisdom on raising a child and share stories from her own past. Franky would build amazing things for the baby like a super - safe crib or a high - tech stroller. Brook would play music to soothe the baby. And they would all work together to make sure the baby has a great life on the ship.
Shanks might interact with Luffy's crew in a very friendly and father - like way. He could pat the crew members on the back, give them words of encouragement, and share his experiences with them.
I think it has the potential to be very engaging. A marine joining Luffy's crew would bring in a clash of ideologies and force both the marine and the crew to adapt and grow. It could lead to some unexpected plot twists and character developments.
The Straw Hat crew's reaction would be quite diverse. Usopp might make some jokes at first about Luffy's new look but would support her all the same. Robin would be very observant and might notice how Luffy's new form could change the crew's dynamics. Franky would be his usual self, shouting some over - the - top phrases about how cool 'female - Luffy' looks. Brook would probably make some bone - related puns about Luffy's new femininity while still respecting her as the captain. Overall, they would all adapt in their own ways and continue to follow Luffy on their adventures.
If a marine joins Luffy's crew in a fanfic, it could be quite interesting. At first, there might be a lot of distrust among the crew members. After all, they've been fighting against marines for a long time. But if the marine has a strong sense of justice that aligns with Luffy's own view of right and wrong, they could gradually be accepted. For example, the marine might bring in some new combat techniques or knowledge about the navy's operations that could be useful to the Straw Hats.
In fanfiction, if Ace joins Luffy's crew, it would be an amazing addition. Ace's powerful fire abilities would make the crew even stronger in battles. He could also bring a different dynamic to the group, as he has his own personality and backstory. His relationship with Luffy would be a central focus, and we might see more brotherly bonding moments on the ship.
The Straw Hat crew would have a mix of reactions. Franky might start building a special nursery on the ship, using all his engineering skills to make it safe and comfortable. Robin would be a source of calm and knowledge, sharing stories about pregnancies in different cultures she's read about. Brook would be playing gentle music to soothe Nami. And Luffy, as the father, would be constantly by Nami's side, sharing his positive energy and telling the baby stories about their adventures, even though the baby can't hear them yet. Overall, the crew would come together to support Nami and the new life coming into their world.
