Well, Naruto's skills like his shadow clones could be a great asset. He could use them for various tasks on the ship, from cleaning to helping in battles. His determination would also match the Straw Hats' spirit.
Luffy would probably be excited. He loves having new and interesting people on his crew. Zoro might be a bit cautious at first but would come to respect Naruto's fighting skills. Nami would see Naruto as someone who could be useful for his abilities.
In a fanfiction where Naruto joins the Straw Hats, the dynamic of the crew would change significantly. Naruto is used to working in teams in his own world, and his experience in forming strong bonds with his comrades would blend well with the Straw Hats' own sense of camaraderie. His ability to make friends easily would also help him fit right in. Plus, his shadow clone jutsu could be used for various tasks on the ship, like helping with repairs or keeping watch.
In such a fanfic, there might be a lot of interesting character dynamics. The admiral would have to adjust to the Straw Hats' carefree and family - like atmosphere. There could be conflicts at first, as the admiral is used to a more rigid military structure. But over time, they could grow to love and protect their new crewmates just like the others.
In this kind of fanfiction, Naruto might face a whole new set of challenges in Suna. He could bring his unique skills and determination to Suna. Maybe he'd form new friendships with Suna ninjas and help improve Suna's overall strength. He could also share his knowledge about certain jutsus that are unique to Konoha.
Well, he would probably make the Straw Hats extremely powerful. His ninja skills like shadow clones and rasengan could be used in creative ways during battles at sea. For example, he could use shadow clones to man the ship while the others fight or use rasengan to blast away powerful sea monsters.
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 She might become more withdrawn and serious, as Luffy was often the one to bring out her lighter side.
Well, in this fanfic, Naruto being banished from his home village and joining Kumo could lead to a lot of character development. He would have to adapt to a different culture and way of life. For example, Kumo has its own traditions and values that are different from Konoha's. He might also have to prove himself all over again to gain the trust of the Kumo villagers and ninja. This could be a great opportunity for him to grow stronger in different ways, like training with Kumo's powerful ninja masters and learning their combat techniques.
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.
In a fanfiction where Smoker joins the Straw Hats, it could be really interesting. Smoker is a marine, and his sense of justice is quite different from the Straw Hats' view of freedom. At first, there would likely be a lot of tension. But as time goes on, he might start to understand their way of life. For example, he could see how they help the weak and oppressed in their own unorthodox way. He might also learn to be more flexible in his views of right and wrong, as the Straw Hats often operate outside the normal rules. And his combat skills would be a great addition to the crew, making them even more formidable in battles against stronger enemies.
They might have an epic celebration. The Straw Hats would be excited to see Shanks, especially Luffy. Luffy would probably challenge Shanks to a friendly duel or just be overjoyed to show him how far he's come. Shanks would be proud of Luffy and his crew, and they could all share stories of their adventures over a big feast.
