I think by the end of Wano we should have a new member. we have so many options.

Let's start with Carrot.

Carrot has been traveling with the straw hats ever since Zou. She knows a lot about them and even shared their sorrow for Pedro. She is currently in Wano with the straw hats as well. Now, we all know that each member has to have a dream, and Carrot's is to carry on Pedro's legacy. she was just beaten down by Perospero, one of Big Moms kids. I am lead to believe that if Carrot does not return to Zou after Wano she will join the crew.

Let's talk about Yamato.

So Yamato is the daughter of Kaido, King of the Beasts. If you have read or seen Wano you will know that Yamato hates her father Yamato met Luffy during Wano and is currently helping Momonosuke hide from Kaidos men. This one is likely because Luffy and Yamato have become good friends and I feel like if Yamato wants to escape Wano the best way is to join the crew.

Now let's talk about less likely characters to join

Katakuri:

So, I don't know why but everybody thinks katakuri is gonna join the crew. he is part of Big Moms crew and her son. I see why people think this because Franky fought Luffy and joined because they helped each other but what did Luffy help Katakuri with? Respecting each other because they fought for half a day? No, Not really. I would like to see him join but its highly unlikely

Marco: so Marco is one of the strongest survivors of the Marine ford war and the 1st division commander of the disbanded Whitebeard pirates. I really want him to join and I think this is the most likely of the least likely. he is also currently fighting Queen and King. 2 calamities. I would not be surprised if he joined the crew because it seems highly likely since he is helping them right now at this moment. I wouldn't be surprised if he joins the crew. I could see him fighting Kaido with Luffy (although Luffy wants to fight him alone.) for a while. I really want him to join and I wouldn't be surprised if he did.

Sabo: I know, I know. Sabo is a great character and I want to see more of him. he is strong, has a unique type of fighting style, and knows a lot about the government. He is smart and tactical and good at making plans quickly. he is also highly likely because he is Luffy's brother. I wouldn't be surprised if Luffy had to help him and he decided to join the crew to travel the world on Dragon's orders or something like that. I really want to see more of Sabo and who knows??? Maybe he will even find something out that will shock us all.

This is the list of the new members I think could join. Pls, don't judge this because it's my opinion, and I don't want to be judged by it. Thank you for reading and pls add any suggestions in the comments
