Nefertari Vivi is the princess of Alabasta.
Vivi traveled with and assisted the Straw Hhat Pirates for almost the entire Alabasta Saga and strongly considered joining their crew after Crocodile’s defeat. Though she ultimately declined their offer in favor of working to restore her country, she remains closer to the Straw Hats than anyone else outside of their crew. She and Carue are now regarded as honorary members of the Straw Hat Pirates, at least by Luffy and the others. In the future we might see her joining up with the Strawhats.
#Marco The Phoenix
Marco the Phoenix is the former 1st division commander of the Whitebeard Pirates. He was Whitebeard’s closest confidante and his right-hand man. After the Payback War, Marco works as a doctor at Whitebeard’s home village.
The last order that Whitebeard gave him was to protect Luffy while in Marineford war so the best way to ensure that Luffy lives is by joining the crew.
Marco joined the Ninja-Pirate-Mink-Samurai Alliance against Kaido and Big Mom in Onigashima.
Bartolomeo is the captain of the Barto Club and the commander of the 2nd division of the Straw Hat Grand Fleet.
Bartolomeo, an original admirer of Luffy from the time of Loguetown and onward, admires the crew in its entirety, saying he followed all of their actions.
What job the Straw Hat Crew actually requires is a Guard who basically protects the ship during their adventure in various islands in the New World. This is emphasised by the fact that in almost every arc, the crew splits up and somebody is left behind to protect the Sunny. With Bartolomeo’s Barrier Fruit this problem can be solves if he creates a barrier around Sunny and the crew can go adventuring into the islands.
O-Tama is a girl from the region of Kuri in Wano Country. She is a kasa weaver and a kunoichi in training who follows the Kozuki Family.
When Ace visited Wano, Tama formed a bond with and had faith in him. Tama wanted to go out to sea with Ace, but he told her that she was too young at the time. He promised that he would take her with him if she became a kunoichi by the time he returned and Tama waited for him since.
What if Luffy keeps Ace’s promise and takes O-Tama with him?
