When Zoro spoke with Chopper in Alabasta, Chopper asked about Luffy, and wondered if the crew was really alright; they all seemed wild and independent to him.
Zoro said that is was true, and that everyone has different goals, but he said this: “What is teamwork anyway? Is it just about rescuing and protecting each other? To some people they believe it. But to me it sounds like a kids game. Everyone should do what they can with their lives on the line, and when they can’t finish, they say to the next guy ‘If you don’t finish it, I’ll beat your ass!’“
I found a direct example reading Chapter 414, (checking out Sanji’s powers to get an idea on his raid suit lol) where Usopp is saved by Sanji. Usopp is nearly dead and he apologizes to Sanji, and Sanji said it’s alright; everyone has something they can and cannot do. He also says “In the worst situation, we have the best chance!” Which is something to note; it’s gonna have a play in how the crew member honors their role in the crew for this upcoming arc.
It was just a great thing to see from two characters who literally hate each other, still find respect for each other’s strengths and that they have to work together; we saw this in the Davy Back Fight back on Long Ring Long Island where they combined strengths to take down the opposing offense.
I bring this up because Wano is the only arc besides Fishman Island where the entire crew has been together all in the same place, at the same time; the exception being Luffy in jail.
They separated the captain, and he’s been incarcerated. The thing is, usually they’re divided in multiple different groups, and that’s been plot building; I remember losing track of characters all the time despite binge watching it. This isn’t gonna be too present in Wano, the crew is split up right now, but we’ll see them assemble with their allied forces and make a move.
We also hardly saw them do anything on Fishman Island, so I believe we’ll see the true extent of every crew member’s powers probably in the second act of Wano Arc.
