What do you think? Will we see some of the Straw Hats come on to the scene in the big battle? They seem to be quite apart from each other but you never know.

I can see maybe Nico Robin finding her way because the rebels probably have quite a few tricks up their sleeve to move rapidly and Dragon would want to help

Chopper has the giant birds which he could in theory convince to get him back

And maybe Franky can find or invent something to get back

I also see a cahnce for Nami since you never know what they can come up with in a weather island.

Personally I am not sure if I want to see them enter the battle. I kinda like to see how Luffy will do with his improvised crew
