Watching the SH crew and Luffy grow and get more powerful, got me thinking. Almost every really really powerful pirate crew has a large amount of crewmen backing them with tons of ships. Every Yonkou has at least a fleet of 5-10, with WB well above that number. 16 ships I think. Which makes me think.
At the rate of power and skill the crew are getting, will it soon be time for Luffy (captain) to split up and make his fleet even more poewerful? It can happen.
Chiefs of the crews:
Medical crew:
Chopper is
Navigation crew:
Nami
Shooting crew:
Ussop
Artifacts/historical crew:
Robin
Food/cooking crew:
Sanji
Musical crew:
Brook
Repairs/maintenance crew:
Franky
And Zoro would just end being by Luffy's side since (and I just found this out very very recently) he is Luffy's first mate.
I can totally see it happening as the NW story arc progresses. It'll take some time but I think Oda will do it eventually.
