@sadrhg:
If by crews you mean the subordinates and commanders such as Ace or Lucky Roux then yeah. If by crews you mean the members who aren't commanders and the normal people then no.
Really I don't see why people make a big deal about the Yonkou's crews. I haven't seen any evidence that the average (i.e. not like Ace or Marco) Yonkou crewmember is significantly stronger than the average marine. And we all know that marines are cannon fodder….
I bet Crocodile or Moria could kill most of the Yonkou's normal crewmen.
And the Marines have of course the marines. And chances are the Shichibukai have their own private armies.
The proof is right here:
[Red-Hair Pirate Crew (New Recruit)]
[Rockstar]
[Bounty: 94 Million Berries]
Rockstar: Nah, I'm still just like, a recruit.
Although I used to be a pirate, originally.
A pretty well-known one, in my opinion…
Hey... you guys all know Rockstar, right...?
Pirate: Nahh... who's that...?
Rockstar: ...HUH?!!
That's Marco talking. With a bounty of 94 million, he's a recruit on Shanks' ship.
That should tell you something.
