well I guess everything with zoro is a not, cuz I dont see him working together, same for luffy. And about franky, I dont know so I choose this one.

Interesting question. I think Nami, Chopper & Robin could work well together, as they are likely 3 of the smartest crews among the 9 and don't intend to go on their own.

cuz they're the monster trio :D lol

They are very strong!!!!All of them!!!!
Also they combine 3 different kinds of power.I mean Luffy works with his body,Zoro uses his swords and Sanji <3 his legs.
It's amazing when they are fighting together against their enemies.

Interesting..well I find that Luffy,Usopp and Chopper make an awesome trio,especially when it comes to laughing,but I mean I still think the three are great trio..but I think most of those could work.

It was hilarious when they try to imatate the Voltron Force without Robin

I think that they are the best team. They are the strongest in the crew. Also, when Zoro and Sanji actually work together for a change, they make a very dangerous pair. However, with them fighting each other more than the enemy, the two of them would never really work out. However, throw Luffy into the mix and things calm down a bit. For some reason, they don't fight as much with each other when they are with Luffy. Both Zoro and Sanji become more serious when Luffy is around them during battles.

Luffy and Zoro are from my point of veiw the strongest on the crew.
Put to gether = POWN!!!

Not Luffy, Zoro, and Sanji because Zoro and Sanji fight all the time, but just Luffy and Zoro would work out very well.

heloooooo?!?!?!?!?!??! the demon trio?????? they r the three stingiest guys so if you give them all one common enemy...just hope its not you!

Sanji, Zoro and Luffy... Good team for winning a fight. I think Nami and Luffy make a good team as well, since Nami seems to be able to motivate Luffy into action. Lol. Also, Zoro and Luffy, unless it's somewhere that requires a good sense of direction. XDDD

awesome would win any fight but only sanji has a brain to make a pan instead of going head on

The three strongest fighters together makes a human nuclear bomb that will make you shit your pants

Luffy & Sanji & Usopp are mine but my second choice would have been Chopper & Usopp & Nami.

Monster trio ofc!

Well I kinda ship them.
But even if you don't they are interesting to watch.
