One Piece Luffy's crew (character spoilers)

who do you think should join Luffy's crew and why???
I think Captain Foxy should've joined the crew that would of been pretty funny everytime Luffy wants a new crew he could just 3-coin challenge them.

 

I think that Franky will end up joining, Luffy is looking for a musician and in the manga he started playing the guitar when Usopp told him what happened between him and the Strawhats.

But, then again.. Franky already has a group of people he's the head of. I'm sure that Oda will end up surprising us by who's chosen.

 

I am hoping Luffys brother would come to his senses. I have only seen 90 episodes so keep that in mind. They just met up.

 

Oh yeah, Franky practically has to come with them now. I mean, he sings, he can fight, and he's an amazing shipwright... not to mention how much facetime and backstory he's been getting. *crosses fingers* Here's hoping!
