Forum:What will the next strawhat crew member's fighting style be? Kind of Devil fruit or other?

What do you think the next strawhat fighting type will be?
What do you think will be the new strawhats' specialty be? Whether Zoan, Paramecia, or Logia type devil fruit user, or a weapon or body type fighting style?

Please talk abut your perfect scenarios.

It is only my personal fantasy, but I believe the next member should be the cabin boy, and a Logia type user. The proclaimed weakest logia, should belong to the newest strawhat crew member. I think of it as a kind of "breeze breeze" fruit that allows himi to turn into air, avoiding damage, and flying. He should also to some small extent, due to ,lack of proper training, be able to manipulate the air into weapons for him to use. Naturaly, the colder the air, the sharper the weapon! Aside from these charactoristics, My perfect addition would have a deep understanding of the applications to devil fruit powers, and thus be a very useful member to the other devil fruit users. In particular, I imagine him telling Buggy how to become a neer unbeatable pirate (possibly new younko?).

Please discuss your own ideas. --Jety Lefr
