Browsing through One Piece wiki, there's a databook series called One Piece Green: Secret Pieces. I found a picture of Mugiwara Pirates early design. This is the picture.
I can see Zorro, Luffy, Nami, Sanji, and maybe Usopp, Brook, and Chopper. But who is the other two on the left? Did Robin and Franky replace them? Is there any official information about this picture?
