I've only ever seen, like, two episodes of it. So I need some help. Someone on ebay has requested One Piece stationary and, well, I don't know who the main cast members are. I know Luffy. (Is that how you spell his name?) And that triple-sword Zolo/Zoro guy. (Roronoa?) And I'm vaguely aware that there was a chick (Nami? Namine? Nanami?) and a blond-dude in a suit with a ... cigarette? lollipop? idk. Are there other "main" characters, or are they it? Like, when someone asked me to do Bakugan, they asked for, I think, four characters, but when I was researching them I found out there were actually six in the team dynamic. So I wound up making a six character pack in the end. So... Are there actually five or six main characters on One Piece, or are those four it?
Thanks to anyone who can educate me!
