What terrible ships, most of them make no sense. Like doesn't Franky already have Kiwi and Mozu? He and Robin have certainly shown no interest in each other. And where is Hancock? Luffy rejected her outright, but she still makes more sense than Nami.
But it's all moot anyway, Oda said in a December 2006 Jump Festa interview that there'd be no romance between the nakama, so it's just some tumblrina-like fanwank.
