User blog comment:Akali95/Why? Because F*ck logic that's why!/@comment-2226235-20130329033109

As an avid reader of fantasy I have experience with different series having different logic but I do believe that every series should set up it's logic (even if it is that there is no logic ie. Bobobo-bobo-bobo) and stick to it. That said, I agree with your version of One Piece logic although for the species, you should look at the races category page because it lists several other races we haven't seen yet or have barely seen like Wotans.
