''Remembers "Juraquille Mihawk" and all the variations of Oars and Thriller Bark. ¬_¬'

There is a reason we developed a pecking order for translated names that went;

manga -> SBS -> Data books -> Anime -> English dub -> Fan translation

Basically the manga version came first, following by the SBS in second and so fourth, with the prior one being regarded as "most correct", in short the manga name overrides a name in the SBS or something like this.... when the manga didn't provide, a name, we had to move down the line until we had a name.

Because this happens so often we had to have this pecking order, because not only did fan names get proven wrong, but we also could end up with multiple versions of a name. Its no big deal, you just move on.
