It's even more impressive that, from what I recall, the Supernovae were all but made up on the spot for the Sabaody arc because Oda's editor wanted them there to provide a sense of scale for the Grand Line adventure, or something like that. Then Oda made Law, well, Law and it's all been uphill from there.
