During an interview for One Piece Log 27, Oda talked about the creation of the eleven supernovas.
Question: Who has more highlight scenes than you imagined?
Eiichiro Oda: “I have to mention Trafalgar Law.”
Actually, it’s not too much to say that all Supernovas have more highlight scenes than I imagined. I created supernovas right before the chapter where they got introduced.
None of them existed in my plot notebooks before that chapter. I was in a desperate situation, worrying, “At this rate, the Sabaody arc will not be interesting enough.” Then, inspiration for 9 supernovas came to my mind unconsciously. I should have reduced the number of Supernovas since they were too many, but after all, I made all of them appear in manga! I’m really surprised they’ve survived till now since I thought about half of them would drop out of the tough New World already.
They are the worst! They are the worst generation, indeed.
I imagined Eustass Kid would become an important character, but… Trafalgar Law! I didn’t imagine he would become such an important character. “Weekly serialization is a wonderland.”
