Your speculation is unlikely, as the visual style appears the same as the one used in the flashback from the pilot episode. I predict your "Gold Ninja" is either Wu or the First Spinjitzu Master, but I suppose if not either of those it could be the Green Ninja. One more note, he appears armed with one of the same curved elemental sword depicted in the book, called "Warriors of Stone", art cover. But of course, what does an explorer like myself know?
