At the impending final clash of Bajrang Gun vs Blazing Dragon Susanoo, Oda should have depicted both Luffy and Kaidou using the FS thus seeing thousands of future possibilities of their respective barraging clashes, feints, evasive maneuvers, biting and ripping each other apart, all those possibilities against each other become fragments of future imaginary Future Sight kaleidoscope surrounding the double spread, with the real-time Monkey God vs Dragon God clash at the center. Since both come to the same conclusion that this direct clash is the only finality they can achieve at the very end of every possibilities. That would make chills running down my spine.
