Conqueror's Haki Work - Luffy

The moment Luffy and Kaido clashed with Conqueror’s coating, the heavens literally parted. This visual motif—the split sky—has been the signature of Yonko-level combatants like Shanks, Whitebeard, and Big Mom. By achieving this feat, Luffy did not just win a fight; he announced to the entire world that he had officially joined the ranks of the Emperors.
