The Three-Sword Style of the Supreme King! Zoro vs. King

With his swords now infused with both Armament and Conqueror's Haki, emanating the black lightning and a green smoke-like aura, Zoro with his newly dubbed King of Hell Three Sword Style, faces off King yet again. As they clash, Zoro lands manages to make King bleed and also rips up the Lead Performer's mask. Zoro finally figures out that King's durability and speed are directly linked to the flames on his back―that once the said flames go out, King's speed increases, but his defense gets weaker. A couple of Beast Pirates see King without his mask and observe that he has black wings, white hair, and brown skin. They say that he is of a race so rare that the World Government awards 100,000,000 Berries to those with information about their existence. King overhears this and burns them to death. King and Zoro continue their battle outside the Skull Dome. King finally acknowledges Zoro's strength and the danger he poses. Zoro accepts the compliment and vows to end Kaido's and the Beasts Pirates' reign. King rebuffs this and declares that Kaido will be the King of the Pirates. Zoro rejects this declaration and attacks. King recalls the first time he met Kaido. Years ago both Kaido and King (who back then went by Alber) were both World Government test subjects on Punk Hazard until Kaido broke them out. King agreed to join the pirate crew Kaido was forming after he guaranteed that he would change the world. After noting how strong Alber was, Kaido gave him the name "King" and promised that he would never betray him and made him his right-hand man. Back in the present, King attacks with Imperial Flaming Wings, which sends a magma-like flame dragon onto Zoro but Zoro is able to counter and cut King. As the battle continues King sends a multitude of magma-like flame dragons onto Zoro. The flames try to engulf Zoro, but he cuts them down while he makes his way towards King. Zoro attacks with King of Hell, Three Sword Serpent: 103 Mercies Dragon Damnation and King, coating himself with a flame dragon, counters with his Extra Large Imperial Flaming Wings. As the clash sends a shockwave throughout Onigashima, Zoro emerge victorious. King's sword is broken, and his right wing is ripped apart. As King's consciousness fades as he falls to the mainland, he thinks of his captain. He had thought of Kaido as the prophesied Joy Boy. Thankful for the life Kaido gave to him, he asked his captain to remain the strongest. He also promised that he would never lose so that he can make Kaido the King of the Pirates. Meanwhile, Zoro, too, recalls his vow to become the world's greatest swordsman―a vow he made to Luffy, the man who he declared will become the King of the Pirates.
