Attack on a Celestial! Luffy's King Kong Gun of Anger!As the people of Dressrosa cheer for Luffy's return, Doflamingo note that Luffy is at his limit, though Luffy states that he is as well, before being knock down by pillars of string. Doflamingo then attacks Rebecca but she's teleported away by Law. As their battle resumes, Doflamingo relentlessly attacks Luffy with string and takes control of him. Luffy starts to remember that during his training with Rayleigh, he fought a opponent too big for the Kong Gun to work on, and Rayleigh told him that he needed to come up with something else. Luffy realizes that his Kong Gun isn't enough to beat Doflamingo. Doflamingo tells Luffy that they should have all just stayed in his cage and submitted to his manipulation, saying that humans should only live when a divine being like him manipulates them. He says that he would not have had to carry out this massacre if they had not cut their puppet strings, but Luffy has had enough with his talk. Luffy breaks free by activating Fourth Gear and flies into the air, where he declares his disgust to Doflamingo on how he manipulates everyone and makes it feel like he's suffocating, and the Shichibukai says that the people here were born as trash and are meant to be manipulated. Luffy tells him to be quiet as he retracts his forearm, and Doflamingo creates a web to protect himself. Luffy then blows air into his other arm, making the retracted arm even bigger, as he remembers sharing his idea for an improved Kong Gun with Rayleigh, as he prepares to deliver the final blow. Doflamingo creates sixteen string spears imbued with Armament Haki for a final attack of his own. Doflamingo uses his God Thread technique and Luffy unleashes his Gum-Gum King Kong Gun. The clash between Luffy and the strings is powerful enough to cause ripples in the water and be felt by the citizens below, and everyone on Dressrosa cheers Luffy on as he breaks through Doflamingo's attack and defense before hitting Doflamingo himself. The force of the punch sends Doflamingo flying into the ground, with the impact tearing apart the city, and Doflamingo falls down into the underground harbor. Law looks up at Luffy and remembers how Corazon once told him in some countries, there are people who call those with the name of "D.", the sworn enemy of the gods as Doflamingo's shattered glasses fall away and Luffy hovers in the air victorious.
