The Incredible Battle Starts! Luffy vs Luffy - S10.E372

With Zoro risking his own life by distracting Oars before the giant knees him into a wall, Usopp shoots Brook's salt into Oars' mouth with Kuwagata. But Moria's shadow catches the bag and flings it back at Usopp, the bag's contents spilling out before Oars apparently stomped Usopp to death. Oars tries to stomp Nami, only for her to be saved Nightmare Luffy who also saved Usopp at the last second before fighting Oars. While the Rolling Pirates take the unconscious Straw Hats to safety, Nightmare Luffy overpowers Oars to the point of knocking out on Moria with Gum Gum Pistol before sending Oars flying with Gum Gum Storm. The shadows leave Luffy's body, but he appears to have won.
