One Piece: Dai Gekisen Tokushuu! Hangeki Doumei vs. Big Mom

On Onigashima, the alliance fighting to free Wano is pushed to its limits as Big Mom joins the battle beside Kaidou. Luffy, Law, Kid, Zoro, and Killer confront the two Emperors on the rooftop while their allies struggle across the island against overwhelming forces.

The clash highlights how the scattered resistance begins turning defense into a counterattack. Through coordinated gambits, stubborn endurance, and increasingly powerful techniques, the fighters search for any opening that might break Big Mom's seemingly unstoppable momentum and keep Wano's rebellion alive.
