A Battle to Defend Zou - Luffy and Zunesha!

As cannon fire batters Zunesha's leg and Zou pitches violently, Luffy and Momonosuke are wracked by a deafening voice in their heads. Momonosuke recognizes it as the elephant speaking to him and perceives that Jack and the Beasts Pirates are the source of the attack. While the Musketeers and Guardians rush to confront the enemy at sea, Zunesha suffers a crippling hit.

The beast tells Momonosuke it was once sentenced to wander the oceans forever and may not retaliate against Jack without a direct order, then asks him to give one. Momonosuke commands Zunesha to strike, and the elephant wipes out the entire fleet with a single sweep of its trunk.

During the quake, Franky catches a falling building before it crushes Tristan, Zoro slices apart toppling trees, and Raizo pins the debris with shuriken so it cannot bounce onto the minks. Collapsing in pain, Momonosuke receives a vision of Jack's bombardment and reveals the cause, sending the mink squads racing to their ships. Zunesha warns that if it falls, everyone aboard perishes, then begs for the order as its front left leg buckles. Steadying himself, Momonosuke shouts the command across the island; Zunesha steps forward, raises a massive wave, and smashes Jack's ships, shattering his mask and hurling him into the sea before resuming its endless walk.

Bariete races off to spread the news, and Zou steadies. Usopp, learning Jack is a Devil Fruit user who fell into the water, is reassured by Nekomamushi that he likely drowned. Nekomamushi still wants to learn how Jack reached Zou twice, fearing the island remains exposed. On a distant snowy island, Kaidou takes a call from Scratchmen Apoo, who reports that all contact with Jack's fleet is lost.

Anime-original additions include Franky rescuing Tristan, Zoro and Raizo saving minks from a falling tree, and Usopp voicing relief over Jack's apparent death. The adaptation depicts Zunesha swinging its trunk twice, first to launch the fleet skyward and then to crush it. The episode falls within the Zou Arc.
