One Piece Episode 1066

The episode begins with Kid, despite his severe injuries, reflecting on various scenes from his life. At the same time, he uses his unique abilities to develop a new weapon and waits for a signal from Law to deploy it.

Elsewhere, Momonosuke desperately tries to alter the trajectory of a floating island. He manages to nudge it slightly, but a sudden, headache-inducing voice interrupts his efforts.

We rewind a bit and see how Kid hurls Big Mom, a massive opponent, into a building with the help of his mechanical bull. His crew members cheer him on. However, Law is frustrated and feels that his contribution is overshadowed by Kid's subsequent, stronger attacks. After some back and forth, Kid agrees to let Law deliver the final blow in future battles.

This argument is abruptly cut short by Big Mom's recovery. Despite her severe injuries, including a broken arm and possible internal damage from Law's previous attack, she manages to heal herself using her devil powers. Law recognizes the gravity of their situation and insists that they must defeat her in this battle, as his energy reserves are dwindling.

As they resume their assault, Big Mom counters by merging the powers of her subordinates—Hera, Napoleon, and Prometheus—into a ghostly entity named Misery. Even in the face of this formidable foe, Law succeeds in toppling a tower onto her.

Throughout the episode, Kid and Law continue their attacks on Big Mom, who eventually reaches her limits. In a final standoff, Law urges Kid to unleash his secret weapon—a massive laser cannon he has secretly constructed. Together, they declare the end of the era led by Big Mom and Kaido.
