Black Arm Zephyr

Zephyr sat on the ground, surrounded by red lava. Explosive Rocks had been planted at intervals, and Luffy's straw hat rested on one of them.

"So you came, brat..." Zephyr paid Luffy no mind. Perhaps someone who had already given up his life had nothing left worth noticing. "The explosions that will destroy the final node have already begun."

"That's not why I came." Luffy's eyes had never left his straw hat. "I just came to get my hat back."

"What does that battered hat mean to you?" Zephyr asked. He saw in Luffy the shadow of an old friend.

"It's a guiding light!" Luffy remembered the promise he had made to Shanks. "It shows me the way to become the King of the Pirates!"

"Hah!" Zephyr gave a scornful laugh. "I can't forgive pirates for having dreams! I'll destroy every sea you've set foot in!"

Zephyr rose and shrugged off his coat, revealing his powerful upper body. "Remember the name of the man who will destroy all evil... Z!"

Zephyr charged at Luffy. The massive weapon in his hand did nothing to slow him down, though Luffy was every bit as fast. They collided head-on. Luffy slammed his fist into Zephyr's Battle Smasher, but Zephyr swung his right arm and sent him flying.

Luffy refused to back down. He used his momentum to kick at Zephyr, only for Zephyr to block with his left hand, coated in Armament Haki. Luffy quickly pulled away.

"Have you stopped caring what happens to you?" Zephyr charged, bringing the Battle Smasher down on Luffy.

Luffy met it with a punch. Seastone kept him from using his powers, so he could only keep punching, taking Zephyr on in the most direct way possible.

"You'll never break my justice!" Zephyr looked at Luffy with contempt.
