Battle Smasher

The Battle Smasher is a prosthetic right arm belonging to Zephyr.

Appearance and Design
The Battle Smasher is a gigantic mechanical arm with three-pronged fingers, big enough to hold a full-grown person, a Gatling-gun design for the wrist and forearm on the outside portion, in which the inside is a giant cannon barrel, held together by large bolts at the wrist. The arm is connected to Zephyr's right arm from his elbow, and an additional artificial upper forearm connected to his shoulder, and held together by two mast rigging around his chest for further support. It can only be removed with a special key. Inside the gigantic hand, there is actually a relatively normal, mechanical prosthetic hand.

After Zephyr's final battle with Monkey D. Luffy, the young pirate left a fist-sized dent on one of the fingers.

Capabilities
Zephyr used the Battle Smasher as a powerful bludgeoning weapon; being imbedded with Kairoseki, it was effective for combating against Devil Fruit users, especially against Logia-class, and was large enough to actually hold a full-grown person, effectively sealing their powers and restraining them in one move. Inside the Smasher is a powerful cannon and a machine gun turret. Since it is made of Kairoseki, the device is virtually as hard as diamonds, thus providing an excellent defense. This is shown by not only enduring the strain of its own extremely powerful attacks, but also being used to endure several powerful explosions and attacks throughout the movie.

Due to the strain of the mechanism and Zephyr's old age, he had to take some sort of steroid-like medicine in the form of an inhaler in order to wield it.

Named attacks

 * Smash Buster (スマッシュバスター): Zephyr fires a big bullet at point blank range, which causes a huge explosion. It is able to throw away Borsalino.
 * Smash Blaster (スマッシュブラスター): A long-ranged version of Smash Buster.
 * Smash Tornado (スマッシュトルネード): Zephyr shoots on the ground, causing a big explosion of dust which sends the opponent flying into the air. He then he shoots a rapid sequence of bullets similar to a Gatling gun at the airborne opponent.

Acquisition


When Zephyr was 65 years old, a very powerful pirate cut off his right arm during a brutal battle that left only him, Ain, and Binz alive when all of their other new recruits were killed. The Marine scientists then built the Smasher to replace that severed arm, which took five years to complete, as Zephyr did not receive his arm until age 70. He took the arm with him when he resigned from his position as a Marine instructor and formed his Neo Marines.

One Piece Film Z


Zephyr uses it as a major weapon during almost all the events of One Piece Film: Z, from battling against Marine soldiers and the Straw Hat Pirates to breaking down the security door to the Dyna Stones storage room, until the fight against Luffy, where the pirate managed to leave a fist-sized dent in it. After this, it starts to break down and Zephyr let it fall on the ground. Later, when Admiral Borsalino and his platoon killed Zephyr, the Battle Smasher was recovered by Ain and Binz who use it to make Zephyr's grave marker.
