Z

Zephyr also know as"Black Arm" Z (黒腕のゼット) is the main antagonist of the One Piece Film Z. He was once a Marine Admiral before his resignation.

Appearance
Z appears as a big and muscular man with short purple hair and a large mechanical right arm connected to the left hip with some mast rigging. He dresses in a Marine-like coat with his Jolly Roger impressed on it and baggy trousers tucked into his boots.

Personality
Not much is known about his personality as the character is not seen yet. However, he appears to hate pirates, as he formed a group to annihilate all pirates.

Abilities and Powers
In a trailer, he is referred to as being the strongest enemy that the Straw Hats have faced yet.

In the past he was a Marine admiral, which means his command over the soldiers within the organization was once the second highest, just underneath the Fleet Admiral. He also had the authority to issue a Buster Call on any island he deemed a threat, and could give that authority to any World Government agent. With his resignation he forfeited such privileges.

Combat-wise, he is able to use Haki, as all Marines with a rank of vice admiral or higher are capable of such a feat. Being an admiral also means he was once crowned as the World Government's greatest military power, being among the strongest individual fighters within the government and Marine organizations of his time.

He has a mechanical arm that is made from sea-stone that is named "smasher".

History
He was a former mento of Akainu, Aokiji and Kizaru. When he was an admiral his wife and sons were killed by pirates. Moreover, a very strong pirate kills all of his men and cuts his arm off. When the government invites this evil pirate to join Shichibukai, Z disappointment towards the goverment led him to leave the Marine.

A group called "Neo Marine" led by Z breaks into a Marine's stronghold and snatches the so-called "Daina Rock". Kizaru appears and says something like "It's been a long time, Zephyr-Sensei. Please put the Daina Rock down" just before attacking him. Z says "I'm pretty sure I've already taught you not to rely too much on your light beams" and fights back. The Rock that Z had stolen bursts into a island-wide explosion. Kizaru does not get injured, while Z gets swallowed by the explosion and is drifted away.

He aims to destroy 3 islands located in the New World called "Endpoint". Those island are covered with magma, and if destroyed the Golden Age of Piracy would end.
