Mikazuki captains the Big Helmet Pirates and is the only crew member ever named. A swordsman carrying a 36 million berry bounty, he is best remembered for being thrashed by the Galley-La shipwrights after refusing to pay his repair bill at Water 7.
The defining feature is the bulky round helmet on his head, much like the one Kokoro wears except branded with a crescent moon. Beneath it sits the face of a man past middle age, framed by white hair, and his mouth is set with oversized canines that lend him a demonic cast.
Mikazuki proved himself haughty and thankless. Although his vessel had just been fixed, he balked at the bill, complaining the job had taken too long, and rather than settle accounts he drew his blade on the shipwrights to bully his way out of paying.
A bounty of 36 million berries and a track record of crossing the Grand Line to reach Water 7 mark him as no pushover by the standards of the sea's first half, yet none of that mattered against Galley-La. He turned up at Dock 1 once his ship was finished, claimed the price was inflated, and menaced Paulie with his sword while thanking him for the supposed free service. The shipwrights flattened him and his crew on the spot. In anime-only events afterward, rather than being turned in for a reward, Mikazuki was pressed into working off his debt under local loan sharks, who hired him as muscle. Sent to intimidate Aunt during a collection, he fought her until Zoro intervened and blew him away with a single technique.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
