Vergo

Vergo is a villain from One Piece, and the secondary antagonist of the Punk Hazard Arc. He was one of Donquixote Doflamingo's accomplices, given the task of assisting Caesar Clown. He disguised himself as a Navy officer, commander of Branch G-5. Using his rank, he was able to hide Caesar's operations of testing drugs on kids, telling those children's parents that they should forget about their children, saying they can never be found.

Abilities
Vergo is a skilled martial artist, and is proficient with the ability of Armament Haki, and is also shown to be very fast. His Armament Haki is so great, he's able to turn his entire body to iron. However, this power is still vulnerable to Trafalgar Law's Op-Op powers.
