The Iron Eye Pirates are a pirate crew from North Blue captained by Asaji 'Iron Eye' Dominic. They are minor antagonists in Between the Devil and the Deep Blue Sea and are protagonists in the unpublished side story Sow the Wind.
The Iron Eye Pirates are known for being ruthless and brutal. They have one of the most powerful warships in the world as their main ship, and were strong enough that they only spent six months in Paradise before crossing to the New World. Their strength is such that Portgas D. Noir thought an Admiral was needed to take them out.
Since entering the New World, the Iron Eye Pirates have expanded to a fleet. They have added a subordinate crew manning a modified merchant frigate.
A year before Monkey D. Luffy began his journey as a pirate, the Iron Eye Pirates were formed in North Blue when Asaji Dominic defected from the Marines and stole the Relentless. They quickly gained a reputation for ruthless brutality. In January the following year, the Iron Eye Pirates entered the Grand Line, and crossed over to the New World in mid-July. Shortly after they crossed into the New World, Sengoku assigned Vice Admiral Noir to eliminate them if she encountered them.
One of the Iron Eyes' subordinate crews encountered Noir in a port some months later, though the two sides did not come to blows.
