Naguri

There was once an old pirate who was the captain of the Naguri Pirates and possessed the power of Conqueror's Haki. Twelve years ago, he was living in Gray Terminal and wielded a hammer as his weapon. After being defeated in a battle against the Roger Pirates, he became separated from his crew, but he held no grudge against Roger, as Roger had spared both him and his comrades.

Later, he resolved to set sail again, building a pirate ship in order to search for his lost crew. During this time, he met Luffy D. Monkey and his friends, and taught them about training as pirates. Once the pirate ship was completed, he watched as Luffy D. Monkey and his friends fought against the Great Tiger, promised to have another match with Ace, and then set off on a new journey.
