Nako

Dr. Nako (Dr. ナコー) is a doctor from Cocoyasi Village.

Appearance
He wears a bandanna with a red cross, a common symbol for medical personnel (which is edited out in the 4Kids dub) and sunglasses.

Personality
He seems to be willing to help others, as he is a doctor, and is probably brave, as he joined the others to try and defeat Arlong, even though he knew he was going to die. He seems a bit grumpy, as he was dumbfounded and angry that Luffy did not have a doctor in his crew to treat any serious wounds that they had, such as the wounds of Zoro. He is otherwise a good doctor and very caring of Nami.

Arlong Arc
He plays a major role in the flashback, while he plays a minor role in the present.

He aids the crowd in fighting the Arlong Pirates and later tends the wounds of Zoro, Luffy, Yosaku, and Johnny. Nako grumbled about the crew having no doctor which gave Luffy an idea to find a doctor of their own. He then put the pinwheel tattoo on Nami's left arm to cover her stab scars.

Two Years Later
After the timeskip, Nako is seen with Nojiko, Chabo, and Genzo, watching them carry tangerines.
