Straw Hat Pirates (麦わらの海賊団)
Straw Hat Pirates is Monkey D. Luffy's pirate crew, named after Luffy's trademark straw hat. While it's a small group numbering only seven, the Straw Hat Pirates are formidable in battle. The crew is captained by Luffy, and Roronoa Zoro serves as the first mate. Although these are their official titles, the Straw Hat's are far from having a clear hierarchical structure. The members generally have equal rights and sometimes even team up to outrank the captain himself when there is strong disagreement.
The tightly knit group exhibits qualities of friendship and brotherhood missing from many other groups that were formed by alliances of people seeking to pillage. Their family-like makeup is a result of the care the captain has for each of his crew members.
Although the fighting skill of each member of the crew varies greatly, the crew members can all handle themselves in the fight. So far the crew has a captain, a first mate/swordsman, a navigator/second mate ( Nami), a sharpshooter ( Usopp), a cook ( Sanji), a doctor ( Chopper) and an archeologist ( Nico Robin). They are currently ( 419+, enies lobby) on the look out for a shipwright, and it is popular belief that one of either Cutty Flam / Franky or Paulie will join after the arcs completion.
The Straw hat's ship is a little caravel named Going Merry and is treated as another crew member and important friend.
