Hector Barbossa is a fictional character in the Pirates of the Caribbean film series.
In Pirates of the Caribbean: The Visual Guide, Hector Barbossa is described as being attentive to his appearance, as his elaborate clothing shows. He wears a large ring bearing a lion's head symbol and has purplish blue ostrich plumes and a pheasant feather in his hat (which appears to be important to him, as in the first movie Jack Sparrow interests him in a bargain by saying, "and I'll buy you a hat... a really big one"). His coat buttons are made from recast Incan silver, and his pistol once belonged to a Spanish pirate, won in a duel.
