The Bo'sun is a minor antagonist in Pirates of the Caribbean: Curse of the Black Pearl, serving as Captain Barbossa's boatswain (hence the name) and first mate. Humorless and bloodthirsty, the Bo'sun inspires fear in both his enemies and his crewmates. Only Barbossa is able to keep him in line, though they have butted heads in the past. He appears alongside Barbossa and the rest of the motly crew in Disney Heroes vs Villains.
