Murtogg and Mullroy are major characters in the Pirates of the Caribbean series. They are two dimwitted soldiers who are assigned to guard any ship in Port Royal from pirates, although they tend to get distracted easily. In Curse of the Black Pearl, they mention "a ship with black sails that's crewed by the damned and captained by a man so evil that Hell itself spat him back out." Their conversation has foreshadowed the presence of the Black Pearl, Barbossa, and his crew. When Elizabeth Swann got kidnapped, they were part of her rescue team.
In At World's End, they were guarding the chest containing the heart of Davy Jones, but Jack Sparrow was able to take the chest when the two were bickering. After the film's climax, the two joined the crew of the Black Pearl.
