In the Films
In the films, Davy Jones is the captain of the Flying Dutchman (based on the feared ghost ship of the same name featured in nautical lore), and roams the seas in search of souls to serve upon his vessel for a century. He was previously the lover of Calypso, a "heathen goddess" from which a bad relationship turned him antagonistic. Jones is the legend behind the fictitious Dead Man's Chest, a major aspect of the second film. Jack Sparrow made a deal with him to raise the Black Pearl. Afterward, Jones sought to make Jack a crew member of the Flying Dutchman. Jack refused, so Bootstrap Bill (who also made a deal with Jones) put a symbol on him for Jones's pet, the Kraken, to hunt him and take his soul to Davy Jones's Locker. Jack tricked Will Turner into becoming part of the Flying Dutchman's crew, but he was able to steal the key to the Dead Man's Chest from Jones while he was asleep. Eventually the Kraken swallowed Jack and the Black Pearl, but his heart, which Jack earlier dug up, was taken to Lord Cutler Beckett by James Norrington.

From here, Jones became Beckett's servant, since he possessed the heart and could destroy it if Jones disobeyed him. Eventually he and his crew fought alongside the East India Trading Company against Will, Elizabeth, Barbossa, Gibbs, and other pirates in Jack's crew as the Black Pearl and Flying Dutchman faced off at a maelstrom created by Calypso. During which, Jones dueled Jack, who eventually unlocked the Dead Man's Chest and threatened to stab Jones's heart with his broken sword (earlier snapped in two by Jones with his claw). He stabbed Will in the heart with his sword, twisting the blade. At this, Bootstrap, previously driven insane from his imprisonment in the wall of the ship, returned to his senses and beat up Jones. Before Jones could stab Bootstrap, Will stabbed the heart, with help from Jack, and Jones fell to his death into the maelstrom. As he fell, he whispered his final word: "Calypso". After years of sailing the sea spreading terror, Davy Jones was finally defeated and rejoined with Calypso. Beckett would meet this fate shortly afterwards.
