Luxord

Luxord, the Gambler of Fate is a member of Organization XIII, the main antagonists of Kingdom Hearts. In the game, Luxord appears during the second visit to the world of Port Royal. Luxord is a Nobody, meaning he is the remains of someone who has lost his heart to the Heartless.

Luxord, on a mission for his superiors to collect hearts from the Heartless, went to the world of Port Royal and stole the cursed Chest of Cortéz to investigate the darkness of men's hearts drawn to the medallions. A couple of pirates who helped him became cursed from them, while Luxord was unaffected (probably because Luxord was a Nobody and had no heart). William Turner went on the HMS Interceptor to make sure the chest was still in its place on Isle de Murtea, but was ambushed by Luxord and his Nobody lackeys, being the sole survivor of their attack.

Elizabeth Swann, concerned about Will's safety, confessed Jack Sparrow, Sora, Donald and Goofy to take her and search for Will, who they eventually found, but were attacked by Luxord, who siced the "Grim Reaper" Heartless on them. Jack, Sora, Donald and Goofy defeated the monster, but Luxord, in possesion of Cortéz's chest, threw several medallions away to his Gambler Nobodies and had his now-immortal Grim Reaper Heartless blow the four off the ship to the Interceptor, who he then used the Black Pearl's cannons to completely destroy.

Luxord also used the chest's powers to curse Jack to his skeleton form, leading him, Sora, Donald and Goofy on a scavenger hunt to find the four medallions that Luxord had given to his lackeys. They accomplished in doing so and defeated the Grim Reaper in Port Royal, to which heart went to Luxord, who warped himself away, having completed his mission.

Luxord was later hunted down and killed by Sora in the World That Never Was.
