Luxord

How Luxord joined the Tourney
Luxord appears with all of the other Organization members in the confrontation with Sora in Hollow Bastion and stands behind and to the left of Saïx.

Immediately after taunting Sora, the Organization returns to their meeting chamber. In response to talk about making plans for the future, Luxord states his hope for the boy and his intention to lend a hand to determine Sora's fate. This causes Demyx to suggest his own method, much Xigbar's chagrin, and after Xaldin chastises him, Luxord expresses disappointment, realizing that he needs to wait for his fun to begin.

After Saïx returns from the Battle of the 1000 Heartless, Luxord remarks how Sora is unable to stop the Organization's master plan, as events are already in motion. Xaldin tells Luxord that luck might not fall in his favor, and Luxord replies that the fun of gambling is in not knowing the outcome.

Upon making second rounds to the worlds in search of Organization XIII's stronghold, Sora once again allies with Jack Sparrow in Port Royal, where he learns that Will Turner has gone missing while investigating the theft of cursed pirate gold by a man in a black hood. They seek out Will using the Black Pearl, and find him on the Interceptor.

Luxord appears on the Black Pearl as soon as they recover Will, with the cursed gold beside him, and greets Jack Sparrow. He reveals that he is at Port Royal to assess the value of the cursed gold to the Organization, and summons the Grim Reaper Heartless. After the Heartless is thrown overboard, Luxord invokes the right of parley before Jack can get off a shot with his pistol. He agrees to hand over the chest, but takes four medallions while passing it over and gives them to his Gambler Nobodies, who vanish. This reactivates the curse on Jack, as well as placing it on the Grim Reaper.

The Grim Reaper then knocks Sora, Donald, Goofy, and Jack onto the Interceptor, and has the cannons of the Black Pearl destroy the ship. Sora and the others survive and track down the medallions, after which they head to Port Royal and defeat the Grim Reaper, lifting the curse on Jack. Even with Luxord's experiments having failed, he manages to bring the heart that the Grim Reaper was holding to Kingdom Hearts, and promptly flees.

Following Axel's death, Luxord attends the meeting at Where Nothing Gathers to discuss the former's fate after his sacrifice. He belives that Axel came out "a winner" in betting his existence, or lack thereof, on Sora. However, Xigbar and Saïx oppose Luxord's opinion, pointing that his words contradicts the foundation of their existence as Nobodies.

Luxord appears once more in Organization XIII's fortress in The World That Never Was. When Sora, Kairi, Riku, Donald and Goofy enter the area where Luxord waits, Sora walks ahead of the rest. Materializing between Sora and his friends, Luxord uses his cards to remove Sora's allies from the area, and challenges Sora to a game involving time. Luxord fights against Sora, using a variety of tricks and games of luck with his playing cards, but in the end, Sora is able to wear Luxord's time down and defeat him. As Sora readies a finishing blow, Luxord raises his cards to shield himself, but Sora slices through the cards and finishes Luxord off. His last words are "How could you......Roxas?" before fading out.

Returned to life, Luxord found himself on Qo'noS. Searching for game, he spotted the Enterprise NX-01 and its captain, Jonathan Archer. He then set up a gambling fight for the captain and expected one condition; Throw the fight.
