Every member of Organization XIII has been eliminated, except Roxas, who doesn't technically exist after returning to Sora. Here are the causes of elimination:
Xemnas was defeated by Sora and Riku in the Castle that Never Was.
Xigbar was defeated by Sora in the Castle that Never Was.
Xaldin was defeated by Sora at Beast's Castle.
Vexen was defeated by Axel in Castle Oblivion. (Twilight Town card)
Lexaeus was defeated by Riku in Castle Oblivion.
Zexion was defeated by Riku in Castle Oblivion. (Destiny Islands card)
Saix was defeated by Sora in the Castle that Never Was.
Axel destroyed himself to save Sora in Betwixt & Between.
Demyx was defeated by Sora at Hollow Bastion's outskirts.
Luxord was defeated by Sora in the Castle that Never Was.
Marluxia was defeated by Sora in Castle Oblivion.
Larxene was defeated by Sora, Donald, and Goofy in Castle Oblivion.
Roxas betrayed the Organization and returned to Sora.
Xion was eliminated by Roxas, so that Sora's memories could return to Sora.
The eldest member of the Organization is Vexen, the Chilly Academic.
Yep. All of 'em.
Zexion is Organization XIII's Number VI The Cloak Schemer
No...but there is an Axel.
I believe it would be Xion, but if your going by the 13 organization members, it would be Roxas.

In the Kingdom Heart series, Sora would not be considered an Organization member. People may believe this, but it was really his nobody, Roxas, that was a temporary member, before leaving and betraying Organization XIII. Although KH gamers believe that Roxas is a part of Sora, as Sora said, he and Roxas were two completely people. By the end of Kingdom Hearts: Dream Drop Distance, he tells Roxas: "That's what I wanted to tell you. That you deserve, just as much as I do, to be your own person." Besides that, Roxas can be considered as another person, even if his actions and emotions are not his own. So, to summarize, Sora would not be considered an Organization XIII member.
No, Riku was never in Organization XIII. He wore the cloak because he wanted to hide the darkness in his heart.
Organization XIII got its name because it contains thirteen members. Although Xion is known as No. XIV (14), she is not a Nobody; she is a clone that was created from Sora's leaked memories during the events of Kingdom Hearts: Chain of Memories. Xemnas and Saix never considered her a real Organization member. She is more of a puppet meant to absorb the Keyblade's power.-Hope this clears up all of the confusion!-RoxasDive
lexaeus
Zexion has no meaning in the Japanese language as it's origin is entirely English.The understanding behind the Organization XIII nobody names is that they are scrambled forms of their original (non-nobody) names, with the addition of X.Spoilers:As such, "Roxas" is just "Sora" with an X added. Similarly, "Zexion" is actually "Ienzo" with an added X.This applies to all Organization XIII members save for Xion, who is neither a nobody or Organization XIII member.
