Welcome to Kingdom Hearts Answers. What would you like to know?

It all depends on whether you choose to believe in me or not.

Plot details for the Kingdom Hearts series follow.

Only Ranked individuals, I-VIII are known, plus XIII: Roxas, whom is obviously Sora. The others are as followed (Warning, there may be a bit of a spoiler for those whom have yet to play KH II and KH: Birth by Sleep, be aware):

  1. Xemnas = Ansem (Spoiler Alert whom is actually Xehanort using Terra's body)
  2. Xigbar = Braig
  3. Xaldin = Dilan
  4. Vexen = Even
  5. Lexaeus = Aeleus
  6. Zexion = Ienzo
  7. Saix = Isa
  8. Axel = Lea

Ranked individuals IX-XII have yet to be revealed by Square Enix, but the key to their actual names are obviously found in their artificial, nobody names, given to them by Xemnas.  Timelinesplitter Chaos 00:09, November 13, 2012 (UTC)

I believe these names can be found in the Ansem Reports. - TidusTehSacrificer357 23:01, November 13, 2012 (UTC)
Yeps, I believe they're also noted a bit in KH: 358/2 days, or maybe it's Birth by Sleep I'm thinking about? I dunno.  Timelinesplitter Chaos 01:35, November 14, 2012 (UTC)
OH YEAH! I can't believe I forgot, after you finish a good portion of Dream Drop Distance's story, you also get each of these people's (their actual personas [Lea, Isa, ect.]) profiles in the journal. Just remembered.  Timelinesplitter Chaos 01:37, November 14, 2012 (UTC)
Yeah, Lea is Axel, and Isa is Saix, and apparently they're best friends. Dunno how that works. - TidusTehSacrificer357 01:44, November 14, 2012 (UTC)
Well, they were friends back in Birth by Sleep, that was back when they were whole people of course. You don't really see it too much in Kingdom Hearts II though, however it does elaborate a bit on their connection in 358/2 days, but at that point Axel would just rather be friends with Roxas and Xion.  Timelinesplitter Chaos 01:48, November 14, 2012 (UTC)
In the new game, Lea as a Somebody is attacked by Saix, who is still a nobody (I don't know how that works, having not played the game myself). And, of course, Lea feels really betrayed, which is stupid, but then again, so is half the things Square Enix does these days :P - TidusTehSacrificer357 03:48, November 14, 2012 (UTC)
Agreed, Square Enix comes up with some pretty odd explanations somewhat equal to a 18 year old's fanfiction. Well, not to spoil it, but I'm going to anyways, lol (Spoiler Alert): Saix is taken by Young Xehanort to the Castle That Never Was, with the other gathered "Neo Organization XIII", Master Xehanort then places a shard of his heart within these representatives, Saix included, Saix was basically a doll with no heart, along with Xigbar.  Timelinesplitter Chaos 13:52, November 14, 2012 (UTC)
