Organization XIII
Spoiler Warning!
Organization XIII debuted in Kingdom Hearts: Chain of Memories, then known as simply, "the Organization." In Sora's story, the player was introduced to (in no particular order) Marluxia, Axel, Larxene, and Vexen. In Reverse/Rebirth, Zexion and Lexaeus were added to the cast. The Organization also appeared in Kingdom Hearts II. In this second installment, the player meets (once again, in no particular order) Xigbar, Xaldin, Saïx, Demyx, Luxord, Roxas, the leader Xemnas, and the returning member, Axel.
Organization XIII is a group of thirteen "people" called Nobodies, who have no hearts, nor emotions. Many of them try to hide this fact by pretending that they posses these qualities, fooling others as well as themselves. The Organization yearns to discover the secrets of the heart and fill the empty void inside themselves by gathering hearts to form the great Kingdom Hearts so that they can become full humans again. While each member is aware of their lack of emotions - a fact that makes them feel inadequate - they fill their nonexistance with their favorite passtimes(Xemnas often tells them too fill themselves up with rage and anger). The Kingdom Hearts: Chain of Memories manga contradicts this, saying that they do have emotions, but are plagued by a feeling of uncertainty and emptiness due too not having hearts. This is evidenced in the Kingdom Hearts 2 Manga, which shows Roxas crying moments before fusing with Sora, which is supposed too be impossible if he does not possess emotions.
Origin
Organization XIII was formed by a group of scientists working under a man called Ansem the Wise, the ruler of Radiant Garden, and worked from Ansem's castle, Hollow Bastion. The head of this group was Ansem's apprentice, Xehanort, with the others being Braig, Dilan, Even, Aeleus, and Ienzo. Ansem the Wise began initiating tests about the human heart, focusing mainly on Xehanort, with the hopes of recovering his lost memories. At the urging of Ienzo, he even constructed a massive laboratory in his basement. However, Ansem the Wise soon ceased his experiments, for he feared that going too deep would have grave repercussions, also noting Xehanort's "superhuman" abilities.
However, his six apprentices, still seduced by the desire for knowledge, conducted their own, dangerous, experiments on countless subjects. Eventually, they discovered the beings called Heartless, those that are born from the darkness in a heart and seek others as well. Xehanort, having taken on Ansem's name and writing his findings under it, opened a door he discovered, breaking down the barriers between worlds and allowing travel between them. And when the king named Mickey arrived, the six mens' desire for knowledge eventually caused Xehanort to abandon his body, becoming a Heartless (though he was unusual in that he had a human form and retained his memories), with the other five soon following. Thus, the first six members of Organization XIII were born, and they banished Ansem to a realm of nothingness.
Inner workings
Dress
Each member in the Organization dons the same uniform, regardless of whether they are male or female. The uniform consists of a single black leather hooded cloak that trails down to the ankle. It is plainly adorned with a silver zipper and seemingly pointless silver beaded pull strings for the hood that form a semi-circle in the middle. Not much is known about the under garments of the Organization. It is known however, that they all wear hakama-esque black pants and knee high silver trimmed boots. In addition to this, they all bare black leather gloves of some unknown length, as they disappear under bell shaped sleeves.
Ranking
Ranks within the Organization have little to nothing to do with power. While Xehanort's Nobody, known as Xemnas, is undoubtedly the strongest as well as the leader, the rest fall in a seemingly random order. According to several sources, the member's number (though authority is dependent on other factors) depends on when they joined the Organization. As the group's name describes, there are a total thirteen members. Besides for having a numerical rank, each member also has an assigned title. The only exception to this is Xemnas, who, if anything else, is called "The Superior". The ranks and titles are as follows:
1. Xemnas; "The Superior;" Controlled Sorcerers
2. Xigbar; "The Free Shooter;" Controlled Snipers
3. Xaldin; "The Whirlwind Lancer;" Controlled Dragoons
4. Vexen; "The Chilly Academic"
5. Lexaeus; "The Silent Hero"
6. Zexion; "The Cloaked Schemer"
7. Saïx; "The Lunar Diviner;" Controlled Berserkers
8. Axel; "The Flurry of Dancing Flames;" Controlled Assassins
9. Demyx; "The Melodius Nocturne;" Controlled Dancers
10. Luxord; "The Gambler of Fate;" Controlled Gamblers
11. Marluxia; "The Graceful Assassin"
12. Larxene; "The Savage Nymph"
13. Roxas; "The Key of Destiny;" Controlled Samurai
Each of the titles correspond to whichever element the particular member controls, or the type of weapon they have.
Differences
There are a few major differences between the Nobodies within the Organization and the ones that Sora frequently encounters throughout the game. The average type that Sora fights often have strange features, inhanced speed, metallic skin in shades of white, silver, and blue, and the trademark Nobody symbol (which doubles as the logo for the Organization). The Nobodies that make up the Organization have human forms with limited special powers, revolving around thirteen different elements. One ability shared by all the members is the power to summon an oval, obsidean portal of darkness that leads to the unseen paths of darkness. These portals are known as corridors of darkness. The Organization makes use of the paths to move to and from worlds unseen.
Lesser Nobodies
A few select members of the Organization have control over the other, weaker Nobodies, though this is only shown in Kingdom Hearts II. The members from CoM (a.k.a. "Chain of Memories") may also have had that ability, or rather, would have, had they all survived to the second game. Like their titles, each member's lesser Nobody has some similarity to them. These lesser Nobodies are called Sorcerers, Snipers, Dragoons, Berserkers, Assassins, Dancers, Gamblers, and Samurai. Sorcerer Nobodies are under the command of Xemnas. They float over the ground constantly, possessing a grace much like that of Xemnas, and utilize large cubes of nothingness in several ways. They are the most powerful and rarest of the lesser Nobodies. Sniper Nobodies are controlled by Xigbar and, like him, carry spiky guns that shoot small red crystallized lasers. Dragoon Nobodies are controlled by Xaldin because of his affinity with wind, and possess a singular lance that mirrors the six that he fights with. Berserker Nobodies are under Saïx's power and, as with the previously mentioned lesser Nobodies, hold a weapon identical to that of their master. An observant player will also notice that Berserker Nobodies go through random surges of anger, much like Saïx when he draws upon the power of the moon. Next are the Assasin Nobodies. This group is under Axel's control, capable of becoming a circular form similar to Axel's weapon, hiding away for short periods of time before attacking, and causing powerful explosions. Dancer Nobodies are the most colorful of all the lesser Nobody, featuring bright colors such as orange and pink. They are Demyx's servants and relate to him due to his musical nature. The Gambler Nobodies are under Luxord's rule. Luxord, being a gambler of many things, fights with cards, which they use as well, along with several die. The final of these lesser Nobodies are Samurai, which Roxas controls. While being a seemingly unlikely choice, Samurai wield two broad swords (rather than the typical katana) just as Roxas weilds two Keyblades, Oblivion and Oathkeeper.
Naming
A common thread between all of the members is the "X" that appears within each of their names. As revealed by Tetsura Nomura, the director of the game, by removing the "X", the remaining letters form an anagram of the members' original name from when they were humans. For instance, "Roxas" is an anagram of "Sora", and "Xemnas" is an anagram of "Ansem". Xemnas' other is Xehanort; though he is not a Nobody his name is an anagram of 'no heart' or 'another' with an X added. Such thought made many fans anxious to try and figure out for themselves what the rest of the Organization's members anagrammed out to. Therefore, the members have also become targets of mis-annagraming, primarily being Xemnas and Xigbar. While Kingdom Hearts II: Final Mix has yet to be released, magazine scans show how each of the member's names were decided upon. Appearantly, the name of the Nobodies' "other" appears before them in translucent, rainbow colored font (similar to the one shown at the intro to "The World That Never Was"). Then, an "x" drops down and the letters re-arrange themselves until they form a new name. It is also suggested from these magazine scans that Xemnas is the one who performs this ceremony. This was originally meant to be shown in Kingdom Hearts II, but the idea was discarded as it was found too time consuming.
