A common thread between all of the members is the "X" that appears within each of their names. As revealed by
Tetsuya Nomura, the director of the game, by removing the "X", the remaining letters form an anagram of the members' original names from when they were humans. For instance, "Roxas" is an anagram of "Sora", and "Xemnas" is an anagram of "Ansem". Xemnas' true name is Xehanort; his name is an anagram of 'no heart' or 'another' with an X added. Xion, being an artificial Replica, had no original name. The name "Xion" came from her label as Replica No.i of the
Replica Project.
Such thoughts made many fans anxious to try and figure out for themselves the rest of the Organization's members' names. 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 that
Xemnas is the one who performs this ceremony. Many have suggested that this isn't true, as Xigbar was the one to find Marluxia and name him, but if one listens to the dialogue between Zexion and Xigbar in
Kingdom Hearts II Final Mix, it is apparent from the way Xigbar does not know how to pronounce Marluxia's name that he was not the one to name him, rather just found him.
