Nobody Original Names *maybe minor spoilers*

[Tavrobel]

I - Xemnas, Ansem (from Xehanort, stole Ansem's name)
II - Xigbar, Blieg (Braig in the Japanese version)
III - Xaldin, Dilin (Dilan in the Japanese version)
IV - Vexen, Even
V - Lexaeus, Eleus (Elaeus in the Japanese verion)
VI - Zexion, Ienzo
VII - Saïx, none
VIII - Axel, none
IX - Demyx, none
X - Luxord, none
XI - Marluxia, none
XII - Larxene, none
XIII - Roxas, Sora

All other names and justifications are false.

The only other person that could possibly have a name is Saïx, whose original name would be "Increased Attack Speed."

Just a little DotA humor.
