guys i have a major breakthrough!
from CoM we know that twilight town is where the organization resides and also, it seems nobodies reside there too. and from the trailer i saw with sora explaining who the 13th order were (those who control the nobody) so i think that the 13th order must be nobodies too, just strong ones that take the form of a human. xalidan also said once they acquire kingdom hearts they will become complete beings.

now dont read this next line for my theory because it may be right or wrong, but i dont want to be accused of spoiling.




now from CoM we also know that all organization members have an "x" in their name.

we've come to a conclusion that roxas definetly has a connection with sora. if you take away the x from roxas you get roas. and if you move the letters around you get sora. my theory is roxas is acctually a nobody of sora or something of the sort, perhaps roxas is the heartless form, from when sora turned into a heartless at hollow bastian, thats as far as my theory goes. that roxas=sora's nobody. which would explain why he begins at twilight town.



ok, its safe to read now.

and that final form in battle link...
