ok so youve heard vanitas might be a chick and vanitas is xion now. my theory is somewhere along those lines but has a little more proof then the black hair of vanitas. in days when xigbar sees xion as ven is strange right? thats because of the obvious ties between sora roxas and ven now heres the theory, roxas and axel see xion as vanitas because of thier memories like xigbar sees xion as ven. now before you shoot me down saying stuff like how come the other org members don't see her as vanitas then? ive already explained her looks are based on your memory. and in the jump trailer you hear ansem the wise talk about the world be covered in darkness and being saved by a boy with a keyblade and he is able to connect his heart with others and i believe that is sora because in kh1 his heart was connected with kairis and i believe its connected with more people such as vanitas and ven.so thats why xion looks like someone who is connected to sora as long as the person has met that person connected to sora
