ok know i dont kno if im rite or not but its just something i got a strong feeling about. Know we all kno that the Orginzation is made up of shells from people with strong hearts that once lost there heart. For example: Sora's shell is Roxas, Kiari's shell is Namine but noone said anything about riku cause he also lost his heart and we also said that Saix has some sort of connection with riku. Well could it be a strong possibility that Saix is riku's shell but looks nothing like him?
Heres a pic of Saix
