What if terranort, Ansem, and Xemnas aren't the same person.  They all have different faces and hair. this is just something i wanted to through out there

Well they're not really

Terranort is Terra's body dominated by Xehanort

Then he becomes Apprentice Xehanort when he loses his memories

Xemnas is the body of Terra with the memories of Xehanort and Terra, and Ansem is Xehanort's heartless

Note that "Terranort" (I've always disliked that name) has been through some style changes in the past, so it's just part of his "growing up", as it were. There's always some subtle changes in the person-to-Nobody transition, but Xehanort's just happened to be more overt.
