Ok, so my friend AJ pop chatted me on FB today and he has this theory. I want you guys to tell me what you think.

 

"my theory is that Ansem, the one you fought in KH1 is actually Terra"

 

"I have this gut feeling that terra becoming possessed is the birth of ansem hence the name birth by sleep.

Im thinking that when Terra becomes possessed, he loses his heart, gives birth to Ansem (who is terras heartless) and in KH2 when Ansem the wise talks about his assistant Xenenort, thats actually Terra"

 

"because think about it,in KH1 you learn that ansem is a heartless. We wonder "well who is he before the heartless?" in KH2 we learn that ansem is actually Xenenort. and the boss of KH2 is his nobody. Then BBS comes out and we figure out the truth on who Xehenort really is. and im sure you thought that same thing. "Wait this looks NOTHING like the image of xehenort in KH2 its not some old bald guy then Terra becomes possessed and boom, problem solved"

 

 

Sorry if it looks weird, I just copy and pasted what he said from the FB pop chat lol. Let me know your thoughts!

I say Xemnas leans more with this and Ansem leans over more to Xehanort. Ansem blabs a lot about darkness like Master Xehanort. Xemnas looks more and remember the little thing with Aqua'a armor?

I think Ansem SoD is more Xehanort than Terra, but Xemnas is more Terra than Xehanort (appearance doesn't counts ).

 

Terra's body is still inside his armor, so Ansem SoD isn't his heartless, but apprentice Xehanort's, when he was conducting experiments with hearts and when he became a Nobody.

 

And Ansem SoD's appearance is similar to young Master Xehanort.

I apologize, but Terra's body is not in his armor. Basically Terra is like Alfonz Elric.

The name 'Birth By Sleep' was meant to show a sort of revelation for each character, "their own birth by sleep".

Although, I think it generally refers to Ventus falling asleep and awakening Sora's powers.
