Birth by Sleep Unbirths= Hearts?

I was thinking about Unbirths when a thought occured to me:

What if Unbirths ARE hearts themselves? Xehanort's Heartless says all Hearts are born in darkness, so maybe Unbirths are hearts in their purest form, before they were given a body, but only the hearts that gave into the darkness they were born from?

 

Hmm, I guess that theory could work, going by what Xehanorts heartless said. Although I actually have no information on the unbirths as of yet so I wouldn't know.

 

Actually, Heartless are hearts.

When someones heart gives into the darkness, the body and soul become a nobody and the heart becomes a Heartless, as the various reports have told us. The names are confusing, but technically it is the Nobodies who are heartless and the Heartless who have no-bodies. :/gasp:

I don't, however, know what an Unbirth is.

 

I think, contraversially, that Unbirths are what Xion is, although, I'm not sure how to explain it in words.

 

maybe they are replicas
and the ds is vens replica(or the ds is the replica of ven)
mx made something with vens heart to create the ds

 

Well, I suppose this could be true. But when you kill them, they don't seem to shoot off a heart like heartless do.

 

So why don't they exist anymore?

 

I'm thinking that Unbirths are those born without memories.
Since the prefix "un" means reverse of something. so reverse birth.
So maybe unbirths are people, etc. who have had all of their memories taken away from them, and possibly even their physical characteristics leaving them to be running on nothing but instinct.

 

Which if that was the case, would lead people to believe that they are emotionless like nobodies are. Maybe they are one if the most corrupt things that can be manifested from someone who has let in so much darkness.

 

Well, maybe they are beings created only from peoples memories, like Xion, as someone earlier said. Although that still wouldn't explain the name 'unbirth'. I guess we'll just have to wait and see.
