Ansem Report 15:
Although I no longer seek ever-lasting darkness, old questions about the heartless (including myself) have resurfaced, and rekindled my interest in the matter.
Further observation of the heartless showed that, when a heart is taken by the heartless, the victim gives off a heart-like apparition before vanishing and becoming a heartless themselves.
Further more, when a heartless is destroyed, a second apparition is emitted. This happens in every test, and can mean only one thing as a person has no more than a single heart: each apparition is only half of the original heart.
This may also explain the ravenous behavior of the heartless. Each heartless would be only one half of the subject's heart, and as it is the nature of the heart, it seeks to be complete. The heartless will take the half similar to that which it has lost, but it cannot bond with it because it is foreign, thus the half is discarded and wasted. This would be the first apparition. The second must be the half that was the heartless itself.
I also have another theory.
A heart that has been lost might retain its human form if it were left intact, as I believe has happened to me. However, I do not possess the tools necessary to test this theory. Until then, I shall simply make due.

AN: Well, what do you think? My first "REAL" fanfiction! Yay!
I need to make something clear… All of the "observations" Ansem apparently made here; I actually saw IN THE GAME! See for yourselves! The first time you visit the Second District, you see that one dude loose his heart, and all through the rest of the game, every heartless you kill turns into a flying heart-thing! The rest is just speculation and creative license... I will be doing more of these fake/fic-reports eventually… sooner or later… definitely absolutely maybe! (yup…) :3
