Nobody

A Nobody is what is left behind by those whose hearts have been consumed by Heartless. The first generic Nobodies are seen in Kingdom Hearts II, although members of Organization XIII and Naminé appeared as early as Kingdom Hearts: Chain of Memories and Kingdom Hearts: Final Mix.

Nature
Nobodies are born when a heart is swallowed by darkness and becomes a Heartless. They are the remaining parts left behind by the heart: the body, giving a Nobody form, and the soul, giving the Nobody life. However, only those with strong wills such as Sora are actually able to continue on as Nobodies. Those with the strongest wills manage to retain human forms with some slight changes to their appearance, while the rest possess malformed, barely humanoid appearances. Therefore, the more humanoid a Nobody, the more powerful it is.

All Nobodies, vanishing from the realm of light upon the loss of the heart, are born in Twilight Town, a world in-between the realms of light and darkness. However, because of this and their lack of hearts, they are shunned by both light and darkness, and do not truly exist.

Thanks to their missing hearts, Nobodies lack emotion. Although, some humanoid Nobodies pretend to possess emotions, fooling others as well as themselves. On the other hand, Nobodies manage to keep their memories of their former lives, but unusual Nobodies lack memories of their former selves.
