Nobodies

The Nobodies are one of the main enemies in Kingdom Hearts II. They are stronger and smarter than their counterparts, the Heartless. Like the Heartless, they have no hearts, but pretend to.

They are created when a person with a stronger than usual heart becomes a Heartless. Half of the heart's power becomes a Nobody, while the remaining power becomes a Heartless.

However, if someone with an exeptionally strong heart becomes a Heartless, anobody appeares in human form, with a new name, and knowing their true selves' memories. If the Nobody and true self meet, then the Nobody will fuse, thus returning their power and completing the true self

Notable people who had Nobodies like this were:

Sora, who becomes a Shadow Heartless willingly to save Kairi. Nobody created: Roxas How he becane a Heartless: Stabbed himself in the heart with the Dark Keyblade

Kairi, whose heart took refuge within Sora's own Nobody created: Namine

Xehanort Nobody created: Xemnas How he became a heartless: Cast away his body to explore the darkness
