Nobodies are creatures without hearts. They are leftovers "born" in the in-between realm, and exist as the body and soul of people who lost their hearts to darkness. As they lack hearts to possess light or darkness,they are nothing, according to the cosmology of the Kingdom Hearts universe, but still exist. Unlike Heartless, Nobodies are able to attack with definite planning. Dusk is the most common type of Nobody. Other Nobodies include Twilight Thorn, Creeper, Samurai, and multiple kinds of Nobody ships. The members of Organization XIII, being the most powerful Nobodies because of the strong hearts they had when they were "whole," kept human form while weaker ones assumed malformed, inhuman forms. Most of the members of the Organization tend to control one type of Nobody, usually suited to their fighting style.
