A Nobody is an empty shell of both Body and Soul that which has been left behind after a person with a strong will and heart (whether good or evil) loses his or her heart to the Darkness. It acts with a will of its own and seems to have feelings, but that is nothing more than a ruse. Unlike Heartless, Nobodies function in a higher manner. They can think and plan, and they are working towards a goal (which is to create Kingdom Hearts from the hearts of people and Heartless that fell to Sora's Keyblade). Nobodies do not truly exist at all.
