Xemnas History
In the Kingdom Hearts universe, when one falls to the darkness and loses their heart, they become a dark creature called a Heartless. On certain occasions, however, if a being of strong will becomes a Heartless, the body left behind will be given a life of its own, becoming a Nobody. The Nobodies were led by a shadowy group known as Organization XIII, and the Organization was led by Xemnas.

The Nobody of an evil man named Xehanort, Xemnas sought to open Kingdom Hearts, the heart of all existence, in order to grant his followers hearts of their own. To accomplish this, he manipulated the Keyblade bearer Sora into destroying the Heartless, allowing the Organization to use the hearts that were left behind. Xemnas' schemes caused chaos throughout the worlds, and Sora eventually confronted Xemnas, apparently slaying him. However, Xemnas somehow survived, and Organization XIII may be back and more diabolical than ever before.
