Organization XIII member #01, Xemnas

Leader of the Organization, Xemnas is a powerful nobody. He believes that hatred and anger are supreme feeling and that Nothingness was eternal. But with Sora and Riku working together, they defeated Xemnas once and for all. What Xemnas didn't know is that there is more to a heart than Anger and Hate and that just because Nothingness was probably eternal, that didn't mean he was. He uses the Nothingness element and has two Aerial Blade weapons. Xemnas is a secret boss in Kingdom Hearts Final Mix. Xemnas' original self was Xehanort, but his name is an arranged form of Ansem X.
