Xemnas is the leader of the first Organization XIII and the presumably the first human Nobody. He is callous, cold and emotionless, even for a Nobody. He uses Ethereal Blades as his main weapons, which are reminiscent of lightsabers. Xemnas is great for the most part - a mysterious villain and a challenging boss. However, I dislike how hard his data battle is and how he does not wield a Keyblade when he should be able to wield one. But overall, he is great villain, very manipulative, and I hope to see the re-completed Terra-Xehanort soon.
