Xemnas

How Xemnas joined the Tourney
Xemnas, the Superior of the In-Between (狭間の指導者 Hazama no Shidōsha), is the Nobody of Terra-Xehanort. He is the leader of the original Organization XIII, the former ruler of The World That Never Was, and a member of the Real Organization XIII. He serves as the main antagonist of Kingdom Hearts II and as a supporting antagonist in Kingdom Hearts 358/2 Days and Kingdom Hearts 3D: Dream Drop Distance.

Xemnas wields the power of nothingness, and he channels this into his weapons, red blades of energy called Ethereal Blades. He commands the Sorcerer Nobodies. Xemnas, as the Superior, is the founder of Organization XIII and has dominion over all other Nobodies. He is also the Organization's most powerful member, to the point that Marluxia would not dare to face him alongside Larxene and Axel until Sora was also under their control.

Months after his revival, Xemnas plans to manipulate a JSDF captain named Nagato Sakurai to use the Ramon Zero for his purposes.
