"I'm carrying on what you yourself began, and I'm creating a brand new world, one heart at a time." —Xemnas, to Ansem the Wise, on universal domination
As the oldest of the Nobodies, Xemnas wields the power of nothingness, and channels this into his weapons, red blades of energy called Ethereal Blades, which extend from the palms of his hands. He commands the Sorcerer Nobodies.
As the superior, Xemnas is the first member and founder of Organization XIII, with all other Nobodies under his control. He also appears to be the most powerful, so much so that even Marluxia or Axel would not dare to face him. Despite his original name being Xehanort, he uses an anagram of his mentor Ansem the Wise’s name due to Xehanort stealing the name prior to discarding his heart and body.
