Xemnas is the nobody of Xehanort, and the founding member of Organization XIII. Because of possessing the highest-ranking status among the fellow members of the Organization, he is referred to as "The Superior". Xemnas harnesses the element of Nothingness with his weapons known as the Ethereal Blades. Xemnas has command over the Sorcerer Nobodies. For more detailed information on Xemnas, please visit the link found below.
Xemnas looked like Terra from Kingdom Hearts: Birth by Sleep when Xemnas took over Terra's body.
Very complicated. His true name is essentially Xemnas. But, if you mean as a human, he took the name of Ansem, but his true name was Xehanort.
When you fight Xemnas Sora will get captured at some point and Xemnas will drain his HP. You'll have to be Riku to save him.
i think that sora would beat any body's butt in anything that he did (maybe even riku) and i think xemnas and Darth Vader wouldn't even fight cuz it would be all like... Darth"xemnas i.. am... your father..." xemnas" NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO..... but you... you killed my mother.." Darth.."ummm.. no that was my twin brother"xemnas"o.. DADDYY!!!!"
Xehanort
"Xemnas" is "Ansem X", following the trends in all Organization XIII's nobodies' names (ex. Axel = Lea X, Roxas = Sora X, etc.), shows that Xemnas is "Ansem"'s nobody. This is the "Ansem' from the first game, NOT Ansem the Wise. Fangirls often reverse the letters in "Xemnas" to spell "mansex" instead of "Ansem X".
In Kingdom Hearts 358/2 Days gameplay, Xemnas floats across the ground. This isn't to say that Xemnas doesn't walk at all; he just doesn't walk when you play as him in Mission Mode.
Xemnas was using them in a way because he could use the power of Kingdom Hearts for his own good but the Nobodies could also have gained their hearts from it so Xemnas was partly lying.
If Xemnas continued existing, he'd release Kingdom Hearts, and everyone would disappear because a heart can't be shared.
Xehanort
in kingdom hearts? about..... actually, he has no age.
There is no possible way of finding Xemnas in kingdom hearts. You are only able of finding him in kingdom hearts 2, which he is the last boss in the game.
