Xehanort

A keyboard master who is obsessed with Kingdom Hearts and obtaining the χ-blade.

Master Xehanort's pursuit of the World's true nature and obsession with the Keyblade War led him to give his heart over to darkness. He tried to forge the χ-blade and trigger another Keyblade War, but three young Keyblade wielders put a stop to him.

Now, he has created a new Organization—the real Organization XIII—and intends to divide his heart among its other twelve members to create thirteen darknesses.
