Organization XIII
The events of the game "Kingdom Hearts 3D: Dream Drop Distance" reveal that the true purpose of Organization XIII is for Master Xehanort—the true incarnation of Xemnas' human form—to divide his heart among the bodies of its other members, effectively transforming them into clones of Xehanort so he may recreate the χ-blade using their thirteen hearts of darkness and seven hearts of light. It is also revealed that Nobodies such as those in the Organization are capable of developing hearts of their own over time, but are deceived by Xemnas into thinking they lack hearts so they can cooperate with his plans. Though this agenda is not realized for various reasons, a new Organization XIII is formed from various incarnations of Xehanort from across time, including Xemnas, "Ansem", and members who succeeded in becoming "half Xehanort". This gathering is accomplished by a younger version of Xehanort that is granted the power of time travel by his future self, though they have a final member to recruit as they attempted to make Sora their thirteenth member.
