Organization XIII was comprised of thirteen unusually powerful Nobodies. Led by Xemnas, they sought to claim hearts and become whole; however, in truth, they were pawns of Xehanort in service of the Darkness. As of the events of The Doom of Nobody, a new group of thirteen has begun operating in the place of the original, though their purposes as yet remain unclear.
