When I was replaying KH2 the other day, I noticed something. Right before the 1,000 Heartless Challange, all the Heartless stopped, then Xemnas appeared. and as soon as Xemnas went away, the Heartless started attacking. Saix also proved to be controling the Heartless. Every time he snapped, Heartless would appear. He said the Heartless aly with the strongest. So, since Organization XIII has control over all Nobodies, they are very strong. So, this makes them able to cotrol most of the Heartless. So, basicaly, they have control over almost all of the darkness.
