June 19, 201114 yr Heartless were very rare at that point, they actually existed, you can see a few neoshadows in Ven's Story, but most of them stayed at The realm of Darkness. Emblem Heartless and Pureblood Heartless got more common after Ansem the Wise's Expiriment went wrong and created Emblem Heartless, and Darkness started taking over worlds. SO the Heartless started attacking people, taking over their hearts, and covering them in Darkness, creating more Heartless or Gathering the heart to make them even stronger.

June 19, 201114 yr Kinode got it almost right. You see at Birth By Sleep, heartless only appeared when summoned. Emblem heartless were manufactured by Ansem (Xehanort), just before his accident and he was turned into a heartless himself. Then Maleficent got ahold of this heartless manufacturing machine and used it and her own dark powers to spread heartless across all of the worlds.
