In Mortal Kombat 9 (2011 version) for the PS3 and Xbox 360, each character has multiple fatalities that they can perform at the end of the match if your opponent is defeated.
This is the list of all finishers (two fatalities, one babality, and one stage fatality) for Kabal.
These can be unlocked and added to your moves list by performing them in either Arcade Mode or Versus Mode.
