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.
This is the list of all finishers (fatalities, babality, and stage fatality) for Sub-Zero.
All of these moves can be unlocked and added to your moves list by performing them in either Arcade Mode or Versus Mode.
