In Mortal Kombat 9 (2011 version) for the PS3 and Xbox 360, each character has multiple fatalities that can be performed at the end of the match if your opponent is defeated.
This is the list of fatalities, and the babality and stage fatality for Cyber 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.
