In Mortal Kombat (aka Mortal Kombat 9, 2011 version) for the Xbox 360, each character has one babality that they can perform at the end of the match.
Babalities are not purchased from the Krypt or “unlocked” in any fashion that I have found, they are simply hidden and must be performed in Arcade or Versus mode at least once in order to add them to your moves list for that character.
In order to perform a Babality, you must complete the final round without blocking an incoming attack. You can hit the block button, but you simply can’t block an incoming attack on your character.
Here is the complete list of babalities for all characters, and how to perform them.
Check out my other guide for the Mortal Kombat babalities list for PS3.
