n the Mortal Kombat universe, Noob Saibot is a wraith from the Netherealm who was the original Sub-Zero and brother to the younger Sub-Zero. He was killed by Scorpion, in revenge for killing him in cold blood. A heartless, coldblooded assassin, Noob Saibot had to earn his place in the Netherrealm and became a deadly force to be reckoned with. In the ending of Mortal Kombat: Deception, it is shown he is willing to kill even his own brother. Again, as seen in Deception, he has partnered with his brother's old ally, Smoke.
