Noob Saibot is a video game character and a recurring Antagonist from the Mortal Kombat fighting game series. He debuted as a hidden character in Mortal Kombat II (1993), although the later game Mortal Kombat: Deception (2004) established his true identity as that of the original Sub-Zero (and the elder brother of the second one) from the first Mortal Kombat, who was killed by his nemesis Scorpion prior to the events of Mortal Kombat II. Saibot's actual birth name, before his death, has never been revealed. It is a note of interest that Noob Saibot is actually Tobias Boon spelled backwards, the two respective creators of the MK series.
