Noob Saibot has made his 2011 Mortal Kombat debut with his own reveal trailer. Noob Saibot and Sub-Zero have a complicated relationship and in the trailer you can hear Noob tell Sub-Zero, "We share blood, but we are not brothers."
Noob Saibot was originally a hidden character in Mortal Kombat 2. In Mortal Kombat: Deception it was revealed that he was the original Sub-Zero who was killed by Scorpion after the first Mortal Kombat. The current Sub-Zero was Noob's younger brother. Confused? Since this Mortal Kombat(2011) isn't a continuation of the past series and is instead a rebirth of the series, Noob and Sub-Zero could have a different background story.
Fun Fact: Noob Saibot is Boon Tobias backwards, the last names of the game's creators, Ed Boon and John Tobias.
Mortal Kombat will be released on April 19 for the Xbox 360 and PS3.
