The coolest of the mortal kombat ninja's. He's a great chractor if you can master his moves to just be repetitive and piss people off by getting flawless victories using near-unblockable sets of moves.
Freeze, slide

Is a Mortal Kombat ninja. His uniform is blue. Rival of Scorpion, this ninja uses the element of ice. He competed with Scorpion in MK1 for the cooler design... But they were nearly the same... Still, he's a classic, and what would Mortal Kombat be without him? He was re-invented in MK3 with a whole new look(without mask), which was also embellished in Deadly Alliance... A great character with some of the most memorable moves ever!
Sub Zero freezes Scorpion and he will break him.

A MK player dude who pwns the fuck out of everyone with his ice blast and ice shower and to a lesser extent his ice replica.. And certainly not his fucking gay slide move but that doesn't matter because he pwns anyway.

SubZero is a more extreem version of the word 'cool'.
As in:

MrA: Wow! This gift is cool!
MrB: It's not just cool, it's SubZero!
