If there's one character design that screams Mortal Kombat, it's the masked ninja. Daniel Pesina, one actor clad in an iconic costume received multiple palette swaps to be recolored and repurposed as Ermac, Smoke, Scorpion, Reptile – the list goes on and on. But we all know that Sub Zero came first. The blue-clad Chinese ninja warrior with a heart so cold made his debut in the first game and is the only character to be playable in every single installment of the series. A secret operative for the Lin Kuei clan, Sub-Zero's people are descended from Cryomancers, demons who could wield the power of cold for various effects. One thing that's lost in the mythos of the games is that Sub-Zero was actually two different people – in the first Mortal Kombat, he was killed by Scorpion and replaced in the following games by his younger brother, who took up the frosty mantle. But nobody stays dead for long in MK, so look for Sub-Zero elder to show up later on this list... as someone else.
