His concept altogether was just great looking. His moves made sense seeing what his name is referred to. His story was also interesting. He's considered neutral despite that he helps with Onaga. Trying to enforce law and order wherever he goes. Kind of a different character.
I'd like to see him return in a future game, I just don't see him returning for the next game. Seeing how the story is going with that, I don't see how Hotaru, Orderrealm, and any other character associated with these two would fit... Unless I'm wrong and there is a good reason to see these make a return.
I am a huge Sub-Zero fan, been so since the first, however... Deception is actually my least favorite game and my least favorite Sub-Zero story and look. Definitely the look.
