Sub-Zero II, formerly known as Tundra. Real name: Kuai Liang. Just as his older brother Bi-Han was, Kuai Liang is a master of harnessing the element of ice and cold, due to their descent from a tribe of Cryomancers. And, just as his brother did, he has taken a liking to removing the heads from his foes. Compared to Bi-Han, though, Kuai Liang is an overall swell guy; he spares opponents unless absolutely necessary, he works with Raiden to fight the Outworld invasion, and he ends up reforming the Lin Kuei into a force of good. Heck, in his first canon appearance (the official MK2 comic), he was dressed in a suit and handed out business cards as part of a PR campaign. FOR A CHINESE GANG OF ASSASSINS.
Despite the costume being so totally '80's, fans seem to really like his MK3 appearance, perhaps due to the fact that it was one of the few physical differences between he and his brother.
Subby-Wubby here's base is the Marvel Universe Gladiator, as noted. His head, believe it or not, is a Green Lantern movie Sinestro. The weird shirt/suspenders or whatever they are, was taken from some extra cloth from a 1/6 project. Left hand used to be Mr. Fantastic's.
