Smoke

How Smoke joined the Tourney
Smoke debuted in Mortal Kombat II as a hidden character to fight against, along with Noob Saibot and Jade. He was often spotted in the Living Forest stage in which he (along with Jade) peeked out of the trees. Like Reptile when he made his first appearance, he was simply a palette-swap of Scorpion with puffs of smoke surrounding him, but would move extremely fast. He would appear randomly before matches, offering clues that would enable the player to fight him, as Reptile had in the original Mortal Kombat.

Smoke would not have his own storyline until he was featured in Mortal Kombat 3, where he was once again a hidden character, but accessible to players with the use of a code. In this appearance, he would be a tortured human soul trapped in the body of a cyborg. His most defining feature is the fact that he constantly emits smoke. This, combined with his power to teleport and turn invisible, once made him one of the Lin Kuei's top assassins.

In Mortal Kombat (2011), it's revealed that he has long, flowing silver hair that covers his face (although it is shown been blown back in renders and artwork).

After Shinnok's defeat in Earthrealm, Smoke found himself trapped in the Netherrealm. There would've remained, but for the aid of a Spaniard of Shadaloo named Vega. Vega had with the aid of Shadaloo technology would help Smoke fight off Quan Chi's magic that revived him until he would be normal again.
