Smoke

Smoke is a ninja that was transformed into a cyborg and a villain from the Mortal Kombat series of fighting games.

History
Smoke was a member of the Lin Kuei Clan and a close frined of the younger Sub-Zero. The pair went on a mision to Outworld together to kill Shang Tsung, but failed. Upon their return, they disocvered that the Lin Kuei were transforming into their best warriors into cyborgs and had already done so to Sektor and Cyrax. The two attempted to escape the process, but though Sub-Zero escaped, Smoke was not so fortunate. He was transformed into a cyborg and programmed to hunt down his former friend. Smoke's lot in life continued to worsen with the invasion of Shao Kahn. After Sub-Zero made him realize he still had a soul and that he was one of Raiden's chosen warriors, Smoke was captured and rendered inert by Shao Kahn's forces and locked away in the bowels of one of the tyrant's fortresses.

Many years later, Smoke was discovered by Noob Saibot, who reactivated and reprogrammed the cyborg as his servant, so he could use him as the template for a new army of cyber demons. As they left the fortress, Smoke and Saibot were both aware of Sub-Zero and Sareena following them and eventually attacked the ice ninja. However they were stopped by Sareena.

Later, during Mortal Kombat Armageddon, Smoke helped Noob Saibot stage a siege on the Lin Kuei temple, using his powers to transform Lin Kuei ninjas into shadow warriors. However he is defeated by Taven.

In his Armageddon ending, his nanobots grow and multiple at an alarming rate, so much so that they are able envelop all of Edenia, transforming it into place of writhing grey material that calls itself Smoke.
