Tomas Vrbada from Prague was once taken as a boy by an obscure cult who intended to sacrifice him to a demon. As he was burnt alive, he returned as an Enenra and in his rage he slew his killers. After his murder was avenged, he returned to his mortal form, but his memory of the incident was lost and he became unaware of his former life. Eventually, he joined the clan of assassins known as the Lin Kuei, taking the code name "Smoke".
In Smoke's MK 2011 ending, after defeating Shao Kahn, he regains his memory, and remembers his past life as well as the origin of his powers.
