Drahmin made his debut in Mortal Kombat: Deadly Alliance as one of two Oni, demons of the 5th plane of the Netherealm. He wields an iron club mounted on his right arm. The mask he wears is an artifact called the Face of Kun-Lo. Wearing it allows him to control his rage and fight with his disciplined Netherealm style. Removing it causes him to go into Oni style where he loses his focus and attacks with murderous insanity.

Drahmin was not always a demon. Centuries ago, he was a cruel human warlord in Outworld. For his crimes, he was exiled to the Netherealm where his body and soul were to be tortured for all eternity. As the years dragged on, he fell further and further into insanity until his humanity was lost all together. He eventually accepted his fate and submitted to the power of the Netherealm. He re-emerged from the Netherrealm depths as Drahmin: the Oni Tormentor.
