An enigma to all who come into contact with him. Ermac's past remains shrouded in mystery. It's believed that he exists as a life force brought together by the souls of extinguished Outworld warriors. Shao Kahn has managed to take possession of these souls and use them to fight on the side of tyranny.
We are Ermac. We are the fusion of the souls of dead warriors created by Shao Kahn to obey him without question. We served as his enforcer for many years, until the Earthrealm warrior Kenshi released us from our bondage and awakened our perception of the worlds that surround us. We are now free to chose our own destiny.
We encountered a fellow warrior spirit who, like Kenshi, understood our suffering. Eager to atone for the atrocities we had commited in Shao Kahn's name, we agreed to help this warrior, Liu Kang, to liberate his allies from the control of the Dragon King. Shao Kahn may be dead, but it seems his essense lives on in this new menace. It is as if they are both manipulated by the very fabrics of the realms.
In an outer chamber of the Dragon King's throne room, Ermac did battle with Liu Kang's enslaved comrades. Ermac was more than a match for the five warriors, but their defeat was not his objective. Liu Kang materialized and, one by one, freed their souls while Ermac occupied the rest.
Eventually, all five were awakened from their enchantment and freed from Onaga's control. Ermac was pleased that his warrior skills could for once bring about a noble outcome. He sensed, however, that an ominous force still shaped the destiny of the realms. It was everywhere. He could feel its influence on Onaga, though the Dragon King was oblivious to its manipulation. Time was running out. Ermac feared the celebration of this latest victory would be short-lived.
