Shao Kahn
Raiden attempts to ally with Quan Chi, offering the souls of the deceased heroes as payment. Quan Chi declines, and reveals he already has possession of the heroes' souls and has turned them into undead "revenants". Quan Chi's words make Raiden realize that "He must win" refers to Shao Kahn himself; should Kahn conquer Earthrealm without victory in Mortal Kombat, the Elder Gods will punish him. Liu Kang, angered by the seemingly pointless deaths of their allies, blames Raiden and goes to attack Shao Kahn alone. Raiden tries to stop Liu Kang, but ends up accidentally killing him when Liu Kang's fire mixes with Raiden's lightning, burning Liu Kang alive. Overcome with guilt, Raiden surrenders to Shao Kahn, at which point, the Elder Gods intervene, imbuing Raiden with their power, which he then uses to defeat and kill Shao Kahn for violating the Mortal Kombat code.
