Dark Kahn is a boss from the Mortal Kombat series of fighting games. He debuted as the main antagonist of Mortal Kombat vs. DC Universe and is the game's sole original character (as the fusion of Shao Kahn and Darkseid).
Dark Kahn is a monstrous being of pure Rage created from the accidental merging of Darkseid and Shao Kahn. For the entirety of the storyline, Dark Kahn hides within the merging of Apokolips and Outworld, influencing the DC superheroes, villains and kombatants to fight amongst one another to further fuel the chaos. Dark Kahn does not appear until the final chapter of both sides where he has lured all participants to fight amongst one another until Shang Tsung, Raiden, Superman and Batman are left standing from the midst. The god of thunder and the Man of Steel chase to his tower, which has become a merger of Shao Kahn's Palace and Darkseid's Palace where he tricks them into fighting each other. Eventually, the two are able to break free from his influence and channel his own rage against him, causing his destruction, and Shao Kahn and Darkseid to exist separately (although in each others universe, with a temporary loss of powers). The kombatants deal with Darkseid and send him to the Netherrealm while Shao Kahn becomes trapped in a fragmented Phantom Zone.
Being a fusion of two powerful beings from two separate universes, Dark Kahn is already exceedingly powerful; enough that his own existence threatens the galaxy. Though he posseses both Shao Kahn's brute strength and sorcery, and Darkseid's Omega Force, his primary ability is his Rage, which Captain Marvel refers to as "kombat rage." He is able to infect anyone with this spiritual influence which causes them to fight with an unquenchable bloodlust against both friend and foe. Though they appear to have a degree of conscious control over themselves, they will always perceive their friends to be their deadliest enemies. A telltale sign is the change in their voice, and their glowing yellow eyes. Though the influence is powerful, it can still be conquered.
