Shao Kahn
Shao Kahn and Darkseid are the key villains in the crossover game "Mortal Kombat vs. DC Universe", though both are playable characters. In the game's plot, a defeated Shao Kahn meets with his secret ally, Quan Chi. They are confronted by Raiden, who knocks him into Quan Chi’s portal. This event, along with a parallel one between Superman and Darkseid in the DC Universe, results in the creation of Dark Kahn, who serves as the main antagonist of the game. After Dark Kahn is defeated, Shao Kahn ends up in Darkseid's throne room, where he discovers he has lost his powers before being imprisoned in the Phantom Zone. However, his powers soon came back and he was able to free himself along with everyone else in the Phantom Zone; who pledged their allegiance to him in return.
