After centuries of Mortal Kombat, Emperor Shao Kahn has finally defeated Raiden and his allies. Faced with extinction, Raiden has one last chance. To undo the Emperor’s victory, he must strike Shao Kahn where he is vulnerable…The Past.

Mortal Kombat vs. DC Universe does not follow chronologically with the other games in the Mortal Kombat series, and is considered an “ultimate-Elseworlds” for DC Universe continuity by story co-writer Jimmy Palmiotti.

Two years after the defeat of Shao Kahn, Shinnok attacks Earthrealm with his army of Netherrealm demons, as well as the Earthrealm warriors who were killed during Kahn’s invasion and are now resurrected as revenants under Quan Chi’s control.
