the story mode, Sonya is investigating the dimensional imbalance caused by Shao Kahn and Darkseid's inadvertent fusion into Dark Kahn. After defeating Catwoman, Baraka, Captain Marvel, and Green Lantern, Sonya and Jax return to their base to use a teleportation machine in an attempt to reach the DC Universe. When she finds Jax with Green Lantern, Sonya once again challenges the latter, only to be defeated and imprisoned before she and Jax escape again. When Earthrealm's heroes and Outworld's villains join forces to fight invaders from the DC universe, Sonya reluctantly teams up with Kano to track a foreign energy signal, but they are confronted and defeated by the Joker and Deathstroke.
