Darkseid attempted to conquer Earth, but was foiled by Superman. Attempting to retreat back to Apokolips via a boom tube, Darkseid was hit by Superman's heat vision so he would be too wounded to return soon. Unfortunately, this happened at the same time that Raiden was zapping Shao Kahn with lightning as he was attempting to leave Earthrealm. The resulting energy caused the portals the link and fuse Darkseid with Shao Kahn to create Dark Kahn. Darkseid and Shao Kahn's consciousness did not seem to have any control over their shared body, only being concerned with senseless violence.
When Dark Kahn was destroyed, Darkseid ended up in the Mortal Kombat universe by accident. He was left chained in the Netherrealm. However, Shang Soong made the mistake of attempting to steal his soul for power; Darkseid reversed the spell and took the wizard's. Restored to full strength, Darkseid gained a minion in the weakened wizard.

- Darkseid was voiced by Perry Brown.
- Darkseid appears in Netherrealm's Mortal Kombat 11 as a DLC Skin for the character Geras.
