Like other Konquest stages, this arena has no Deathtraps or weapons. It is where the undead ninja warrior Scorpion keeps his captive prisoners and also where he fights the warriors he captured and transported them to this fighting arena of his.
At the end of the battle as Scorpion was defeated by the Edenian demi-god, his brother Daegon comes to finish the job himself in order to be the only new Protector god of Edenia. Just as him and Taven were about to fight in Scorpion's Lair, Blaze comes in and stops the fight as he teleports them to the Ruins outside the Pyramid of Argus.

- This is the second appearance of an arena named Scorpion's Lair. The first one was in Ultimate Mortal Kombat 3 which clearly took place in Hell.
