The Netherrealm is one of the many locations in LEGO Dimensions 2: The Rise of Enoch, from the Mortal Kombat franchise.
The Netherrealm is a realm in the Mortal Kombat series. The Netherrealm is comparable to the Underworld, also known as Hell, in religions and mythologies. It seems to resemble an eternally aflame "continent", containing many volcanic fields and lava pits. The area is also spelled Netherealm, as confirmed in the bios and endings for Mortal Kombat Gold and Mortal Kombat: Deadly Alliance.
