Water God

The Water God was an unnamed boss from Mortal Kombat Mythologies: Sub-Zero. He was one of four guardian gods assigned by Raiden to guard Shinnok's amulet in the Temple of Elements and acted as the god of water in the Mortal Kombat universe. He possessed the ability to fire jets of water and teleport. He was defeated by the elder Sub-Zero, allowing the ninja access to the fire area of the temple.

In the official Mortal Kombat 4 comic that came with the PC version of said game, the younger Sub-Zero attempts to make peace with the temple guardians, but discovers that they are gone. This could indicate that the Water God was killed by Shinnok during his invasion, an idea further substantiated by Fujin's Mortal Kombat 4 biography screen stating that he and Raiden are among the few surviving Earthrealm gods.
