Xaa is a realm mentioned in the Mortal Kombat cartoon series Mortal Kombat: Defenders of the Realm. This realm consists entirely of a jungle-like wilderness with huge spikey rocks, and an empty Asian-styled, temple-like castle at the center of the realm. Not much is known about this strange other dimension, other than it is one of certain realms including Outworld where Raiden has no dominion and is apparently powerless there, as well.
