Like most inhabitants of the realms of Mortal Kombat, Outworlders look like humans, but they seem to have a greater talent for magic, and live much longer. Though they dislike their rulers, each of them have their own schemes to attain more power and influence. Known Outworlders include Master Bo' Rai Cho, Li Mei, General Reiko, and Shao Kahn the Konqueror. The Masked Guards and Shadow Priests are also presumed to be Outworlders.
Most Outworlders who are not evil or dangerous, hold on their immortal truth about the independence of their realm in spite of them being trapped in a state of despotism, chaos and war, "This realm is in a constant state of upheaval. Evil rulers come and go, but the spirit of the people will never be extinguished."
