Outworlders are the native species that exist in Outworld. Outworlders seem to only be utilized in Shao Kahn armies if they have superior combat abilities, like Reiko, leading to the conclusion that Tarkatans, Shokan, and Centaurs have higher status at least during Shao Kahns control.
Outworlders look human like most sentient species throughout the realms though their are notable differences. Outworlders have an extended lifespan allowing them to live for thousands of years. Outworlders have a natural affinity for magic which manifest in ways benefiting to the user, Bo' Rai Cho's seismic powers being attributed to his large girth.
Personality: Outworlders vary in personality as much as humans do. While the most famous ones are know for their tyrannical ambitions like Shao Kahn, Bo' Rai Cho is a martial arts master working against the chaos that Outworld spreads to other realms. Li Mei is a fighter working to free her village from the Deadly Alliance. Most Outworlders just attempt to survive whoever is ruling them at the time. With constant states of upheaval and turmoil Outwirlders have become very good at preserving their spirit
Outworlders use magic more than technology. While grand cities and Shao Kahns palace are littered across Outworld these were built with similar technology to the ancient Egyptians. Outworlds lack of technology is what makes Earthrealm such a prize in Shao Kahns eyes. Shao Kahns military is they only area to utilize modern weaponry due to Kano and the Black Dragons bartering it for Shao Kahns favor.
Shao Kahn- The most current ruler of Outworld. Shao Kahn is a tyrannical leader using Mortal Kombat and direct conquest to add to his empire. Shao Kahn is noted as the most powerful Outwolrder since the only beings aboe to stand against him are sorcerers (Shang Tsung, Quan Chi), Gods (Raiden, Fujin, Shinnok), Onaga, and Liu Kang.
Bo' Rai Cho- A martial arts master who does not agree with Shao Kahns methods. Bo' Rai Cho is noted for teaching martial arts to people who stand against Outworld such as Liu Kang, Kung Lao, Li Mei, and Shijinko.
Li Mei- Li Mei village was enslaved to build a palace around Shang Tsung's soulando. Li Mei had attacked the enforcers and was noticed by Quan Chi who said that if she won a tournament she would be able to go free. After some training with Shujinko Li Mei was victorious and was then "free" to become a dragon king solider under Quan Chi's control. Li mei was partially spared this fate though she took on some of the Dragon Soldiers characteristics.
General Reiko- A member of the Brotherhood of Shadow, Reiko is noted for his brutality in combat. After Shinnoks failed attempt to conquer Edenina, Reiko ended up serving as Shao Kahns general. Reiko grew to envy Shao Kahn and even wanted to become him. He wields a war hammer just like Kahn and has bee know to where his helmet when Shao Kahn is not around
