Sektor's Flesh Laboratory

Sektor's Flesh Laboratory is an arena found in the game Mortal Kombat 9 of the Mortal Kombat game franchise.

Overview
The flesh labs have never been truly explained, although one can speculate as what their purpose had been. It is clear, however, that they were designed to create creatures, likely to do Shang Tsung's bidding. Furthermore, they may have been a source of limitless souls for the sorcerer (due to his rapid ageing, he must devour souls to maintain his youth). Thus, it can be concluded that the labs were a source of both, minions for the evil sorcerer and a way of maintaining his youth when he needed to. This privilege may have been extended to Shao Kahn.

The only known characters ever to emerge from the lab to fight in Mortal Kombat were Meat (who was originally a secret skin in Mortal Kombat 4 and was later transformed into an official character in Mortal Kombat: Armageddon), Mileena (confirmed in the second portion of her biography concerning the MK 9 video game) and Skarlet (an enforcer of Shao Kahn created by mixing warrior blood and sorcery).

In an alternate timeline of our world events, a possible outcome led to Reptile turning against Shao Kahn and slaying him. Afterwards, he forced Shang Tsung to use Sektor's Flesh Labs to restore the Raptor race. After many agonising attempts, he succeeded in creating the broodlings that were loyal to Reptile and eventually they stormed Outworld; slaying every Tarkatan, Shokan, and Centaur who stood in Reptile's way.

Trivia

 * In Mortal Kombat VS DC Universe, Shang Tsung's ending indicates that the sorcerer was both impressed and angered by Captain Marvel defeating him. Using his magic within the flesh laboratory where he tortures his victims, he mixed the blood on a torn piece of Captain Marvel's cape with that of a Tarkatan warrior, creating a horrific race of Super-Tarkatan that appears before him and his concubines. They would forever be loyal to Shang Tsung. These creatures appeared somewhat similar in appearance to Dark Kahn.
