Kotal K'etz was emperor to the realm of Osh-Tekk. The Osh-Tekk were a powerful and rich race and didnt know the meaning of defeat. That changed when their realm was invaded by the Emperor of Outworld, Shao Kahn, and his Champion, Goro. Seeing how easily his warriors were being defeated, Kotal K'etz swore allegiance to Shao Kahn in exchange for sparing them. Shao Kahn agreed to spare the inhabitants of Osh-Tek and allowed K'etz to keep his realm's sacred treasure, the Portal Stone.

When Ke'tz son questioned his father over these decisions, Kotal K'etz had his son, Kotal Kahn, enter Earthrealm using the Portal Stone in order to fulfill the rite of the Realmwalk to prove worthy of inheriting K'etz helm and the rite to rule. Upon Kotal's return some untold amount of years later, K'etz noted that while Kotal had grown stronger, he was nonetheless disappointed for failing to become a wise emperor and had doomed the Earthrealm tribe he ruled by teaching them the blood drinking ways of the Osh-Tek. K'etz demanded the return of the Portal Stone from Kotal, but the son struck his father aside and departed.

Years later, Kotal K'etz was one of the most trusted warriors of the new emperor of Outworld, Kotal Kahn. Kotal Kahn granted K'etz Shao Kahns Wrath Hammer and appointed him to find and kill Mileena, Reiko, and Goro. Making his way into the golden desert with Reptile and other warriors, he found Goro. K'etz would notice the sun being blocked out due to the interference of Rain but pressed on, despite his abilities being weakened.

The two warriors entered battle with K'etz hitting Goro in the head with the Wrath Hammer, though this failed to faze the Shokan Prince. As the battle raged on between Kotal K'etz warriors and Mavado with his group of Red Dragon members, Goro gained the upper hand and smashed Kotal K'etz head clean off with the Wrath Hammer.
