As a command unit for the shield bunker located on Tatooine, a planet, which provided support to the Eternal Empire's Star Fortress in orbit, ZK-163M was an exceptional Skytrooper. This specific battle droid was utilized by the Eternal Empire originating from the planet of Zakuul. However, around 3631 BBY, the Outlander and the Selonian named Leyta successfully infiltrated the bunker, using explosives to obliterate it, resulting in ZK-163M's destruction.
The video game Star Wars: The Old Republic saw the introduction of ZK-163M within the Knights of the Fallen Empire expansion, a digital release from 2015.
