"Terex was a human male who served as a stormtrooper designated TK-603 in the Galactic Empire. In the years following the Battle of Jakku, Terex became the leader of a crime syndicate on Kaddak known as the Ranc gang. Still determined to rebuild the Empire, Terex joined the First Order, an Imperial remnant that had relocated to the Unknown Regions. By 34 ABY, Terex had become an agent in the First Order's Security Bureau. During the early phase of the Cold war, Terex fought the Resistance starfighter pilot Poe Dameron and his Black Squadron. Terex also blackmailed the Resistance technician Oddy Muva into spying on Poe and Black Squadron by holding his wife Sowa Chuan captive.
After being bested by Poe on Ovanis and Megalox Beta, Terex embarked on a rogue mission to destroy the Resistance. Terex retook control of the Ranc gang and tried to destroy Poe and the Resistance. However, he was outsmarted by Black Squadron a third time. Following his failed bid to destroy the Resistance, Terex was arrested by Commander Malarus and brought back to the First Order for punishment. While Terex was condemned to the mines, he managed to convince Captain Phasma of his loyalty to the First Order. As a result, he was given a second chance and was fitted with a cyborg construct.
