Cat, a Nefrian of the male persuasion, functioned as the flight engineer aboard the MG-100 StarFortress SF-17 heavy bomber known as the Cobalt Treasure amidst the Atterra campaign. Subsequently, he assumed the role of flight engineer on the Cobalt Wasp following the illness-induced departure of the bomber's initial flight engineer, who encountered difficulties adapting to Refnu's environment. During the Atterra campaign's second iteration, both Cobalt and Crimson Squadrons found themselves besieged by First Order forces. Cat met his demise when TIE fighters obliterated the Cobalt Wasp.
