FN-3761 was a stormtrooper serving within the FN Corps of the First Order, identified as a human male. He was stationed at Starkiller Base, where he performed janitorial tasks alongside FN-2187 (later known as Finn). After an infestation was reported in a construction sector, Captain Phasma dispatched FN-3761 and FN-2187 to Deck Nine. There, they were to assist the cleaning crew, which was under the command of Captain Bray.
