Gauge was a human male stormtrooper of the First Order who served as a lieutenant. During the First Order-Resistance War, Lieutenant Gauge operated on Batuu, serving as the leader of stormtroopers there. Gauge's role was to run a First Order re-education facility, with the purpose of kidnapping and brainwashing Batuuans to force them to fight for the First Order. To Gauge, the facility was a way to instill the First Order's ideals of order, which he considered real freedom, in the local population and continue the regime's legacy. After the bartender Seezelslak was kidnapped, a droid repair technician rescued him. The technician killed Gauge and destroyed the facility.
