Quan Ch's specialized class, upgraded from Imperial Security Trooper and mocked by Donut for its plural.
The sixth-floor recap showed Quan Ch switching from Imperial Security Trooper to Sergeant-at-Arms. Princess Donut pounced on the name, arguing that a one-armed crawler should properly be a Sergeant-at-Arm, and suggesting that if Carl removes the other one he can simply be a Sergeant. No details of the class's abilities were given on the broadcast.
