- "No, it's okay, Sarge. I got nothing to hide."
"Gus" was the nickname of a Clone Trooper who served in Clone Trooper Sergeant Slick's platoon during the Clone Wars. In 21 BBY, he was dispatched with a Jedi-led contingent of the Grand Army of the Republic to liberate the planet Christophsis from the Confederacy of Independent Systems. Gus joined his unit on reconnoitering the planet for a strategical ambush site, but the Confederacy was able to ambush the Republic forces. Gus was wounded in the droid attack, and back at the base, he was treated by a Medical Droid. When Clone Captain Rex and Clone Commander Cody interrogated the members of Slick's platoon to locate a possible Confederate spy, Gus stated his alibi without hesitation. Sergeant Slick himself was revealed to be the turncoat and was apprehended.
