- "If you take good care of your weapon, it will take good care of you."
- ―Jester's motto
Jester was a clone trooper in Slick's platoon. He was sent to Christophsis to help free the planet from the Separatists along with others such as Gus, Chopper, Punch, Sketch and Hawk. Jester joined his unit on reconnoitering the planet for a strategical ambush site, but the Confederacy was able to ambush the Republic forces. After the clone troopers returned to the base, Jester cleaned his blaster, as he did after every battle. When Clone Captain Rex and Clone Commander Cody interrogated the members of Slick's platoon to locate a possible Confederate spy, Jester was nervous about talking to his commanding officers, but fellow trooper Sketch vouched for him, and Jester was able to verify his alibi. Sergeant Slick himself was later revealed to be the turncoat and was apprehended.
