Clone Trooper Sketch

Clone Trooper Sketch.


Sketch wears Standard Phase 1 Clone armor, while his facial appearance consists of having a "high-fade" haircut with long sideburns and a letter "S" tatoo written in Aurebesh on the right-side of his forehead. (To distinguish himself from other Standard Clone Troopers.)


Sketch is one of the very first Clone Troopers to have sideburns. (Aside from Punch and Jester.)
