Spanner, a corporal within the Grand Army of the Republic, was a clone trooper who fought in the Clone Wars. Alongside Sergeant Joker, Spanner was assigned to the hangar of the Jedi Temple. Spanner frequently failed to grasp the jokes that Joker, in an attempt to alleviate boredom, would tell. Furthermore, both clones were stationed at the Iceberg Three Republic outpost during the Mission to Iceberg Three.
