Clone Force 99, informally known as «The Bad Batch,» was a clone commando squad during the Clone Wars. The squad consisted of four clone troopers designed with genetic mutations. «Crosshair,» a clone with eyesight and marksmanship that allowed him to excel in long distance firefights, «Wrecker,» a reckless clone with enhanced muscular form, and «Tech,» a clone with enhanced mental capacity and intelligence. They were led by Clone Sergeant «Hunter,» a clone with enhanced sensory abilities. Following the Battle of Anaxes, Clone Corporal «Echo» joined the squad.
