Clone Force 99 originated as a batch of clones who were born with "desirable" genetic mutations that made them superior soldiers. These mutations also had the unique effect of altering their appearance and voice greatly from regular clones. Each one of the members acquired certain abilities unique to the team. Due to their genetic mutations, unorthodox fighting tactics, and gung-ho behavior, they were nicknamed the "Bad Batch" within the Clone Army. While part of the army, they earned quite the reputation. The squad worked together with Commander Cody on certain occasions, but did not report to anyone.
