Drake was a clone who served under the Galactic Republic, and temporarily the Galactic Empire. He was cloned as part of an elitist group of clones, Destructive Ranged Army Killers, or D.R.A.K.. The D.R.A.K. had more free will then most clones, even more than the ARC troopers, which gave them an advantage in various circumstances, they were also cloned with more endurance then others. The D.R.A.K. were a faction of clones that were trained under extreme circumstances that most clones would not survive, in fact it took months of development of clones in the D.R.A.K. project for the first clone to finally pass the training, Alpha 254.
