Quoted By:
"Originally created before the Great War by the government and the military to supplement human troops in battle, deathclaws were derived from mixed animal stock, primarily from the very common Jackson Chameleon. They were then soon to be refined by the Master, by using genetic manipulation and the Forced Evolutionary Virus to enhance them as one of his minions. The resulting creature is incredibly fast, powerful with its sharp claws, and almost intelligent"
so they were made by le government
and the master just made them better n refined them
