According to the Batcomputer, a duplicant was "a life-like robot capable of mimicking human behavior". They were the creations of the artificial intelligence known as H.A.R.D.A.C.. Since Karl Rossum was the creator of H.A.R.D.A.C., duplicants were, in a sense, Rossum's "grandchildren".
H.A.R.D.AC. wished to replace all of humanity with duplicants, but was thwarted on two separate occasions. In the first instance, it was blown up by Batman. When it later tried to rebuild itself by transferring its matrices into the Batcomputer, the Batman duplicant destroyed it before the upload could be completed.
