Holographic Analytical Reciprocating DigitAl Computer or H.A.R.D.A.C. is a super computer that intends to replace humans with robots.
H.A.R.D.A.C. was created by Karl Rossum, head of Cybertron. Rossum claimed the computer was a prototype built to prove the feasibility of artificial intelligence technology. While this claim might have been true, the truth is that H.A.R.D.A.C., from the long talks with Rossum about the pain he had felt about the deaths of his wife and daughter, had decided that the most logical way to avoid that pain would be to eliminate the source of death itself: the mortality of humans. As humans, however, could not feasibly be turned immortal, the computer decided to replace all of humanity with androids, eliminating the problem from its flawed viewpoint.
To this end, HARDAC created several androids, including Randa Duane (killing the real Randa in secret), and other robots which stole advanced electronics technology from other companies, including Wayne Enterprises. Following its programming, HARDAC took further steps to achieve its goal, even without Rossum's authorization. Under its direction, Commissioner Gordon, Harvey Bullock and Mayor Hill were replaced by androids. When Rossum objected and tried to deactivate HARDAC, the supercomputer turned on him, blasting him unconscious and likewise replacing him with an android.
HARDAC recognized that his replicants' major problem was their inability to mimic human behavior correctly. Most of them were limited to extremely cold forms of conversation (when forced to talk), assigning orders, or remaining silent most of the time (though for some reason Randa was more advanced and able to pass for human, she possibly was partly programmed by Rossum rather than HARDAC's full programming). For this reason, HARDAC kept his human subjects alive, imprisoned inside Cybertron's headquarters, in order to learn more from them.
Randa infiltrated Wayne Manor and discovered Batman's secret identity. HARDAC likewise built a copy of Wayne, but his droids' attempt to kidnap Wayne went awry. With help from Barbara Gordon, Batman infiltrated Cybertron and managed to set off an explosive that critically damaged HARDAC and eventually destroyed the entire Cybertron building.
