Blackrock is a fictional supervillain in the DC Comics universe. Blackrock is a recurring enemy of Superman first appearing in Action Comics (April 1976).
Blackrock was the creation of Dr. Peter Silverstone in an attempt to increase ratings for the United Broadcasting television network. Silverstone hypnotized UB President Sam Tanner and later Tanner's nephew, Les Vegas, to fill the role. A third Blackrock (an energy construct) was created by Tanner's command not much later.
However, it is known that eventually Silverstone assumed the mantle of Blackrock himself, using a powerful stone that could metabolize electromagnetic energy into energy to achieve flight, energy blasts and superhuman strength, and fought Superman several times. This rock, while a technological artifact, has the appearance of a polished gem that is as black as coal. It was appropriately dubbed the Blackrock.
