History[]

Blackrock was a criminal scientist who was given powers by a a parasitic alien lifeform that took the shape of a black rock. Peter Silverstone started out as Director of Research and Technology for the United Broadcasting Company under company president Sam Tanner. Tasked with creating a corporate-backed superhero persona that UBC could cover exclusively, Silverstone created a suit that would give its wearer the power over broadcasting frequencies. Silverstone manipulated various people into wearing the suit and becoming Blackrock, before finally using the persona for himself. He was eventually bludgeoned to death by Samuel Benjamin, who took the suit and power for himself.
