In issue 42, it is revealed that over 20,000 years before he became Shadow Man he was part of an alien line of robots called Kuiper Droids that served Ra Moon and the Stardroids. When the Star Marshals attacked Ra Moon, Terra gave the Kuiper Droids orders to escort their master to safety, but they were all destroyed, except for Shadow Man, who manages to land on Earth with Ra Moon, but he goes offline. Shadow Man and Ra Moon's survival was enabled by the treachery of the Star Marshal known as Trio, who murdered his compatriot Quartet.
