The Star Marshals are known to have been enemies to the evil Ra Moon and its creations, the Stardroids and Kuiper Droids. Over 20,000 years ago, the Star Marshals launched a devastating assault on one of Ra Moon's fortresses, engaging the Stardroids in battle. However, they detected Ra Moon escaping in the custody of several Kuiper Droids, and two of their members, Trio and Quartet, attack them. The Kuiper Droids were decimated, with only the one who would become Shadow Man surviving, but Star Marshal Trio chose at that moment to betray Quartet, attacking him and allowing Ra Moon and Shadow Man to escape.
