After being detected while stealing top secret documents from the United States government, the alien invaders known as the Space Prowlers came into conflict with Captain Atom. The intruders provided the hero with his first real challenge, armed as they were with laser weapons capable of weakening and even killing Captain Atom. The murderous Space Prowlers attempted to ambush the Captain with a fleet of small ships, but were eradicated in a nuclear explosion created by the hero. Captain Atom then located their mother ship in the region, and destroyed it from afar, seemingly ending the threat of the Space Prowlers.
