12 page Challengers of the Unknown story "Death Guarded the Doom Box"

Characters Ace Morgan; Rocky Davis; Prof Haley; Red Ryan; (Challengers of the Unknown); Burt Langdon and his gang
Synopsis Burt Langdon, a criminal, has stolen the Horn of Herix from a museum. The Challengers track Langdon’s gang to a secret valley where a Doom Box, a legendary weapon, is hidden. Weird boobytraps slow the Challengers: an alligator, a tree-turned-elevator, giant robot Romans. They find the horn, discarded, then the Doom Box guarded by a ring of flames and a two-headed dragon! Ace blows the horn: a ray from the box drives back the dragon and flames. Langdon’s gang attacks, grabs the box, and runs. Ace blows the horn again, and the box explodes. The horn was made to destroy the box if it were moved from its protective ring of flames.

Synopsis Atop a restaurant in Boulder City, Colorado, June Robbins is amazed as objects vanish into thin air. She fetches the Challengers. Little green men run amok in the city, trapping people in glass cylinders. Prof and Rocky pursue. Ace and Red fly to a mysterious cloud that camouflages a flying platform contolled by alien criminals! They’re captured. In the city, Rocky and Prof battle the aliens’ metal insect with a wrecking ball crane. Two new aliens shake the insect to pieces. They’re scientists who commanded the flying platform until criminals seized control. These aliens fly Rocky and Prof to the platform. The Challengers create a diversion, free Ace and Red, and brawl with alien criminals. The good scientists blow jets of air to suspend everyone and dump them in jail! Sorted out, the Challengers bid the good aliens goodbye.
