Challengers of the Unknown #2

When a burglar with the power to walk through walls stuns the city, the Challengers of the Unknown and their honorary member June Robbins take to the streets to stop him. Their pursuit leads them to an abandoned lab tied to the mysterious Prof. Macon, where the thief, Anton Zammer, plans to exploit long-forgotten inventions for his own ends. Trapped by a shrinking ray and forced to confront the lab’s hidden dangers, June becomes the key to their escape — but the real challenge is just beginning.

When a mysterious spaceship crashes near a remote desert outpost, the Challengers of the Unknown are called in—only to discover three alien creatures imprisoned within. Now, with time running short, the team must decide whether to risk everything to return the beasts to their sealed cages before they break free.

In "The Secret of the Space Monster," a terrifying octopoid entity menaces a starship crew, but when Rick Starr, Myra, and Cryll investigate, they uncover a shocking truth: the monster is a holographic illusion created by rebellious blue-ostrich Korthan forces. Using Cryll’s disguises and an old iron cannon, the trio must unravel the deception before the mirage brings war to Earth and their homeworld.

In "The Riddle of the Lost Race," Space Ranger, Myra, and Cryll pursue a criminal gang across the solar system—from Mars to Saturn and on to Venus—chasing a stolen map leading to the fabled Valley of Ice. When they finally reach the enigmatic Space Sphinx, they must unravel ancient mysteries to uncover the secret of the Sacred Jewel of the Sea.
