Challengers of the Unknown #1

In "The Sorceress of Forbidden Valley," a crash-landed June Robbins stumbles upon an ancient lamp in a hidden cave, unleashing fumes that cloud her mind. When the Challengers of the Unknown—Ace Morgan, Professor Haley, Red Ryan, and Rocky Davis—track her to a mysterious valley, they’re ambushed by strange forces and discover June transformed, her actions guided by the sinister Charles Agar. As the residents of the Forbidden Valley watch in silence, the team must unravel the truth behind the sorcery before it’s too late.

When the Challengers of the Unknown respond to a distress call, they're ensnared by the Stupendous Interplanetary Circus and forced into brutal performances as captives. Trapped in a cage with other alien performers, they face the monstrous Quadro the Four-Finned Demons in a deadly arena. With the circus’s true nature revealed and their strength amplified by the strange atmosphere, the heroes must find a way to turn the tide before the circus’s criminal masters crush them.

In "Mystery of the Mental Menace!", Adam Strange finds himself drawn to the distant planet Rann when a mysterious magnetic meteor disrupts his usual missions. There, he encounters Alanna and faces the enigmatic Zakkad, a villain with a dangerous plan to steal the secret of teleportation and use it to dominate the universe.
