Challengers of the Unknown #24

In "The Challengers Die at Dawn," the Challengers of the Unknown track down the scam-artist Manfredo through the jungles of Southeast Asia, only to be captured and sentenced to die at dawn by offended tribespeople. As Prof, Red, and Rocky face deadly trials by combat—each aided by a mysterious ally—Ace and June uncover the truth: Manfredo was already dead, and his hidden hand was ensuring his own demise would be reported. The team reunites, unravels the deception, and brings the real culprit to justice before heading home.

In "Multi-Man, Master of Earth!" from Challengers of the Unknown #24, the shape-shifting villain Multi-Man unleashes his newfound powers as an energy being, transforming into a floating moon-man and a sponge-man to outwit Ace and Rocky. As he sets his sights on dominating Earth, the Challengers race to stop him—only for Red and June to free their teammates and confront the fugitive in a high-stakes showdown that ends with a crash into a mountain and a sudden loss of memory.
