Notes First appearance of the Challengers of the Unknown. According to Joe Simon and Jack Kirby historians, Jack Kirby brought the proposal for the Challengers to DC. DC bought the concept and folded it into Showcase. Yet the DC Archive cites Dave Wood as the writer. So did Dave Wood rewrite Jack Kirby's dialogue?

6 page Challengers of the Unknown story "The Freezing Sun! [Chapter 3]"

Synopsis Picked up by sailors, Red returns to the island to find the second chamber open and Rocky frozen stiff. The menace is a sentient freezing sun from parts unknown that sucks up all heat, freezing people. Alone, Red cobbles a vacuum chamber and lures the sun inside, trapping it. Meanwhile, out on the water, Prof realizes that, since the Dragon Seed Giant cant be harmed by anything, it must be a thought, so he "thinks" it out of existence. All while Morelian flies overhead, watching.

6 page Challengers of the Unknown story "The Whirling Weaver! [Chapter 4]"

Synopsis The third menace is a tube that releases a whirling weaver. Out of control, it spins ribbons that snarl entire cities. The Challs pursue, then discover a dial on the weaver's tube and slow it to a halt. Returning to the island, they find Morelian has opened the fourth chamber for his own selfish reasons. He got a diamond ring of immortality: he'll live forever. Except the inscription on the box is vague, "contained in me, find immortality". Morelian flies off, but his plane stalls and crashes, killing himself and destroying the box. The box granted immortality: the ring was certain death. The Challengers fly off, asking, "I wonder what what's ahead of us now?"
