Synopsis
Four heroes are being flown to appear on the radio show "Heroes" when their jet crashes in a storm. Miraculously, all four survive unharmed, even down to a working watch. Since they are "living on borrowed time", they vow to make the best use of it, taking risks to benefit others, challenging the unknown. In their first official case, they are summoned by Morelian, a descendant of Merlin, to open four chambers of a dangerous alchemist's box and "witness things not seen on this Earth since the dawn of Man!"

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 can't be harmed by anything, it must be a thought, so he "thinks" it out of existence. All the while, Morelian flies overhead, watching.

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.

ULTIVAC ends up a stationary calculating machine, his spark gone, yet "still contributing to man's knowledge".

Synopsis
Summoned to a lab, the Challs observe a monkey with super abilities. It was given a pill derived from a meteorite, then boosted into space. Rocky is chosen to take the pill and rockets into space unaware the monkey has lapsed into a coma. The rocket crashes and Rocky emerges with super powers, including freeze rays, super strength, and invisibility, but he becomes irrational. A crook takes Rocky in hoping to use him to rob banks. Rocky's decency wins out and when the Challengers and June appear Rocky shocks the crooks. Grazed by a bullet Rocky recovers his memory and his powers wear off.

Indexer Notes

Rocky's being shot into space, crashing, and exhibiting super-strength, invisibility and fire powers has similarities to Kirby's later co-creations of Reed Richards, Ben Grimm, Sue Storm, and Johnny Storm in Fantastic Four #1.
