Showcase #6
☆ Be the first to review + Add to your collection — Join freeShowcase #6 marks the debut of the Challengers of the Unknown — Ace Morgan, Prof Haley, Rocky Davis, and Red Ryan — making it the first appearance of a Silver Age super-team and, by most accounts, the first wholly original concept to emerge from DC's celebrated try-out anthology. The team's defining premise — four specialists who survive a plane crash and dedicate their 'borrowed time' to confronting the unknown — introduced an existential undertone to adventure comics that was strikingly novel for 1957, and it arrived just two issues after Barry Allen's Flash had signaled the Silver Age's beginning. Many historians argue that Kirby later reworked the concept's core DNA with Stan Lee to produce the Fantastic Four in 1961, giving this issue an outsized influence on the entire Marvel Age that followed.
In "The Secrets of the Sorcerer's Box! [Chapter 1]," Jack Kirby, Joe Simon, and Dave Wood launch a thrilling mystery with Kirby’s dynamic art and inks bringing to life a surreal, high-stakes adventure. The Challengers face a bizarre new threat — a spinning tube that weaves city-entangling ribbons — only to uncover a hidden dial and a dangerous truth behind the box’s fourth chamber. With Kirby’s cover art capturing the eerie grandeur of the sorcerer’s device, this 1957 Showcase #6 is a standout early showcase of the creative team’s inventive storytelling.
When a storm forces a jet carrying four heroes down, they emerge unscathed—down to the second on their watches—prompting them to embrace their unexpected reprieve with daring acts of courage. Summoned by Morelian, a descendant of Merlin, they now face their first true test: unlocking the four chambers of a sorcerer’s box and confronting wonders beyond mortal understanding.
In "Chapter Two: Dragon Seed!" from Showcase #6 (1957), the Challs bring their mysterious box to a tropical island, where they draw straws to open the next chamber. When the first chamber is cracked, a legendary stone giant hatches from a "Dragon's Egg," terrorizing the seas and surviving an atom bomb blast. Now, with the island still trembling and the next chamber waiting, Rocky prepares to face whatever lies within.
In "Chapter Three: The Freezing Sun!", Red returns to the island to confront a terrifying, sentient sun that drains all heat, leaving everything frozen—including Rocky. With no help but his wits, Red builds a vacuum chamber to trap the icy menace, while on the water, Prof pieces together the mystery of the invincible Dragon Seed Giant, realizing it must be a thought—and then, he thinks it away. Above it all, Morelian watches, silent and unseen.
In "Chapter Four: The Whirling Weaver!", the Challengers face a city-entangling menace spun from a mysterious tube, only to uncover a hidden dial that halts the chaos. Back on the island, Morelian’s greed leads him to open the fourth chamber, claiming a diamond ring of immortality—only to find the truth is far more deadly than he imagined.

The issue appeared on newsstands in late 1956 with a cover date of January/February 1957, edited by Jack Schiff, and ran without any writer credits. Scholars credit Jack Kirby as the driving creative force — Kirby is believed to have brought the team concept to DC himself — but the scripting question remains genuinely unsettled: Kirby historian and comics journalist Mark Evanier suspects the first issue was scripted primarily by Kirby and Joe Simon, while Dave Wood is cited as the writer in DC's own Archive edition credits, and the Comics Journal identified a Kirby-and-Dave-Wood collaboration. Inking credits are similarly contested: the DC Archive lists Marvin Stein, but Stein himself denied the assignment in conversations with researcher Greg Theakston, and Evanier and Nick Caputo both note evidence that Kirby may have inked some pages himself.
