SHOWCASE Vol 1 #6 (Feb 1957)
Title: The Secret of the Sorcerer’s Box
Villains: Morelian and creatures from Pandora’s Box
Synopsis: In this origin story, wrestling champion Rocky Davis, scuba diving marine biologist Professor Walter Haley, war veteran jet pilot Ace Morgan and circus daredevil Red Ryan miraculously survive a plane crash. Deciding that the odds of them surviving were so low they consider themselves living on borrowed time. They devote themselves to challenging the unknown.

The crew members we meet in this debut story – 1. Captain Jordan Shaw (right), a decent man appalled at the way the Six have chosen to play God with who gets to escape and who gets left behind to die. He cooperates just so he and his wife can survive, so he bitterly knows he is no better than the oligarchs in the end.
And 5. Phaedra (left), a mutant with telekinetic and telepathic abilities. She and Earth’s hundreds of other mutants live in prison camps at the Six’s command while their abilities are probed. They are all forced to wear facial tattoos to prevent them hiding their mutant status.
