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.

After attracting publicity over some minor escapades, the Challengers of the Unknown are hired by millionaire Mr. Morelian to open Pandora’s Box and survive. Our heroes take the box to a remote desert island and open the relic.

EERIE #62 (Jan 1975)
FIRE-EATER
Powers: Fire-Eater, as his name would imply, could “eat” and suck in large flames as well as blow fire-blasts from his mouth. He was also impervious to fire and was skilled at unarmed combat.

THE BRICK MOON (1872) – Written by Edward Everett Hale, best known for The Man without a Country. This novella started out as a serialized story published in 1869 in the October, November and December issues of Atlantic Monthly. A follow-up installment, titled Life in the Brick Moon, was published in the February 1870 issue.
The story begins in the 1840s when Frederic Ingham, the tale’s narrator, and his college friends Orcutt and Halliburton plan a dream project which winds up taking decades to fulfill – a manmade artificial satellite, the first recorded in science fiction stories.
THE VOYAGE OF MAEL DUIN (Immram curaig Mail Duin) – Dated to around the late 900s A.D. or earlier, this story deals with the epic quest of Mael Duin (aka Maildun and Maeldune) and the crew of his ship as he seeks revenge on his father’s killers. This lengthy epic deserves to be as well-known as the Odyssey or the Quest for the Golden Fleece.
Mael Duin matured, and proved better than his presumed siblings at athletic, martial and academic competitions. Losing their temper over this, one of our hero’s foster brothers ridiculed Mael Duin for not even knowing who his real father and mother were. 
CONAN THE BARBARIAN Vol 1 #52 (Jul 1975)
Conan finds the Ring of the Black Shadow, thus animating a huge statue of the Scorpion God which guards the ring to keep it out of human hands. Our hero fights the statue and renders it inert again with a sword through its “brain.”
