Meanwhile, the mystery undercover Joe helps another undercover Joe steal a M.A.R.S.-modified Night Raven. With writer Steve Parkhouse, he created the pulp adventure character Night Raven. In Denmark, the night raven is considered an exorcised spirit. He who looks through the hole will become a night raven himself. Night Raven first appeared in "Hulk Comic" #1 (March 7, 1979). "Nycticorax" means "night raven" and derives from the Ancient Greek "nuktos" "night" and "korax", "raven".
