The dreaded Skull Killer returns! Jeffrey Fairchild, alias kindly Doctor Skull, alias the crime-crushing Skull Killer and the hero of the first issue of The Octopus, is back for another run against the insane leader of the Purple Eyes cult. But this time, the malevolent mastermind is not the Octopus, but his sinister successor, the diabolical Scorpion! Branded with a scorpion symbol on his face, this new titan or terror bids fair to outdo the depredations of his predecessor. All through Manhattan, ordinary citizens are transformed into merciless murderous maniacs. Mother slay their children. Husbands slaughter their wives. And only one hero can halt the madness of Satan's Incubator.
