The mad Emperor, warrior descendant of the ravagers of Asia, unleashed a new, horrible, ingenious weapon against the American people. While Mongols bent over a powerful death-machine, a thousand miles away, the air became unbreathable! Men and women and children — all living things — gasped for life-giving oxygen, and with searing, heaving lungs, fell strangled by the mysterious, deadly element. Against these demoniacal hordes, one man alone — Operator #5 — struggles while red revolt and destruction blasts America!
Go with crack Secret Service agent Jimmy Christopher as he meets the challenge of The Green Death Mists, torn from the pages of Operator #5 magazine, November 1934.
