Green Alien Controls Earth's Magnetic Field — Amazing Stories Dec 1946

A cold silver helmet studded with vents and goggle-lenses dominates this vivid 1946 Amazing Stories cover, crowning a green-skinned, serene-faced alien whose outstretched hands frame a glowing Earth encircled by a golden electromagnetic torus. The background bleeds from bruised purple at the top into volcanic red-orange below, creating an atmosphere of cosmic menace. The composition suggests absolute planetary control — a supremely confident villain cradling civilization itself like a toy.
